Neurology

An experimental therapy that uses deep brain stimulation (DBS) to deliver precise electrical pulses to an area deep inside the brain restored executive function in patients with moderate to severe traumatic brain injury (msTBI) and chronic sequelae.

Participants in this first-in-humans trial experienced brain injuries between 3-18 years before the study that left them with persistent neuropsychological impairment and a range of functional disabilities.

This is the first time a DBS device has been implanted in the central thalamus in humans, an area of the brain measuring only a few millimeters wide that helps regulate consciousness.

Placing the electrodes required a novel surgical technique developed by the investigators that included virtual models of each participant’s brain, microelectrode recording, and neuroimaging to identify neuronal circuits affected by the TBI.

After 3 months of 12-hour daily DBS treatments, participants’ performance on cognitive tests improved by an average of 32% from baseline. Participants were able to read books, watch TV shows, play video games, complete schoolwork, and felt significantly less fatigued during the day.

Although the small trial only included five patients, the work is already being hailed by other experts as significant.“We were looking for partial restoration of executive attention and expected [the treatment] would have an effect, but I wouldn’t have anticipated the effect size we saw,” co-lead investigator Nicholas Schiff, MD, professor of neuroscience at Weill Cornell Medical College, New York City, said in an interview.

The findings were published online Dec. 4 in Nature Medicine.

“No Trivial Feat”

An estimated 5.3 million children and adults are living with a permanent TBI-related disability in the US today. There currently is no effective therapy for impaired attention, executive function, working memory or information-processing speed caused by the initial injury.

Previous research suggests that a loss of activity in key brain circuits in the thalamus may be associated with a loss of cognitive function.

The investigators recruited six adults (four men and two women) between the ages of 22 and 60 years with a history of msTBI and chronic neuropsychological impairment and functional disability. One participant was later withdrawn from the trial for protocol noncompliance.

Participants completed a range of questionnaires and tests to establish baseline cognitive, psychological, and quality-of-life status.

To restore lost executive functioning in the brain, investigators had to target not only the central lateral nucleus, but also the neuronal network connected to the region that reaches other parts of the brain.

“To do both of those things we had to develop a whole toolset in order to model both the target and trajectory, which had to be right to make it work properly,” co-lead investigator Jaimie Henderson, MD, professor of neurosurgery at Stanford University College of Medicine, Stanford, California, said in an interview. “That gave us a pretty narrow window in which to work and getting an electrode accurately to this target is not a trivial feat.”

“A Moving Target”

Each participant’s brain physiology was slightly different, meaning the path that worked for one individual might not work for another. The surgery was further complicated by shifting in the brain that occurred as individual electrodes were placed.

“It was a literal moving target,” Dr. Henderson said.

In the beginning, investigators used microelectrode recording to “listen” to individual neurons to see which ones weren’t firing correctly.

When that method failed to offer the precise information needed for electrode placement, the investigators switched to neuroimaging, which allowed them to complete the surgery more quickly and accurately.

Participants remained in the hospital 1-2 days after surgery. They returned for postoperative imaging 30 days after surgery and were randomly assigned to different schedules for a 14-day titration period to optimize DBS stimulation.

The primary outcome was a 10% improvement on part B of the trail-making test, a neuropsychological test that measures executive functioning.

After 90 days of 12-hour daily DBS treatments, participants’ scores increased 15%–52% (average 32%) from baseline. Participants also reported an average of 33% decline in fatigue, one of the most common side effects of msTBI, and an average 80% improvement in attention.

The main safety risk during the 3- to-4-hour procedure is bleeding, which didn’t affect any of the participants in this study. One participant developed a surgical site infection, but all other side effects were mild.

After the 90-day treatment period, the study plan called for patients to be randomly assigned to a blinded withdrawal of treatment, with the DBS turned off for 21 days. Two of the patients declined to be randomized. DBS was turned off in one participant while the other two continued as normal.

After 3 weeks, the patient whose DBS was turned off showed a 34% decline on cognitive tests. The device was reactivated after the study and that participant has since reported improvements.

The DBS devices continue to function in all participants. Although their performance is not being measured as part of the study, anecdotal reports indicate sustained improvement in executive functioning.

“The brain injury causes this global down-regulation of brain function and what we think that this is doing is turning that back up again,” Dr. Henderson said. “At a very simplistic level, what we’re trying to do is turn the lights back up after the dimmer switch is switched down from the injury.”

New Hope

TBI patients are usually treated aggressively during the first year, when significant improvements are most likely, but there are few therapeutic options beyond that time, said neurologist Javier Cardenas, MD, who commented on the findings for this article.

“Many providers throw their hands up after a year in terms of intervention and then we’re always looking at potential declines over time,” said Dr. Cardenas, director of the Concussion and Brain Injury Center at the Rockefeller Neuroscience Institution, West Virginia University, Morgantown. “Most people plateau and don’t decline but we’re always worried about a secondary decline in traumatic brain injury.”Surgery is usually only employed immediately following the brain injury. The notion of surgery as a therapeutic option years after the initial assault on the brain is novel, said Jimmy Yang, MD, assistant professor of neurologic surgery at Ohio State University College of Medicine, Columbus, who commented on the findings for this article.

“While deep brain stimulation surgery in clinical practice is specifically tailored to each patient we treat, this study goes a step further by integrating research tools that have not yet made it to the clinical realm,” Dr. Yang said. “As a result, while these methods are not commonly used in clinical care, the overall strategy highlights how research advances are linked to clinical advances.”

Investigators are working to secure funding for a larger phase 2 trial.

“With millions of people affected by traumatic brain injury but without effective therapies, this study brings hope that options are on the horizon to help these patients,” Dr. Yang said.

The study was supported by funding from the National Institute of Health BRAIN Initiative and a grant from the Translational Science Center at Weill Cornell Medical College. Surgical implants were provided by Medtronic. Dr. Henderson and Dr. Schiff are listed as inventors on several patent applications for the experimental DBS therapy described in the study. Dr. Cardenas and Dr. Yang report no relevant financial relationships.

Family members of veterans exposed to contaminated drinking water at Marine Corps Base Camp Lejeune, Jacksonville, North Carolina, from August 1, 1953, to December 31, 1987, are now eligible for reimbursement of health care costs associated with Parkinson disease (PD) under the Camp Lejeune Family Member Program, the US Department of Veterans Affairs (VA) has announced.

That brings the number of illnesses or conditions those family members can be reimbursed for to 16: esophageal, lung, breast, bladder, and kidney cancer, leukemia, multiple myeloma, renal toxicity, miscarriage, hepatic steatosis, female infertility, myelodysplastic syndromes, scleroderma, neurobehavioral effects, non-Hodgkin lymphoma, and Parkinson disease.

A recent JAMA study of 340,489 service members found that the risk of PD is 70% higher for veterans stationed at Camp Lejeune (n = 279) compared with veterans stationed at Camp Pendleton, California (n = 151).

The researchers say water supplies at Camp Lejeune were contaminated with several volatile organic compounds. They suggest that the risk of PD may be related to trichloroethylene exposure (TCE), a volatile organic compound widely used as a cleaning agent, in the manufacturing of some refrigerants, and found in paints and other products. In January, the US Environmental Protection Agency issued a revised risk determination saying that TCE presents an unreasonable risk to the health of workers, occupational nonusers (workers nearby but not in direct contact with this chemical), consumers, and bystanders.

Levels at Camp Lejeune were highest for TCE, with monthly median values greater than 70-fold the permissible amount.

Camp Lejeune veterans also had a significantly increased risk of prodromal PD diagnoses, including tremor, anxiety, and erectile dysfunction, and higher cumulative prodromal risk scores. No excess risk was found for other forms of neurodegenerative parkinsonism.

The PACT Act allows veterans and their families to file lawsuits for harm caused by exposure to contaminated water at Camp Lejeune. “Veterans and their families deserve no-cost health care for the conditions they developed due to the contaminated water at Camp Lejeune,” said VA’s Under Secretary for Health, Dr. Shereef Elnahal, MD. “We’re proud to add Parkinson disease to the list of conditions that are covered for veteran family members, and we implore anyone who may be living with this disease—or any of the other conditions covered by VA’s Camp Lejeune Family Member Program—to apply for assistance today.”

TOPLINE:

Heavy secondhand smoke (SHS) exposure is associated with severe headache or migraine in adults who have never smoked, with effects of exposure varying depending on body mass index (BMI) and level of physical activity, new research shows.

METHODOLOGY:

Investigators analyzed data on 4,560 participants (median age, 43 years; 60% female; 71.5% White) from the 1999-2004 National Health and Nutrition Examination Survey.

Participants were aged 20 years or older and had never smoked.

Migraine headache status was determined by asking whether participants experienced severe headaches or migraines during the previous 3 months.

SHS exposure was categorized as unexposed (serum cotinine levels <0.05 ng/mL and no smoker in the home), low (0.05 ng/mL ≤ serum cotinine level <1 ng/mL), or heavy (1 ng/mL ≤ serum cotinine level ≤ 10 ng/mL).

TAKEAWAY:

In all, 919 (20%) participants had severe headaches or migraines.

After adjustment for demographic and lifestyle factors (including medication use), heavy SHS exposure was positively associated with severe headache or migraine (adjusted odds ratio [aOR], 2.02; 95% CI, 1.19-3.43).

No significant association was found between low SHS exposure and severe headaches or migraine (aOR, 1.15; 95% CI, 0.91-1.47).

In participants who were sedentary (P=.016) and those with a BMI <25 (P=.001), significant associations between SHS and severe headache or migraine were observed.

IN PRACTICE:

Noting a linear dose-response relationship between cotinine and severe headaches or migraine, the investigators write, “These findings underscore the need for stronger regulation of tobacco exposure, particularly in homes and public places.”

SOURCE:

Junpeng Wu, MMc, and Haitang Wang, MD, of Southern Medical University in Guangzhou, China, and their colleagues conducted the study. It was published online in Headache.

LIMITATIONS:

The study could not establish causal relationships between SHS and migraine or severe headache. In addition, the half-life of serum cotinine is 15-40 hours and thus this measure can reflect only recent SHS exposure.

DISCLOSURES:

The study was not funded. The investigators reported no disclosures.

Food insecurity among older adults is associated with increased dementia risk, poorer memory function, and faster memory decline, new research indicates.

METHODOLOGY:

• Researchers analyzed data on 7,012 adults (mean age, 67 years; 59% women) from the U.S. Health and Retirement Study.
• Food security status was assessed in 2013 using a validated survey, with cognitive outcomes evaluated between 2014 and 2018.
• Analyses were adjusted for demographics, socioeconomics, and health factors.

TAKEAWAY:

• About 18% of adults were food insecure, with 10% reporting low food security and 8% very low food security. About 11% of those aged 65+ in 2013 were food insecure.
• The odds of dementia were 38% higher (odds ratio, 1.38; 95% confidence interval [CI], 1.15-1.67) in adults with low food security and 37% higher (OR, 1.37; 95% CI, 1.11-1.59) in those with very low food security, compared with food-secure adults.
• Translated to years of excess cognitive aging, food insecurity was associated with increased dementia risk equivalent to roughly 1.3 excess years of aging.
• Low and very low food security were also associated with lower memory levels and faster age-related memory decline.

IN PRACTICE:

“Our study contributes to a limited literature by capitalizing on a large and diverse sample, validated exposure and outcome measures, and longitudinal data to robustly evaluate these associations, providing evidence in support of the connection between food insecurity in older adulthood and subsequent brain health,” the authors wrote. “Our findings highlight the need to improve food security in older adults and that doing so may protect individuals from cognitive decline and dementia.”

SOURCE:

The study, with first author Haobing Qian, PhD, with the University of California, San Francisco, was published online  in JAMA Network Open.

LIMITATIONS:

Residual confounding cannot be ruled out. Food insecurity was not assessed prior to 2013. The researchers lacked information on clinical dementia diagnoses.

DISCLOSURES:

The study was supported by grants from the National Institutes of Health. The authors reported no relevant conflicts of interest.

In the first study of its kind, U.K. and French researchers reported that exercise positively affected physical and cognitive health in persons with Down syndrome. “The findings are significant and offer a crucial challenge to the [Down syndrome] and wider societies,” wrote a team led by Dan Gordon, PhD, associate professor of cardiorespiratory exercise physiology at Anglia Ruskin University in Cambridge, England. “Impact of Prescribed Exercise on the Physical and Cognitive Health of Adults with Down Syndrome: The MinDSets Study” was published in the International Journal of Environmental Research and Public Health.

“Through the simple application of walking, a form of exercise which requires little to no equipment or expense, there were significant increases in cognitive and executive function, reflecting improved capabilities in key attributes of information processing, vigilance, and selective attention,” the researchers wrote.

Dr. Gordon

“Increased cognitive function will help foster increased societal integration and quality of life, which, given that this is the first generation of those with [Down syndrome] to outlive their parents and caregivers, is of importance,” they wrote.

For example, those in an exercise-only intervention arm had an 11.4% improvement on the distance covered in the Six-Minute Walk Test, going from a mean of 498.8 meters before intervention to 522.1 meters afterward. Those in a group that combined group exercise with cognitive training increased the distance walked by 9.9%, or 49.2 meters. Groups that got cognitive training only or no intervention showed no significant changes.

In measures of cognitive function, the exercise group showed a 38% increase in selective attention, with the cognitive and combined groups showing changes for the same measure of 16.5% and 55.3%, respectively. The changes for concentration in the exercise-alone group was 31.5%, while those receiving cognitive training alone or combined exercise plus cognitive training showed improvements in concentration of 21% and 15%, respectively.

Asked why a combination intervention was not superior to exercise alone, Dr. Gordon said in an interview, “Something we’re looking at in the data but can’t fully confirm is that the combined group started to become fatigued due to the double dose of the intervention, and this prevented them in the final tests from doing quite so well as the exercise-alone group. Irrespective of the magnitude of change, any cognitive adaptation observed will be beneficial to this population.”

The evidence for the benefits of exercise on both physical and cognitive health in a non–Down syndrome population are well established, he said, but there were few data on its effect on the Down syndrome population.

One small study showed physical and neurocognitive benefits with resistance training.

“The evidence from previous studies showed increased levels of inactivity and sitting time in Down syndrome individuals compared with non–[Down syndrome] controls, so we hypothesized that exercise, albeit small amounts, would increase their physical fitness,” Dr. Gordon said.

His team also hypothesized that walking would stimulate cognitive development since it requires heightened cognitive engagement compared with inactivity. “What surprised us was the degree of improvement,” Dr. Gordon said.

The process of walking requires the brain to interpret information on a real-time basis from both internal and external cues, he continued. “For most of us this process requires low-level cognitive engagement. However, in the [Down syndrome] population, where motor control is impaired and accompanied by poor muscle tone, walking imposes a heightened cognitive load.” It requires them to concentrate on the action, be aware of their surroundings, and make the right decisions, all of which stimulate areas of the brain that control these functions.
 

Study details

Eighty-three adult participants were available for final analysis – 67 from North America, 8 from Europe, 5 from Africa, 2 from Asia, and 1 from Australia. The mean age of participants was 27.1 years, 40 were female, and all had caregiver support during the study.

Those unable to visualize information on computer and mobile/tablet screens or to listen to instructions/auditory cues were excluded. All were provided with instructions and a mobile monitoring tool set to record steps completed, distances covered, speeds, and heart rate.

Each was assigned to one of four groups. Exercise intervention-only consisted of 8 weeks of cardiorespiratory exercise defined as either walking or jogging three times a week for 30 minutes. Cognitive training included eight levels (about 20 minutes) of cognitive and executive function exercises six times per week. The combined group completed both the cardiorespiratory and cognitive interventions, while the fourth group acted as controls with no intervention.

According to the authors, the study offers a real-life scenario that can be readily adopted within the Down syndrome community.

This study was commissioned by the Canadian Down Syndrome Society. The authors had no conflicts of interest to declare.

The antiseizure drugs levetiracetam (Keppra, Keppra XR, Elepsia XR, Spritam, generic) and clobazam (Onfi, Sympazan, generic) can cause a rare but serious drug hypersensitivity reaction that can be life threatening if not detected and treated promptly, the Food and Drug Administration warns in an alert.

Known as drug reaction with eosinophilia and systemic symptoms (DRESS), it may start as a rash but can quickly progress and cause injury to internal organs, the need for hospitalization, and death, the FDA notes.

A search of the FDA Adverse Event Reporting System (FAERS) and the medical literature through March 2023 identified 32 serious cases of DRESS worldwide that were associated with levetiracetam.

Three cases occurred in the United States, and 29 occurred abroad. In all 32 cases, the patients were hospitalized and received medical treatment; in 2 cases, the patients died.

The median time to onset of DRESS in the levetiracetam cases was 24 days; times ranged from 7 to 170 days. The reported signs and symptoms included skin rash (n = 22), fever (n = 20), eosinophilia (n = 17), lymph node swelling (n = 9), and atypical lymphocytes (n = 4).

Twenty-two levetiracetam-associated cases of DRESS involved injury to one or more organs, including the liver, lungs, kidneys, and gallbladder.

In 25 of the 29 cases for which information on treatment discontinuation was available, DRESS symptoms resolved when levetiracetam was discontinued.

As for clobazam, a search of FAERS and the medical literature through July 2023 identified 10 serious cases of DRESS worldwide – 1 in the United States and 9 abroad. All 10 patients were hospitalized and received medical treatment. No deaths were reported.

The median time to onset of clobazam-associated DRESS was 21.5 days (range, 7-103 days). The reported signs and symptoms included skin rash (n = 10), fever (n = 8), eosinophilia (n = 7), facial swelling (n = 7), leukocytosis (n = 4), lymph node swelling (n = 4), and leukopenia/thrombocytopenia (n = 1).

In nine cases, there was injury to one or more organs, including the liver, kidneys, and gastrointestinal tract.

DRESS symptoms resolved in all 10 cases when treatment with clobazam was stopped. DRESS and other serious skin reactions reported with clobazam, a benzodiazepine, have not generally been associated with other benzodiazepines, the FDA notes.

Label updates

As a result of these cases, warnings about the risk of DRESS will be added to the prescribing information and patient medication guides for these medicines, the FDA announced.

“Health care professionals should be aware that prompt recognition and early treatment is important for improving DRESS outcomes and decreasing mortality,” the FDA said.

They noted that diagnosis is often difficult because early signs and symptoms, such as fever and swollen lymph nodes, may be present without evidence of a rash.

DRESS may develop 2-8 weeks after starting levetiracetam or clobazam. Symptoms and intensity can vary widely.

DRESS can also be confused with other serious skin reactions, such as Stevens-Johnson syndrome and toxic epidermal necrolysis.

The FDA says patients should be advised of the signs and symptoms of DRESS and be told to stop taking the medicine and seek immediate medical attention if DRESS is suspected during treatment with levetiracetam or clobazam.

Adverse reactions with these medications should be reported to the FDA’s MedWatch program.

TOPLINE:

An international expert consensus offers guidance to diagnose, assess, and treat adult patients experiencing drug reaction with eosinophilia and systemic symptoms (DRESS).

METHODOLOGY:

Data on the evaluation, assessment, and treatment of the rare but potentially life-threatening drug hypersensitivity reaction are lacking.

To support clinicians in diagnosing and managing DRESS, a steering committee conducted a literature review to examine current research, identify evidence, and develop consensus statements. They invited experts from 21 countries across four continents to participate in a Delphi consensus process.

An international panel of 54 experts (including 45 dermatologists) initially assessed 100 statements related to baseline workup, severity of the condition, and treatment. Two more statements were added in the second round.

After revisions and the second round, the group reached consensus for 93 statements overall.

TAKEAWAY:

The statements generating the most disagreement involved diagnosis. The group ultimately supported the value of measuring the viral load of Epstein-Barr virus, cytomegalovirus, and human herpesvirus 6 in all patients with suspected DRESS. The group also agreed on screening for hepatitis A, B, and C in cases of liver involvement and screening for hepatitis B and C before starting systemic therapy.

The group agreed with previous severity criteria that differentiate between mild, moderate, and severe DRESS based on the extent of liver, kidney, and blood involvement and the damage of other organs.

Consensus on treatment was reached for all 12 relevant statements in the first Delphi round. Recommendations included the use of corticosteroids and immediate discontinuation of the drugs causing the reaction.

IN PRACTICE:

“This Delphi exercise aimed to provide a common ground of consensus,” the authors noted. However, “each of the addressed categories needs more in-depth follow-up studies to improve the clinical management of patients.”

SOURCE:

The DRESS Delphi consensus group conducted its exercise under the leadership of Marie-Charlotte Brüggen, MD, of the University Hospital of Zürich. The consensus was published online in the JAMA Dermatology.

LIMITATIONS:

Published evidence was limited because of the low prevalence of DRESS. The consensus statements should therefore be considered with caution and in the context of a clinician’s expertise and available resources. Research gaps also persist in how DRESS may vary with region and ethnicity. The severity thresholds need validation in a revised multicenter statement.

DISCLOSURES:

The consensus review received no outside funding. Dr. Brüggen disclosed relationships with the Swiss National Science Foundation, Christine Kühne – Center for Allergy Research and Education, FreeNovation, LEO Foundation, Olga Mayenfisch Foundation, University of Zürich, LEO Pharma, Pierre Fabre Eczema Foundation, Eli Lilly, AbbVie, GSK, and AstraZeneca. Coauthors disclosed relationships with multiple pharmaceutical companies, foundations, and medical publishing companies.

The group also agreed on screening for hepatitis A, B, and C in cases of liver involvement and screening for hepatitis B and C before starting systemic therapy.

The group agreed with previous severity criteria that differentiate between mild, moderate, and severe DRESS based on the extent of liver, kidney, and blood involvement and the damage of other organs.

Consensus on treatment was reached for all 12 relevant statements in the first Delphi round. Recommendations included the use of corticosteroids and immediate discontinuation of the drugs causing the reaction.

IN PRACTICE:

“This Delphi exercise aimed to provide a common ground of consensus,” the authors noted. However, “each of the addressed categories needs more in-depth follow-up studies to improve the clinical management of patients.”

SOURCE:

The DRESS Delphi consensus group conducted its exercise under the leadership of Marie-Charlotte Brüggen, MD, of the University Hospital of Zürich. The consensus was published online in the JAMA Dermatology.

LIMITATIONS:

Published evidence was limited because of the low prevalence of DRESS. The consensus statements should therefore be considered with caution and in the context of a clinician’s expertise and available resources. Research gaps also persist in how DRESS may vary with region and ethnicity. The severity thresholds need validation in a revised multicenter statement.

DISCLOSURES:

The consensus review received no outside funding. Dr. Brüggen disclosed relationships with the Swiss National Science Foundation, Christine Kühne – Center for Allergy Research and Education, FreeNovation, LEO Foundation, Olga Mayenfisch Foundation, University of Zürich, LEO Pharma, Pierre Fabre Eczema Foundation, Eli Lilly, AbbVie, GSK, and AstraZeneca. Coauthors disclosed relationships with multiple pharmaceutical companies, foundations, and medical publishing companies.

TOPLINE:

An international expert consensus offers guidance to diagnose, assess, and treat adult patients experiencing drug reaction with eosinophilia and systemic symptoms (DRESS).

METHODOLOGY:

Data on the evaluation, assessment, and treatment of the rare but potentially life-threatening drug hypersensitivity reaction are lacking.

To support clinicians in diagnosing and managing DRESS, a steering committee conducted a literature review to examine current research, identify evidence, and develop consensus statements. They invited experts from 21 countries across four continents to participate in a Delphi consensus process.

An international panel of 54 experts (including 45 dermatologists) initially assessed 100 statements related to baseline workup, severity of the condition, and treatment. Two more statements were added in the second round.

After revisions and the second round, the group reached consensus for 93 statements overall.

TAKEAWAY:

The statements generating the most disagreement involved diagnosis. The group ultimately supported the value of measuring the viral load of Epstein-Barr virus, cytomegalovirus, and human herpesvirus 6 in all patients with suspected DRESS.

TOPLINE:

Posttraumatic stress disorder (PTSD) symptoms are associated with poorer cardiovascular and neurocognitive health among midlife women, particularly those who are APOEε4 carriers, new research suggests.

METHODOLOGY:

• Researchers conducted a cross-sectional study of 274 women (mean age, 59 years) participating in the MsBrain study of menopause and brain health.
• As part of the study, the women completed the PTSD Checklist–Civilian Version and underwent physical and neuropsychological testing, as well as carotid artery ultrasonography and brain MRI.
• Outcomes of interest were associations of PTSD symptoms with carotid intima media thickness (IMT), brain white matter hyperintensity volume (WMHV), and cognition, assessed in linear regression models.
• Interactions by APOEε4 were assessed; covariates included age, race/ethnicity, education, and CVD risk factors.

TAKEAWAY:

• Higher PTSD symptoms were associated with greater carotid IMT (P = .03); associations of PTSD symptoms with neurocognitive outcomes varied significantly by APOEε4 status.
• Among APOEε4 carriers, PTSD symptoms were associated with greater whole-brain WMHV (P = .009), periventricular WMHV (P = .02), deep WMHV (P = .01), and frontal WMHV (P = .04) in multivariable models.
• APOEε4 carriers with PTSD symptoms also had poorer cognition, specifically attention and working memory (P = .02), semantic fluency (P = .01), perceptual speed (P = .002) and processing speed (P = .002), in multivariable models.

IN PRACTICE:

“This study sheds important insight on the implications of PTSD symptoms to women’s cardiovascular and neurocognitive health. Our findings indicate that the APOEε4 genotype may identify a group of women with PTSD symptoms at particular risk for poor neurocognitive health,” the authors wrote.

SOURCE:

The study, with first author Rebecca Thurston, PhD, of the department of psychiatry, University of Pittsburgh, was published online  in JAMA Network Open.

LIMITATIONS:

No diagnostic clinical interviews were conducted, and PTSD treatment was not assessed. All participants identified as cisgender, and most were non-Hispanic Black or White. The study was observational and cross-sectional, precluding assertions about directionality or causality.

DISCLOSURES:

The study was funded by the National Institutes of Health, the University of Pittsburgh Clinical and Translational Science Institute, and the University of Pittsburgh Small Molecule Biomarker Core. Dr. Thurston reported receiving personal fees from Astellas Pharma, Bayer, Hello Therapeutics, Vira Health, and Happify Health outside the submitted work.

Adults with Parkinson’s disease are twice as likely to engage in suicidal behavior as the general population, results of a large meta-analysis show.

Given that up to half of patients with PD suffer from depression and anxiety, physicians should maintain a “high index of suspicion” for early recognition and management of suicidality, write the investigators, led by Eng-King Tan, MD, of Duke-NUS Medical School, Singapore.

“Management of both medical, such as sleep disorders, and psychosocial risk factors, such as feelings of loneliness, hopelessness, and depressed mood, could be useful in lowering suicide risk in patients with PD,” they add.

The study was published online  in JAMA Neurology.
 

Suicide risk neglected in PD?

The analysis included 505,950 patients with PD across 28 cross-sectional, case-control, and cohort studies.

Across 14 studies, the prevalence of suicidal ideation in patients with PD was 22.2% (95% confidence interval, 14.6-32.3). In a sensitivity analysis excluding three outliers, the prevalence of suicidal ideation was higher at 24% (95% CI, 19.1-29.7).

Across 21 studies, the prevalence of suicidal behavior was “substantial” at 1.25% (95% CI, 0.64-2.41), the authors report. The prevalence of suicidal behavior was significantly higher in prospective studies (1.75%; 95% CI, 1.03-2.95) than retrospective studies (0.50%; 95% CI, 0.24 to 1.01).

Across 10 studies, the likelihood of suicidal behavior was about twofold higher among patients with PD than general population controls (odds ratio, 2.15; 95% CI, 1.22-3.78; P = .01). Across nine studies, the hazard ratio for suicidal behavior was 1.73 (95% CI, 1.40-2.14; P < .001).

There was no evidence of sex-related differences in suicidal behavior, although the analysis was limited by the paucity of data, the researchers note. 

They note the quality of included studies was generally high, although eight of them did not explicitly identify and adjust for confounders.
 

Higher rate of mood, anxiety disorders

Paul Nestadt, MD, with Johns Hopkins Bloomberg School of Public Health, Baltimore, said this analysis reiterates what several reviews have found over the past few years, including his own.

“In general, rates of mood and anxiety disorders are much higher in PD than in other dementias, such as Alzheimer’s disease. This is reason enough to allocate resources to the mental health care of those diagnosed with PD and to pay special attention to at risk periods, such as early in the diagnosis, when suicide rates seem to be higher in dementias in general,” said Dr. Nestadt, who wasn’t involved in the study.

He noted that research has shown that suicides among people with PD are more likely to involve a firearm – likely because people with PD are more likely to be over age 65 and to be male – “both huge risk factors for firearm suicide.”

“Therefore, it is essential that caregivers be aware of the risks posed by firearms in the homes of people suffering from Parkinson’s or other dementias. It is the clinician’s responsibility to inform families of this risk, but it is all too often neglected,” Dr. Nestadt said.

Support for the study was provided in part by the National Medical Research Council. Dr. Tan reported honoraria from Eisai and Elsevier outside the submitted work. Dr. Nestadt reports no relevant financial relationships.

TOPLINE:

A 3-month yoga program that integrates deep breathing, meditation, and positive affirmations is associated with a significant reduction in seizure frequency, anxiety, and self-perceived feelings of stigma in people with epilepsy, a new study shows.

AlenaPaulus/E+/Getty Images

METHODOLOGY:

• Investigators included participants aged 18-60 years with epilepsy who scored ≥ 4 on the Kilifi Stigma Scale of Epilepsy. A score greater than the 66th percentile indicates the presence of strongly felt stigma.
• Patients (n = 160) had an average of one seizure per week, and most took at least two antiseizure medications.
• The intervention group (n = 80) participated in a yoga module with muscle-loosening exercises, slow and synchronized breathing, meditation, and positive affirmations. The control group (n = 80) participated in sham yoga sessions with no instructions on the breathing exercises or attention to the body movements and sensations during practice.
• Both groups participated in seven 1-hour supervised group yoga sessions over 3 months, were asked to practice the interventions at home five times per week, and received a psychoeducation module on epilepsy.

TAKEAWAY:

• Participants practicing the intervention module had significant reductions in self-perceived stigma, compared with those in the control group (P = .01).
• The proportion of participants in the intervention group who had a more than 50% seizure reduction (odds ratio, 4.11; P = .01) and complete seizure remission (OR, 7.4; P = .005) at the end of the 6-month follow-up was significantly higher than in the control group.
• Compared with those in the control group, there were also significant improvements in anxiety (P = .032) and quality of life (P < .001) in the intervention group.
• The intervention group also experienced significant improvement in mindfulness (P < .001) and cognitive impairment, compared with the control group (P < .004).

IN PRACTICE:

“This stigma can affect a person’s life in many ways, including treatment, emergency department visits, and poor mental health,” study investigator Majari Tripathi, MD, of All India Institute of Medical Sciences, New Delhi, said in a press release. “Our study showed that doing yoga can alleviate the burden of epilepsy and improve the overall quality of life by reducing this perceived stigma.”

SOURCE:

Dr. Tripathi and Kirandeep Kaur, MD, also of All India Institute of Medical Sciences, conducted the study with their colleagues. It was published online in Neurology.

LIMITATIONS:

There was no passive control or treatment as usual group, which would indicate the effect size of the intervention. In addition, there was no monitoring of seizure frequency before the study began, which may have biased the change of seizure frequency as an outcome.

DISCLOSURES:

The study investigators reported no study funding or reported disclosures.
