Psychiatric comorbidities in the pediatric neurology clinic

– Neurology and psychiatry have an inherent kinship, as one often deals with the brain and the other always focuses on the mind. The two fields can be intertwined, since neurological conditions are often associated with psychiatric comorbidities amid complex relationships: For example, a young patient with a neurological disorder may experience anxiety due to life changes, his or her diagnosis, or altered biological pathways from the condition or medications used to treat it.

As a result, psychiatric comorbidities are often seen among pediatric patients with neurological conditions, and pediatric neurologists can play an important role in diagnosis and management of such disorders, according to Devin McNulty, PhD, who spoke on the topic at the 2022 annual meeting of the Child Neurology Society.
 

The ‘second pandemic’

Mental health conditions represent about 16% of the global burden of disease among people aged 10-19, and the COVID-19 pandemic has drastically worsened the problem, as shutdowns, school loss, and economic struggles have added to the burden. “I think we’ve really seen mental health as sort of the second pandemic. We’ve seen this in Chicago in our emergency room, and in outpatient clinics wait-lists are really high. I think adolescents are specifically at risk,” said Dr. McNulty during her talk. She is an assistant professor of psychiatry and behavioral sciences at Northwestern University and a child psychiatrist at Ann & Robert H. Lurie Children’s Hospital of Chicago.

Common diagnoses include major depressive order, social anxiety disorder, generalized anxiety disorder, post-traumatic stress disorder, obsessive-compulsive disorder, somatic symptom disorder, and functional neurological symptom disorder. The last can appear as neurological symptoms that are not consistent with neurological medical conditions, such as attacks or seizures, abnormal movements, sensory loss or gain, weakness or paralysis, or speech and swallowing issues. It is the second most commonly diagnosed disorder in neurology clinics and accounts for 10% of neurology hospitalizations, and it leads to high rates of health care utilization and functional impairment.

Overall, children with neurological conditions are at about a 5-fold increased risk for depression and anxiety disorders, with a range of contributing risk factors. These include biological factors like medication use, neurological dysfunction, and genetic vulnerability. Psychological factors include stressors, the child’s reaction to the diagnosis and illness, and the level of his or her coping skills. Psychiatric comorbidities may also be triggered by social factors such as familial stress, peer rejection and social isolation, and barriers to treatment for the neurological condition. As just one example, overprotective parenting behavior, while adaptive in moderation, can create a sort of feedback loop that can lead to separation anxiety.
 

A unique opportunity

“There’s an overlap,” Dr. McNulty said, “because the origin is often multifactorial.” A young patient has a medical condition, which can be chronic or disabling, and the age of onset and diagnosis comes during a critical developmental period. “Then we have issues such as the impact of treatments, whether that’s medication side effects or medical visits. And then disease-related environmental changes, such as family factors, social changes, and impact on school,” said Dr. McNulty.

Child neurologists are in a unique position to identify and ensure treatment of these psychiatric comorbidities, according to Dr. McNulty. “Child neurologists will see psychiatric symptoms in their patient population, and pediatric providers have a unique capacity and ability to treat these patients, especially when you’re seeing patients on a frequent basis. You get to know these patients and their families really well,” she said.

She specifically pointed to three areas: psychosocial screening, differential diagnosis, and treatment and management.

There are broad-based screening measures that can be useful, such as the Strengths and Difficulties Questionnaire and the Pediatric Symptom Checklist. Disorder-specific screening tools include the PHQ-9 (depression), GAD7 (anxiety), Vanderbilt (ADHD), and PROMIS measures for anxiety and depression. “The idea behind the screening measure is that all patients would fill this out and then if a patient screens positive, they would benefit from a more thorough evaluation and history,” said Dr. McNulty.

However, she noted that screening shouldn’t necessarily be a one-off effort. Research has shown that sequential screening is the most powerful strategy. “Then you can get a baseline of a patient’s emotional and behavioral functioning, and it’s actually the changes in some of these screening measures that might give them most clinical information,” said Dr. McNulty.

In fact, on October 11, 2022, the U.S. Preventive Services Task Force announced a recommendation that all children starting at age 8 should be screened for anxiety disorders. It is already recommended to screen children aged 12 and over for depressive disorders, although these documents are aimed primarily at pediatricians or primary care clinics. The American Academy of Neurology has also recommended routine screening of psychiatric and behavioral disorders among children with epilepsy.
 

A unique perspective

Once a disorder is identified, neurologists can bring a unique perspective to treatment. The neurologist can use his or her knowledge of the disease state to assess whether symptoms are due to poor adjustment to the neurological condition, a primary psychiatric disorder, or the biological underpinnings of the illness or prescribed medications. “I think their neurologist can sort of help tease that apart, [using] their knowledge of neurologic disorders and pathways and medications in a way that psychologists might not be able to do on their own,” said Dr. McNulty.

She also emphasized that there are effective treatments for psychiatric disorders, including cognitive behavioral therapy and various pharmacotherapy options. Other approaches for treating comorbid neurological and psychiatric disorders may include building adaptive coping skills, psychoeducation, and incorporating changes to the family or school environment.

During the Q&A period, one person commented that there should be more psychiatric training for neurology residents. “We do work with the same brain, so I completely agree with that,” said Dr. McNulty.

She was also asked how to identify psychiatric symptoms in nonverbal patients. “One thing that I pay close attention to when I ask parents about (their child) is changes in their physical (attributes). Oftentimes in anxiety in folks who are not severely impaired, if we’re feeling anxious we might be breathing a little faster, or we might get a little sweaty. So looking for physical manifestations is one thing. And then sometimes I’ll tell the parents, if we’re not quite sure, I’ll say ‘I’m not sure, but this is very common given the disorder that you have. Can we check?’ I’m always very clear that I may not be nailing it, but then when we go after it with targeted treatment and we see it getting better, we can say ‘Aha!’ ”

Stroke management: There’s an app for that

In the management of acute and chronic stroke, smartphone apps enhance communication between first responders and waiting hospital staff and reduce door-to-needle time, according to a literature review.

“In clinical practice, guideline-driven patient care is very important in improving diagnosis and outcomes, and apps provide a very practical and easy way to check available guidelines,” senior author Fabio Pilato, MD, a neurologist at Università Campus Bio-Medico, Rome, told this news organization.

The review was published  in the Journal of Stroke.
 

Reviewing the literature

“My colleagues and I wanted to discover whether smartphone apps, besides just facilitating communication between doctors and their patients, could improve patient care,” said Dr. Pilato. “We wanted to see if there were any apps that could guide clinical decisions according to guidelines and whether there were some being used in acute stroke management,” he added.

The investigators reviewed 43 studies of stroke-related mobile phone apps that were designed for the clinical management of stroke between June 1, 2007, when the first iPhone was introduced, and Jan. 31, 2022.

The apps were classified into the following three groups, according to their purpose: primary prevention apps, acute stroke management apps, and postacute stroke apps.
 

Prevention and management

The investigators found one primary prevention app, the Stroke Riskometer, that was based on an algorithm derived from the Framingham Stroke Risk Score and was designed to educate patients about diet, physical activity, and the warning signs of stroke. However, their review failed to show that the app was beneficial, compared with standard cardiovascular risk reduction.

Apps appeared to aid acute stroke management, according to the researchers. Prehospital apps, such as iLAMA, Smartphone-Assisted Pre-Hospital Medical Information System, FAST-ED, Egyptian Stroke Network, Act Fast, and the Mayo Clinic Acute Stroke Evaluation app were found to speed up stroke recognition, activate emergency medical services for speedier transport to the hospital, and facilitate communication with in-hospital stroke teams. All these prehospital apps reduced door-to-needle time.

The JOIN app also was shown to significantly reduce door-to-needle time, compared with no app support, in several studies. JOIN consists of a chat, a DICOM viewer, and an encrypted two-way video system for video calls between practitioners, as well as a milestones time stamp to record every step from home to hospital transportation to therapy onset. 

StopStroke, another app that focuses on instant communication among physicians and allows real-time sharing of clinical data of stroke patients, reduced door-to-image and door-to-needle time, compared with no app.

Act Fast, which uses a National Institutes of Health Stroke Scale (NIHSS) calculator, a thrombolysis checklist, and a toolbox to share images and notes among practitioners involved in the decision-making process, decreased door-to-needle time by 16 minutes, compared with no app.

In a study of medical residents, adherence to guidelines was higher in participants who used the Mayo Clinic Acute Stroke Evaluation app, compared with those who did not. Door-to-needle time also was reduced by 16 minutes in the app-assisted group, compared with controls.
 

Postacute stroke apps

The Rehabilitation Guardian app, consisting of a health reminder, consultation, health information, and patient diary, gives medical information and provides rehabilitation exercises. Patients can enter their clinical information, and the medical staff can access it and assist with the rehab process remotely.

As for apps for chronic management and secondary prevention, Dr. Pilato and colleagues found that the PRESTRO app, which combines motivational support for a healthy lifestyle and tells patients to take their medications and measure their blood pressure, successfully got patients to be more physically active, compared with those who did not use the app.

Another app for secondary prevention, the Korea University Health Monitoring System for Stroke (KUHMS2), reduced blood pressure and glucose levels in patients who used it, compared with those who did not.

Lose It, a weight loss app, is an electronic food journal that shows the values of the macronutrients of foods that the patient consumes, as well as a daily calorie count. The Engaging Everyday Activities app effectively reminds patients who have had transient ischemic attacks about daily activities that can reduce their risk for a recurrent attack.

Movies4Stroke features educational videos about first aid, rehabilitation, how to improve swallowing, and stroke risk factors.

AFib 2gether allows patients to enter their clinical data and calculates their annual stroke risk scores. The information is provided to a health care provider before the next visit to help the patient make an informed decision about anticoagulation therapy.

“We believe that the widespread use of smartphones and apps may improve patient care in every part of the world and in particular in those parts where updated guideline consultation is not readily available. However, in our study we found that apps to implement guidelines by a clinical decision support system are still lacking. Our hope is that these apps will increase in the future,” said Dr. Pilato.
 

No panacea

Commenting on this review for this article, Amy Guzik, MD, associate professor of neurology at Wake Forest University School of Medicine, Winston-Salem, N.C., said that all physicians are looking for opportunities to use technology, especially in stroke, to diagnose and treat patients in the best way they can.

“Figuring out ways to increase efficiency and get the word out to our patients is very important to us and is probably why there are so many apps out there,” said Dr. Guzik.

“There are some ways such apps could be particularly useful. One is in remote hospitals that might not have a neurologist. Helping with the diagnosis and determining what is a bad stroke that needs to go to a higher level of medical care, or whether it is something the local hospital could take care of, would be useful,” said Dr. Guzik.

“Also helping EMS figure out which hospital to go to, or once they are on their way, being able to talk to the neurologist or neurosurgeon or the emergency room doctor and make a plan before the patient gets here, so we can expedite care when the patient arrives, is where apps can be particularly useful,” she added.

There are limitations to what apps can do, however. In the case of stroke, patients may often have important barriers that do not allow them to use apps at all, she said.

“Regardless of how they are being taken care of, a lot of our stroke patients will have problems with technology. A stroke can make texting difficult. Patients may have language difficulties, weakness, or cognitive impairment. They are relying on caregivers. All of this makes it difficult for a tech solution to be the automatic solution, unless things are done in a thoughtful way to make sure that it is appropriate for stroke patients.

“Also, there are a lot of elderly patients who may not necessarily be the most tech savvy and do not have as much digital literacy as younger patients. Another limitation to consider is that some people may not even have easy access to technology. So we must make sure that this is all done with an equity focus,” said Dr. Guzik.

The study was funded by the Associazione Nazionale fra le Imprese Assicuratrici (ANIA). Dr. Pilato and Dr. Guzik reported no relevant financial relationships.

In the management of acute and chronic stroke, smartphone apps enhance communication between first responders and waiting hospital staff and reduce door-to-needle time, according to a literature review.

“In clinical practice, guideline-driven patient care is very important in improving diagnosis and outcomes, and apps provide a very practical and easy way to check available guidelines,” senior author Fabio Pilato, MD, a neurologist at Università Campus Bio-Medico, Rome, told this news organization.

The review was published  in the Journal of Stroke.
 

Reviewing the literature

“My colleagues and I wanted to discover whether smartphone apps, besides just facilitating communication between doctors and their patients, could improve patient care,” said Dr. Pilato. “We wanted to see if there were any apps that could guide clinical decisions according to guidelines and whether there were some being used in acute stroke management,” he added.

The investigators reviewed 43 studies of stroke-related mobile phone apps that were designed for the clinical management of stroke between June 1, 2007, when the first iPhone was introduced, and Jan. 31, 2022.

The apps were classified into the following three groups, according to their purpose: primary prevention apps, acute stroke management apps, and postacute stroke apps.
 

Prevention and management

The investigators found one primary prevention app, the Stroke Riskometer, that was based on an algorithm derived from the Framingham Stroke Risk Score and was designed to educate patients about diet, physical activity, and the warning signs of stroke. However, their review failed to show that the app was beneficial, compared with standard cardiovascular risk reduction.

Apps appeared to aid acute stroke management, according to the researchers. Prehospital apps, such as iLAMA, Smartphone-Assisted Pre-Hospital Medical Information System, FAST-ED, Egyptian Stroke Network, Act Fast, and the Mayo Clinic Acute Stroke Evaluation app were found to speed up stroke recognition, activate emergency medical services for speedier transport to the hospital, and facilitate communication with in-hospital stroke teams. All these prehospital apps reduced door-to-needle time.

The JOIN app also was shown to significantly reduce door-to-needle time, compared with no app support, in several studies. JOIN consists of a chat, a DICOM viewer, and an encrypted two-way video system for video calls between practitioners, as well as a milestones time stamp to record every step from home to hospital transportation to therapy onset. 

StopStroke, another app that focuses on instant communication among physicians and allows real-time sharing of clinical data of stroke patients, reduced door-to-image and door-to-needle time, compared with no app.

Act Fast, which uses a National Institutes of Health Stroke Scale (NIHSS) calculator, a thrombolysis checklist, and a toolbox to share images and notes among practitioners involved in the decision-making process, decreased door-to-needle time by 16 minutes, compared with no app.

In a study of medical residents, adherence to guidelines was higher in participants who used the Mayo Clinic Acute Stroke Evaluation app, compared with those who did not. Door-to-needle time also was reduced by 16 minutes in the app-assisted group, compared with controls.
 

Postacute stroke apps

The Rehabilitation Guardian app, consisting of a health reminder, consultation, health information, and patient diary, gives medical information and provides rehabilitation exercises. Patients can enter their clinical information, and the medical staff can access it and assist with the rehab process remotely.

As for apps for chronic management and secondary prevention, Dr. Pilato and colleagues found that the PRESTRO app, which combines motivational support for a healthy lifestyle and tells patients to take their medications and measure their blood pressure, successfully got patients to be more physically active, compared with those who did not use the app.

Another app for secondary prevention, the Korea University Health Monitoring System for Stroke (KUHMS2), reduced blood pressure and glucose levels in patients who used it, compared with those who did not.

Lose It, a weight loss app, is an electronic food journal that shows the values of the macronutrients of foods that the patient consumes, as well as a daily calorie count. The Engaging Everyday Activities app effectively reminds patients who have had transient ischemic attacks about daily activities that can reduce their risk for a recurrent attack.

Movies4Stroke features educational videos about first aid, rehabilitation, how to improve swallowing, and stroke risk factors.

AFib 2gether allows patients to enter their clinical data and calculates their annual stroke risk scores. The information is provided to a health care provider before the next visit to help the patient make an informed decision about anticoagulation therapy.

“We believe that the widespread use of smartphones and apps may improve patient care in every part of the world and in particular in those parts where updated guideline consultation is not readily available. However, in our study we found that apps to implement guidelines by a clinical decision support system are still lacking. Our hope is that these apps will increase in the future,” said Dr. Pilato.
 

No panacea

Commenting on this review for this article, Amy Guzik, MD, associate professor of neurology at Wake Forest University School of Medicine, Winston-Salem, N.C., said that all physicians are looking for opportunities to use technology, especially in stroke, to diagnose and treat patients in the best way they can.

“Figuring out ways to increase efficiency and get the word out to our patients is very important to us and is probably why there are so many apps out there,” said Dr. Guzik.

“There are some ways such apps could be particularly useful. One is in remote hospitals that might not have a neurologist. Helping with the diagnosis and determining what is a bad stroke that needs to go to a higher level of medical care, or whether it is something the local hospital could take care of, would be useful,” said Dr. Guzik.

“Also helping EMS figure out which hospital to go to, or once they are on their way, being able to talk to the neurologist or neurosurgeon or the emergency room doctor and make a plan before the patient gets here, so we can expedite care when the patient arrives, is where apps can be particularly useful,” she added.

There are limitations to what apps can do, however. In the case of stroke, patients may often have important barriers that do not allow them to use apps at all, she said.

“Regardless of how they are being taken care of, a lot of our stroke patients will have problems with technology. A stroke can make texting difficult. Patients may have language difficulties, weakness, or cognitive impairment. They are relying on caregivers. All of this makes it difficult for a tech solution to be the automatic solution, unless things are done in a thoughtful way to make sure that it is appropriate for stroke patients.

“Also, there are a lot of elderly patients who may not necessarily be the most tech savvy and do not have as much digital literacy as younger patients. Another limitation to consider is that some people may not even have easy access to technology. So we must make sure that this is all done with an equity focus,” said Dr. Guzik.

The study was funded by the Associazione Nazionale fra le Imprese Assicuratrici (ANIA). Dr. Pilato and Dr. Guzik reported no relevant financial relationships.

Diazepam nasal spray effective in Lennox-Gastaut syndrome

Tue, 10/25/2022 - 08:09

 

– A new analysis of data from a phase 3 clinical trial suggests that an inhaled diazepam nasal spray (Valtoco, Neurelis Inc.) works about as well among patients with Lennox-Gastaut Syndrome (LGS) as it does with other patients with pediatric encephalopathies.

LGS is a severe form of epilepsy that generally begins in early childhood and has a poor prognosis and seizures that are often treatment refractory. The findings of the analysis should be encouraging to physicians who may view patients with LGS as not benefiting from treatment, said Daniel C. Tarquinio, DO, who presented the results at the 2022 annual meeting of the Child Neurology Society.

“Their response to their first appropriate weight-based rescue dose of Valtoco was essentially no different. They were subtly different, but they’re not really meaningful differences. Very few needed a second dose. In practice this is helpful because we know that kids with LGS, we think of them as having worse epilepsy, if you will. But if they need rescue, if we prescribe an appropriate rescue dose based on their weight, that the same rescue will work for them as it will for a kid that doesn’t have – quote unquote – as bad epilepsy that needs rescue,” said Dr. Tarquinio, a child neurologist and epileptologist and founder of the Center for Rare Neurological Diseases.

During the Q&A, Dr. Tarquinio was asked if there is something about the biology of LGS that would suggest it might respond differently to the drug. Dr. Tarquinio said no. “The reason we even looked at this is because many clinicians told us that their sense was [that patients with LGS] did not respond as well to rescue in general no matter what they use. This allowed us to go back and look at a controlled data set and say, at least in our controlled dataset, they respond the same,” he said.

Grace Gombolay, MD, who moderated the session, agreed that the results should be encouraging. “It seems like a lot of clinicians have the sense that Lennox-Gastaut Syndrome is a very terrible refractory epilepsy syndrome, and so doing rescue doesn’t seem to make sense if they don’t really respond. I think it’s helpful to know because there are actually studies showing that Valtoco seems to actually work in those patients, so it’s actually useful clinically to prescribe those patients and give it a shot,” said Dr. Gombolay, director of the Pediatric Neuroimmunology and Multiple Sclerosis Clinic at Emory University, Atlanta.

LGS patients may experience hundreds of seizures per day. “It’s really hard for parents to quantify, did they get better? Did the rescue help or not, because they’re still having some seizures. I think the sense is, ‘oh, this isn’t working.’ That’s probably the bias. I think this is good data that if you are able to get Valtoco for your patients, I think it’s worth a shot even in Lennox-Gastaut,” said Dr. Gombolay.

The researchers conducted a post hoc analysis of the phase 3, open-label, repeat-dose safety study of Valtoco. The study included a 12-month treatment period with visits at day 30 and every 60 days following. Patients had the option of staying on the drug following the end of the treatment period. Seizure and dosing information were obtained from a diary. The study enrolled 163 patients whose physicians believed they would need to be treated with a benzodiazepine at least once every other month to achieve seizure control. Dosing was determined by a combination of age and weight. If a second dose was required, caregivers were instructed to provide it 4-12 hours after the first dose.

In the study cohort, 47.9% of patients were aged 6-17 years. The researchers looked specifically at 73 cases of seizure clusters. In nine cases, the patient had LGS (five male, four female). Nearly all (95.9%) of LGS cluster cases were treated with a single dose and 4.1% were exposed to a second dose. Among 64 cases involving a patient with pediatric epileptic encephalopathies, 89.4% were treated with a single dose and 10.6% received a second. The safety profile was similar between patients with LGS and those with pediatric encephalopathies.

Dr. Gombolay has no relevant financial disclosures.

Less than 6 hours of sleep a night linked to serious, chronic illness

Individuals who are middle-aged and older and who sleep 5 hours or less a night may be at risk for an array of serious and chronic health conditions, ranging from heart disease to cancer, results of a large study show.

Researchers at University College London and Université Paris Cité found that beginning at age 50, those who slept 5 hours or fewer a night had a 30% higher risk of developing multiple chronic diseases over time than those who slept at least 7 hours a night. By the time the participants were aged 70 years, that risk had increased to 40%.

Diseases for which there was a higher risk included diabetes, cancer, coronary heart diseasestrokeheart failurechronic obstructive pulmonary diseasechronic kidney disease, liver disease, depression, dementia, Parkinson’s disease, and arthritis.

“It is important to take care of our sleep,” lead investigator Séverine Sabia, PhD, said in an interview. Dr. Sabia is a researcher and epidemiologist at Université Paris Cité and INSERM in Paris, and the University College London.

She noted that the source of the sleep problem must be addressed, but in cases in which there is no medical reason for sleep paucity, “healthy sleep habits are a must. These include keeping a regular sleep schedule, a healthy lifestyle – physical activity and light exposure during the day, and a light dinner – and avoidance of screens for a half hour before sleep.”

The study was published online in PLOS Medicine.
 

Risk of multiple chronic diseases

Prior research suggests that sleeping for 5 hours or less or 9 hours or more is associated with cancer and cardiovascular disease (CVD).

For the current study, Dr. Sabia and her team asked nearly 8,000 civil servants in the United Kingdom as part of the Whitehall II cohort study to report the amount of sleep they received beginning at age 50 every 4 to 5 years for the next 25 years. Study participants were free of chronic disease at age 50 and were mostly male (67.5%) and White (90%).

The investigators found that at age 50, those who slept 5 hours or less were 30% more likely to be diagnosed with multiple chronic diseases over time, (hazard ratio, 1.30; 95% confidence interval, 1.12-1.50; P < .001) compared with their peers who slept 7 hours.

At age 60, those who slept 5 hours or less had a 32% greater risk of developing more than one chronic disease (HR, 1.32; 95% CI, 1.13-1.55; P < .001), and by age 70, this risk increased to 40% compared with their peers who slept 7 hours a night (HR, 1.40; 95% CI, 1.16-1.68; P < .001).

For participants who slept 9 or more hours per night, only those aged 60 (HR, 1.54; 95% CI, 1.15-2.06; P = .003) and 70 (HR, 1.51; 95% CI, 1.10-2.08; P = .010) were at increased risk of developing more than one chronic disease.

Dr. Sabia noted that previous studies have shown that those who slept less than 5 hours a night were more likely to develop diabetes, hypertension, CVD, or dementia. “However, chronic diseases often coexist, particularly at older ages, and it remains unclear how sleep duration may be associated with risk of multimorbidity,” she said. She noted that several biological hypotheses have been proposed as underlying the association.

“Sleep is important for the regulation of several body functions, such as metabolic, endocrine, and inflammatory regulation over the day, that in turn, when dysregulated, may contribute to increased risk of several chronic conditions.”

The authors acknowledge several study limitations, including the fact that the data were obtained via participant self-reports, which may be affected by reporting bias. There was also a lack of diversity within the study sample, as the civil servants were mostly male and White. In addition to this, the investigators note that the study population of British civil servants tended to be healthier than the general population.
 

 

 

Chicken or egg?

Commenting on the findings for this article, Charlene Gamaldo, MD, urged caution in interpreting the findings. She noted that self-reporting of sleep has been established as “potentially problematic” because it doesn’t always correlate with actual sleep.

Dr. Gamaldo, who is professor of neurology and psychiatry at Johns Hopkins University in Baltimore and the medical director of the JHU Center for Sleep and Wellness, said previous studies have shown that underestimation of sleep can occur among those suffering with insomnia and that overestimation can be seen among individuals with behaviorally based chronic, insufficient sleep.

Dr. Gamaldo also raised the issue of sleep quality.

“Getting 5 hours of high-quality sleep is less worrisome than one getting 8 hours of terrible-quality, based on untreated sleep apnea, for instance,” she noted.

In addition, she pointed out that chronic health problems can interrupt sleep. “Which is the chicken, and which is the egg?” she asked.

“For me, the take-home of current literature and supported by this paper is that individuals with sleep quality complaints, short duration, or related impact in daytime function should address them with their treating provider to assess for the underlying cause.

“Those sleeping under 5 hours without complaints should consider whether 5 hours really represents the amount of sleep they need to wake rested and function at their best. If answer is no, they should prioritize getting more sleep,” she concluded.

The study was funded by the National Institute on Aging, the National Institute of Health, the UK Research Medical Council, the British Heart Foundation, the Wellcome Trust, and the French National Research Agency. The investigators and Dr. Gamaldo report no relevant financial relationships.

Prior research suggests that sleeping for 5 hours or less or 9 hours or more is associated with cancer and cardiovascular disease (CVD).

For the current study, Dr. Sabia and her team asked nearly 8,000 civil servants in the United Kingdom as part of the Whitehall II cohort study to report the amount of sleep they received beginning at age 50 every 4 to 5 years for the next 25 years. Study participants were free of chronic disease at age 50 and were mostly male (67.5%) and White (90%).

The investigators found that at age 50, those who slept 5 hours or less were 30% more likely to be diagnosed with multiple chronic diseases over time, (hazard ratio, 1.30; 95% confidence interval, 1.12-1.50; P < .001) compared with their peers who slept 7 hours.

At age 60, those who slept 5 hours or less had a 32% greater risk of developing more than one chronic disease (HR, 1.32; 95% CI, 1.13-1.55; P < .001), and by age 70, this risk increased to 40% compared with their peers who slept 7 hours a night (HR, 1.40; 95% CI, 1.16-1.68; P < .001).

For participants who slept 9 or more hours per night, only those aged 60 (HR, 1.54; 95% CI, 1.15-2.06; P = .003) and 70 (HR, 1.51; 95% CI, 1.10-2.08; P = .010) were at increased risk of developing more than one chronic disease.

Dr. Sabia noted that previous studies have shown that those who slept less than 5 hours a night were more likely to develop diabetes, hypertension, CVD, or dementia. “However, chronic diseases often coexist, particularly at older ages, and it remains unclear how sleep duration may be associated with risk of multimorbidity,” she said. She noted that several biological hypotheses have been proposed as underlying the association.

“Sleep is important for the regulation of several body functions, such as metabolic, endocrine, and inflammatory regulation over the day, that in turn, when dysregulated, may contribute to increased risk of several chronic conditions.”

The authors acknowledge several study limitations, including the fact that the data were obtained via participant self-reports, which may be affected by reporting bias. There was also a lack of diversity within the study sample, as the civil servants were mostly male and White. In addition to this, the investigators note that the study population of British civil servants tended to be healthier than the general population.
 

 

 

Chicken or egg?

Commenting on the findings for this article, Charlene Gamaldo, MD, urged caution in interpreting the findings. She noted that self-reporting of sleep has been established as “potentially problematic” because it doesn’t always correlate with actual sleep.

Dr. Gamaldo, who is professor of neurology and psychiatry at Johns Hopkins University in Baltimore and the medical director of the JHU Center for Sleep and Wellness, said previous studies have shown that underestimation of sleep can occur among those suffering with insomnia and that overestimation can be seen among individuals with behaviorally based chronic, insufficient sleep.

Dr. Gamaldo also raised the issue of sleep quality.

“Getting 5 hours of high-quality sleep is less worrisome than one getting 8 hours of terrible-quality, based on untreated sleep apnea, for instance,” she noted.

In addition, she pointed out that chronic health problems can interrupt sleep. “Which is the chicken, and which is the egg?” she asked.

“For me, the take-home of current literature and supported by this paper is that individuals with sleep quality complaints, short duration, or related impact in daytime function should address them with their treating provider to assess for the underlying cause.

“Those sleeping under 5 hours without complaints should consider whether 5 hours really represents the amount of sleep they need to wake rested and function at their best. If answer is no, they should prioritize getting more sleep,” she concluded.

The study was funded by the National Institute on Aging, the National Institute of Health, the UK Research Medical Council, the British Heart Foundation, the Wellcome Trust, and the French National Research Agency. The investigators and Dr. Gamaldo report no relevant financial relationships.

Cognition-boosting ‘smart drugs’ not so smart for healthy people

Article Type
Changed
Tue, 11/01/2022 - 14:46

 

Prescription drugs designed to boost cognition in neurodevelopmental disorders do not increase overall cognitive performance in healthy individuals – and may even reduce productivity, new research suggests.

In a randomized controlled trial, 40 healthy adults were given the attention-deficit/hyperactivity disorder (ADHD) treatments methylphenidate or dexamphetamine or the wakefulness-promoting drug modafinil vs. placebo.

While receiving the so-called “smart drugs,” participants spent more time and made more moves more quickly while solving each problem on a complex cognitive task than when given the placebo. But with no significant improvement in overall performance, all drugs were associated with a significant reduction in efficiency.

The findings “reinforce the idea that, while the drugs administered were motivational, the resulting increase in effort came at a cost in the loss of productivity,” said study presenter David Coghill, MD, PhD, chair of developmental mental health, the University of Melbourne.

This was especially true for individuals who scored high when receiving placebo, “who ended up producing below average productivity when on the drugs,” he noted.

“Overall, these drugs don’t increase the performance. Instead, they cause a regression to the mean, and appear to have a more negative effect on those who performed best at baseline,” Dr. Coghill added.

He presented the findings at the 35th European College of Neuropsychopharmacology (ECNP) Congress.
 

Past evidence ambiguous

Dr. Coghill noted that prescription-only stimulant drugs are increasingly used by employees and students as “smart drugs” to enhance workplace or academic productivity.

He conducted the study with colleagues from the department of economics at his institution, because of “their interest in people using cognitive enhancers within the financial industry, in the hope that that would increase their productivity in what is a very competitive industry on the floor of the trading rooms.”

However, while “there’s a subjective belief” that these drugs are effective as cognitive enhancers, the evidence to actually demonstrate that in healthy individuals “is, at best, ambiguous,” he told meeting attendees.

Improvements in cognitive capacities, such as working memory and improved planning, are most evident in clinical populations such as those with ADHD, which could be due to a “ceiling effect” of the cognitive tasks in healthy individuals, Dr. Coghill noted.

To investigate further, the researchers conducted a randomized, double-blinded trial of standard adult doses of methylphenidate (30 mg), dexamphetamine (15 mg), and modafinil (200 mg) vs. placebo. The healthy participants (n = 40), all of whom were aged 18-35 years, crossed to each of the other treatment groups over the course of four intervention sessions.

All were asked to solve eight instances of the knapsack task, the aim of which is to place theoretical objects in a knapsack to achieve the maximum value within a certain weight limit.

“This looks very simple but as the number of items increases, it becomes incredibly complex to compute, and actually is not computable using standard approaches. You have to deal with trial and error,” Dr. Coghill said.

The participants also completed several CANTAB cognitive tasks.

 

 

‘Surprising’ findings

Results showed that, overall, the drugs did not have a significant effect on task performance (slope = –0.16; P = .011).

Moreover, the drugs, both individually and collectively, had a significant negative effect on the value attained during any one attempt at the knapsack task (slope = –0.003; P = .02), an effect that extended “across the whole range” of task complexity, Dr. Coghill reported.

He went on to show that “participants actually looked as if they were working harder” when they took the three active drugs than when they were given a placebo. They also “spent more time solving each problem,” he added.

When taking the active drugs, participants made more moves during each task than when taking placebo, and made their moves more quickly.

“So these medications increased motivation,” Dr. Coghill said. “If you were sitting [and] watching this person, you would think that they were working harder.”

Yet their productivity, defined as the average gain in value per move on the knapsack task, was lower. Regression analysis identified a “significant and sizable drop in productivity” vs. placebo, Dr. Coghill noted.

This was the case for methylphenidate (P < .001), dexamphetamine (P < .001), and modafinil (P < .05), “whether you looked at the mean or median performance,” he said.

“Breaking it down a little bit more, when you looked at the individual participant level, you find substantial heterogeneity across participants,” noted Dr. Coghill.

“More than that, we found a significant negative correlation between productivity under methylphenidate compared to productivity under placebo, and this suggests a regression to the mean,” with participants who performed better under placebo performing worse with methylphenidate, he explained.

While the relationship was “exactly the same with modafinil,” it was not found with dexamphetamine, with a strong negative correlation between the productivity effects between dexamphetamine and methylphenidate (slope = –0.29; P < .0001).

“This is surprising because we assume that methylphenidate and dexamphetamine are working in very similar ways,” Dr. Coghill said.
 

Time to rethink, rewind?

Commenting for this article, session chair John F. Cryan, PhD, department of anatomy and neuroscience, University College Cork, Ireland, said that, based on the current data, “we might need to rethink [how] ‘smart’ psychopharmacological agents are.”

Dr. Cryan, chair of the ECNP Scientific Program Committee, added that there may be a need to revisit the difficulty of different types of cognitive tasks used in studies assessing the abilities of cognitive enhancing drugs and to “rewind conventional wisdom” around them.

Also commenting, Andrew Westbrook, PhD, of the department of cognitive linguistics and psychological sciences, Brown University, Providence, R.I., said the results seem “reasonable” and are “consistent with my own perspective.”

However, he told this news organization, “some caveats are warranted,” not least that the context of the task can have an impact on the results it obtains.

“We have hypothesized that pharmacologically-enhanced striatal dopamine signaling can boost a kind of cognitive impulsivity, leading to errors and diminished performance, especially for people who already have high striatal dopamine functioning.”

He added that this impulsivity can also lead to errors “in situations where there are highly likely actions, thoughts, or behaviors” in a task, “which they would have to override to be successful” in performing it.

Dr. Westbrook gave the example of the “Stroop task where you are presented with words presented in some color ink and your job is to name the color of the ink but not read the word.”

If the word “green,” for example, was presented in green ink, “you may have no trouble naming the ink color,” but if it was presented in red ink “then you may impulsively read the word, because that is what we normally do with words. 

“Overriding this kind of habitual action can be particularly slippery business when striatal dopamine signaling is pharmacologically enhanced,” Dr. Westbrook said.

No funding for the study was reported. Dr. Coghill reported relationships with Medice, Novartis, Servier, Takeda/Shire Cambridge University Press, and Oxford University Press.

Risk score refines TIA management for PCPs, emergency docs

Article Type
Changed
Thu, 12/15/2022 - 15:36

The authors of a new evidence review recommend the Canadian TIA Risk Score for managing patients who present to the emergency department or physician’s office with an apparent transient ischemic attack (TIA) or minor stroke.

“Many hospitals do not have enough stroke neurologists to see every patient with TIA or minor stroke within 24 hours. Likewise, many emergency departments around the world are stretched beyond capacity,” study author Jeffery J. Perry, MD, senior scientist at the Ottawa Hospital Research Institute, said in an interview.

“This review corresponds to most of the recommendations by the American Heart Association and the Canadian Stroke Best Practice Recommendations,” he said. “It does, however, go further to differentiate high-risk versus low-risk patients for subsequent stroke using the Canadian TIA Score and offers practical suggestions for how to provide high-quality care in environments without the capacity to provide immediate vascular imaging, immediate MRI scanning, and immediate stroke specialist assessments.”

Most patients at low risk of a subsequent stroke (that is, patients with < 1% risk for a subsequent stroke at 7 days) can be managed safely as outpatients without causing delays in their departure for vascular imaging or neurology consultation during their initial emergency department visits, Dr. Perry added. “The Canadian TIA Score can be used to determine the urgency for an assessment by a stroke neurologist.”

The study was published  in CMAJ.
 

Score stratifies risk

Dr. Perry, lead author of the Canadian TIA Score validation study, said that the CMAJ editorial board approached him to write the review and to incorporate the new score into the latest recommendations. To include the latest evidence, Dr. Perry and colleagues reviewed the most recent position statements on TIA and minor stroke management and searched the literature for relevant articles. They note that the nomenclature related to TIA and minor stroke is inconsistent, that it’s not necessary to differentiate between the two from a clinical standpoint, and that the term “acute ischemic cerebrovascular syndrome” has been proposed to include both.

Broadly, the team’s recommended strategy for the diagnosis and management of the condition includes the following steps:

  • Diagnosis: Sudden loss of motor function and impaired speech are strong indicators; symptoms tend to be negative (for example, loss of vision rather than flashing lights).
  • Risk assessment: Use of the Canadian TIA Score to stratify 7-day stroke risk (low risk: < 1%, medium risk: 1%-5%, high risk: > 5%).
  • Investigations: Urgent CT within 48 hours; vascular imaging to identify acutely symptomatic carotid stenosis in medium- to high-risk patients, as determined on the basis of the TIA score; ECG to identify atrial fibrillation or flutter and to optimize anticoagulant use; if the index of suspicion is high, echocardiography should be employed to look for cardioembolic sources.
  • Management: Dual antiplatelet therapy for 21 days in medium- and high-risk patients; hypertension should be managed; patients should be referred for stroke clinic assessment; aggressive lifestyle changes should be initiated to lower lipid levels.

“I believe that our recommendations should be incorporated with the clinical guidelines,” said Dr. Perry.
 

Caveats and concerns

 

 

Commenting on the article, Steven M. Greenberg, MD, PhD, vice chair for faculty development of the department of neurology at Massachusetts General Hospital and a professor of neurology at Harvard Medical School, both in Boston, said, “Although the proposed guidelines are broadly evidence-based and consistent with standard of care, there are several areas where stroke specialists might disagree and suggest alternative strategies.” Dr. Greenberg was not involved in the study.

While some lower-risk features, such as repetitive or stereotyped symptoms or vertigo, can be more suggestive of TIA mimics, he said that “these features need to be scrutinized quite carefully. Critical carotid stenosis, for example, can give rise to brief, repetitive, stereotyped low-flow TIAs that require urgent revascularization.”

Vertigo might be a feature of brainstem or cerebellar TIA or minor stroke, said Dr. Greenberg, especially in the setting of other posterior circulation symptoms. Validated guidelines for differentiating peripheral vertigo and CNS vertigo are available, he noted.

“Another caveat is that the studies demonstrating benefit of brief dual antiplatelet therapy following acute TIA or minor stroke were based on ABCD2 rather than the Canadian TIA score,” he said. “It is therefore important for any score-based recommendations to be applied in the overall context of existing stroke prevention guidelines.”

In addition to the recommendation for urgent vascular imaging of patients whose presentations suggest bona fide TIA or minor stroke, most guidelines also recommend extended cardiac monitoring and transthoracic ECG to identify potential sources of embolism, Dr. Greenberg added. “Users of these guidelines should also be aware of the limited yield of head CT, which is able to detect some old strokes, large acute strokes – presumably not relevant to patients presenting with TIA or minor stroke – and acute intracranial hemorrhages.”

Louis R. Caplan, MD, founder of the Harvard Stroke Registry at Beth Israel Deaconess Medical Center, Boston, and a professor of neurology at Harvard Medical School, also commented on the study.

While the review “is okay for care by nonstroke specialists, ideally, major referral centers could have a TIA or stroke clinic, as is present in much of Western Europe,” he said. This would allow the stroke etiology to be investigated for each patient.

“Many patients can be treated with the regimen outlined by the authors, but some with other conditions, such as atrial cardiopathy, patent foramen ovale, atrial myxoma, thrombus within the cardiac ventricle or atrium, will require anticoagulants,” he noted. “Thrombolysis and mechanical thrombectomy would be considered in some. Each stroke patient is different, and management cannot be homogenized into one remedy. One size does not fit all.”

In an accompanying commentary, Shelagh B. Coutts, MD, and Michael D. Hill, MD, both of the University of Calgary (Alta.), presented their team’s approach to the acute management of patients with likely cerebral ischemia. Such management includes risk assessment and stratification by clinical symptoms, rather than a particular score. They also typically conduct CT angiography. “If the CTA is completely normal (that is, no occlusion, no atherosclerosis or arterial dissection and no other vascular abnormality), we rely on the high negative predictive value of this result and discharge the patient home on antiplatelet treatment with outpatient follow-up, including MRI of the brain (since CT cannot reliably rule out minor ischemia) within the first week,” they write.

The review was conducted without commercial funding. Dr. Perry, Dr. Greenberg, Dr. Caplan, Dr. Coutts, and Dr. Hill have disclosed no relevant financial relationships.

Most patients at low risk of a subsequent stroke (that is, patients with < 1% risk for a subsequent stroke at 7 days) can be managed safely as outpatients without causing delays in their departure for vascular imaging or neurology consultation during their initial emergency department visits, Dr. Perry added. “The Canadian TIA Score can be used to determine the urgency for an assessment by a stroke neurologist.”

The study was published  in CMAJ.
 

Score stratifies risk

Dr. Perry, lead author of the Canadian TIA Score validation study, said that the CMAJ editorial board approached him to write the review and to incorporate the new score into the latest recommendations. To include the latest evidence, Dr. Perry and colleagues reviewed the most recent position statements on TIA and minor stroke management and searched the literature for relevant articles. They note that the nomenclature related to TIA and minor stroke is inconsistent, that it’s not necessary to differentiate between the two from a clinical standpoint, and that the term “acute ischemic cerebrovascular syndrome” has been proposed to include both.

Broadly, the team’s recommended strategy for the diagnosis and management of the condition includes the following steps:

  • Diagnosis: Sudden loss of motor function and impaired speech are strong indicators; symptoms tend to be negative (for example, loss of vision rather than flashing lights).
  • Risk assessment: Use of the Canadian TIA Score to stratify 7-day stroke risk (low risk: < 1%, medium risk: 1%-5%, high risk: > 5%).
  • Investigations: Urgent CT within 48 hours; vascular imaging to identify acutely symptomatic carotid stenosis in medium- to high-risk patients, as determined on the basis of the TIA score; ECG to identify atrial fibrillation or flutter and to optimize anticoagulant use; if the index of suspicion is high, echocardiography should be employed to look for cardioembolic sources.
  • Management: Dual antiplatelet therapy for 21 days in medium- and high-risk patients; hypertension should be managed; patients should be referred for stroke clinic assessment; aggressive lifestyle changes should be initiated to lower lipid levels.

“I believe that our recommendations should be incorporated with the clinical guidelines,” said Dr. Perry.
 

Caveats and concerns

 

 

Commenting on the article, Steven M. Greenberg, MD, PhD, vice chair for faculty development of the department of neurology at Massachusetts General Hospital and a professor of neurology at Harvard Medical School, both in Boston, said, “Although the proposed guidelines are broadly evidence-based and consistent with standard of care, there are several areas where stroke specialists might disagree and suggest alternative strategies.” Dr. Greenberg was not involved in the study.

While some lower-risk features, such as repetitive or stereotyped symptoms or vertigo, can be more suggestive of TIA mimics, he said that “these features need to be scrutinized quite carefully. Critical carotid stenosis, for example, can give rise to brief, repetitive, stereotyped low-flow TIAs that require urgent revascularization.”

Vertigo might be a feature of brainstem or cerebellar TIA or minor stroke, said Dr. Greenberg, especially in the setting of other posterior circulation symptoms. Validated guidelines for differentiating peripheral vertigo and CNS vertigo are available, he noted.

“Another caveat is that the studies demonstrating benefit of brief dual antiplatelet therapy following acute TIA or minor stroke were based on ABCD2 rather than the Canadian TIA score,” he said. “It is therefore important for any score-based recommendations to be applied in the overall context of existing stroke prevention guidelines.”

In addition to the recommendation for urgent vascular imaging of patients whose presentations suggest bona fide TIA or minor stroke, most guidelines also recommend extended cardiac monitoring and transthoracic ECG to identify potential sources of embolism, Dr. Greenberg added. “Users of these guidelines should also be aware of the limited yield of head CT, which is able to detect some old strokes, large acute strokes – presumably not relevant to patients presenting with TIA or minor stroke – and acute intracranial hemorrhages.”

Louis R. Caplan, MD, founder of the Harvard Stroke Registry at Beth Israel Deaconess Medical Center, Boston, and a professor of neurology at Harvard Medical School, also commented on the study.

While the review “is okay for care by nonstroke specialists, ideally, major referral centers could have a TIA or stroke clinic, as is present in much of Western Europe,” he said. This would allow the stroke etiology to be investigated for each patient.

“Many patients can be treated with the regimen outlined by the authors, but some with other conditions, such as atrial cardiopathy, patent foramen ovale, atrial myxoma, thrombus within the cardiac ventricle or atrium, will require anticoagulants,” he noted. “Thrombolysis and mechanical thrombectomy would be considered in some. Each stroke patient is different, and management cannot be homogenized into one remedy. One size does not fit all.”

In an accompanying commentary, Shelagh B. Coutts, MD, and Michael D. Hill, MD, both of the University of Calgary (Alta.), presented their team’s approach to the acute management of patients with likely cerebral ischemia. Such management includes risk assessment and stratification by clinical symptoms, rather than a particular score. They also typically conduct CT angiography. “If the CTA is completely normal (that is, no occlusion, no atherosclerosis or arterial dissection and no other vascular abnormality), we rely on the high negative predictive value of this result and discharge the patient home on antiplatelet treatment with outpatient follow-up, including MRI of the brain (since CT cannot reliably rule out minor ischemia) within the first week,” they write.

The review was conducted without commercial funding. Dr. Perry, Dr. Greenberg, Dr. Caplan, Dr. Coutts, and Dr. Hill have disclosed no relevant financial relationships.

The authors of a new evidence review recommend the Canadian TIA Risk Score for managing patients who present to the emergency department or physician’s office with an apparent transient ischemic attack (TIA) or minor stroke.

“Many hospitals do not have enough stroke neurologists to see every patient with TIA or minor stroke within 24 hours. Likewise, many emergency departments around the world are stretched beyond capacity,” study author Jeffery J. Perry, MD, senior scientist at the Ottawa Hospital Research Institute, said in an interview.

“This review corresponds to most of the recommendations by the American Heart Association and the Canadian Stroke Best Practice Recommendations,” he said. “It does, however, go further to differentiate high-risk versus low-risk patients for subsequent stroke using the Canadian TIA Score and offers practical suggestions for how to provide high-quality care in environments without the capacity to provide immediate vascular imaging, immediate MRI scanning, and immediate stroke specialist assessments.”

In epilepsy, heart issues linked to longer disease duration

Article Type

Tue, 11/22/2022 - 11:13

 

Pediatric patients with epilepsy have an increased risk of cardiovascular complications later in life, but little is known about how they progress. A new study finds that abnormalities in electrocardiograms are linked to an earlier age of diagnosis and longer epilepsy duration.

The findings could help researchers in the search for biomarkers that could predict later problems in children with epilepsy. “In pediatric neurology I think we’re a little bit removed from some of the cardiovascular complications that can happen within epilepsy, but cardiovascular complications are well established, especially in adults that have epilepsy. Adults with epilepsy are more likely to have coronary artery disease, atherosclerosis, arrhythmias, heart attacks, and sudden cardiac death. It’s a pretty substantial difference compared with their nonepileptic peers. So knowing that, the big question is, how do these changes develop, and how do we really counsel our patients in regards to these complications?” said Brittnie Bartlett, MD, during her presentation of the research at the 2022 annual meeting of the Child Neurology Society.

Identifying factors that increase cardiac complications

Previous studies suggested that epilepsy duration might be linked to cardiovascular complications. In children with Dravet syndrome, epilepsy duration has been shown to be associated with cardiac complications. Pathological T wave alternans, which indicates ventricular instability, has been observed in adults with longstanding epilepsy but not adults with newly diagnosed epilepsy.

“So our question in this preliminary report of our data is: What factors in our general pediatric epilepsy cohort can we identify that put them at a greater risk for having EKG changes, and specifically, we wanted to verify these findings from the other studies that epilepsy duration is, in fact, a risk factor for these EKG changes in general [among children] with epilepsy aside from channelopathies,” said Dr. Bartlett, who is an assistant professor at Baylor College of Medicine and a child neurologist at Texas Children’s Hospital, both in Houston.

She presented a striking finding that cardiovascular changes appear early. “The most important thing I want you all to make note of is the fact that, in this baseline study that we got on these kids, 47% already had changes that we were seeing on their EKGs,” said Dr. Bartlett.

The researchers also looked for factors associated with EKG changes, and found that duration of epilepsy and age at diagnosis were the two salient factors. “Our kids that did have EKG changes present had an average epilepsy duration of 73 months, as opposed to [the children] that did not have EKG changes and had an average epilepsy duration of 46 months,” said Dr. Bartlett.

Other factors, such epilepsy type, etiology, refractory epilepsy, and seizure frequency had no statistically significant association with EKG changes. They also saw no associations with high-risk seizure medications, even though some antiseizure drugs have been shown to be linked to EKG changes.

“We were able to confirm our hypothesis that EKG changes were more prevalent with longer duration of epilepsy. Unfortunately, we weren’t able to find any other clues that would help us counsel our patients, but this is part of a longitudinal prospective study that we’ll be following these kids over a couple of years’ time, so maybe we’ll be able to tease out some of these differences. Ideally, we’d be able to find some kind of a biomarker for future cardiovascular complications, and right now we’re working with some multivariable models to verify some of these findings,” said Dr. Bartlett.

 

 

Implications for clinical practice

During the Q&A, Dr. Bartlett was asked if all kids with epilepsy should undergo an EKG. She recommended against it for now. “At this point, I don’t think we have enough clear data to support getting an EKG on every kid with epilepsy. I do think it’s good practice to do them on all kids with channelopathies. As a general practice, I tend to have a low threshold towards many kids with epilepsy, but a lot of these cardiovascular risk factors tend to pop up more in adulthood, so it’s more preventative,” she said.

Grace Gombolay, MD, who moderated the session where the poster was presented, was asked for comment on the study. “What’s surprising about it is that up to half of patients actually had EKG changes, different what from what we see in normal population, and it’s interesting to think about the implications. One of the things that our epilepsy patients are at risk for is SUDEP – sudden, unexplained death in epilepsy. It’s interesting to think about what these EKG changes mean for clinical care. I think it’s too early to say at this time, but this might be one of those markers for SUDEP,” said Dr. Gombolay, who is an assistant professor at Emory University, Atlanta, and director of the Pediatric Neuroimmunology and Multiple Sclerosis Clinic at Children’s Healthcare of Atlanta.

The researchers prospectively studied 213 patients who were recruited. 46% were female, 42% were white, 41% were Hispanic, and 13% were African American. The mean age at enrollment was 116 months, and mean age of seizure onset was 45 months.

The researchers found that 47% had abnormal EKG readings. None of the changes were pathologic, but they may reflect changes to cardiac electrophysiology, according to Dr. Bartlett. Those with abnormal readings were older on average (11.6 vs. 8.3 years; P < .005) and had a longer epilepsy duration (73 vs. 46 months; P = .004).

Dr. Gombolay has no relevant financial disclosures.

NICU signs hint at cerebral palsy risk

Article Type
Changed
Thu, 10/20/2022 - 14:58

 

– Cerebral palsy affects about 3 in every 1,000 children, but there is usually little sign of the condition at birth. Instead, it usually shows clinical manifestation between ages 2 and 5, and a diagnosis can trigger early interventions that can improve long-term outcomes.

Physicians and patients would benefit from a screening method for cerebral palsy at birth, but that has so far eluded researchers.

At the 2022 annual meeting of the Child Neurology Society, researchers presented evidence that respiratory rate measured in the last 24 hours of residence in the neonate intensive care unit (NICU) predicts later onset of cerebral palsy, with higher variability associated with increased cerebral palsy risk.

The study results were promising, according to Marc Patterson, MD, who comoderated the session. “It gives us more confidence in predicting the children at risk and making sure that they’re going to be followed closely to get the interventions they need to help them,” said Dr. Patterson, who is a professor of neurology, pediatrics, and medical genetics at Mayo Medical School in Rochester, Minn.

“By the time a child is 5 or 6, the symptoms are usually very obvious, but you really want to intervene as soon as possible before their brain’s plasticity decreases over time, so the earlier you can intervene in general, the better your results are going to be,” said Dr. Patterson.

There are tools available to diagnose cerebral palsy at an earlier age, including the Prechtl General Movements Assessment (GMA), which can be done up to 5 months of corrected age. It has 97% sensitivity and 89% specificity for cerebral palsy. The Hammersmith Infant Neurological Examination (HINE), which can be used in the same age range, and has 72-91% sensitivity and 100% specificity.

Both of the available tools are resource intensive and require trained clinicians, and may be unavailable in many areas. Despite these tools, early diagnosis of cerebral palsy is still underemployed, according to Arohi Saxena, a third-year medical student at Washington University in St. Louis, who presented the study results.
 

Respiratory rate variability may indicate increased risk

The researchers set out to identify objective metrics that correlated with HINE and GMA scores. They looked at kinematic data from practical assessments carried out by their physical therapists, as well as vital sign instability obtained at NICU discharge, which was based on suggestions that hemodynamic instability may be linked to later risk of cerebral palsy, according to Ms. Saxena.

They analyzed data from 31 infants with a corrected age of 8-25 weeks at a tertiary NICU follow-up clinic. Of these, 18 displayed fidgety movements on their Prechtl assessment, and 13 did not.

They used DeepLabCut software to analyze data from videos of the Prechtl assessment, with a focus on range and variance of hand and foot movements normalized to nose-to-umbilicus distance. They also analyzed pulse and respiratory data from the final 24 hours before NICU discharge.

They found that infants without fidgety movements had decreased hand and foot movement ranges (P = .04). There was no significant difference between the two groups with respect to pulse measurements. However, the respiratory rate range and variance was significantly higher in infants without fidgety movements. “Infants who are at higher risk for developing cerebral palsy had more respiratory instability early on in life,” said Ms. Saxena during her talk.

When they compared values to HINE scores, they found a correlation with less foot movement and a predisposition to develop cerebral palsy, but no correlation with hand movement. A lower HINE sore also correlated to larger respiratory rate range and variance (P < .01 for both).

“Our hypothesis to explain this link is that respiratory rate variability is likely driven by neonatal injury in the brainstem, where the respiratory centers are located. In some infants, this may correlate with more extensive cerebral injury that could predict the development of cerebral palsy,” said Ms. Saxena.

The group plans to increase its sample size as well as to conduct long-term follow-up on the infants to see how many receive formal diagnoses of cerebral palsy.

After her talk, asked by a moderator why motor assessments were not a reliable predictor in their study, Ms. Saxena pointed to the inexperience of assessors at the institution, where Prechtl testing had only recently begun.

“I think a lot of it is to do with the more subjective nature of the motor assessment. We definitely saw kind of a trend where in the earlier data that was collected, right when our institutions started doing these Prechtls, it was even less of a reliable effect. So I think possibly as clinicians continue to get more familiar with this assessment and there’s more like a validated and robust scoring system, maybe we’ll see a stronger correlation,” she said.

Ms. Saxena had no relevant disclosures. Coauthor Boomah Aravamuthan, MD, DPhil, is a consultant for Neurocrine Biosciences and has received royalties from UpToDate and funding from the National Institute of Neurological Disorders and Stroke.

At the 2022 annual meeting of the Child Neurology Society, researchers presented evidence that respiratory rate measured in the last 24 hours of residence in the neonate intensive care unit (NICU) predicts later onset of cerebral palsy, with higher variability associated with increased cerebral palsy risk.

The study results were promising, according to Marc Patterson, MD, who comoderated the session. “It gives us more confidence in predicting the children at risk and making sure that they’re going to be followed closely to get the interventions they need to help them,” said Dr. Patterson, who is a professor of neurology, pediatrics, and medical genetics at Mayo Medical School in Rochester, Minn.

“By the time a child is 5 or 6, the symptoms are usually very obvious, but you really want to intervene as soon as possible before their brain’s plasticity decreases over time, so the earlier you can intervene in general, the better your results are going to be,” said Dr. Patterson.

There are tools available to diagnose cerebral palsy at an earlier age, including the Prechtl General Movements Assessment (GMA), which can be done up to 5 months of corrected age. It has 97% sensitivity and 89% specificity for cerebral palsy. The Hammersmith Infant Neurological Examination (HINE), which can be used in the same age range, and has 72-91% sensitivity and 100% specificity.

Both of the available tools are resource intensive and require trained clinicians, and may be unavailable in many areas. Despite these tools, early diagnosis of cerebral palsy is still underemployed, according to Arohi Saxena, a third-year medical student at Washington University in St. Louis, who presented the study results.
 

Respiratory rate variability may indicate increased risk

The researchers set out to identify objective metrics that correlated with HINE and GMA scores. They looked at kinematic data from practical assessments carried out by their physical therapists, as well as vital sign instability obtained at NICU discharge, which was based on suggestions that hemodynamic instability may be linked to later risk of cerebral palsy, according to Ms. Saxena.

They analyzed data from 31 infants with a corrected age of 8-25 weeks at a tertiary NICU follow-up clinic. Of these, 18 displayed fidgety movements on their Prechtl assessment, and 13 did not.

They used DeepLabCut software to analyze data from videos of the Prechtl assessment, with a focus on range and variance of hand and foot movements normalized to nose-to-umbilicus distance. They also analyzed pulse and respiratory data from the final 24 hours before NICU discharge.

They found that infants without fidgety movements had decreased hand and foot movement ranges (P = .04). There was no significant difference between the two groups with respect to pulse measurements. However, the respiratory rate range and variance was significantly higher in infants without fidgety movements. “Infants who are at higher risk for developing cerebral palsy had more respiratory instability early on in life,” said Ms. Saxena during her talk.

When they compared values to HINE scores, they found a correlation with less foot movement and a predisposition to develop cerebral palsy, but no correlation with hand movement. A lower HINE sore also correlated to larger respiratory rate range and variance (P < .01 for both).

“Our hypothesis to explain this link is that respiratory rate variability is likely driven by neonatal injury in the brainstem, where the respiratory centers are located. In some infants, this may correlate with more extensive cerebral injury that could predict the development of cerebral palsy,” said Ms. Saxena.

The group plans to increase its sample size as well as to conduct long-term follow-up on the infants to see how many receive formal diagnoses of cerebral palsy.

After her talk, asked by a moderator why motor assessments were not a reliable predictor in their study, Ms. Saxena pointed to the inexperience of assessors at the institution, where Prechtl testing had only recently begun.

“I think a lot of it is to do with the more subjective nature of the motor assessment. We definitely saw kind of a trend where in the earlier data that was collected, right when our institutions started doing these Prechtls, it was even less of a reliable effect. So I think possibly as clinicians continue to get more familiar with this assessment and there’s more like a validated and robust scoring system, maybe we’ll see a stronger correlation,” she said.

Ms. Saxena had no relevant disclosures. Coauthor Boomah Aravamuthan, MD, DPhil, is a consultant for Neurocrine Biosciences and has received royalties from UpToDate and funding from the National Institute of Neurological Disorders and Stroke.

Research fails to justify post-COVID-19 wave of new-onset parkinsonism

Thu, 10/20/2022 - 14:02

 

There does not appear to be a definitive clinical link between new-onset parkinsonism and SARS-CoV-2 (COVID-19) infection, a multinational team of researchers reported at the International Congress of Parkinson’s Disease and Movement Disorders.

SARS-CoV-2 led to numerous discussions about a potential post–COVID-19 emergence of new-onset parkinsonism in susceptible individuals, often referred to in the literature as a “perfect storm” or a “wave” of parkinsonism, according to lead study author Iro Boura, MD.
 

Postviral precedence

“Although pathogens have been associated both with parkinsonism cases and Parkinson’s disease pathogenesis, the main concern of a potential connection between COVID-19 and new-onset parkinsonism arose from the historically documented parkinsonism cases appearing with encephalitis lethargica,” said Dr. Boura, a PhD candidate with the University of Crete in Greece and ex-fellow at King’s College London.

Dr. Iro Boura

Encephalitis lethargica appeared between 1916 and 1930 and has been epidemiologically related to the Spanish influenza pandemic, “although this link has been strongly debated by other researchers,” she added.

Because the connection of COVID-19 and parkinsonism seemed highly speculative, Dr. Boura and movement disorder specialist Kallol Ray Chaudhuri DSc, FRCP, MD, decided to search for any data supporting this notion. “Such a possibility would have a significant impact on everyday practice, including long follow-up neurological assessments of COVID-19 patients, along with greater vigilance in recognizing potential symptoms,” said Dr. Boura.  

They found no organized research exploring this link, aside from published case reports.
 

Scant evidence of a parkinsonism wave

The investigators conducted a review of the literature up to February 2022 to identify and analyze published cases of new-onset parkinsonism following a confirmed SARS-CoV-2 infection in otherwise healthy individuals. They ended up with 20 such cases.

Although some cases presented during or shortly after a COVID-19 infection, “the numbers are currently quite low to draw safe conclusions and generalize these findings as a risk of parkinsonism for the general population,” said Dr. Boura. Overall, parkinsonism appeared in the context of encephalopathy in 11 patients. Four patients developed postinfectious parkinsonism without encephalopathy. Another four had phenotypic similarities to idiopathic Parkinson’s disease. 

Nine patients were responsive to levodopa, while four required immunomodulatory treatment.

Although cases have already been reported, current data do not yet justify the concept of a post–COVID-19 parkinsonism wave. However, long-term surveillance is crucial to ensure that reports of further cases are carefully documented and analyzed.

Dr. Chaudhuri’s research team recently wrote a book exploring the numerous aspects of COVID-19 and parkinsonism, including Parkinson’s disease, said Dr. Boura.

“Moreover, the COVID-19 Clinical Neuroscience Study (COVID-CNS), with serial follow-up visits for COVID-19 patients, including imaging, is currently running in the United Kingdom with the active participation of Prof Chaudhuri’s team, aiming at revealing any potential parkinsonism cases after a COVID-19 infection,” she said.

This brain surgery was BYOS: Bring your own saxophone

Tumor vs. saxophone: The surgical grudge match

Brain surgery is a notoriously difficult task. There’s a reason we say, “Well, at least it’s not brain surgery” when we’re trying to convince someone that a task isn’t that tough. Make one wrong incision, cut the wrong neuron, and it’s goodbye higher cognitive function. And most people appreciate thinking. Crazy, right?

One would imagine that the act of brain surgery would become even more difficult when the patient brings his saxophone and plays it randomly throughout the operation. It’s a hospital, after all, not a jazz club. Patients don’t get to play musical instruments during other surgeries. Why should brain surgery patients get special treatment?

Paideia International Hospital

As it turns out, the musical performance was actually quite helpful. A man in Italy had a brain tumor in a particularly complex area, and he’s left-handed, which apparently makes the brain’s neural pathways much more complicated. Plus, he insisted that he retain his musical ability after the surgery. So he and his medical team had a crazy thought: Why not play the saxophone throughout the surgery? After all, according to head surgeon Christian Brogna, MD, playing an instrument means you understand music, which tests many higher cognitive functions such as coordination, mathematics, and memory.

And so, at various points throughout the 9-hour surgery, the patient played his saxophone for his doctors. Doing so allowed the surgeons to map the patient’s brain in a more complete and personalized fashion. With that extra knowledge, they were able to successfully remove the tumor while maintaining the patient’s musical ability, and the patient was discharged on Oct. 13, just 3 days after his operation.

While we’re happy the patient recovered, we do have to question his choice of music. During the surgery, he played the theme to the 1970 movie “Love Story” and the Italian national anthem. Perfectly fine pieces, no doubt, but the saxophone solo in “Jungleland” exists. And we could listen to that for 9 hours straight. In fact, we do that every Friday in the LOTME office.
 

Basketball has the Big Dance. Mosquitoes get the Big Sniff

In this week’s installment of our seemingly never-ending series, “Mosquitoes and the scientists who love them,” we visit The Rockefeller University in New York, where the olfactory capabilities of Aedes Aegypti – the primary vector species for Zika, dengue, yellow fever, and chikungunya – became the subject of a round robin–style tournament.

First things first, though. If you’re going to test mosquito noses, you have to give them something to smell. The researchers enrolled eight humans who were willing to wear nylon stockings on their forearms for 6 hours a day for multiple days. “Over the next few years, the researchers tested the nylons against each other in all possible pairings,” Leslie B. Vosshall, PhD, and associates said in a statement from the university. In other words, mosquito March Madness.

Nylons from different participants were hooked up in pairs to an olfactometer assay consisting of a plexiglass chamber divided into two tubes, each ending in a box that held a stocking. The mosquitoes were placed in the main chamber and observed as they flew down the tubes toward one stocking or the other.

Eventually, the “winner” of the “tournament” was Subject 33. And no, we don’t know why there was a Subject 33 since the study involved only eight participants. We do know that the nylons worn by Subject 33 were “four times more attractive to the mosquitoes than the next most-attractive study participant, and an astonishing 100 times more appealing than the least attractive, Subject 19,” according to the written statement.

Chemical analysis identified 50 molecular compounds that were elevated in the sebum of the high-attracting participants, and eventually the investigators discovered that mosquito magnets produced carboxylic acids at much higher levels than the less-attractive volunteers.

We could go on about the research team genetically engineering mosquitoes without odor receptors, but we have to save something for later. Tune in again next week for another exciting episode of “Mosquitoes and the scientists who love them.”
 

 

 

Are women better with words?

Men vs. Women is probably the oldest argument in the book, but there may now be movement. Researchers have been able not only to shift the advantage toward women, but also to use that knowledge to medical advantage.

When it comes to the matter of words and remembering them, women apparently have men beat. The margin is small, said lead author Marco Hirnstein, PhD, of the University of Bergen, Norway, but, after performing a meta-analysis of 168 published studies and PhD theses involving more than 350,000 participants, it’s pretty clear. The research supports women’s advantage over men in recall, verbal fluency (categorical and phonemic), and recognition.

So how is this information useful from a medical standpoint?

Dr. Hirnstein and colleagues suggested that this information can help in interpreting diagnostic assessment results. The example given was dementia diagnosis. Since women are underdiagnosed because their baseline exceeds average while men are overdiagnosed, taking gender and performance into account could clear up or catch cases that might otherwise slip through the cracks.

Now, let’s just put this part of the debate to rest and take this not only as a win for women but for science as well.

We could go on about the research team genetically engineering mosquitoes without odor receptors, but we have to save something for later. Tune in again next week for another exciting episode of “Mosquitoes and the scientists who love them.”
 

 

 

Are women better with words?

Men vs. Women is probably the oldest argument in the book, but there may now be movement. Researchers have been able not only to shift the advantage toward women, but also to use that knowledge to medical advantage.

When it comes to the matter of words and remembering them, women apparently have men beat. The margin is small, said lead author Marco Hirnstein, PhD, of the University of Bergen, Norway, but, after performing a meta-analysis of 168 published studies and PhD theses involving more than 350,000 participants, it’s pretty clear. The research supports women’s advantage over men in recall, verbal fluency (categorical and phonemic), and recognition.

So how is this information useful from a medical standpoint?

Dr. Hirnstein and colleagues suggested that this information can help in interpreting diagnostic assessment results. The example given was dementia diagnosis. Since women are underdiagnosed because their baseline exceeds average while men are overdiagnosed, taking gender and performance into account could clear up or catch cases that might otherwise slip through the cracks.

Now, let’s just put this part of the debate to rest and take this not only as a win for women but for science as well.
