A brief scalable suicide risk assessment tool accurately predicts suicide risk in patients with serious mental illness (SMI), a new population-based study shows.

The 17-question Oxford Mental Illness and Suicide Tool (OxMIS) assessment is designed to predict 12-month suicide risk in people with schizophrenia spectrum disorders and bipolar disorder based on risk factors such as familial traits, antisocial traits, and information about self-harm.

“We have demonstrated the clinical utility of OxMIS in two separate studies and countries. As with any clinical risk prediction tool, it will not improve outcomes unless coupled with effective interventions,” lead investigator Amir Sariaslan, PhD, a senior research fellow in psychiatric epidemiology at the University of Oxford, England, told this news organization.

The findings were published online in Translational Psychiatry.
 

Twice validated

Dr. Sariaslan and his team originally developed and validated the OxMIS in a cohort of 75,000 people with SMI in Sweden. Recognizing the lack of externally validated prognostic models in the mental health field, the team wanted to validate the instrument in a new, population-based sample in Finland.

The investigators accessed information about patient diagnosis and treatment from the Finnish Care Register for Health Care, which contains de-identified information for all individuals between ages 15 and 65 years diagnosed with an SMI between Jan. 1, 1996, and Dec. 31, 2017.

They included 137,000 patients with somatic symptom disorder or bipolar disorder for a total of more than 5 million episodes of inpatient or outpatient treatment. Investigators linked the cohort to the Causes of Death Register to identify those who had died by suicide within 12 months of an index treatment episode, which investigators randomly selected for each person.

The investigators found that 1,475 individuals in the sample died by suicide within 1 year of their index episode (1.1%).

Each patient was assigned a clinical suicide risk score based on their clinical information, familial traits, prescription information, and comorbid conditions. Using OxMIS, the investigators found that the instrument accurately predicted suicide with an area under the curve of 0.70.

In other words, in 70% of the instances where the investigators randomly selected two people from the sample, one of whom died by suicide and the other of whom did not, the individual who died by suicide had a higher OxMIS risk score.

The investigators note the model overestimated the risk for patients who were at extremely high risk for suicide (those with a predicted suicide risk of > 5%). “In our complementary sensitivity analysis, we observed improved calibration in these patients when we assigned them a suicide risk prediction of no more than 5%,” they write.

Dr. Sariaslan said that the findings highlight the importance of safety planning interventions. “It is also essential to remember that OxMIS is not intended to replace clinical decision-making, but rather to support it,” he said.

As to whether the tool could be used in other populations, such as in the United States, Dr. Sariaslan said, “there is no good evidence that the contribution of risk factors to suicide in this population is different in the U.S. than in northern Europe, so there is no a priori reason to have to do multiple external validations before it can be used for research or clinical purposes.”
 

One size does not fit all

Commenting on the study, Ronald Kessler, PhD, McNeil Family Professor, department of health care policy at Harvard Medical School, Boston, said that he’d be “surprised” if OxMIS was adopted in the United States because there is already an existing tool that is “slightly more accurate,” which he helped develop.

“In addition, when we start thinking about uses for such scales, it becomes clear that different scales should be used for different segments of the population, depending on intervention options,” Dr. Kessler said.

“So, for example, a different scale would probably be optimal in deciding how to manage psychiatric inpatients in the transition back to the community after hospital discharge than [it would be], say, in deciding how to respond to suicidality among patients presenting at an emergency department. No one scale will fit for all the scenarios in which prediction is desired,” he added.

The study was funded by the Academy of Finland. Dr. Kessler receives funding from the National Institute of Mental Health, Department of Defense, and Veterans Administration to develop suicide prediction models. Dr. Sariaslan has no disclosures to report.

BOSTON – Results of a phase 2 study demonstrate potential Alzheimer’s disease–modifying effects of an investigational oral antiamyloid agent, represented by positive changes in plasma and imaging biomarkers of Alzheimer’s disease pathology.

Use of the drug, ALZ-801 (Alzheon), led to a significant reduction of plasma phosphorylated–tau 181 (p-tau₁₈₁) , a marker of amyloid-induced neuronal injury in Alzheimer’s disease, as well as slowing of hippocampal atrophy and stabilization of cognition.

“The 12-month results of our phase 2 trial support the finding that ALZ-801 blocks misfolding of amyloid monomers and subsequent formation of neurotoxic amyloid oligomers, the key initial step in the amyloid aggregation cascade, which leads to a rapid and sustained reduction of brain neurodegeneration as measured by plasma p-tau₁₈₁,” John Hey, PhD, Alzheon’s chief scientific officer, said in a statement.

“The severalfold greater reduction on the p-tau₁₈₁ biomarker in plasma compared to plaque-clearing antiamyloid antibodies, combined with preservation of brain hippocampal volume and their positive correlations with cognitive benefits, further validate the disease-modifying effects of ALZ-801 in Alzheimer’s patients,” Dr. Hey added.

The results were presented at the 2023 annual meeting of the American Academy of Neurology.
 

ALZ-801 is an optimized prodrug of tramiprosate that has been shown to inhibit amyloid-beta 42 aggregation into toxic oligomers.

The ongoing phase 2 study is evaluating the effects of oral ALZ-801 (265 mg twice daily) on biomarkers of Alzheimer’s disease pathology for 84 adults with early Alzheimer’s disease who have either the APOE4/4 or APOE3/4 genotype. These genotypes represent the majority of patients with Alzheimer’s disease.

The mean age of the cohort was 69 years, and 51% are women; 70% had mild cognitive impairment, and 30% had mild Alzheimer’s disease. The mean Mini-Mental State Examination score for the cohort was 26.0. Roughly half were taking a cholinesterase inhibitor.

Significant plasma p-tau₁₈₁ reduction was observed at 13 weeks. Levels were reduced by 41% by 52 weeks (P = .016). There was also a significant 5% reduction in plasma amyloid-beta 42 and 40 at 52 weeks (P = .002 and P = .005, respectively), Dr. Hey reported.

After 12 months of treatment, hippocampal atrophy was reduced by about 23%, and expansion of ventricular volume was reduced by about 15%, both in comparison with matched controls from the Alzheimer’s Disease Neuroimaging Initiative.

Composite cognitive z-score improved significantly at 13 and 26 weeks and remained above baseline at 52 weeks in comparison with matched ADNI controls. “These are very promising data,” Dr. Hey told conference attendees.

He noted that the safety profile of ALZ-801 remains favorable and consistent with prior safety data. Common adverse events were mild nausea and SARS-CoV-2 infection. There were no drug-related serious events or amyloid-related imaging abnormalities–edema (ARIA-E).

The phase 3 APOLLOE4 study of ALZ-801 is underway. This double-blind, randomized study is comparing oral ALZ-801 with placebo over 78 weeks for roughly 300 adults with early Alzheimer’s disease who have the APOE4/4 genotype. APOLLOE4 is expected to be completed in mid 2024.

The APOLLOE4 study is supported by a $47 million grant from the National Institute on Aging. The U.S. Food and Drug Administration has granted ALZ-801 fast-track designation.
 

More accessible option?

Reached for comment, Percy Griffin, PhD, Alzheimer’s Association director of scientific engagement, noted that the “biggest difference between this drug and others is that it is taken orally, rather than delivered through an infusion. This is important and valuable for reducing patient and caregiver burden and increasing ease of use and access.”

It’s also noteworthy that ALZ-801 was not associated with ARIA-E, “which has been reported in other antiamyloid trials and can occasionally be serious,” Dr. Griffin said.

Overall, he said the results are “encouraging, but more work is needed. If studies results continue to be positive, this treatment may provide a more accessible option for people who are at higher risk of ARIA,” Dr. Griffin said.

The study was funded by Alzheon. Dr. Hey is an employee of Alzheon and holds stock in the company. Dr. Griffin has disclosed no relevant financial relationships.

Initiation of buprenorphine in hospitals in the United States has plateaued since 2018, with low retention rates of less than 25%, based on data from more than 3 million individuals who began buprenorphine between January 2016 and October 2022.

University of Michigan

Opioid overdose deaths are at a record high in the United States, and many of these deaths can be prevented with medications such as buprenorphine, said lead author Kao-Ping Chua, MD, of the University of Michigan, Ann Arbor, in an interview. “However, buprenorphine cannot prevent opioid overdose deaths if patients are never started on the medication or only stay on the medication for a short time. For that reason, rates of buprenorphine initiation and retention are critical metrics for measuring how well the U.S. health care system is responding to the opioid epidemic,” he said.

“At the time we started our study, several other research groups had evaluated U.S. rates of buprenorphine initiation and retention using data through 2020. However, more recent national data were lacking,” Dr. Chua told this news organization. “We felt that this was an important knowledge gap given the many changes in society that have occurred since 2020,” he noted. “For example, it was possible that the relaxation of social distancing measures during 2021 and 2022 might have reduced barriers to health care visits, thereby increasing opportunities to initiate treatment for opioid addiction with buprenorphine,” he said.

Dr. Chua and colleagues used data from the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed from retail pharmacies in the United States. “Buprenorphine products included immediate-release and extended-release formulations approved for opioid use disorder but not formulations primarily used to treat pain,” they write.

Monthly buprenorphine initiation was defined as the number of patients initiating therapy per 100,000 individuals. For retention, the researchers used a National Quality Forum-endorsed quality measure that defined retention as continuous use of buprenorphine for at least 180 days.

A total of 3,006,629 patients began buprenorphine therapy during the study period; approximately 43% were female.

During the first years of the study period, from January 2016 through September 2018, the monthly buprenorphine initiation rate increased from 12.5 per 100,000 to 15.9 per 100,000, with a statistically significant monthly percentage change of 0.62% (P < .001).

However, from October 2018 through October 2022, the monthly percentage remained essentially the same (P = .62) with a monthly percentage change of −0.03%.

From March 2020 through December 2020, the median monthly buprenorphine initiation rate was 14.4 per 100,000, only slightly lower than the rates from January 2019 through February 2020 and from January 2021 through October 2022 (15.5 per 100,000 and 15.0 per 100,000, respectively).

Over the entire study period from January 2016 through October 2022, the median monthly retention rate for buprenorphine use was 22.2%. This rate increased minimally, with no significant changes in slope and a monthly percentage change of 0.08% (P = .04).

The study findings were limited by several factors, including a lack of data on race and ethnicity, in-clinic administration of buprenorphine, and buprenorphine dispensing through methadone outpatient programs, the researchers note. Also, data did not indicate whether some patients began buprenorphine to treat pain, they say. The timing of the flattening of buprenorphine use also suggests the influence of factors beyond the COVID-19 pandemic, they write.

However, the results were strengthened by the large sample size and suggest that efforts to date to increase buprenorphine use have been unsuccessful, the researchers write. “A comprehensive approach is needed to eliminate barriers to buprenorphine initiation and retention, such as stigma and uneven access to prescribers,” they conclude.
 

Study highlights underuse of buprenorphine option

“Our study shows that buprenorphine initiation rates have been flat since the end of 2018 and that rates of 180-day retention in buprenorphine therapy have remained low throughout 2016-2022,” Dr. Chua told this news organization. “Neither of these findings are particularly surprising, but they are disappointing,” he said. “There were a lot of policy and clinical efforts to maintain and expand access to buprenorphine during the COVID-19 pandemic, such as allowing buprenorphine to be prescribed via telehealth without an in-person visit and eliminating training requirements for the waiver that previously was required to prescribe buprenorphine.

“The fact that buprenorphine initiation and retention did not rise after these efforts were implemented suggests that they were insufficient to meet the rising need for this medication,” he said.

The current study “adds to a growing body of research suggesting that clinicians are not maximizing opportunities to initiate buprenorphine treatment among patients with opioid addiction,” Dr. Chua said. He cited another of his recent studies in which 1 in 12 patients were prescribed buprenorphine within 30 days of an emergency department visit for opioid overdose from August 2019 to April 2021, but half of patients with emergency department visits with anaphylaxis were prescribed anepinephrine auto-injector.

“My hope is that our new study will further underscore to clinicians how much the health care system is underusing a critical tool to prevent opioid overdose deaths,” he said.

The federal government’s recent elimination of the waiver needed to prescribe buprenorphine may move the needle, but to what degree remains to be seen, Dr. Chua added. “It is possible this intervention will be insufficient to overcome the many other barriers to buprenorphine initiation and retention, such as stigma about the drug among clinicians, patients, and pharmacists,” he said.
 

Lack of education remains a barrier to buprenorphine use

The current study is important to determine whether attempts to increase buprenorphine initiation and treatment retention are working, said Reuben J. Strayer, MD, director of addiction medicine in the emergency medicine department at Maimonides Medical Center, New York, in an interview.

Dr. Strayer was not involved in the current study, but said he was surprised that initiation of buprenorphine didn’t decrease more dramatically during the pandemic, given the significant barriers to accessing care during that time.

However, “efforts to increase buprenorphine initiation and retention have not been sufficiently effective,” Dr. Strayer said. “The rise of fentanyl as a primary street opioid, replacing heroin, has dissuaded both patients and providers from initiating buprenorphine for fear of precipitated withdrawal.”

The elimination of the DATA 2000 (X) waiver was the removal of a potential barrier to increased buprenorphine use, said Dr. Strayer. “Now that the DATA 2000 (X) waiver has been eliminated, the focus of buprenorphine access is educating primary care and inpatient providers on its use, so that patients with OUD [opioid use disorder] can be treated, regardless of the venue at which they seek care,” he said.

Looking ahead, “The priority in buprenorphine research is determining the most effective way to initiate buprenorphine without the risk of precipitated withdrawal,” Dr. Strayer added.

The study was supported in part by the Benter Foundation, the Michigan Department of Health and Human Services, and the Susan B. Meister Child Health Evaluation and Research Center in the department of pediatrics at the University of Michigan. Dr. Chua was supported by the National Institute on Drug Abuse. Dr. Strayer has disclosed no relevant financial relationships.

Opioid overdose deaths are at a record high in the United States, and many of these deaths can be prevented with medications such as buprenorphine, said lead author Kao-Ping Chua, MD, of the University of Michigan, Ann Arbor, in an interview. “However, buprenorphine cannot prevent opioid overdose deaths if patients are never started on the medication or only stay on the medication for a short time. For that reason, rates of buprenorphine initiation and retention are critical metrics for measuring how well the U.S. health care system is responding to the opioid epidemic,” he said.

“At the time we started our study, several other research groups had evaluated U.S. rates of buprenorphine initiation and retention using data through 2020. However, more recent national data were lacking,” Dr. Chua told this news organization. “We felt that this was an important knowledge gap given the many changes in society that have occurred since 2020,” he noted. “For example, it was possible that the relaxation of social distancing measures during 2021 and 2022 might have reduced barriers to health care visits, thereby increasing opportunities to initiate treatment for opioid addiction with buprenorphine,” he said.

Dr. Chua and colleagues used data from the IQVIA Longitudinal Prescription Database, which reports 92% of prescriptions dispensed from retail pharmacies in the United States. “Buprenorphine products included immediate-release and extended-release formulations approved for opioid use disorder but not formulations primarily used to treat pain,” they write.

Monthly buprenorphine initiation was defined as the number of patients initiating therapy per 100,000 individuals. For retention, the researchers used a National Quality Forum-endorsed quality measure that defined retention as continuous use of buprenorphine for at least 180 days.

A total of 3,006,629 patients began buprenorphine therapy during the study period; approximately 43% were female.

During the first years of the study period, from January 2016 through September 2018, the monthly buprenorphine initiation rate increased from 12.5 per 100,000 to 15.9 per 100,000, with a statistically significant monthly percentage change of 0.62% (P < .001).

However, from October 2018 through October 2022, the monthly percentage remained essentially the same (P = .62) with a monthly percentage change of −0.03%.

From March 2020 through December 2020, the median monthly buprenorphine initiation rate was 14.4 per 100,000, only slightly lower than the rates from January 2019 through February 2020 and from January 2021 through October 2022 (15.5 per 100,000 and 15.0 per 100,000, respectively).

Over the entire study period from January 2016 through October 2022, the median monthly retention rate for buprenorphine use was 22.2%. This rate increased minimally, with no significant changes in slope and a monthly percentage change of 0.08% (P = .04).

The study findings were limited by several factors, including a lack of data on race and ethnicity, in-clinic administration of buprenorphine, and buprenorphine dispensing through methadone outpatient programs, the researchers note. Also, data did not indicate whether some patients began buprenorphine to treat pain, they say. The timing of the flattening of buprenorphine use also suggests the influence of factors beyond the COVID-19 pandemic, they write.

However, the results were strengthened by the large sample size and suggest that efforts to date to increase buprenorphine use have been unsuccessful, the researchers write. “A comprehensive approach is needed to eliminate barriers to buprenorphine initiation and retention, such as stigma and uneven access to prescribers,” they conclude.
 

Study highlights underuse of buprenorphine option

“Our study shows that buprenorphine initiation rates have been flat since the end of 2018 and that rates of 180-day retention in buprenorphine therapy have remained low throughout 2016-2022,” Dr. Chua told this news organization. “Neither of these findings are particularly surprising, but they are disappointing,” he said. “There were a lot of policy and clinical efforts to maintain and expand access to buprenorphine during the COVID-19 pandemic, such as allowing buprenorphine to be prescribed via telehealth without an in-person visit and eliminating training requirements for the waiver that previously was required to prescribe buprenorphine.

“The fact that buprenorphine initiation and retention did not rise after these efforts were implemented suggests that they were insufficient to meet the rising need for this medication,” he said.

The current study “adds to a growing body of research suggesting that clinicians are not maximizing opportunities to initiate buprenorphine treatment among patients with opioid addiction,” Dr. Chua said. He cited another of his recent studies in which 1 in 12 patients were prescribed buprenorphine within 30 days of an emergency department visit for opioid overdose from August 2019 to April 2021, but half of patients with emergency department visits with anaphylaxis were prescribed anepinephrine auto-injector.

“My hope is that our new study will further underscore to clinicians how much the health care system is underusing a critical tool to prevent opioid overdose deaths,” he said.

The federal government’s recent elimination of the waiver needed to prescribe buprenorphine may move the needle, but to what degree remains to be seen, Dr. Chua added. “It is possible this intervention will be insufficient to overcome the many other barriers to buprenorphine initiation and retention, such as stigma about the drug among clinicians, patients, and pharmacists,” he said.
 

Lack of education remains a barrier to buprenorphine use

The current study is important to determine whether attempts to increase buprenorphine initiation and treatment retention are working, said Reuben J. Strayer, MD, director of addiction medicine in the emergency medicine department at Maimonides Medical Center, New York, in an interview.

Dr. Strayer was not involved in the current study, but said he was surprised that initiation of buprenorphine didn’t decrease more dramatically during the pandemic, given the significant barriers to accessing care during that time.

However, “efforts to increase buprenorphine initiation and retention have not been sufficiently effective,” Dr. Strayer said. “The rise of fentanyl as a primary street opioid, replacing heroin, has dissuaded both patients and providers from initiating buprenorphine for fear of precipitated withdrawal.”

The elimination of the DATA 2000 (X) waiver was the removal of a potential barrier to increased buprenorphine use, said Dr. Strayer. “Now that the DATA 2000 (X) waiver has been eliminated, the focus of buprenorphine access is educating primary care and inpatient providers on its use, so that patients with OUD [opioid use disorder] can be treated, regardless of the venue at which they seek care,” he said.

Looking ahead, “The priority in buprenorphine research is determining the most effective way to initiate buprenorphine without the risk of precipitated withdrawal,” Dr. Strayer added.

The study was supported in part by the Benter Foundation, the Michigan Department of Health and Human Services, and the Susan B. Meister Child Health Evaluation and Research Center in the department of pediatrics at the University of Michigan. Dr. Chua was supported by the National Institute on Drug Abuse. Dr. Strayer has disclosed no relevant financial relationships.

Researchers have identified four distinct clinical profiles for young people at risk for serious self-harm. The profiles were developed from their study of children and adolescents aged 5-18 years who had been admitted with a neuropsychiatric event to two children’s hospitals.

The researchers used Bayesian regression to identify the profiles developed from 32 covariates: age, sex, and 30 mental health diagnostic groups from April 2016 to March 2020. The profiles include low-, moderate-, high- and very-high-risk categories.

The study, led by Mert Sekmen with the division of hospital medicine at Monroe Carell Jr. Children’s Hospital, and a student at Vanderbilt University Medical Center in Nashville, Tenn., included 1,098 children, average age 14. Of those, 406 (37%) were diagnosed with a self-harm event.

Traditionally, single diagnoses have been linked with risk of self-harm, independent of other comorbidities, but this study gauges risk for a set of diagnoses.

Findings were published online in Pediatrics.

The risk groups were described as follows:

• Low risk. (45% of the study population; median risk of 0.04 (interquartile range, 0.03-0.04; odds ratio, 0.08). The group included children aged 5-9 years with a non–mental health diagnosis, and without mood, behavioral, psychotic, developmental, trauma, or substance-related disorders.
• Moderate risk. (8% of the study group). This group had the same risk as the baseline risk for the entire cohort (37%) and served as the reference group, with a median risk of 0.30 (IQR, 0.27-0.33). This profile was characterized by several mood disorders and behavioral disorders but without depressive disorders.
• High risk. (36%) This group had an average risk of 0.69 (IQR, 0.67-0.71; OR, 5.09). This profile included female adolescents ages 14-17 with depression and anxiety in conjunction with substance- and trauma-related disorders. Personality and eating disorders were significant in this group. Importantly, the authors wrote, the high-risk group did not include behavioral and developmental disorders.
• Very high risk. (11%) The very-high-risk profile had the highest average risk of 0.79 (IQR, 0.73-0.79; OR, 7.21) and included male children aged 10-13. This profile, like the high-risk profile, included anxiety and depressive disorders. The very-high-risk profile differed from the high-risk with its inclusion of bipolar disorder; attention-deficit/hyperactivity disorder; and trauma-related and developmental disorders such as autism spectrum disorder or intellectual disability, along with conduct disorders. Neither the high- nor the very-high-risk profiles included a concurrent non–mental health diagnosis.

Differences by sex

The authors explained some of the differences by sex. They noted that in a study of children aged 5-11, deaths by suicide were more prevalent among boys. A mental health diagnosis was identified in 31%, the most common being ADHD, depression, and other unspecified co-occurring disorders.

“The very-high-risk group also reflects a concerning rise in death by suicide among (males) aged 10-13, who have seen rates nearly triple from 2007 to 2017,” the authors wrote.

The authors pointed out that, although incidence of anxiety and depressive disorders between male and female children is much the same before adolescence, “female adolescents are twice as likely to be diagnosed with either disorder during adolescence. Girls also have higher rates of suicidal ideation and attempts after puberty.”

Eating disorders were also included in the high-risk profile. A study showed that emergency department visits for adolescent girls attempting suicide were 51% higher from February to March 2021, compared with the same period in the pre-COVID-19 year 2019.

Jason Lewis, PhD, psychologist and section director of mood, anxiety and trauma disorders in the department of child and adolescent psychiatry and behavioral sciences at Children’s Hospital of Philadelphia, who was not part of the research team, said the “constellations of risk factors put into acuity levels” helps to better project risk than knowing the risk associated with a particular diagnosis.
 

Gap closing between young children, adolescents

Dr. Lewis said he was surprised by the young age of 10-13 among the boys in the highest-risk category. That speaks to the differences from standard thinking this paper points out, he said. “Generally, we think about adolescents as being at the highest risk of suicide death and suicidal behavior,” he said.

Dr. Lewis said it’s important to note that the authors acknowledge these profiles are not static. He gave an example that the rate of suicide deaths among females is rising.

“As things like that change, some of these risk profiles will change as well.”

Dr. Lewis said the profiles may be especially helpful to medical providers in emergency departments or those making discharge decisions who don’t have an ongoing relationship with a patient.

The information could also help educators and lay people, “think about suicide in the youth population in ways we don’t normally think about it,” Dr. Lewis said.

Covariates considered for profiles were determined through expert consensus between pediatric psychiatrists, general pediatricians, pediatric hospitalists, pediatric complex care physicians, and pediatric pharmacoepidemiologists.

Age was broken into three groups: 5-9 years, 10-13 years, and 14-17 years based on Centers for Disease Control and Prevention reporting and previous studies that showed significant increases in suicide rates in these age-based subgroups.
 

Results are preliminary

The authors note that the profiles were developed using data from 1,000 children with neuropsychiatric complaints at two academic children’s hospitals and are thus preliminary.

“Future studies should focus on validating these risk profiles in a larger, more heterogeneous population of children and adolescents,” the authors write.

They also acknowledge that they were not able to include factors such as medication use, previous suicidal behavior, and family and social support, which also factor into risk.

The study authors and Dr. Lewis report no relevant financial relationships.

BOSTON – The investigational drug donanemab yielded greater amyloid clearance and amyloid plaque reduction than aducanumab in early, symptomatic Alzheimer’s disease, according to the results of a head-to-head study.

Nearly 40% of patients treated with donanemab had amyloid clearance at 6 months compared with less than 2% of those who received aducanumab, which was approved in 2021 amid a great deal of controversy.

Titration for donanemab progressed more quickly, with participants receiving a maximum dose twice as early as those on aducanumab, without any increase in rates of amyloid-related imaging abnormalities (ARIA) – the most common side effect of amyloid drugs.

Early results from the randomized phase 3 TRAILBLAZER-ALZ 4 trial of donanemab come just 3 months after the Food and Drug Administration denied manufacturer Eli Lilly’s request for accelerated approval for the drug.

“This study shows that the drug with the quicker titration scheme, donanemab, produced more amyloid lowering and did it without having more ARIA,” said lead investigator Stephen P. Salloway, MD, director of the Memory and Aging Program at Butler Hospital in Providence, R.I., and a professor of neurology at Brown University.

The findings were presented at the 2023 annual meeting of the American Academy of Neurology.
 

Multicenter, head-to-head trial

Donanemab received breakthrough therapy designation in 2021. The drug works similarly to aducanumab and lecanemab, which was approved earlier this year. All three bind to different parts of the amyloid molecule and stimulate an immune response to help clear amyloid plaques, although they each have a distinctive binding component.

TRAILBLAZER-ALZ 4 was conducted at 31 sites across the United States, enrolling 140 patients aged 50-85 years with early and symptomatic Alzheimer’s disease. Study participants received donanemab or aducanumab at escalating doses for 18 months.

Donanemab was titrated more quickly, with participants receiving 700 mg via IV infusion once a month for 3 months before reaching the maximum dose of 1,400 mg in the fourth month of the study.

Aducanumab titration was slower, beginning at 1 mg/kg via IV monthly for 2 months, then 3 mg/kg for another 2 months, and 6 mg/kg for 2 more months before reaching the maximum dose of 10 mg/kg in the seventh month.

After 6 months of treatment, PET scan analysis revealed that 37.9% of donanemab-treated patients achieved amyloid clearance compared with just 1.6% of those who received aducanumab (P < .001).

Among patients with intermediate tau levels (n = 27 for donanemab and n = 28 for aducanumab), 38.5% of those who received donanemab achieved amyloid clearance compared with 3.8% of patients in the aducanumab group (P = .008).

Amyloid levels were 65.2% lower in donanemab patients, while levels in those receiving aducanumab were reduced by 17.0% (P < .001). Among those with intermediate tau, amyloid levels decreased with donanemab by 63.9% and 25.4% with aducanumab (P ≤ .001).

Investigators also noted a greater reduction in plasma ptau217 with donanemab.

Adverse events were similar between groups, with 62.0% of the donanemab group and 66.7% of aducanumab-treated participants reporting an adverse event.

There were no serious adverse events due to ARIA with donanemab, but one participant in the aducanumab group had a serious adverse event linked to ARIA.

“Even though the amyloid lowering was greater with donanemab, the rate of ARIA was similar, which suggests that the speed and depth of amyloid removal is not driving ARIA,” Dr. Salloway said.

There are three other Trailblazer trials of donanemab. Unlike in similar trials, participants in all three of these studies who received the trial drug could discontinue treatment once criteria for amyloid clearance were met.

That’s precisely what happened with Trailblazer 2, the study on which Lilly based its request for accelerated approval. Ironically, that trial design also contributed to the FDA’s decision to reject that request.

The FDA required data from at least 100 patients who had received donanemab for a minimum of 1 year. While the trial included more than 100 patients, many patients discontinued treatment early after achieving the targeted amount of amyloid clearance.

“They had success, and they got punished for it, in my opinion,” Dr. Salloway said.

Final data from Trailblazer 2 is due in the next month, and if results are positive, Lilly is expected to file for full approval.
 

Questions remain

“This is an interesting study that suggests donanemab may remove amyloid faster in more people than aducanumab,” said Heather Snyder, PhD, Alzheimer’s Association vice president of medical and scientific relations, who commented on the findings.

Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, also commented on the findings. He noted that faster amyloid clearance “means less time for requiring sometimes burdensome and expensive infusions.”

Both Dr. Snyder and Dr. Fillit noted that longer-term results are needed, along with studies of whether amyloid clearance offers a protective benefit against Alzheimer’s dementia. More results from Trailblazer 4 will be reported after 12 months and again at 18 months.

“There are obviously still a lot of questions about these drugs and whether reducing amyloid plaque will actually preserve cognitive function or at least slow decline,” Dr. Fillit said.

It will also be important to understand the timing of treatment, including when anti-amyloid therapies should be administered and for how long.

“It will be important to understand how these results translate to patient care and treatment plans, should this drug receive FDA approval,” Dr. Snyder said. “Patients should have the opportunity to make a decision, alongside their physician, on a treatment path that is right for them.”

The study was funded by Eli Lilly. Dr. Salloway has been a consultant for Biogen, EISAI, Lilly, Genentech, Novo Nordisk, Prothena, and others. Dr. Snyder and Dr. Fillit have disclosed no relevant financial relationships.

BOSTON – The investigational drug donanemab yielded greater amyloid clearance and amyloid plaque reduction than aducanumab in early, symptomatic Alzheimer’s disease, according to the results of a head-to-head study.

Nearly 40% of patients treated with donanemab had amyloid clearance at 6 months compared with less than 2% of those who received aducanumab, which was approved in 2021 amid a great deal of controversy.

Titration for donanemab progressed more quickly, with participants receiving a maximum dose twice as early as those on aducanumab, without any increase in rates of amyloid-related imaging abnormalities (ARIA) – the most common side effect of amyloid drugs.

Early results from the randomized phase 3 TRAILBLAZER-ALZ 4 trial of donanemab come just 3 months after the Food and Drug Administration denied manufacturer Eli Lilly’s request for accelerated approval for the drug.

WASHINGTON – A novel program for parents of highly dependent adult children reduces parental burden and anxiety in their offspring, a new pilot study shows.

Known as failure to launch (FTL) syndrome, the criteria for this condition include the absence of a neurodevelopmental, mental, or intellectual condition, difficulty adapting to the challenges of adulthood, and living with or at the expense of parents.

Results suggest that the program benefits families dealing with FTL, said study investigator Uri Berger, PhD, postdoctoral associate, Yale Child Study Center Anxiety and Mood Disorders Program, New Haven, Conn.

“If you encounter parents who are say 50-60 years old who have a child with FTL, you can tell them there’s something they can do; there’s work they can do even if their child is refusing to go to therapy,” he said.

The findings were presented as part of the Anxiety and Depression Association of America Anxiety & Depression conference.
 

Anxious, isolated

Estimates suggest that there are 3.3 million physically able adults with FTL and that the disorder may be on the rise. These individuals often present with mental health symptoms including anxiety, depression, and suicidality, and tend to be socially isolated.

The investigators noted that intervening is often challenging because individuals with the syndrome are frequently noncompliant with therapy, and currently there is no standard of care.

“The longer you’re isolated, the harder it is getting out of your cocoon, and when these adult children get to the point where they seek help, they’re less likely to comply,” he said. However, he noted, this is not because they are lazy; it’s that they’re “very, very anxious.”

Parents and other family members are also negatively affected. Dr. Berger noted that 15% of parents of a child with FTL equate their caregiver burden with having a family member with a chronic physical illness. “It’s huge; parents go through hell and it’s very hard on them. Many believe it is their fault and they feel a lot of shame.”

Supportive Parenting for Anxious Childhood Emotions (SPACE) is a manualized, parent-based program for childhood anxiety and obsessive-compulsive disorder. It has been tested in clinical trials and found to be noninferior to cognitive behavioral therapy for childhood anxiety.

The research adapted it to treat FTL. SPACE-FTL focuses on reducing parents’ family accommodation (FA), a descriptor for a child’s excessive dependence on their parents to help them avoid anxiety-provoking situations.

The study examined the feasibility, acceptability, and treatment satisfaction and its effect on adult child psychopathology symptoms, parents’ FA, and the paternal burden of caring for adult children.

The study included parents (mean age, 59.46 years; 85% female) of 40 adult children with FTL (mean age, 23.51 years; 20% female) from across the United States.

Parents were randomized to a 13-week wait-list or the SPACE-FTL program, which involves 13-20 therapy sessions, depending on the need. The average number of sessions in the study was 15. The program has five key components:

• Providing information emphasizing FTL as not a character flaw but a problem with anxiety.
• Helping parents identify how they accommodate their child’s behavior, and facilitating an environment that encourages independence.
• Getting parents to show acceptance and confidence in their child who’s trying to overcome anxiety when, for example, they seek employment, instead of being overprotective and demanding.
• Focusing on change nonconfrontationally.
• Involving other family, community members, and professionals who can support the parent, child, or both.

The recruitment, treatment sessions, and assessments were all done online. Most participants rated the intervention as highly satisfactory on the Client Satisfaction Questionnaire (CSQ-8; mean score, 27.7 out of a maximum of 32). About 60% of the offspring no longer met full criteria for FTL (P < .001; Cohen’s D = 1.76).

All children of the wait-listed parents still met criteria for FTL.

FTL symptoms decreased significantly in the offspring of the intervention group, as seen in both in the Adult Entitled Dependence Scale (AED; P < .05; Cohen’s D = 0.84); and the Adaptive Behaviors Scale (ABS; P < .05; Cohen’s D = 0.70).

There was no change in anxiety as assessed by the Adult Behavior Checklist (ABCL). But Dr. Berger noted that child anxiety is difficult to assess through parental report.

“This population is self-isolating and parents sometimes don’t know what’s going on,” and ABCL measures may not be “as sensitive as we would have liked them to be,” Dr. Berger said.

Parental burden was significantly decreased as measured by the Zarit Burden Interview (ZBI; P < .05; Cohen’s D = 0.70). In addition, family accommodation decreased significantly as determined by the Family Accommodation Scale–Anxiety (FASA; P < .05; Cohen’s D = 0.70).
 

Innovative work

In a comment, Jonathan E. Alpert, MD, PhD, chair, department of psychiatry and behavioral sciences, and professor of psychiatry, neuroscience, and pediatrics, Albert Einstein College of Medicine, New York, described the program as “innovative.”

He noted that the SPACE-FTL approach provides parents with education and skills to reduce behaviors that reinforce their child’s avoidance of independent activities. Such behaviors “may inadvertently contribute to the adult child remaining stuck,” he said.

“Through its involvement of parents and use of a structured approach, SPACE-FTL is a very interesting step toward more evidence-based therapies.”

However, he noted that the number of study participants is still “very low” and further work is needed to better characterize this condition and develop effective therapies.

He noted that parents of adult children with FTL should not be judged or blamed. “They have been living with a worrisome problem for years and are simply doing their best to cope as any of us would do.”

In addition, he noted that some adult children aren’t capable of launching because of a serious mental illness or substance use disorder that needs treatment.

It’s unclear just how many adult children have FTL, as the condition lacks formal, agreed-upon clinical and research criteria and a reliable evidence base for treatment, Dr. Alpert said.

“Whatever the actual numbers of FTL, my anecdotal clinical experience suggests that it is a very common problem which is understudied.”

He added that the definitions of FTL should include cultural context. In some groups, it’s quite normal for adults in their 20s, 30s, or even older to live with their parents, Dr. Alpert said.

Dr. Berger and Dr. Albert report no relevant financial relationships.

About 60% of the offspring no longer met full criteria for FTL (P < .001; Cohen’s D = 1.76).

All children of the wait-listed parents still met criteria for FTL.

FTL symptoms decreased significantly in the offspring of the intervention group, as seen in both in the Adult Entitled Dependence Scale (AED; P < .05; Cohen’s D = 0.84); and the Adaptive Behaviors Scale (ABS; P < .05; Cohen’s D = 0.70).

There was no change in anxiety as assessed by the Adult Behavior Checklist (ABCL). But Dr. Berger noted that child anxiety is difficult to assess through parental report.

“This population is self-isolating and parents sometimes don’t know what’s going on,” and ABCL measures may not be “as sensitive as we would have liked them to be,” Dr. Berger said.

Parental burden was significantly decreased as measured by the Zarit Burden Interview (ZBI; P < .05; Cohen’s D = 0.70). In addition, family accommodation decreased significantly as determined by the Family Accommodation Scale–Anxiety (FASA; P < .05; Cohen’s D = 0.70).
 

Innovative work

In a comment, Jonathan E. Alpert, MD, PhD, chair, department of psychiatry and behavioral sciences, and professor of psychiatry, neuroscience, and pediatrics, Albert Einstein College of Medicine, New York, described the program as “innovative.”

He noted that the SPACE-FTL approach provides parents with education and skills to reduce behaviors that reinforce their child’s avoidance of independent activities. Such behaviors “may inadvertently contribute to the adult child remaining stuck,” he said.

“Through its involvement of parents and use of a structured approach, SPACE-FTL is a very interesting step toward more evidence-based therapies.”

However, he noted that the number of study participants is still “very low” and further work is needed to better characterize this condition and develop effective therapies.

He noted that parents of adult children with FTL should not be judged or blamed. “They have been living with a worrisome problem for years and are simply doing their best to cope as any of us would do.”

In addition, he noted that some adult children aren’t capable of launching because of a serious mental illness or substance use disorder that needs treatment.

It’s unclear just how many adult children have FTL, as the condition lacks formal, agreed-upon clinical and research criteria and a reliable evidence base for treatment, Dr. Alpert said.

“Whatever the actual numbers of FTL, my anecdotal clinical experience suggests that it is a very common problem which is understudied.”

He added that the definitions of FTL should include cultural context. In some groups, it’s quite normal for adults in their 20s, 30s, or even older to live with their parents, Dr. Alpert said.

Dr. Berger and Dr. Albert report no relevant financial relationships.

Advances in the understanding of neurobiological and neuro­psychiatric pathophysiology have opened new avenues of treatment for psychiatric patients. Historically, with a few exceptions, most psychiatric medications have been administered orally. However, many of the newer treatments require some form of specialized administration because they cannot be taken orally due to their chemical property (such as aducanumab); because there is the need to produce stable blood levels of the medication (such as brexanolone); because oral administration greatly diminished efficacy (such as oral vs IV magnesium or scopolamine), or because the treatment is focused on specific brain structures. This need for specialized administration has created a subspecialty called interventional psychiatry.

Part 1 of this 2-part article provides an overview of 1 type of interventional psychiatry: parenterally administered medications, including those administered via IV. We also describe 3 other interventional approaches to treatment: stellate ganglion blocks, glabellar botulinum toxin (BT) injections, and trigger point injections. In Part 2 we will review interventional approaches that involve neuromodulation.

Parenteral medications in psychiatry

In general, IV and IM medications can be more potent that oral medications due to their overall faster onset of action and higher blood concentrations. These more invasive forms of administration can have significant limitations, such as a risk of infection at the injection site, the need to be administered in a medical setting, additional time, and patient discomfort.

Table 1 lists short-acting injectable medications used in psychiatry, and Table 2 lists long-acting injectable medications. Parenteral administration of antipsychotics is performed to alleviate acute agitation or for chronic symptom control. These medications generally are not considered interventional treatments, but could be classified as such due to their invasive nature.¹ Furthermore, inhalable loxapine—which is indicated for managing acute agitation—requires a Risk Evaluation and Mitigation Strategy program consisting of 2 hours observation and monitoring of respiratory status.^2,3 Other indications for parenteral treatments include IM naltrexone extended release⁴ and subcutaneous injections of buprenorphine extended release⁵ and risperidone.⁶

IV administration

Most IV treatments described in this article are not FDA-approved for psychiatric treatment. Despite this, many interventional psychiatric treatments are part of clinical practice. IV infusion of ketamine is the most widely known and most researched of these. Table 3 lists other IV treatments that could be used as psychiatric treatment.

Ketamine

Since the early 1960s, ketamine has been used as a surgical anesthetic for animals. In the United States, it was approved for human surgical anesthesia in 1970. It was widely used during the Vietnam War due to its lack of inhibition of respiratory drive; medical staff first noticed an improvement in depressive symptoms and the resolution of suicidal ideation in patients who received ketamine. This led to further research on ketamine, particularly to determine its application in treatment-resistant depression (TRD) and other conditions.⁷ IV ketamine administration is most widely researched, but IM injections, intranasal sprays, and lozenges are also available. The dissociative properties of ketamine have led to its recreational use.⁸

Hypotheses for the mechanism of action of ketamine as an antidepressant include direct synaptic or extrasynaptic (GluN2B-selective), N-methyl-D-aspartate receptor (NMDAR) inhibition, selectively greater inhibition of NMDARs localized on GABAergic (gamma-aminobutyric acid) interneurons, and the role of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor activation. There are links between ketamine’s antidepressant actions and downstream mechanisms regulating synaptic plasticity, including brain-derived neurotrophic factor, eukaryotic elongation factor 2, mammalian target of rapamycin, and glycogen synthase kinase-3. Multiple other ketamine-associated mechanisms also have been described.^9,10 Action on the mu-opioid receptor is also known, possibly contributing to both antidepressant and anesthetic properties of ketamine.¹¹ Rapid onset of ketamine antidepressant action is especially valuable.¹²

Continue to: Ketamine is a schedule...

Ketamine is a schedule III medication with addictive properties. Delirium, panic attacks, hallucinations, nightmares, dysphoria, and paranoia may occur during and after use.¹³ Premedication with benzodiazepines, most notably lorazepam, is occasionally used to minimize ketamine’s adverse effects, but this generally is not recommended because doing so reduces ketamine’s antidepressant effects.¹⁴ Driving and operating heavy machinery is contraindicated after IV infusion. The usual protocol involves an IV infusion of ketamine 0.4 mg/kg to 1 mg/kg dosing over 1 hour. Doses between 0.4 mg/kg and 0.6 mg/kg are most common. Ketamine has a therapeutic window; doses >0.5 mg/kg are progressively less effective.¹⁵ Unlike the recommendation after esketamine administration, after receiving ketamine, patients remain in the care of their treatment team for <2 hours.

Esketamine, the S enantiomer of ketamine, was FDA-approved for TRD as an intranasal formulation. Esketamine is more commonly used than IV ketamine because it is FDA-approved and typically covered by insurance, but it may not be as effective.¹⁶ An economic analysis by Brendle et al¹⁷ suggested insurance companies would lower costs if they covered ketamine infusions vs intranasal esketamine.

Aducanumab and lecanemab

The most recent FDA-approved interventional agents are aducanumab and lecanemab, which are indicated for treating Alzheimer disease.^18,19 Both are human monoclonal antibodies that bind selectively and with high affinity to amyloid beta plaque aggregates and promote their removal by Fc receptor–mediated phagocytosis.²⁰

FDA approval of aducanumab and lecanemab was controversial. Initially, aducanumab’s safety monitoring board performed a futility analysis that suggested aducanumab was unlikely to separate from placebo, and the research was stopped.²¹ The manufacturer petitioned the FDA to consider the medication for accelerated approval on the basis of biomarker data showing that amyloid beta plaque aggregates become smaller. Current FDA approval is temporary to allow patients access to this potentially beneficial agent, but the manufacturer must supply clinical evidence that the reduction of amyloid beta plaques is associated with desirable changes in the course of Alzheimer disease, or risk losing the approval.

Lecanemab is also a human monoclonal antibody intended to remove amyloid beta plaques that was FDA-approved under the accelerated approval pathway.²² Unlike aducanumab, lecanemab demonstrated a statistically significant (although clinically imperceptible) reduction in the rate of cognitive decline; it did not show cognitive improvement.²³ Lecanemab also significantly reduced amyloid beta plaques.²³

Continue to: Aducanumab and lecanemab are generally...

Aducanumab and lecanemab are generally not covered by insurance and typically cost >$26,000 annually. Both are administered by IV infusion once a month. More monoclonal antibody medications for treating early Alzheimer disease are in the late stages of development, most notably donanebab.²⁴ Observations during clinical trials found that in the later stages of Alzheimer disease, forceful removal of plaques by the autoimmune process damages neurons, while in less dense deposits of early dementia such removal is not harmful to the cells and prevents amyloid buildup.

Brexanolone

Brexanolone is an aqueous formulation of allopregnanolone, a major metabolite of progesterone and a positive allosteric modulator of GABA-A receptors.²⁵ Its levels are maximal at the end of the third trimester of pregnancy and fall rapidly following delivery. Research showed a 3-day infusion was rapidly and significantly effective for treating postpartum depression²⁶ and brexanolone received FDA approval for this indication in March 2019.²⁷ However, various administrative, economic, insurance, and other hurdles make it difficult for patients to access this treatment. Despite its rapid onset of action (usually 48 hours), brexanolone takes an average of 15 days to go through the prior authorization process.²⁸ In addition to the need for prior authorization, the main impediment to the use of brexanolone is the 3-day infusion schedule, which greatly magnifies the cost but is partially circumvented by the availability of dedicated outpatient centers.

Magnesium

Magnesium is on the World Health Organization’s Model List of Essential Medicines.²⁹ There has been extensive research on the use of magnesium sulfate for psychiatric indications, especially for depression.³⁰ Magnesium functions similarly to calcium channel blockers by competitively blocking intracellular calcium channels, decreasing calcium availability, and inhibiting smooth muscle contractility.³¹ It also competes with calcium at the motor end plate, reducing excitation by inhibiting the release of acetylcholine.³² This property is used for high-dose IV magnesium treatment of impending preterm labor in obstetrics. Magnesium sulfate is the drug of choice in treating eclamptic seizures and preventing seizures in severe preeclampsia or gestational hypertension with severe features.³³ It is also used to treat torsade de pointes, severe asthma exacerbations, constipation, and barium poisoning.³⁴ Beneficial use in asthma treatment³⁵ and the treatment of migraine³⁶ have also been reported.

IV magnesium in myocardial infarction may be harmful,³⁷ though outside of acute cardiac events, magnesium is found to be safe.³⁸

Oral magnesium sulfate is a common over-the-counter anxiety remedy. As a general cell stabilizer (mediated by the reduction of intracellular calcium), magnesium is potentially beneficial outside of its muscle-relaxing properties, although muscle relaxing can benefit anxious patients. It is used to treat anxiety,³⁹ alcohol withdrawal,⁴⁰ and fear.⁴¹ Low magnesium blood levels are found in patients with depression, schizophrenia,⁴² and attention-deficit/hyperactivity disorder.⁴³ However, it is important to note that the therapeutic effect of magnesium when treating anxiety and headache is independent of preinfusion magnesium blood levels.⁴³

Continue to: The efficacy of oral magnesium...

The efficacy of oral magnesium is not robust. However, IV administration has a pronounced beneficial effect as an abortive and preventative treatment in many patients with anxiety.⁴⁴

IV administration of magnesium can produce adverse effects, including flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, and cardiac and CNS depression. These complications are very rare and dose-dependent.⁴⁵ Magnesium is excreted by the kidneys, and dosing must be decreased in patients with kidney failure. The most common adverse effect is local burning along the vein upon infusion; small doses of IV lidocaine can remedy this. Hot flashes are also common.⁴⁵

Various dosing strategies are available. In patients with anxiety, application dosing is based on the recommended preeclampsia IV dose of 4 g diluted in 250 mL of 5% dextrose. Much higher doses may be used in obstetrics. Unlike in obstetrics, for psychiatric indications, magnesium is administered over 60 to 90 minutes. Heart monitoring is recommended.

Scopolamine

Scopolamine is primarily used to relieve nausea, vomiting, and dizziness associated with motion sickness and recovery from anesthesia. It is also used in ophthalmology and in patients with excessive sweating. In off-label and experimental applications, scopolamine has been used in patients with TRD.⁴⁶

Scopolamine is an anticholinergic medication. It is a nonselective antagonist at muscarinic receptors.⁴⁷ Tricyclic antidepressants (TCAs) possess strong anticholinergic function. Newer generations of antidepressants were designed specifically not to have this function because it was believed to be an unwanted and potentially dangerous adverse effect. However, data suggest that anticholinergic action is important in decreasing depressive symptoms. Several hypotheses of anticholinergic effects on depression have been published since the 1970s. They include the cholinergic-adrenergic hypothesis,⁴⁸ acetylcholine predominance relative to adrenergic action hypothesis,⁴⁹ and insecticide poisoning observations.⁵⁰ Centrally acting physostigmine (but not peripherally acting neostigmine) was reported to control mania.^48,51 A genetic connection between the M2acetylcholine receptor in patients with major depressive disorder (MDD) and alcohol use disorder is also suggestive.⁵²

Continue to: Multiple animal studies show...

Multiple animal studies show direct improvement in mobility and a decrease in despair upon introducing anticholinergic substances.^53-55 The cholinergic theory of depression has been studied in several controlled clinical human studies.^56,57 Use of a short-acting anticholinergic glycopyrrolate during electroconvulsive therapy (ECT) may contribute to the procedure’s efficacy.

Human research shows scopolamine has a higher efficacy as an antidepressant and anti-anxiety medication in women than in men,⁵⁸ possibly because estrogen increases the activity of choline acetyltransferase and release of acetylcholine.^59,60 M2receptors mediate estrogen influence on the NMDAR, which may explain the anticholinergic effects of depression treatments in women.⁶¹

Another proposed mechanism of action of scopolamine is a potent inhibition of the NMDAR.⁶² Rapid treatments of depression may be based on this mechanism. Examples of such treatments include IV ketamine and sleep deprivation.⁶³ IV scopolamine shows potency in treating MDD and bipolar depression. This treatment should be reserved for patients who do not respond to or are not candidates for other usual treatment modalities of MDD and for the most severe cases. Scopolamine is 30 times more potent than amitriptyline in anticholinergic effect and reportedly produces sustained improvement in MDD.⁶⁴

Scopolamine has no black-box warnings. It has not been studied in pregnant women and is not recommended for use during pregnancy. Due to possible negative cardiovascular effects, a normal electrocardiogram is required before the start of treatment. Exercise caution in patients with glaucoma, benign prostatic enlargement, gastroparesis, unstable cardiovascular status, or severe renal impairment.

Treatment with scopolamine is not indicated for patients with myasthenia gravis, psychosis, or seizures. Patients must be off potassium for 3 days before beginning scopolamine treatment. Patients should consult with their cardiologist before having a scopolamine infusion. Adverse reactions may include psychosis, tachycardia, seizures, paralytic ileus, and glaucoma exacerbation. The most common adverse effects of scopolamine infusion treatment include drowsiness, dry mouth, blurred vision, lightheadedness, and dizziness. Due to possible drowsiness, operating motor vehicles or heavy machinery must be avoided on the day of treatment.⁶⁵ Overall, the adverse effects of scopolamine are preventable and manageable, and its antidepressant efficacy is noteworthy.⁶⁶

Continue to: Treatment typically consists of 3 consecutive infusions...

Treatment typically consists of 3 consecutive infusions of 4 mcg/kg separated by 3 to 5 days.⁵⁶ It is possible to have a longer treatment course if the patient experiences only partial improvement. Repeated courses or maintenance treatment (similar to ECT maintenance) are utilized in some patients if indicated. Cardiac monitoring is mandatory.

Clomipramine

Clomipramine, a TCA, acts as a preferential inhibitor of 5-hydroxytryptamine uptake and has proven effective in managing depression, TRD, and obsessive-compulsive disorder (OCD).⁶⁷ Although this medication has reported treatment benefits for patients with phobia, panic disorder,¹⁵ chronic pain,⁶⁸ Tourette syndrome,⁶⁹ premature ejaculation, anorexia nervosa,⁷⁰ cataplexy,⁴⁹ and enuresis,⁷¹ it is FDA-approved only for the treatment of OCD.⁷² Clomipramine may also be beneficial for pain and headache, possibly because of its anti-inflammatory action.⁷³ The anticholinergic effects of clomipramine may add to its efficacy in depression.

The pathophysiology of MDD is connected to hyperactivity of the HPA axis and elevated cortisol levels. Higher clomipramine plasma levels show a linear correlation with lower cortisol secretion and levels, possibly aiding in the treatment of MDD and anxiety.⁷⁴ The higher the blood level, the more pronounced clomipramine’s therapeutic effect across multiple domains.⁷⁵

IV infusion of clomipramine produces the highest concentration in the shortest time, but overall, research does not necessarily support increased efficacy of IV over oral administration. There is evidence suggesting that subgroups of patients with severe, treatment-refractory OCD may benefit from IV agents and research suggests a faster onset of action.⁷⁶ Faster onset of symptom relief is the basis for IV clomipramine use. In patients with OCD, it can take several months for oral medications to produce therapeutic benefits; not all patients can tolerate this. In such scenarios, IV administration may be considered, though it is not appropriate for routine use until more research is available. Patients with treatment-resistant OCD who have exhausted other means of symptom relief may also be candidates for IV treatment.

The adverse effects of IV clomipramine are no different from oral use, though they may be more pronounced. A pretreatment cardiac exam is desirable because clomipramine, like other TCAs, may be cardiotoxic. The anticholinergic adverse effects of TCAs are well known to clinicians⁷⁷ and partially explained in the scopolamine section of this article. It is not advisable to combine clomipramine with other TCAs or serotonin reuptake inhibitors. Clomipramine also should not be combined with monoamine oxidase inhibitors, though such a combination was reported in medical literature.⁷⁸ Combination with antiarrhythmics such as lidocaine or opioids such as fentanyl or and tramadol is highly discouraged (fentanyl and tramadol also have serotonergic effects).⁷⁹

Continue to: Clomipramine for IV use is not commercially available...

Clomipramine for IV use is not commercially available and must be sterilely compounded. The usual course of treatment is a series of 3 infusions: 150 mg on Day 1, 200 mg on Day 2 or Day 3, and 250 mg on Day 3, Day 4, or Day 5, depending on tolerability. A protocol with a 50 mg/d starting dose and titration up to a maximum dose of 225 mg/d over 5 to 7 days has been suggested for inpatient settings.⁶⁷ Titration to 250 mg is more common.⁸⁰

A longer series may be performed, but this increases the likelihood of adverse effects. Booster and maintenance treatments are also completed when required. Cardiac monitoring is mandatory.

Vortioxetine and citalopram

IV treatment of depression with vortioxetine and citalopram has been explored but has not yet taken hold in clinical psychiatry.^81,82

Injections and blocks

Three interventional approaches to treatment that possess psychotherapeutic potential include stellate ganglion blocks (SGBs), glabellar BT injections, and trigger point injections (TPIs). None of these are FDA-approved for psychiatric treatment.

Stellate ganglion blocks

The sympathetic nervous system is involved in autonomic hyperarousal and is at the core of posttraumatic symptomatology.⁸³ Insomnia, anxiety, irritability, hypervigilance, and other excitatory CNS events are connected to the sympathetic nervous system and amygdala activation is commonly observed in those exposed to extreme stress or traumatic events.⁸⁴

Continue to: SGBs were first performed 100 years ago...

SGBs were first performed 100 years ago and reported to have beneficial psychiatric effects at the end of the 1940s. In 1998 in Finland, improvement of posttraumatic stress disorder (PTSD) symptoms was observed accidentally via thoracic level spine blocks.⁸⁵ In 2006, cervical level sympathetic blocks were shown to be effective for PTSD symptom control.⁸⁶ By the end of 2010, Veterans Administration hospitals adopted SGBs to treat veterans with PTSD.^87,88 The first multisite, randomized clinical trial of SGB for PTSD confirmed multiple previous reports of treatment efficacy. Specifically, 2 SGB treatments 2 weeks apart effectively reduced total symptom severity scores over 8 weeks.⁸⁷

Since the stellate ganglion is connected to the amygdala, SGB has also been assessed for treating anxiety and depression.^89,90 Outside of PTSD, SGBs are used to treat complex regional pain syndrome,⁹¹ phantom limb pain, trigeminal neuralgia,⁹² intractable angina,⁹³ and postherpetic neuralgia in the head, neck, upper chest, or arms.⁹⁴ The procedure consists of an injection of a local anesthetic through a 25-gauge needle into the stellate sympathetic ganglion at the C6 or C7 vertebral levels. An injection into C6 is considered safer because of specific cervical spine anatomy. Ideally, fluoroscopic guidance or ultrasound is used to guide needle insertion.⁹⁵

A severe drop in blood pressure may be associated with SGBs and is mitigated by IV hydration. Other adverse effects include red eyes, drooping of the eyelids, nasal congestion, hoarseness, difficulty swallowing, a sensation of a “lump” in the throat, and a sensation of warmth or tingling in the arm or hand. Bilateral SGB is contraindicated due to the danger of respiratory arrest.⁹⁶

Glabellar BT injections

OnabotulinumtoxinA (BT) injection was first approved for therapeutic use in 1989 for eye muscle disorders such as strabismus⁹⁷ and blepharospasm.⁹⁸ It was later approved for several other indications, including cosmetic use, hyperhidrosis, migraine prevention, neurogenic bladder disorder, overactive bladder, urinary incontinence, and spasticity.^99-104 BT is used off-label for achalasia and sialorrhea.^105,106 Its mechanism of action is primarily attributed to muscle paralysis by blocking presynaptic acetylcholine release into neuromuscular junctions.¹⁰⁷

Facial BT injections are usually administered for cosmetic purposes, but smoothing forehead wrinkles and frown lines (the glabellar region of the face) both have antidepressant effects.¹⁰⁸ BT injections into the glabellar region also demonstrate antidepressant effects, particularly in patients with comorbid migraines and MDD.¹⁰⁹ Early case observations supported the independent benefit of the toxin on MDD when the toxin was injected into the glabellar region.^110,111 The most frequent protocol involves injections in the procerus and corrugator muscles.

Continue to: The facial feedback/emotional proprioception hypothesis...

The facial feedback/emotional proprioception hypothesis has dominated thinking about the mood-improving effects of BT. The theory is that blocking muscular expression of sadness (especially in the face) interrupts the experience of sadness; therefore, depression subsides.^112,113 However, BT injections in the muscles involved in the smile and an expression of positive emotions (lateral part of the musculus orbicularis oculi) have been associated with increased MDD scores.¹¹⁴ Thus, the mechanism clearly involves more than the cosmetic effect, since facial muscle injections in rats also have antidepressant effects.¹¹⁵

The use of progressive muscle relaxation is well-established in psychiatric treatment. The investigated conditions of increased muscle tone, especially torticollis and blepharospasm, are associated with MDD, and it may be speculated that proprioceptive feedback from the affected muscles may be causally involved in this association.^116-118 Activity of the corrugator muscle has been positively associated with increased amygdala activity.¹¹⁹ This suggests a potential similar mechanism to that hypothesized for SGB.

Alternatively, BT is commonly used to treat chronic conditions that may contribute to depression; its success in relieving the underlying problem may indirectly relieve MDD. Thus, in a postmarketing safety evaluation of BT, MDD was demonstrated 40% to 88% less often by patients treated with BT for 6 of the 8 conditions and injection sites, such as in spasms and spasticity of arms and legs, torticollis and neck pain, and axilla and palm injections for hyperhidrosis. In a parotid and submandibular glands BT injection subcohort, no patients experienced depressive symptoms.¹²⁰

Medicinal BT is generally considered safe. The most common adverse effects are hypersensitivity, injection site reactions, and other adverse effects specific to the injection site.¹²¹ Additionally, the cosmetic effects are transient, given the nature of the medication.

Trigger point injections

TPIs in the neck and shoulders are frequently used to treat tension headaches and various referred pain locations in the face and arms. Tension and depression frequently overlap in clinical practice.¹²² Relieving muscle tension (with resulting trigger points) improves muscle function and mood.

Continue to: The higher the number of active...

The higher the number of active trigger points (TPs), the greater the physical burden of headache and the higher the anxiety level. Gender differences in TP prevalence and TPI efficacy have been described in the literature. For example, the number of active TPs seems directly associated with anxiety levels in women but not in men.¹²³ Although TPs appear to be more closely associated with anxiety than depression,¹²⁴ depression associated with muscle tension does improve with TPIs. European studies have demonstrated a decrease in scores on the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale following TPI treatment.¹²⁵ The effect may be indirect, as when a patient’s pain is relieved, sleep and other psychiatric symptoms improve.¹²⁶

A randomized controlled trial by Castro Sánchez et al¹²⁷ demonstrated that dry needling therapy in patients with fibromyalgia syndrome (FMS) showed improvements in pain pressure thresholds, body pain, vitality, and social function, as well as total FMS symptoms, quality of sleep, anxiety, hospital anxiety and depression, general pain intensity, and fatigue.

Myofascial pain syndrome, catastrophizing, and muscle tension are common in patients with depression, anxiety, and somatization. Local TPI therapy aimed at inactivating pain generators is supported by moderate quality evidence. All manner of therapies have been described, including injection of saline, corticosteroids, local anesthetic agents, and dry needling. BT injections in chronic TPs are also practiced, though no specific injection therapy has been reliably shown to be more advantageous than another. The benefits of TPIs may be derived from the needle itself rather than from any specific substance injected. Stimulation of a local twitch response with direct needling of the TP appears of importance. There is no established consensus regarding the number of injection points, frequency of administration, and volume or type of injectate.¹²⁸

Adverse effects of TPIs relate to the nature of the invasive therapy, with the risk of tissue damage and bleeding. Pneumothorax risk is present with needle insertion at the neck and thorax.¹²⁹ Patients with diabetes may experience variations in blood sugar control if steroids are used.

Bottom Line

Interventional treatment modalities that may have a role in psychiatric treatment include IV administration of ketamine, aducanumab, lecanemab, brexanolone, magnesium, scopolamine, and clomipramine. Other interventional approaches include stellate ganglion blocks, glabellar botulinum toxin injections, and trigger point injections.

Most IV treatments described in this article are not FDA-approved for psychiatric treatment. Despite this, many interventional psychiatric treatments are part of clinical practice. IV infusion of ketamine is the most widely known and most researched of these. Table 3 lists other IV treatments that could be used as psychiatric treatment.

Ketamine

Since the early 1960s, ketamine has been used as a surgical anesthetic for animals. In the United States, it was approved for human surgical anesthesia in 1970. It was widely used during the Vietnam War due to its lack of inhibition of respiratory drive; medical staff first noticed an improvement in depressive symptoms and the resolution of suicidal ideation in patients who received ketamine.

Delirium, panic attacks, hallucinations, nightmares, dysphoria, and paranoia may occur during and after use.¹³ Premedication with benzodiazepines, most notably lorazepam, is occasionally used to minimize ketamine’s adverse effects, but this generally is not recommended because doing so reduces ketamine’s antidepressant effects.¹⁴ Driving and operating heavy machinery is contraindicated after IV infusion. The usual protocol involves an IV infusion of ketamine 0.4 mg/kg to 1 mg/kg dosing over 1 hour. Doses between 0.4 mg/kg and 0.6 mg/kg are most common. Ketamine has a therapeutic window; doses >0.5 mg/kg are progressively less effective.¹⁵ Unlike the recommendation after esketamine administration, after receiving ketamine, patients remain in the care of their treatment team for <2 hours.

Esketamine, the S enantiomer of ketamine, was FDA-approved for TRD as an intranasal formulation. Esketamine is more commonly used than IV ketamine because it is FDA-approved and typically covered by insurance, but it may not be as effective.¹⁶ An economic analysis by Brendle et al¹⁷ suggested insurance companies would lower costs if they covered ketamine infusions vs intranasal esketamine.

Aducanumab and lecanemab

The most recent FDA-approved interventional agents are aducanumab and lecanemab, which are indicated for treating Alzheimer disease.^18,19 Both are human monoclonal antibodies that bind selectively and with high affinity to amyloid beta plaque aggregates and promote their removal by Fc receptor–mediated phagocytosis.²⁰

FDA approval of aducanumab and lecanemab was controversial. Initially, aducanumab’s safety monitoring board performed a futility analysis that suggested aducanumab was unlikely to separate from placebo, and the research was stopped.²¹ The manufacturer petitioned the FDA to consider the medication for accelerated approval on the basis of biomarker data showing that amyloid beta plaque aggregates become smaller. Current FDA approval is temporary to allow patients access to this potentially beneficial agent, but the manufacturer must supply clinical evidence that the reduction of amyloid beta plaques is associated with desirable changes in the course of Alzheimer disease, or risk losing the approval.

Lecanemab is also a human monoclonal antibody intended to remove amyloid beta plaques that was FDA-approved under the accelerated approval pathway.²² Unlike aducanumab, lecanemab demonstrated a statistically significant (although clinically imperceptible) reduction in the rate of cognitive decline; it did not show cognitive improvement.²³ Lecanemab also significantly reduced amyloid beta plaques.²³

Aducanumab and lecanemab are generally not covered by insurance and typically cost >$26,000 annually. Both are administered by IV infusion once a month. More monoclonal antibody medications for treating early Alzheimer disease are in the late stages of development, most notably donanebab.²⁴ Observations during clinical trials found that in the later stages of Alzheimer disease, forceful removal of plaques by the autoimmune process damages neurons, while in less dense deposits of early dementia such removal is not harmful to the cells and prevents amyloid buildup.

Brexanolone

Brexanolone is an aqueous formulation of allopregnanolone, a major metabolite of progesterone and a positive allosteric modulator of GABA-A receptors.²⁵ Its levels are maximal at the end of the third trimester of pregnancy and fall rapidly following delivery. Research showed a 3-day infusion was rapidly and significantly effective for treating postpartum depression²⁶ and brexanolone received FDA approval for this indication in March 2019.²⁷ However, various administrative, economic, insurance, and other hurdles make it difficult for patients to access this treatment. Despite its rapid onset of action (usually 48 hours), brexanolone takes an average of 15 days to go through the prior authorization process.²⁸ In addition to the need for prior authorization, the main impediment to the use of brexanolone is the 3-day infusion schedule, which greatly magnifies the cost but is partially circumvented by the availability of dedicated outpatient centers.

Magnesium

Magnesium is on the World Health Organization’s Model List of Essential Medicines.²⁹ There has been extensive research on the use of magnesium sulfate for psychiatric indications, especially for depression.³⁰ Magnesium functions similarly to calcium channel blockers by competitively blocking intracellular calcium channels, decreasing calcium availability, and inhibiting smooth muscle contractility.³¹ It also competes with calcium at the motor end plate, reducing excitation by inhibiting the release of acetylcholine.³² This property is used for high-dose IV magnesium treatment of impending preterm labor in obstetrics. Magnesium sulfate is the drug of choice in treating eclamptic seizures and preventing seizures in severe preeclampsia or gestational hypertension with severe features.³³ It is also used to treat torsade de pointes, severe asthma exacerbations, constipation, and barium poisoning.³⁴ Beneficial use in asthma treatment³⁵ and the treatment of migraine³⁶ have also been reported.

IV magnesium in myocardial infarction may be harmful,³⁷ though outside of acute cardiac events, magnesium is found to be safe.³⁸

Oral magnesium sulfate is a common over-the-counter anxiety remedy. As a general cell stabilizer (mediated by the reduction of intracellular calcium), magnesium is potentially beneficial outside of its muscle-relaxing properties, although muscle relaxing can benefit anxious patients. It is used to treat anxiety,³⁹ alcohol withdrawal,⁴⁰ and fear.⁴¹ Low magnesium blood levels are found in patients with depression, schizophrenia,⁴² and attention-deficit/hyperactivity disorder.⁴³ However, it is important to note that the therapeutic effect of magnesium when treating anxiety and headache is independent of preinfusion magnesium blood levels.⁴³

Continue to: The efficacy of oral magnesium...

The efficacy of oral magnesium is not robust. However, IV administration has a pronounced beneficial effect as an abortive and preventative treatment in many patients with anxiety.⁴⁴

IV administration of magnesium can produce adverse effects, including flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, and cardiac and CNS depression. These complications are very rare and dose-dependent.⁴⁵ Magnesium is excreted by the kidneys, and dosing must be decreased in patients with kidney failure. The most common adverse effect is local burning along the vein upon infusion; small doses of IV lidocaine can remedy this. Hot flashes are also common.⁴⁵

Various dosing strategies are available. In patients with anxiety, application dosing is based on the recommended preeclampsia IV dose of 4 g diluted in 250 mL of 5% dextrose. Much higher doses may be used in obstetrics. Unlike in obstetrics, for psychiatric indications, magnesium is administered over 60 to 90 minutes. Heart monitoring is recommended.

Scopolamine

Scopolamine is primarily used to relieve nausea, vomiting, and dizziness associated with motion sickness and recovery from anesthesia. It is also used in ophthalmology and in patients with excessive sweating. In off-label and experimental applications, scopolamine has been used in patients with TRD.⁴⁶

Scopolamine is an anticholinergic medication. It is a nonselective antagonist at muscarinic receptors.⁴⁷ Tricyclic antidepressants (TCAs) possess strong anticholinergic function. Newer generations of antidepressants were designed specifically not to have this function because it was believed to be an unwanted and potentially dangerous adverse effect. However, data suggest that anticholinergic action is important in decreasing depressive symptoms. Several hypotheses of anticholinergic effects on depression have been published since the 1970s. They include the cholinergic-adrenergic hypothesis,⁴⁸ acetylcholine predominance relative to adrenergic action hypothesis,⁴⁹ and insecticide poisoning observations.⁵⁰ Centrally acting physostigmine (but not peripherally acting neostigmine) was reported to control mania.^48,51 A genetic connection between the M2acetylcholine receptor in patients with major depressive disorder (MDD) and alcohol use disorder is also suggestive.⁵²

Continue to: Multiple animal studies show...

Multiple animal studies show direct improvement in mobility and a decrease in despair upon introducing anticholinergic substances.^53-55 The cholinergic theory of depression has been studied in several controlled clinical human studies.^56,57 Use of a short-acting anticholinergic glycopyrrolate during electroconvulsive therapy (ECT) may contribute to the procedure’s efficacy.

Human research shows scopolamine has a higher efficacy as an antidepressant and anti-anxiety medication in women than in men,⁵⁸ possibly because estrogen increases the activity of choline acetyltransferase and release of acetylcholine.^59,60 M2receptors mediate estrogen influence on the NMDAR, which may explain the anticholinergic effects of depression treatments in women.⁶¹

Another proposed mechanism of action of scopolamine is a potent inhibition of the NMDAR.⁶² Rapid treatments of depression may be based on this mechanism. Examples of such treatments include IV ketamine and sleep deprivation.⁶³ IV scopolamine shows potency in treating MDD and bipolar depression. This treatment should be reserved for patients who do not respond to or are not candidates for other usual treatment modalities of MDD and for the most severe cases. Scopolamine is 30 times more potent than amitriptyline in anticholinergic effect and reportedly produces sustained improvement in MDD.⁶⁴

Scopolamine has no black-box warnings. It has not been studied in pregnant women and is not recommended for use during pregnancy. Due to possible negative cardiovascular effects, a normal electrocardiogram is required before the start of treatment. Exercise caution in patients with glaucoma, benign prostatic enlargement, gastroparesis, unstable cardiovascular status, or severe renal impairment.

Treatment with scopolamine is not indicated for patients with myasthenia gravis, psychosis, or seizures. Patients must be off potassium for 3 days before beginning scopolamine treatment. Patients should consult with their cardiologist before having a scopolamine infusion. Adverse reactions may include psychosis, tachycardia, seizures, paralytic ileus, and glaucoma exacerbation. The most common adverse effects of scopolamine infusion treatment include drowsiness, dry mouth, blurred vision, lightheadedness, and dizziness. Due to possible drowsiness, operating motor vehicles or heavy machinery must be avoided on the day of treatment.⁶⁵ Overall, the adverse effects of scopolamine are preventable and manageable, and its antidepressant efficacy is noteworthy.⁶⁶

Continue to: Treatment typically consists of 3 consecutive infusions...

Treatment typically consists of 3 consecutive infusions of 4 mcg/kg separated by 3 to 5 days.⁵⁶ It is possible to have a longer treatment course if the patient experiences only partial improvement. Repeated courses or maintenance treatment (similar to ECT maintenance) are utilized in some patients if indicated. Cardiac monitoring is mandatory.

Clomipramine

Clomipramine, a TCA, acts as a preferential inhibitor of 5-hydroxytryptamine uptake and has proven effective in managing depression, TRD, and obsessive-compulsive disorder (OCD).⁶⁷ Although this medication has reported treatment benefits for patients with phobia, panic disorder,¹⁵ chronic pain,⁶⁸ Tourette syndrome,⁶⁹ premature ejaculation, anorexia nervosa,⁷⁰ cataplexy,⁴⁹ and enuresis,⁷¹ it is FDA-approved only for the treatment of OCD.⁷² Clomipramine may also be beneficial for pain and headache, possibly because of its anti-inflammatory action.⁷³ The anticholinergic effects of clomipramine may add to its efficacy in depression.

The pathophysiology of MDD is connected to hyperactivity of the HPA axis and elevated cortisol levels. Higher clomipramine plasma levels show a linear correlation with lower cortisol secretion and levels, possibly aiding in the treatment of MDD and anxiety.⁷⁴ The higher the blood level, the more pronounced clomipramine’s therapeutic effect across multiple domains.⁷⁵

IV infusion of clomipramine produces the highest concentration in the shortest time, but overall, research does not necessarily support increased efficacy of IV over oral administration. There is evidence suggesting that subgroups of patients with severe, treatment-refractory OCD may benefit from IV agents and research suggests a faster onset of action.⁷⁶ Faster onset of symptom relief is the basis for IV clomipramine use. In patients with OCD, it can take several months for oral medications to produce therapeutic benefits; not all patients can tolerate this. In such scenarios, IV administration may be considered, though it is not appropriate for routine use until more research is available. Patients with treatment-resistant OCD who have exhausted other means of symptom relief may also be candidates for IV treatment.

The adverse effects of IV clomipramine are no different from oral use, though they may be more pronounced. A pretreatment cardiac exam is desirable because clomipramine, like other TCAs, may be cardiotoxic. The anticholinergic adverse effects of TCAs are well known to clinicians⁷⁷ and partially explained in the scopolamine section of this article. It is not advisable to combine clomipramine with other TCAs or serotonin reuptake inhibitors. Clomipramine also should not be combined with monoamine oxidase inhibitors, though such a combination was reported in medical literature.⁷⁸ Combination with antiarrhythmics such as lidocaine or opioids such as fentanyl or and tramadol is highly discouraged (fentanyl and tramadol also have serotonergic effects).⁷⁹

Continue to: Clomipramine for IV use is not commercially available...

Clomipramine for IV use is not commercially available and must be sterilely compounded. The usual course of treatment is a series of 3 infusions: 150 mg on Day 1, 200 mg on Day 2 or Day 3, and 250 mg on Day 3, Day 4, or Day 5, depending on tolerability. A protocol with a 50 mg/d starting dose and titration up to a maximum dose of 225 mg/d over 5 to 7 days has been suggested for inpatient settings.⁶⁷ Titration to 250 mg is more common.⁸⁰

A longer series may be performed, but this increases the likelihood of adverse effects. Booster and maintenance treatments are also completed when required. Cardiac monitoring is mandatory.

Vortioxetine and citalopram

IV treatment of depression with vortioxetine and citalopram has been explored but has not yet taken hold in clinical psychiatry.^81,82

Injections and blocks

Three interventional approaches to treatment that possess psychotherapeutic potential include stellate ganglion blocks (SGBs), glabellar BT injections, and trigger point injections (TPIs). None of these are FDA-approved for psychiatric treatment.

Stellate ganglion blocks

The sympathetic nervous system is involved in autonomic hyperarousal and is at the core of posttraumatic symptomatology.⁸³ Insomnia, anxiety, irritability, hypervigilance, and other excitatory CNS events are connected to the sympathetic nervous system and amygdala activation is commonly observed in those exposed to extreme stress or traumatic events.⁸⁴

Continue to: SGBs were first performed 100 years ago...

SGBs were first performed 100 years ago and reported to have beneficial psychiatric effects at the end of the 1940s. In 1998 in Finland, improvement of posttraumatic stress disorder (PTSD) symptoms was observed accidentally via thoracic level spine blocks.⁸⁵ In 2006, cervical level sympathetic blocks were shown to be effective for PTSD symptom control.⁸⁶ By the end of 2010, Veterans Administration hospitals adopted SGBs to treat veterans with PTSD.^87,88 The first multisite, randomized clinical trial of SGB for PTSD confirmed multiple previous reports of treatment efficacy. Specifically, 2 SGB treatments 2 weeks apart effectively reduced total symptom severity scores over 8 weeks.⁸⁷

Since the stellate ganglion is connected to the amygdala, SGB has also been assessed for treating anxiety and depression.^89,90 Outside of PTSD, SGBs are used to treat complex regional pain syndrome,⁹¹ phantom limb pain, trigeminal neuralgia,⁹² intractable angina,⁹³ and postherpetic neuralgia in the head, neck, upper chest, or arms.⁹⁴ The procedure consists of an injection of a local anesthetic through a 25-gauge needle into the stellate sympathetic ganglion at the C6 or C7 vertebral levels. An injection into C6 is considered safer because of specific cervical spine anatomy. Ideally, fluoroscopic guidance or ultrasound is used to guide needle insertion.⁹⁵

A severe drop in blood pressure may be associated with SGBs and is mitigated by IV hydration. Other adverse effects include red eyes, drooping of the eyelids, nasal congestion, hoarseness, difficulty swallowing, a sensation of a “lump” in the throat, and a sensation of warmth or tingling in the arm or hand. Bilateral SGB is contraindicated due to the danger of respiratory arrest.⁹⁶

Glabellar BT injections

OnabotulinumtoxinA (BT) injection was first approved for therapeutic use in 1989 for eye muscle disorders such as strabismus⁹⁷ and blepharospasm.⁹⁸ It was later approved for several other indications, including cosmetic use, hyperhidrosis, migraine prevention, neurogenic bladder disorder, overactive bladder, urinary incontinence, and spasticity.^99-104 BT is used off-label for achalasia and sialorrhea.^105,106 Its mechanism of action is primarily attributed to muscle paralysis by blocking presynaptic acetylcholine release into neuromuscular junctions.¹⁰⁷

Facial BT injections are usually administered for cosmetic purposes, but smoothing forehead wrinkles and frown lines (the glabellar region of the face) both have antidepressant effects.¹⁰⁸ BT injections into the glabellar region also demonstrate antidepressant effects, particularly in patients with comorbid migraines and MDD.¹⁰⁹ Early case observations supported the independent benefit of the toxin on MDD when the toxin was injected into the glabellar region.^110,111 The most frequent protocol involves injections in the procerus and corrugator muscles.

Continue to: The facial feedback/emotional proprioception hypothesis...

The facial feedback/emotional proprioception hypothesis has dominated thinking about the mood-improving effects of BT. The theory is that blocking muscular expression of sadness (especially in the face) interrupts the experience of sadness; therefore, depression subsides.^112,113 However, BT injections in the muscles involved in the smile and an expression of positive emotions (lateral part of the musculus orbicularis oculi) have been associated with increased MDD scores.¹¹⁴ Thus, the mechanism clearly involves more than the cosmetic effect, since facial muscle injections in rats also have antidepressant effects.¹¹⁵

The use of progressive muscle relaxation is well-established in psychiatric treatment. The investigated conditions of increased muscle tone, especially torticollis and blepharospasm, are associated with MDD, and it may be speculated that proprioceptive feedback from the affected muscles may be causally involved in this association.^116-118 Activity of the corrugator muscle has been positively associated with increased amygdala activity.¹¹⁹ This suggests a potential similar mechanism to that hypothesized for SGB.

Alternatively, BT is commonly used to treat chronic conditions that may contribute to depression; its success in relieving the underlying problem may indirectly relieve MDD. Thus, in a postmarketing safety evaluation of BT, MDD was demonstrated 40% to 88% less often by patients treated with BT for 6 of the 8 conditions and injection sites, such as in spasms and spasticity of arms and legs, torticollis and neck pain, and axilla and palm injections for hyperhidrosis. In a parotid and submandibular glands BT injection subcohort, no patients experienced depressive symptoms.¹²⁰

Medicinal BT is generally considered safe. The most common adverse effects are hypersensitivity, injection site reactions, and other adverse effects specific to the injection site.¹²¹ Additionally, the cosmetic effects are transient, given the nature of the medication.

Trigger point injections

TPIs in the neck and shoulders are frequently used to treat tension headaches and various referred pain locations in the face and arms. Tension and depression frequently overlap in clinical practice.¹²² Relieving muscle tension (with resulting trigger points) improves muscle function and mood.

Continue to: The higher the number of active...

The higher the number of active trigger points (TPs), the greater the physical burden of headache and the higher the anxiety level. Gender differences in TP prevalence and TPI efficacy have been described in the literature. For example, the number of active TPs seems directly associated with anxiety levels in women but not in men.¹²³ Although TPs appear to be more closely associated with anxiety than depression,¹²⁴ depression associated with muscle tension does improve with TPIs. European studies have demonstrated a decrease in scores on the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale following TPI treatment.¹²⁵ The effect may be indirect, as when a patient’s pain is relieved, sleep and other psychiatric symptoms improve.¹²⁶

A randomized controlled trial by Castro Sánchez et al¹²⁷ demonstrated that dry needling therapy in patients with fibromyalgia syndrome (FMS) showed improvements in pain pressure thresholds, body pain, vitality, and social function, as well as total FMS symptoms, quality of sleep, anxiety, hospital anxiety and depression, general pain intensity, and fatigue.

Myofascial pain syndrome, catastrophizing, and muscle tension are common in patients with depression, anxiety, and somatization. Local TPI therapy aimed at inactivating pain generators is supported by moderate quality evidence. All manner of therapies have been described, including injection of saline, corticosteroids, local anesthetic agents, and dry needling. BT injections in chronic TPs are also practiced, though no specific injection therapy has been reliably shown to be more advantageous than another. The benefits of TPIs may be derived from the needle itself rather than from any specific substance injected. Stimulation of a local twitch response with direct needling of the TP appears of importance. There is no established consensus regarding the number of injection points, frequency of administration, and volume or type of injectate.¹²⁸

Adverse effects of TPIs relate to the nature of the invasive therapy, with the risk of tissue damage and bleeding. Pneumothorax risk is present with needle insertion at the neck and thorax.¹²⁹ Patients with diabetes may experience variations in blood sugar control if steroids are used.

Bottom Line

Interventional treatment modalities that may have a role in psychiatric treatment include IV administration of ketamine, aducanumab, lecanemab, brexanolone, magnesium, scopolamine, and clomipramine. Other interventional approaches include stellate ganglion blocks, glabellar botulinum toxin injections, and trigger point injections.

Advances in the understanding of neurobiological and neuro­psychiatric pathophysiology have opened new avenues of treatment for psychiatric patients. Historically, with a few exceptions, most psychiatric medications have been administered orally. However, many of the newer treatments require some form of specialized administration because they cannot be taken orally due to their chemical property (such as aducanumab); because there is the need to produce stable blood levels of the medication (such as brexanolone); because oral administration greatly diminished efficacy (such as oral vs IV magnesium or scopolamine), or because the treatment is focused on specific brain structures. This need for specialized administration has created a subspecialty called interventional psychiatry.

Part 1 of this 2-part article provides an overview of 1 type of interventional psychiatry: parenterally administered medications, including those administered via IV. We also describe 3 other interventional approaches to treatment: stellate ganglion blocks, glabellar botulinum toxin (BT) injections, and trigger point injections. In Part 2 we will review interventional approaches that involve neuromodulation.

Parenteral medications in psychiatry

In general, IV and IM medications can be more potent that oral medications due to their overall faster onset of action and higher blood concentrations. These more invasive forms of administration can have significant limitations, such as a risk of infection at the injection site, the need to be administered in a medical setting, additional time, and patient discomfort.

Table 1 lists short-acting injectable medications used in psychiatry, and Table 2 lists long-acting injectable medications. Parenteral administration of antipsychotics is performed to alleviate acute agitation or for chronic symptom control. These medications generally are not considered interventional treatments, but could be classified as such due to their invasive nature.¹ Furthermore, inhalable loxapine—which is indicated for managing acute agitation—requires a Risk Evaluation and Mitigation Strategy program consisting of 2 hours observation and monitoring of respiratory status.^2,3 Other indications for parenteral treatments include IM naltrexone extended release⁴ and subcutaneous injections of buprenorphine extended release⁵ and risperidone.⁶

IV administration

Most IV treatments described in this article are not FDA-approved for psychiatric treatment. Despite this, many interventional psychiatric treatments are part of clinical practice. IV infusion of ketamine is the most widely known and most researched of these. Table 3 lists other IV treatments that could be used as psychiatric treatment.

Ketamine

Since the early 1960s, ketamine has been used as a surgical anesthetic for animals. In the United States, it was approved for human surgical anesthesia in 1970. It was widely used during the Vietnam War due to its lack of inhibition of respiratory drive; medical staff first noticed an improvement in depressive symptoms and the resolution of suicidal ideation in patients who received ketamine. This led to further research on ketamine, particularly to determine its application in treatment-resistant depression (TRD) and other conditions.⁷ IV ketamine administration is most widely researched, but IM injections, intranasal sprays, and lozenges are also available. The dissociative properties of ketamine have led to its recreational use.⁸

Hypotheses for the mechanism of action of ketamine as an antidepressant include direct synaptic or extrasynaptic (GluN2B-selective), N-methyl-D-aspartate receptor (NMDAR) inhibition, selectively greater inhibition of NMDARs localized on GABAergic (gamma-aminobutyric acid) interneurons, and the role of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor activation. There are links between ketamine’s antidepressant actions and downstream mechanisms regulating synaptic plasticity, including brain-derived neurotrophic factor, eukaryotic elongation factor 2, mammalian target of rapamycin, and glycogen synthase kinase-3. Multiple other ketamine-associated mechanisms also have been described.^9,10 Action on the mu-opioid receptor is also known, possibly contributing to both antidepressant and anesthetic properties of ketamine.¹¹ Rapid onset of ketamine antidepressant action is especially valuable.¹²

Continue to: Ketamine is a schedule...

Ketamine is a schedule III medication with addictive properties. Delirium, panic attacks, hallucinations, nightmares, dysphoria, and paranoia may occur during and after use.¹³ Premedication with benzodiazepines, most notably lorazepam, is occasionally used to minimize ketamine’s adverse effects, but this generally is not recommended because doing so reduces ketamine’s antidepressant effects.¹⁴ Driving and operating heavy machinery is contraindicated after IV infusion. The usual protocol involves an IV infusion of ketamine 0.4 mg/kg to 1 mg/kg dosing over 1 hour. Doses between 0.4 mg/kg and 0.6 mg/kg are most common. Ketamine has a therapeutic window; doses >0.5 mg/kg are progressively less effective.¹⁵ Unlike the recommendation after esketamine administration, after receiving ketamine, patients remain in the care of their treatment team for <2 hours.

Esketamine, the S enantiomer of ketamine, was FDA-approved for TRD as an intranasal formulation. Esketamine is more commonly used than IV ketamine because it is FDA-approved and typically covered by insurance, but it may not be as effective.¹⁶ An economic analysis by Brendle et al¹⁷ suggested insurance companies would lower costs if they covered ketamine infusions vs intranasal esketamine.

Scopolamine is 30 times more potent than amitriptyline in anticholinergic effect and reportedly produces sustained improvement in MDD.⁶⁴

Scopolamine has no black-box warnings. It has not been studied in pregnant women and is not recommended for use during pregnancy. Due to possible negative cardiovascular effects, a normal electrocardiogram is required before the start of treatment. Exercise caution in patients with glaucoma, benign prostatic enlargement, gastroparesis, unstable cardiovascular status, or severe renal impairment.

Treatment with scopolamine is not indicated for patients with myasthenia gravis, psychosis, or seizures. Patients must be off potassium for 3 days before beginning scopolamine treatment. Patients should consult with their cardiologist before having a scopolamine infusion. Adverse reactions may include psychosis, tachycardia, seizures, paralytic ileus, and glaucoma exacerbation. The most common adverse effects of scopolamine infusion treatment include drowsiness, dry mouth, blurred vision, lightheadedness, and dizziness. Due to possible drowsiness, operating motor vehicles or heavy machinery must be avoided on the day of treatment.⁶⁵ Overall, the adverse effects of scopolamine are preventable and manageable, and its antidepressant efficacy is noteworthy.⁶⁶

Continue to: Treatment typically consists of 3 consecutive infusions...

Treatment typically consists of 3 consecutive infusions of 4 mcg/kg separated by 3 to 5 days.⁵⁶ It is possible to have a longer treatment course if the patient experiences only partial improvement. Repeated courses or maintenance treatment (similar to ECT maintenance) are utilized in some patients if indicated. Cardiac monitoring is mandatory.

Clomipramine

Clomipramine, a TCA, acts as a preferential inhibitor of 5-hydroxytryptamine uptake and has proven effective in managing depression, TRD, and obsessive-compulsive disorder (OCD).⁶⁷ Although this medication has reported treatment benefits for patients with phobia, panic disorder,¹⁵ chronic pain,⁶⁸ Tourette syndrome,⁶⁹ premature ejaculation, anorexia nervosa,⁷⁰ cataplexy,⁴⁹ and enuresis,⁷¹ it is FDA-approved only for the treatment of OCD.⁷² Clomipramine may also be beneficial for pain and headache, possibly because of its anti-inflammatory action.⁷³ The anticholinergic effects of clomipramine may add to its efficacy in depression.

The pathophysiology of MDD is connected to hyperactivity of the HPA axis and elevated cortisol levels. Higher clomipramine plasma levels show a linear correlation with lower cortisol secretion and levels, possibly aiding in the treatment of MDD and anxiety.⁷⁴ The higher the blood level, the more pronounced clomipramine’s therapeutic effect across multiple domains.⁷⁵

IV infusion of clomipramine produces the highest concentration in the shortest time, but overall, research does not necessarily support increased efficacy of IV over oral administration. There is evidence suggesting that subgroups of patients with severe, treatment-refractory OCD may benefit from IV agents and research suggests a faster onset of action.⁷⁶ Faster onset of symptom relief is the basis for IV clomipramine use. In patients with OCD, it can take several months for oral medications to produce therapeutic benefits; not all patients can tolerate this. In such scenarios, IV administration may be considered, though it is not appropriate for routine use until more research is available. Patients with treatment-resistant OCD who have exhausted other means of symptom relief may also be candidates for IV treatment.

The adverse effects of IV clomipramine are no different from oral use, though they may be more pronounced. A pretreatment cardiac exam is desirable because clomipramine, like other TCAs, may be cardiotoxic. The anticholinergic adverse effects of TCAs are well known to clinicians⁷⁷ and partially explained in the scopolamine section of this article. It is not advisable to combine clomipramine with other TCAs or serotonin reuptake inhibitors. Clomipramine also should not be combined with monoamine oxidase inhibitors, though such a combination was reported in medical literature.⁷⁸ Combination with antiarrhythmics such as lidocaine or opioids such as fentanyl or and tramadol is highly discouraged (fentanyl and tramadol also have serotonergic effects).⁷⁹

Continue to: Clomipramine for IV use is not commercially available...

Clomipramine for IV use is not commercially available and must be sterilely compounded. The usual course of treatment is a series of 3 infusions: 150 mg on Day 1, 200 mg on Day 2 or Day 3, and 250 mg on Day 3, Day 4, or Day 5, depending on tolerability. A protocol with a 50 mg/d starting dose and titration up to a maximum dose of 225 mg/d over 5 to 7 days has been suggested for inpatient settings.⁶⁷ Titration to 250 mg is more common.⁸⁰

A longer series may be performed, but this increases the likelihood of adverse effects. Booster and maintenance treatments are also completed when required. Cardiac monitoring is mandatory.

Vortioxetine and citalopram

IV treatment of depression with vortioxetine and citalopram has been explored but has not yet taken hold in clinical psychiatry.^81,82

Injections and blocks

Three interventional approaches to treatment that possess psychotherapeutic potential include stellate ganglion blocks (SGBs), glabellar BT injections, and trigger point injections (TPIs). None of these are FDA-approved for psychiatric treatment.

Stellate ganglion blocks

The sympathetic nervous system is involved in autonomic hyperarousal and is at the core of posttraumatic symptomatology.⁸³ Insomnia, anxiety, irritability, hypervigilance, and other excitatory CNS events are connected to the sympathetic nervous system and amygdala activation is commonly observed in those exposed to extreme stress or traumatic events.⁸⁴

Continue to: SGBs were first performed 100 years ago...

SGBs were first performed 100 years ago and reported to have beneficial psychiatric effects at the end of the 1940s. In 1998 in Finland, improvement of posttraumatic stress disorder (PTSD) symptoms was observed accidentally via thoracic level spine blocks.⁸⁵ In 2006, cervical level sympathetic blocks were shown to be effective for PTSD symptom control.⁸⁶ By the end of 2010, Veterans Administration hospitals adopted SGBs to treat veterans with PTSD.^87,88 The first multisite, randomized clinical trial of SGB for PTSD confirmed multiple previous reports of treatment efficacy. Specifically, 2 SGB treatments 2 weeks apart effectively reduced total symptom severity scores over 8 weeks.⁸⁷

Since the stellate ganglion is connected to the amygdala, SGB has also been assessed for treating anxiety and depression.^89,90 Outside of PTSD, SGBs are used to treat complex regional pain syndrome,⁹¹ phantom limb pain, trigeminal neuralgia,⁹² intractable angina,⁹³ and postherpetic neuralgia in the head, neck, upper chest, or arms.⁹⁴ The procedure consists of an injection of a local anesthetic through a 25-gauge needle into the stellate sympathetic ganglion at the C6 or C7 vertebral levels. An injection into C6 is considered safer because of specific cervical spine anatomy. Ideally, fluoroscopic guidance or ultrasound is used to guide needle insertion.⁹⁵

A severe drop in blood pressure may be associated with SGBs and is mitigated by IV hydration. Other adverse effects include red eyes, drooping of the eyelids, nasal congestion, hoarseness, difficulty swallowing, a sensation of a “lump” in the throat, and a sensation of warmth or tingling in the arm or hand. Bilateral SGB is contraindicated due to the danger of respiratory arrest.⁹⁶

Glabellar BT injections

OnabotulinumtoxinA (BT) injection was first approved for therapeutic use in 1989 for eye muscle disorders such as strabismus⁹⁷ and blepharospasm.⁹⁸ It was later approved for several other indications, including cosmetic use, hyperhidrosis, migraine prevention, neurogenic bladder disorder, overactive bladder, urinary incontinence, and spasticity.^99-104 BT is used off-label for achalasia and sialorrhea.^105,106 Its mechanism of action is primarily attributed to muscle paralysis by blocking presynaptic acetylcholine release into neuromuscular junctions.¹⁰⁷

Facial BT injections are usually administered for cosmetic purposes, but smoothing forehead wrinkles and frown lines (the glabellar region of the face) both have antidepressant effects.¹⁰⁸ BT injections into the glabellar region also demonstrate antidepressant effects, particularly in patients with comorbid migraines and MDD.¹⁰⁹ Early case observations supported the independent benefit of the toxin on MDD when the toxin was injected into the glabellar region.^110,111 The most frequent protocol involves injections in the procerus and corrugator muscles.

Continue to: The facial feedback/emotional proprioception hypothesis...

The facial feedback/emotional proprioception hypothesis has dominated thinking about the mood-improving effects of BT. The theory is that blocking muscular expression of sadness (especially in the face) interrupts the experience of sadness; therefore, depression subsides.^112,113 However, BT injections in the muscles involved in the smile and an expression of positive emotions (lateral part of the musculus orbicularis oculi) have been associated with increased MDD scores.¹¹⁴ Thus, the mechanism clearly involves more than the cosmetic effect, since facial muscle injections in rats also have antidepressant effects.¹¹⁵

The use of progressive muscle relaxation is well-established in psychiatric treatment. The investigated conditions of increased muscle tone, especially torticollis and blepharospasm, are associated with MDD, and it may be speculated that proprioceptive feedback from the affected muscles may be causally involved in this association.^116-118 Activity of the corrugator muscle has been positively associated with increased amygdala activity.¹¹⁹ This suggests a potential similar mechanism to that hypothesized for SGB.

Alternatively, BT is commonly used to treat chronic conditions that may contribute to depression; its success in relieving the underlying problem may indirectly relieve MDD. Thus, in a postmarketing safety evaluation of BT, MDD was demonstrated 40% to 88% less often by patients treated with BT for 6 of the 8 conditions and injection sites, such as in spasms and spasticity of arms and legs, torticollis and neck pain, and axilla and palm injections for hyperhidrosis. In a parotid and submandibular glands BT injection subcohort, no patients experienced depressive symptoms.¹²⁰

Medicinal BT is generally considered safe. The most common adverse effects are hypersensitivity, injection site reactions, and other adverse effects specific to the injection site.¹²¹ Additionally, the cosmetic effects are transient, given the nature of the medication.

Trigger point injections

TPIs in the neck and shoulders are frequently used to treat tension headaches and various referred pain locations in the face and arms. Tension and depression frequently overlap in clinical practice.¹²² Relieving muscle tension (with resulting trigger points) improves muscle function and mood.

Continue to: The higher the number of active...

The higher the number of active trigger points (TPs), the greater the physical burden of headache and the higher the anxiety level. Gender differences in TP prevalence and TPI efficacy have been described in the literature. For example, the number of active TPs seems directly associated with anxiety levels in women but not in men.¹²³ Although TPs appear to be more closely associated with anxiety than depression,¹²⁴ depression associated with muscle tension does improve with TPIs. European studies have demonstrated a decrease in scores on the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale following TPI treatment.¹²⁵ The effect may be indirect, as when a patient’s pain is relieved, sleep and other psychiatric symptoms improve.¹²⁶

A randomized controlled trial by Castro Sánchez et al¹²⁷ demonstrated that dry needling therapy in patients with fibromyalgia syndrome (FMS) showed improvements in pain pressure thresholds, body pain, vitality, and social function, as well as total FMS symptoms, quality of sleep, anxiety, hospital anxiety and depression, general pain intensity, and fatigue.

Myofascial pain syndrome, catastrophizing, and muscle tension are common in patients with depression, anxiety, and somatization. Local TPI therapy aimed at inactivating pain generators is supported by moderate quality evidence. All manner of therapies have been described, including injection of saline, corticosteroids, local anesthetic agents, and dry needling. BT injections in chronic TPs are also practiced, though no specific injection therapy has been reliably shown to be more advantageous than another. The benefits of TPIs may be derived from the needle itself rather than from any specific substance injected. Stimulation of a local twitch response with direct needling of the TP appears of importance. There is no established consensus regarding the number of injection points, frequency of administration, and volume or type of injectate.¹²⁸

Adverse effects of TPIs relate to the nature of the invasive therapy, with the risk of tissue damage and bleeding. Pneumothorax risk is present with needle insertion at the neck and thorax.¹²⁹ Patients with diabetes may experience variations in blood sugar control if steroids are used.

Bottom Line

Interventional treatment modalities that may have a role in psychiatric treatment include IV administration of ketamine, aducanumab, lecanemab, brexanolone, magnesium, scopolamine, and clomipramine. Other interventional approaches include stellate ganglion blocks, glabellar botulinum toxin injections, and trigger point injections.

Treating patients who are transgender or gender diverse (TGGD) requires an understanding of the social and psychological factors that have a unique impact on this population. As clinicians, it is our responsibility to understand the social, cultural, and political issues our patients face, both historically and currently. In this article, we provide information about the nature of gender and gender identity as separate from biological sex and informed by a person’s perception of self as male, female, nonbinary, or other variation.

Psychiatrists must be aware of how individuals who are TGGD have been perceived, classified, and treated by the medical profession, as this history is often a source of mistrust and a barrier to treatment for patients who need psychiatric care. This includes awareness of the “gatekeeping” role that persists in medical institutions today: applying strict eligibility criteria to determine the “fitness” of individuals who are transgender to pursue medical transition, as compared to the informed-consent model that is widely applied to other medical interventions. Our review of minority stress theory, as applicable to this patient population, provides a context and framework for empathic approaches to care for patients who are TGGD. Recognizing barriers to care and ways in which we can create a supportive environment for treatment will allow for tailored approaches that better fit the unique needs of this patient population.

The gender binary

In Western societies, gender has often been viewed as “binary,” oppositional, and directly correlated with physical sex or presumed anatomy.¹ The theory of gender essentialism insists that sex and gender are indistinguishable from one another and provide 2 “natural” and distinct categories: women and men. The “gender/sex” binary refers to the belief that individuals born with 2 X chromosomes will inherently develop into and fulfill the social roles of women, and those born with an X and a Y chromosome will develop into and fulfill the social roles of men.¹ In this context, “sex” refers to biological characteristics of individuals, including combinations of sex chromosomes, anatomy, and the development of sex characteristics during puberty. The term “gender” refers to the social, cultural, and behavioral aspects of being a man, woman, both, or neither, and “gender identity” refers to one’s internal, individual sense of self and experience of gender (Figure 1²). Many Western cultures are now facing destabilization of the gender/sex binary in social, political, and interpersonal contexts.¹ This is perhaps most clearly seen in the battle for self-determination and protection by laws affecting individuals who are transgender as well as the determination of other groups to maintain traditional sex and gender roles, often through political action. Historically, individuals who are TGGD have been present in a variety of cultures. For example, most Native American cultures have revered other-gendered individuals, more recently referred to as “two-spirited.” Similarly, the Bugis people of South Sulawesi, Indonesia, recognize 5 genders that exist on a non­binary spectrum.³

Despite its prevalence in Western society, scientific evidence for the gender/sex binary is lacking. The gender similarities hypothesis states that males and females are similar in most, but not all, psychological variables and is supported by multiple meta-analyses examining psychological gender differences.⁴ In a 2005 review of 46 meta-analyses of gender-differences, studied through behavior analysis, effect sizes for gender differences were trivial or small in almost 75% of examined variables.⁵ Analyzing for internal consistency among studies showing large gender/sex differences, Joel et al⁶ found that, on measures of personality traits, attitudes, interests, and behaviors were rarely homogenous in the brains of males or females. In fact, <1% of study participants showed only masculine or feminine traits, whereas 55% showed a combination, or mosaic, of these traits.⁶ These findings were supported by further research in behavioral neuroendocrinology that demonstrated a lack of hormonal evidence for 2 distinct sexes. Both estrogen (the “female” hormone) and testosterone (the “male” hormone) are produced by both biological males and females. Further, levels of estradiol do not significantly differ between males and females, and, in fact, in nonpregnant females, estradiol levels are more similar to those of males than to those of pregnant females.¹ In the last decade, imaging studies of the human brain have shown that brain structure and connectivity in individuals who are transgender are more similar to those of their experienced gender than of their natal sex.⁷ In social analyses of intersex individuals (individuals born with ambiguous physical sex characteristics), surgical assignment into the binary gender system did not improve—and often worsened—feelings of isolation and shame.¹

The National Institutes of Health defines gender as “socially constructed and enacted roles and behaviors which occur in a historical and cultural context and vary across societies and time.”⁸ The World Health Organization (WHO) provides a similar definition, and the evidence to support this exists in social-role theory, social-identity theory, and the stereotype-content model. However, despite evidence disputing a gender/sex binary, this method of classifying individuals into a dyad persists in many areas of modern culture, from gender-specific physical spaces (bathrooms, classrooms, store brands), language (pronouns), and laws. This desire for categorization helps fulfill social and psychological needs of groups and individuals by providing group identities and giving structure to the complexity of modern-day life. Identity and group membership provide a sense of belonging, source of self-esteem, and avoidance of ambiguity. Binary gender stereo­types provide expectations that allow anticipation and prediction of our social environments.⁹ However, the harm of perpetuating the false gender/sex binary is well documented and includes social and economic penalties, extreme violence, and even death. The field of medicine has not been immune from practices that implicitly endorse the gender/sex connection, as seen in the erroneous use of gender in biomedical writings at the highest levels and evidenced in research examining “gender” differences in disease incidence.

Gender diversity as a pathology

The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) has been a source of pathologizing gender diversity since the 1960s, with the introduction of “transsexualism” in DSM-II¹⁰ and “gender identity disorder of childhood” in DSM-III.¹¹ These diagnoses were listed under the headings of “sexual deviations” and “psychosexual disorders” in the respective DSM editions. This illustrates how gender diversity was viewed as a mental illness/defect. As the DSM developed through various revisions, so have these diagnoses. DSM-IV used the diagnosis “gender identity disorder.”¹² Psychiatry has evolved away from this line of thinking by focusing on the distress from biological sex characteristics that are “incongruent” with an individual’s gender identity, leading to the development of the gender dysphoria diagnosis.¹³ While this has been a positive step in psychiatry’s efforts to de-pathologize individuals who are gender-diverse, it raises the question: should such diagnoses be included in the DSM at all?

The gender dysphoria diagnosis continues to be needed by many individuals who are TGGD in order to access gender-affirming health care services. Mental health professionals are placed in a gatekeeping role by the expectation that they provide letters of “support” to indicate an individual is of sound mind and consistent gender identity to have services covered by insurance providers. In this way, the insurance industry and the field of medicine continue to believe that individuals who are TGGD need psychiatric permission and/or counsel regarding their gender identity. This can place psychiatry in a role of controlling access to necessary care while also creating a possible distrust in our ability to provide care to patients who are gender-diverse. This is particularly problematic given the high rates of depression, anxiety, trauma, and substance use within these communities.¹⁴ In the WHO’s ICD-11, gender dysphoria was changed to gender incongruence and is contained in the category of “Conditions related to sexual health.”¹⁵ This indicates continued evolution of how medicine views individuals who are TGGD, and offers hope that psychiatry and the DSM will follow suit.

Continue to: Minority stress theory

Ilan Meyer’s minority stress theory explores how cultural and social factors impact mental health functioning (Figure 2¹⁶). Minority stress theory, which was originally developed for what at the time was described as the lesbian, gay, and bisexual communities, purports that the higher prevalence of mental health disorders among such individuals is likely due to social stigma, discrimination, and stressors associated with minority status. More recently, minority stress theory has been expanded to provide framework for individuals who are TGGD. Hendricks et al¹⁷ explain how distal, proximal, and resilience factors contribute to mental health outcomes among these individuals. Distal factors, such as gender-related discrimination, harassment, violence, and rejection, explain how systemic, cultural, and environmental events lead to overt stress. Proximal factors consist of an individual’s expectation and anticipation of negative and stressful events and the internalization of negative attitudes and prejudice (ie, internalized transphobia). Resilience factors consist of community connectedness and within-group identification and can help mediate the negative effects of distal and proximal factors.

As clinicians, understanding our patients’ experiences and expectations can help us better engage with them and create an environment of safety and healing. Minority stress theory framework suggests that patients may start treatment with distrust or suspicion in light of previous negative experiences. They may also be likely to expect clinicians to be judgmental or to lack understanding of them. The 2015 US Transgender Survey found that 33% of individuals who are TGGD who sought medical treatment in the past year had at least 1 negative experience related to their gender identity (Table 1¹⁸). Twenty-four percent reported having to educate their clinician about people who are TGGD, while 15% reported the health care professional asked invasive or unnecessary questions about their gender status that were unrelated to their visit. While psychiatry is often distinct from the larger medical field, it is important to understand the negative encounters individuals who are TGGD have likely experienced in medicine, and how those events may skew their feelings about psychiatric treatment. This is especially salient given the higher prevalence of various psychiatric disorders among individuals who are TGGD.¹⁸

According to the US Transgender Survey, 39% of participants were currently experiencing serious psychological distress, which is nearly 8 times the rate in the US population (5%).¹⁸ When extrapolated, this data indicates that we in psychiatry are likely to work with individuals who identify as TGGD, regardless of our expertise. Additionally, research indicates that having access to gender-affirming care—such as hormone replacement therapy, gender-affirming surgery, voice therapy, and other treatments—greatly improves mental health issues such as anxiety, depression, and suicidality among individuals who are TGGD.^19,20 It is in this way we in psychiatry must do more than just care for our patients by becoming advocates for them to receive the care they need and deserve. While at times we may want to stay out of politics and other public discourse, it is becoming increasingly necessary as health care is entrenched in politics.

Clinical applicability

Because individuals who are TGGD experience higher rates of depression, anxiety, substance use, and other psychiatric disorders,¹⁴ it is increasingly likely that many clinicians will be presented with opportunities to treat such individuals. Despite high rates of psychiatric disorders, individuals who are TGGD often avoid treatment due to concerns about being pathologized, stereotyped, and/or encountering professionals who lack the knowledge to treat them as they are.²¹ Several studies recommend clinicians better equip themselves to appropriately provide services to individuals who are TGGD.²¹ Some advise seeking education to understand the unique needs of these patients and to help stay current with appropriate terminology and language (Table 2²²). This also implies not relying on patients to educate clinicians in understanding their specific needs and experiences.

Making assumptions about a patient’s identity is one of the most commonly reported issues by individuals who are TGGD. Therefore, it is critical to avoid making assumptions about patients based on binary stereotypes.^23,24 We can circumvent these mistakes by asking every patient for their name and pronouns, and introducing ourselves with our pronouns. This illustrates an openness and understanding of the importance of identity and language, and makes it common practice from the outset. Integrating the use of gender-neutral language into paperwork, intake forms, charting, and conversation will also help avoid the pitfalls of misgendering and making false assumptions. This will also allow for support staff, medical assistants, and others to use correct language with patients. Having a patient’s used name and pronouns visible for everyone who works with the patient is necessary to effectively meet the patient’s needs. Additionally, understanding that the range of experiences and needs for individuals who are TGGD is heterogeneous can help reduce assumptions and ensure we are asking for needed information. It is also important to ask for only relevant information needed to provide treatment.

Continue to: Resources are widely available...

Resources are widely available to aid in the care of individuals who are TGGD. In 2022, the World Professional Association for Transgender Health released new guidelines—Standards of Care 8—for working with individuals who are TGGD.²⁵ While these standards include a section dedicated to mental health, they also provide guidelines on education, assessments, specific demographic groups, hormone therapy, primary care, and sexual health. Additionally, while we may not want the role of gatekeeping for individuals to receive gender-affirming care, we work within a health care and insurance system that continues to require psychiatric assessment for such surgeries. In this role, we must do our part to educate ourselves in how to best provide these assessments and letters of support to help patients receive appropriate and life-saving care.

Finally, in order to provide a more comfortable and affirming space for individuals who are TGGD, develop ways to self-assess and monitor the policies, procedures, and language used within your practice, clinic, or institution. Monitoring the language used in charting to ensure consistency with the individual’s gender identity is important for our own understanding of the patient, and for patients to feel seen. This is especially true given patients’ access to medical records under the Cures Act. Moreover, it is essential to be cognizant of how you present clients to others in consultation or care coordination to ensure the patient is identified correctly and consistently by clinicians and staff.

Bottom Line

Understanding the social, cultural, and medical discrimination faced by patients who are transgender or gender diverse can make us better suited to engage and treat these individuals in an affirming and supportive way.

DSM-IV used the diagnosis “gender identity disorder.”¹² Psychiatry has evolved away from this line of thinking by focusing on the distress from biological sex characteristics that are “incongruent” with an individual’s gender identity, leading to the development of the gender dysphoria diagnosis.¹³ While this has been a positive step in psychiatry’s efforts to de-pathologize individuals who are gender-diverse, it raises the question: should such diagnoses be included in the DSM at all?

The gender dysphoria diagnosis continues to be needed by many individuals who are TGGD in order to access gender-affirming health care services. Mental health professionals are placed in a gatekeeping role by the expectation that they provide letters of “support” to indicate an individual is of sound mind and consistent gender identity to have services covered by insurance providers. In this way, the insurance industry and the field of medicine continue to believe that individuals who are TGGD need psychiatric permission and/or counsel regarding their gender identity. This can place psychiatry in a role of controlling access to necessary care while also creating a possible distrust in our ability to provide care to patients who are gender-diverse. This is particularly problematic given the high rates of depression, anxiety, trauma, and substance use within these communities.¹⁴ In the WHO’s ICD-11, gender dysphoria was changed to gender incongruence and is contained in the category of “Conditions related to sexual health.”¹⁵ This indicates continued evolution of how medicine views individuals who are TGGD, and offers hope that psychiatry and the DSM will follow suit.

Continue to: Minority stress theory

Ilan Meyer’s minority stress theory explores how cultural and social factors impact mental health functioning (Figure 2¹⁶). Minority stress theory, which was originally developed for what at the time was described as the lesbian, gay, and bisexual communities, purports that the higher prevalence of mental health disorders among such individuals is likely due to social stigma, discrimination, and stressors associated with minority status. More recently, minority stress theory has been expanded to provide framework for individuals who are TGGD. Hendricks et al¹⁷ explain how distal, proximal, and resilience factors contribute to mental health outcomes among these individuals. Distal factors, such as gender-related discrimination, harassment, violence, and rejection, explain how systemic, cultural, and environmental events lead to overt stress. Proximal factors consist of an individual’s expectation and anticipation of negative and stressful events and the internalization of negative attitudes and prejudice (ie, internalized transphobia). Resilience factors consist of community connectedness and within-group identification and can help mediate the negative effects of distal and proximal factors.

As clinicians, understanding our patients’ experiences and expectations can help us better engage with them and create an environment of safety and healing. Minority stress theory framework suggests that patients may start treatment with distrust or suspicion in light of previous negative experiences. They may also be likely to expect clinicians to be judgmental or to lack understanding of them. The 2015 US Transgender Survey found that 33% of individuals who are TGGD who sought medical treatment in the past year had at least 1 negative experience related to their gender identity (Table 1¹⁸). Twenty-four percent reported having to educate their clinician about people who are TGGD, while 15% reported the health care professional asked invasive or unnecessary questions about their gender status that were unrelated to their visit. While psychiatry is often distinct from the larger medical field, it is important to understand the negative encounters individuals who are TGGD have likely experienced in medicine, and how those events may skew their feelings about psychiatric treatment. This is especially salient given the higher prevalence of various psychiatric disorders among individuals who are TGGD.¹⁸

According to the US Transgender Survey, 39% of participants were currently experiencing serious psychological distress, which is nearly 8 times the rate in the US population (5%).¹⁸ When extrapolated, this data indicates that we in psychiatry are likely to work with individuals who identify as TGGD, regardless of our expertise. Additionally, research indicates that having access to gender-affirming care—such as hormone replacement therapy, gender-affirming surgery, voice therapy, and other treatments—greatly improves mental health issues such as anxiety, depression, and suicidality among individuals who are TGGD.^19,20 It is in this way we in psychiatry must do more than just care for our patients by becoming advocates for them to receive the care they need and deserve. While at times we may want to stay out of politics and other public discourse, it is becoming increasingly necessary as health care is entrenched in politics.

Clinical applicability

Because individuals who are TGGD experience higher rates of depression, anxiety, substance use, and other psychiatric disorders,¹⁴ it is increasingly likely that many clinicians will be presented with opportunities to treat such individuals. Despite high rates of psychiatric disorders, individuals who are TGGD often avoid treatment due to concerns about being pathologized, stereotyped, and/or encountering professionals who lack the knowledge to treat them as they are.²¹ Several studies recommend clinicians better equip themselves to appropriately provide services to individuals who are TGGD.²¹ Some advise seeking education to understand the unique needs of these patients and to help stay current with appropriate terminology and language (Table 2²²). This also implies not relying on patients to educate clinicians in understanding their specific needs and experiences.

Making assumptions about a patient’s identity is one of the most commonly reported issues by individuals who are TGGD. Therefore, it is critical to avoid making assumptions about patients based on binary stereotypes.^23,24 We can circumvent these mistakes by asking every patient for their name and pronouns, and introducing ourselves with our pronouns. This illustrates an openness and understanding of the importance of identity and language, and makes it common practice from the outset. Integrating the use of gender-neutral language into paperwork, intake forms, charting, and conversation will also help avoid the pitfalls of misgendering and making false assumptions. This will also allow for support staff, medical assistants, and others to use correct language with patients. Having a patient’s used name and pronouns visible for everyone who works with the patient is necessary to effectively meet the patient’s needs. Additionally, understanding that the range of experiences and needs for individuals who are TGGD is heterogeneous can help reduce assumptions and ensure we are asking for needed information. It is also important to ask for only relevant information needed to provide treatment.

Continue to: Resources are widely available...

Resources are widely available to aid in the care of individuals who are TGGD. In 2022, the World Professional Association for Transgender Health released new guidelines—Standards of Care 8—for working with individuals who are TGGD.²⁵ While these standards include a section dedicated to mental health, they also provide guidelines on education, assessments, specific demographic groups, hormone therapy, primary care, and sexual health. Additionally, while we may not want the role of gatekeeping for individuals to receive gender-affirming care, we work within a health care and insurance system that continues to require psychiatric assessment for such surgeries. In this role, we must do our part to educate ourselves in how to best provide these assessments and letters of support to help patients receive appropriate and life-saving care.

Finally, in order to provide a more comfortable and affirming space for individuals who are TGGD, develop ways to self-assess and monitor the policies, procedures, and language used within your practice, clinic, or institution. Monitoring the language used in charting to ensure consistency with the individual’s gender identity is important for our own understanding of the patient, and for patients to feel seen. This is especially true given patients’ access to medical records under the Cures Act. Moreover, it is essential to be cognizant of how you present clients to others in consultation or care coordination to ensure the patient is identified correctly and consistently by clinicians and staff.

Bottom Line

Understanding the social, cultural, and medical discrimination faced by patients who are transgender or gender diverse can make us better suited to engage and treat these individuals in an affirming and supportive way.

Treating patients who are transgender or gender diverse (TGGD) requires an understanding of the social and psychological factors that have a unique impact on this population. As clinicians, it is our responsibility to understand the social, cultural, and political issues our patients face, both historically and currently. In this article, we provide information about the nature of gender and gender identity as separate from biological sex and informed by a person’s perception of self as male, female, nonbinary, or other variation.

Psychiatrists must be aware of how individuals who are TGGD have been perceived, classified, and treated by the medical profession, as this history is often a source of mistrust and a barrier to treatment for patients who need psychiatric care. This includes awareness of the “gatekeeping” role that persists in medical institutions today: applying strict eligibility criteria to determine the “fitness” of individuals who are transgender to pursue medical transition, as compared to the informed-consent model that is widely applied to other medical interventions. Our review of minority stress theory, as applicable to this patient population, provides a context and framework for empathic approaches to care for patients who are TGGD. Recognizing barriers to care and ways in which we can create a supportive environment for treatment will allow for tailored approaches that better fit the unique needs of this patient population.

The gender binary

In Western societies, gender has often been viewed as “binary,” oppositional, and directly correlated with physical sex or presumed anatomy.¹ The theory of gender essentialism insists that sex and gender are indistinguishable from one another and provide 2 “natural” and distinct categories: women and men. The “gender/sex” binary refers to the belief that individuals born with 2 X chromosomes will inherently develop into and fulfill the social roles of women, and those born with an X and a Y chromosome will develop into and fulfill the social roles of men.¹ In this context, “sex” refers to biological characteristics of individuals, including combinations of sex chromosomes, anatomy, and the development of sex characteristics during puberty. The term “gender” refers to the social, cultural, and behavioral aspects of being a man, woman, both, or neither, and “gender identity” refers to one’s internal, individual sense of self and experience of gender (Figure 1²). Many Western cultures are now facing destabilization of the gender/sex binary in social, political, and interpersonal contexts.¹ This is perhaps most clearly seen in the battle for self-determination and protection by laws affecting individuals who are transgender as well as the determination of other groups to maintain traditional sex and gender roles, often through political action. Historically, individuals who are TGGD have been present in a variety of cultures. For example, most Native American cultures have revered other-gendered individuals, more recently referred to as “two-spirited.” Similarly, the Bugis people of South Sulawesi, Indonesia, recognize 5 genders that exist on a non­binary spectrum.³

Despite its prevalence in Western society, scientific evidence for the gender/sex binary is lacking. The gender similarities hypothesis states that males and females are similar in most, but not all, psychological variables and is supported by multiple meta-analyses examining psychological gender differences.⁴ In a 2005 review of 46 meta-analyses of gender-differences, studied through behavior analysis, effect sizes for gender differences were trivial or small in almost 75% of examined variables.⁵ Analyzing for internal consistency among studies showing large gender/sex differences, Joel et al⁶ found that, on measures of personality traits, attitudes, interests, and behaviors were rarely homogenous in the brains of males or females. In fact, <1% of study participants showed only masculine or feminine traits, whereas 55% showed a combination, or mosaic, of these traits.⁶ These findings were supported by further research in behavioral neuroendocrinology that demonstrated a lack of hormonal evidence for 2 distinct sexes. Both estrogen (the “female” hormone) and testosterone (the “male” hormone) are produced by both biological males and females. Further, levels of estradiol do not significantly differ between males and females, and, in fact, in nonpregnant females, estradiol levels are more similar to those of males than to those of pregnant females.¹ In the last decade, imaging studies of the human brain have shown that brain structure and connectivity in individuals who are transgender are more similar to those of their experienced gender than of their natal sex.⁷ In social analyses of intersex individuals (individuals born with ambiguous physical sex characteristics), surgical assignment into the binary gender system did not improve—and often worsened—feelings of isolation and shame.¹

The National Institutes of Health defines gender as “socially constructed and enacted roles and behaviors which occur in a historical and cultural context and vary across societies and time.”⁸ The World Health Organization (WHO) provides a similar definition, and the evidence to support this exists in social-role theory, social-identity theory, and the stereotype-content model. However, despite evidence disputing a gender/sex binary, this method of classifying individuals into a dyad persists in many areas of modern culture, from gender-specific physical spaces (bathrooms, classrooms, store brands), language (pronouns), and laws. This desire for categorization helps fulfill social and psychological needs of groups and individuals by providing group identities and giving structure to the complexity of modern-day life. Identity and group membership provide a sense of belonging, source of self-esteem, and avoidance of ambiguity. Binary gender stereo­types provide expectations that allow anticipation and prediction of our social environments.⁹ However, the harm of perpetuating the false gender/sex binary is well documented and includes social and economic penalties, extreme violence, and even death. The field of medicine has not been immune from practices that implicitly endorse the gender/sex connection, as seen in the erroneous use of gender in biomedical writings at the highest levels and evidenced in research examining “gender” differences in disease incidence.

Gender diversity as a pathology

The American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) has been a source of pathologizing gender diversity since the 1960s, with the introduction of “transsexualism” in DSM-II¹⁰ and “gender identity disorder of childhood” in DSM-III.¹¹ These diagnoses were listed under the headings of “sexual deviations” and “psychosexual disorders” in the respective DSM editions.

The benefits of living a balanced life is a very popular concept. But I beg to differ. Balance in one’s life is overrated. Allocating equal time to the various components of one’s life may sound admirable, but it is a recipe for an ordinary life, with no major achievements or a memorable legacy. Scoring a “moonshot” achievement while living a balanced life is highly unlikely.

The benefits of deliberately leading an “asymmetric life” is an epiphany I acquired as a young boy addicted to watching stellar Olympic athletes win gold medals. I dreamed about being the best in the world in a sport, or in something else. As I read about the lives of my Olympic idols, my mind was opened to the fact that each of them led an unbalanced life in the pursuit of their cherished goal to be the best in the world: a gold medalist. I found out that for several years before the Olympic games, these athletes spent a disproportionate amount of their waking time (≥10 hours a day) practicing their sport, strengthening their muscles, building up their stamina, and honing their physical skills and mental toughness. Those sacrifices were necessary—in fact, indispensable—to set themselves apart from us mere mortals. Their social life was quite restricted, and even their educational pursuits had to be reduced or deferred.

I realized at a young age that to be the world’s best athlete, one must lead a purpose-driven life and channel a tremendous amount of time and energy to achieve the cherished goal of an Olympic gold medal. I understood the sacrifices necessary to excel in sports, and concluded the same was also true outside of sports, such as for Nobel Laureates, world-class pianists, prodigious authors, ballet dancers, opera divas, or self-employed entrepreneurs.

As I grew up, I repeatedly heard people praise “the balanced life,” but in my heart, I knew that was a fallacy. I had already decided in high school that I wanted to become a psychiatric physician. I was a premed major in college and very aware that our medical school enrolled only 44 students into the Med 1 class. There were >350 other premed undergraduates. Thus, without hesitation, and with gusto, I deliberately led an unbalanced life, studying countless hours each day to achieve an A grade in all required and elective courses to earn a spot on the Dean’s list. I already had confidence in my academic skills because of my excellent performance in high school, but I was not going to take any chances because I recalled a quote commonly attributed to Thomas Edison: “Genius is 1% inspiration and 99% perspiration.” This is obviously antithetical to living a balanced life.

I matriculated in medical school, and my unbalanced lifestyle continued unabated. Most readers of this journal are fellow physicians who know well the heavy demands of medical school on our lives, in both the preclinical and clinical years. Trying to lead a balanced life during the 4 years of medical school can have disastrous consequences. We all led an “asymmetric existence” with 75% (or more) of our waking hours invested in our careers and 25% (or less) directed to our social lives (and fortunately, our families and friends generally understood). That is what it takes to earn the coveted MD, the equivalent of an Olympic medal for intellectual athletes.

Then came 4 more years of psychiatric residency training, and the long hours of work continued, along with many nights and weekends on call. As a resident, I treasured the modest but precious amount of time I had outside work. I was lucky to have a very supportive and competent wife (a psychologist), who spared me from having to wake up at night to feed our first baby or do various household chores, so I could read the many articles and books on my desk and catch up on my sleep after my frequent night and weekend call shifts.

My unbalanced life continued when I pursued a postresidency fellowship at the National Institutes of Health, where I conducted numerous clinical research trials, brain imaging studies, and postmortem research on a large collection of brains from deceased patients with schizophrenia or bipolar disorder. I worked 12 to 15 hours a day to write up the data I had collected, submit it to scientific journals, and revise it as needed. I knew from the strategic plan I had set for my life that the neuroscience fellowship would launch my academic career, and indeed it did.

Fast forward 30 years and you will still find me leading an unbalanced but joyful and fulfilling life. People often ask me how I was able to achieve so much (authoring several hundred scientific publications; publishing 13 books; receiving dozens of grants; editing 3 scientific journals; founding an international schizophrenia society; assuming many leadership positions, including becoming a department chair at 2 universities and being elected to the presidency of several associations; lecturing around the world and making hundreds of scientific presentations at national and international conferences; seeing thousands of patients; teaching, supervising, and mentoring countless medical students, psychiatric residents, and young faculty members; and creating a nonprofit foundation [CURESZ.org] with a former patient who recovered completely after 5 years of home classes and treatment-refractory command hallucinations who then graduated from college with honors in molecular biology after I prescribed clozapine to “cure” her from what was deemed a hopeless and irreversible mental disability¹). In all, thanks to my unbalanced life, I have achieved 12 moonshots and each is a major achievement of which I am proud.

My answer to those who ask me how I did all that is simple: I have strategically led an unbalanced life, enjoying every minute of it, and reaping the fruits of my labor. I do not waste an inordinate amount of time watching TV or participating in social media like many others might. And more importantly, despite this unbalanced life, I have been married to my college sweetheart for several decades and have a son and a daughter who are very high achievers and make me proud. I do budget time to regularly take my children and grandchildren on family vacations to exotic locations. I have dinner with my family every night. I am very happy with this so-called unbalanced life. I have received numerous awards and recognitions for my accomplishments, including the Distinguished Scholar Award (the highest academic recognition at The Ohio State University), the coveted Stanley Dean Award for research into schizophrenia from the American College of Psychiatrists, 4 Golden Apple Teaching Awards, and the Daniel Drake Medal, the highest honor that the University of Cincinnati College of Medicine bestows on a faculty member. (Dr. Drake founded the University of Cincinnati College of Medicine 200 years ago, a major moonshot, and among his many accomplishments, he also established the first psychiatric hospital in Ohio, another consequential moonshot. I am sure he led a very productive, unbalanced life, and that is why he is still remembered and revered 200 years later.)

It is said that at the height of his prominence 90 years ago, Sigmund Freud was asked, “What is life all about?” He responded with 2 words: “Liebe und arbeit” (love and work). Importantly, he did not specify which proportions those 2 major functions should occupy in one’s life. It was left up to each individual to make that choice. In the constitution of our country, that freedom of choice is the secret sauce of “the pursuit of happiness.”

The benefits of living a balanced life is a very popular concept. But I beg to differ. Balance in one’s life is overrated. Allocating equal time to the various components of one’s life may sound admirable, but it is a recipe for an ordinary life, with no major achievements or a memorable legacy.

I have received numerous awards and recognitions for my accomplishments, including the Distinguished Scholar Award (the highest academic recognition at The Ohio State University), the coveted Stanley Dean Award for research into schizophrenia from the American College of Psychiatrists, 4 Golden Apple Teaching Awards, and the Daniel Drake Medal, the highest honor that the University of Cincinnati College of Medicine bestows on a faculty member. (Dr. Drake founded the University of Cincinnati College of Medicine 200 years ago, a major moonshot, and among his many accomplishments, he also established the first psychiatric hospital in Ohio, another consequential moonshot. I am sure he led a very productive, unbalanced life, and that is why he is still remembered and revered 200 years later.)

It is said that at the height of his prominence 90 years ago, Sigmund Freud was asked, “What is life all about?” He responded with 2 words: “Liebe und arbeit” (love and work). Importantly, he did not specify which proportions those 2 major functions should occupy in one’s life. It was left up to each individual to make that choice. In the constitution of our country, that freedom of choice is the secret sauce of “the pursuit of happiness.”

The benefits of living a balanced life is a very popular concept. But I beg to differ. Balance in one’s life is overrated. Allocating equal time to the various components of one’s life may sound admirable, but it is a recipe for an ordinary life, with no major achievements or a memorable legacy. Scoring a “moonshot” achievement while living a balanced life is highly unlikely.

The benefits of deliberately leading an “asymmetric life” is an epiphany I acquired as a young boy addicted to watching stellar Olympic athletes win gold medals. I dreamed about being the best in the world in a sport, or in something else. As I read about the lives of my Olympic idols, my mind was opened to the fact that each of them led an unbalanced life in the pursuit of their cherished goal to be the best in the world: a gold medalist. I found out that for several years before the Olympic games, these athletes spent a disproportionate amount of their waking time (≥10 hours a day) practicing their sport, strengthening their muscles, building up their stamina, and honing their physical skills and mental toughness. Those sacrifices were necessary—in fact, indispensable—to set themselves apart from us mere mortals. Their social life was quite restricted, and even their educational pursuits had to be reduced or deferred.

I realized at a young age that to be the world’s best athlete, one must lead a purpose-driven life and channel a tremendous amount of time and energy to achieve the cherished goal of an Olympic gold medal. I understood the sacrifices necessary to excel in sports, and concluded the same was also true outside of sports, such as for Nobel Laureates, world-class pianists, prodigious authors, ballet dancers, opera divas, or self-employed entrepreneurs.

As I grew up, I repeatedly heard people praise “the balanced life,” but in my heart, I knew that was a fallacy. I had already decided in high school that I wanted to become a psychiatric physician. I was a premed major in college and very aware that our medical school enrolled only 44 students into the Med 1 class. There were >350 other premed undergraduates. Thus, without hesitation, and with gusto, I deliberately led an unbalanced life, studying countless hours each day to achieve an A grade in all required and elective courses to earn a spot on the Dean’s list. I already had confidence in my academic skills because of my excellent performance in high school, but I was not going to take any chances because I recalled a quote commonly attributed to Thomas Edison: “Genius is 1% inspiration and 99% perspiration.” This is obviously antithetical to living a balanced life.

I matriculated in medical school, and my unbalanced lifestyle continued unabated. Most readers of this journal are fellow physicians who know well the heavy demands of medical school on our lives, in both the preclinical and clinical years. Trying to lead a balanced life during the 4 years of medical school can have disastrous consequences. We all led an “asymmetric existence” with 75% (or more) of our waking hours invested in our careers and 25% (or less) directed to our social lives (and fortunately, our families and friends generally understood). That is what it takes to earn the coveted MD, the equivalent of an Olympic medal for intellectual athletes.

Then came 4 more years of psychiatric residency training, and the long hours of work continued, along with many nights and weekends on call. As a resident, I treasured the modest but precious amount of time I had outside work. I was lucky to have a very supportive and competent wife (a psychologist), who spared me from having to wake up at night to feed our first baby or do various household chores, so I could read the many articles and books on my desk and catch up on my sleep after my frequent night and weekend call shifts.

My unbalanced life continued when I pursued a postresidency fellowship at the National Institutes of Health, where I conducted numerous clinical research trials, brain imaging studies, and postmortem research on a large collection of brains from deceased patients with schizophrenia or bipolar disorder. I worked 12 to 15 hours a day to write up the data I had collected, submit it to scientific journals, and revise it as needed. I knew from the strategic plan I had set for my life that the neuroscience fellowship would launch my academic career, and indeed it did.

Fast forward 30 years and you will still find me leading an unbalanced but joyful and fulfilling life. People often ask me how I was able to achieve so much (authoring several hundred scientific publications; publishing 13 books; receiving dozens of grants; editing 3 scientific journals; founding an international schizophrenia society; assuming many leadership positions, including becoming a department chair at 2 universities and being elected to the presidency of several associations; lecturing around the world and making hundreds of scientific presentations at national and international conferences; seeing thousands of patients; teaching, supervising, and mentoring countless medical students, psychiatric residents, and young faculty members; and creating a nonprofit foundation [CURESZ.org] with a former patient who recovered completely after 5 years of home classes and treatment-refractory command hallucinations who then graduated from college with honors in molecular biology after I prescribed clozapine to “cure” her from what was deemed a hopeless and irreversible mental disability¹). In all, thanks to my unbalanced life, I have achieved 12 moonshots and each is a major achievement of which I am proud.

My answer to those who ask me how I did all that is simple: I have strategically led an unbalanced life, enjoying every minute of it, and reaping the fruits of my labor. I do not waste an inordinate amount of time watching TV or participating in social media like many others might. And more importantly, despite this unbalanced life, I have been married to my college sweetheart for several decades and have a son and a daughter who are very high achievers and make me proud. I do budget time to regularly take my children and grandchildren on family vacations to exotic locations. I have dinner with my family every night. I am very happy with this so-called unbalanced life. I have received numerous awards and recognitions for my accomplishments, including the Distinguished Scholar Award (the highest academic recognition at The Ohio State University), the coveted Stanley Dean Award for research into schizophrenia from the American College of Psychiatrists, 4 Golden Apple Teaching Awards, and the Daniel Drake Medal, the highest honor that the University of Cincinnati College of Medicine bestows on a faculty member. (Dr. Drake founded the University of Cincinnati College of Medicine 200 years ago, a major moonshot, and among his many accomplishments, he also established the first psychiatric hospital in Ohio, another consequential moonshot.
