Epilepsy & Seizures

Epilepsy was linked to a significantly increased the risk for hospitalization and death from COVID-19 early in the pandemic, while healthcare utilization rates in this patient population declined, data from two linked studies showed. 

Results showed that individuals with epilepsy had a 60% higher risk for hospitalization and a 33% higher risk of dying from COVID-19 than those without the disorder. However, during the pandemic, the number of hospitalizations and ER visits by people with epilepsy dropped by as much as 30%. 

“The neurotropic effects of Sars-CoV-2 might explain some of this increased risk for people with epilepsy, or epilepsy might be associated with alterations in the immune system, predisposing to more severe COVID-19,” wrote the investigators, led by Owen Pickrell, MBBChirm, PhD, Swansea University, United Kingdom.

The findings were published online March 5 in Epilepsia. 
 

Skill Shifting 

Epilepsy is one of the most common neurological conditions and affects approximately 50 million people worldwide, with significant comorbidity and an increased risk for early death.

During the pandemic, clinicians treating people with epilepsy and other conditions shifted their skills to treat an ever-increasing number of patients with COVID-19, which may have hindered epilepsy-specific services for a time.

To further explore how the COVID-19 pandemic may have affected the health of this patient population, researchers analyzed health records from a large database with information about hospital admissions, primary care visits, COVID-19 vaccination status, and demographics of 90% of Welsh residents.

Those living with epilepsy before or during the study period (March 1, 2020, to June 31, 2021) were identified and compared with controls without epilepsy. 

The analysis included approximately 27,280 people with epilepsy and 136,400 matched controls. Among those with epilepsy, there were 158 deaths (0.58%) and 933 hospitalizations (3.4%). In comparison, there were 370 deaths (0.27%) and 1871 hospitalizations (1.4%) in the control group.

Unadjusted analyses showed the risk of dying from COVID-19 for those with epilepsy vs controls was more than twofold higher (hazard ratio [HR], 2.15; 95% CI; 1.78-2.59) and the increase in the risk for hospitalization was similar (HR, 2.15; 95% CI; 1.94-2.37). 

After adjusting for 40 comorbidities, including serious mental illness, asthma, and diabetes, those with epilepsy had a 60% increased risk for hospitalization (adjusted HR [aHR], 1.60) and a 33% increased risk for death (aHR, 1.33) than those without epilepsy (all P < .0001). 

The findings “may have implications for prioritizing future COVID-19 treatments and vaccinations for people with epilepsy,” the investigators wrote.

Study limitations included the inability to account for the effect of vaccinations or prior infections with SARS-CoV-2. Moreover, the study did not account for geographical or temporal variations in prevalence and COVID-19 variants. 
 

Consultations Canceled 

In the related study, researchers analyzed healthcare utilization by people with epilepsy before and after the pandemic using the same database. Results showed hospital admissions, ER visits, and outpatient visits significantly decreased during the pandemic. 

In the year before the pandemic, people with epilepsy had double the rate of ER visits (rate ratio [RR], 2.36), hospital admissions (RR, 2.08), and outpatient appointments (RR, 1.92) compared with matched controls. 

However, during the pandemic there was a greater reduction in hospital admissions (RR, 0.70; 95% CI, 0.69-0.72) and ER visits (RR, 0.78; 95% CI, 0.77-0.70) in those with epilepsy versus matched controls (RR, 0.82; 95% CI, 0.81-0.83) as well as hospital visits and ER visits (RR, 0.87; 95% CI, 0.86-0.88; all P < .0001). New epilepsy diagnoses also decreased during the pandemic (RR, 0.73; P < .0001)

The redeployment of epileptologists during the pandemic also meant that epilepsy consultations and investigations were canceled, making it harder for people with epilepsy to access specialty care, the researchers noted. 

“Our research also showed that there were fewer new diagnoses of epilepsy and fewer contacts with health services by people with epilepsy, during the period we examined,” Huw Strafford, lead data analyst for the studies, said in a release.

Both studies were funded by Health and Care Research Wales. Dr. Pickrell reported receiving speaker fees from UCB Pharma and Angelini Pharma, travel grants from Angelini Pharma, and an unrestricted grant from UCB Pharma.

Stroke, Alzheimer’s disease, and other neurological conditions are now the leading cause of health loss and disability around the world, affecting nearly half of the world’s population, a new comprehensive analysis showed.

In 2021, neurological conditions were responsible for 443 million years of healthy life lost due to illness, disability, and premature death — a measurement known as disability-adjusted life years (DALY) — making them the top contributor to the global disease burden, ahead of cardiovascular diseases.

Some 3.4 billion people — 43% of the entire global population — had a neurological illness in 2021, the report noted.

“As the world’s leading cause of overall disease burden, and with case numbers rising 59% globally since 1990, nervous system conditions must be addressed through effective, culturally acceptable, and affordable prevention, treatment, rehabilitation, and long-term care strategies,” lead author Jaimie Steinmetz, PhD, from the Institute of Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release. 

The findings, from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021, “have important health service and policy implications and serve as evidence that global neurological heath loss has been under-recognized and is increasing and unevenly distributed geographically and socioeconomically,” the authors noted.

The study was published online in The Lancet: Neurology.
 

The Top 10

The top 10 contributors to neurological health loss in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer’s disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications from preterm birth, autistic spectrum disorders, and nervous system cancers.

Neurological consequences of COVID-19 ranked 20th out of 37 unique conditions assessed.

In 2021, there were more than 23 million global cases of COVID-19 with long-term cognitive symptoms or Guillain-Barré syndrome, accounting for 57% of all infectious neurological disease cases and contributing to 2.48 million years of healthy life lost, the study found.

The most prevalent neurological disorders were tension-type headache (about 2 billion cases) and migraine (about 1.1 billion cases), while diabetic neuropathy is the fastest-growing of all neurological conditions.

“The number of people with diabetic neuropathy has more than tripled globally since 1990, rising to 206 million in 2021. This is in line with the increase in the global prevalence of diabetes,” co-senior author Liane Ong, PhD, from IHME, said in the release.

The data showed striking differences in the burden of neurological conditions between world regions and national income levels, with over 80% of neurological deaths and health loss occurring in low- and middle-income countries.

Regions with the highest burden of neurological conditions were central and western sub-Saharan Africa, while high-income Asia Pacific and Australasia had the lowest burden.

“Nervous system health loss disproportionately impacts many of the poorest countries partly due to the higher prevalence of conditions affecting neonates and children under 5, especially birth-related complications and infections,” co-senior author Tarun Dua, MD, with the World Health Organization (WHO) brain health unit, noted in the news release.

“Improved infant survival has led to an increase in long-term disability, while limited access to treatment and rehabilitation services is contributing to the much higher proportion of deaths in these countries,” Dr. Dua said.
 

Prioritize Prevention

The analysis also provides estimates of the proportion of neurological conditions that are potentially preventable by eliminating known risk factors for stroke, dementia, multiple sclerosis, Parkinson’s disease, encephalitis, meningitis, and intellectual disability.

It shows that modifying 18 risk factors over a person’s lifetime — most importantly high systolic blood pressure — could prevent 84% of global DALYs from stroke. Controlling lead exposure could lower intellectual disability cases by 63% and reducing high fasting plasma glucose to normal levels could cut dementia by roughly 15%.

“Because many neurological conditions lack cures, and access to medical care is often limited, understanding modifiable risk factors and the potentially avoidable neurological condition burden is essential to help curb this global health crisis,” co-lead author Katrin Seeher, PhD, mental health specialist with WHO’s brain health unit, said in the release.

It’s important to note that nervous system conditions include infectious and vector-borne diseases and injuries as well as noncommunicable diseases and injuries, Dr. Steinmetz said, “demanding different strategies for prevention and treatment throughout life.”

“We hope that our findings can help policymakers more comprehensively understand the impact of neurological conditions on both adults and children to inform more targeted interventions in individual countries, as well as guide ongoing awareness and advocacy efforts around the world,” Dr. Steinmetz added.

In an accompanying editorial, Wolfgang Grisold, MD, president of the World Federation of Neurology, London, noted that the study builds on previous findings and expands the number of neurological conditions studied from 15 to 37.

“This important new GBD report highlights that the burden of neurological conditions is greater than previously thought,” wrote Dr. Grisold, who was not a part of the study. “In the next iteration, more attention should be given to neuromuscular diseases, the effects of cancer in the nervous system, and neuropathic pain. Comparing the disability caused by conditions with episodic occurrence versus those that cause permanent and progressive disease will remain challenging because the effects on the individuals vary substantially.”

Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.

Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.

“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam, Rotterdam, the Netherlands, said in a press release.

The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Ms. Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.

“The tasks that these dogs perform, along with their companionship, may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.

The findings were published online in Neurology.
 

Improve Quality of Life

The study included 25 individuals with medically refractory epilepsy who had an average of two or more seizures per week, with seizure characteristics associated with a high risk for injuries or dysfunction. They also had to be able to care for a service dog.

All were observed under usual care, which included antiseizure medications, neurostimulation devices, and other supportive therapies. Participants could then choose to work with a service dog that had completed socialization and obedience training or be assigned a puppy they would train at home.

The median follow-up was 19 months with usual care and 12 months with the intervention. Participants recorded seizure activity in diaries and completed surveys on seizure severity, quality of life, and well-being every 3 months. Daily seizure counts were converted to obtain cumulative seizure frequencies over 28-day periods.

Of the 25 original participants, six discontinued trial participation before the end of follow-up, four of whom left the study due to difficulty with dog care and training.

Participants receiving usual care reported an average of 115 seizures per 28-day period, while those with trained service dogs recorded 73 seizures in the same period, or a 37% difference between groups.

Researchers found that participants had an average of 31% fewer seizures during the past 3 months when they had seizure dogs, with seven participants achieving a 50%-100% reduction in seizures.

The number of seizure-free days increased from an average of 11 days per 28-day period before receiving a service dog to 15 days after working with a dog.

Scores on the EQ-5D-5L, which measures perceived health problems, decreased on average by 2.5% per consecutive 28-day period with the intervention, reflecting an increase in generic health-related quality of life (0.975; 95% CI, 0.954-0.997).

“These findings show that seizure dogs can help people with epilepsy,” said Ms. van Hezik-Wester. “However, we also found that this partnership with seizure dogs might not be the right fit for everyone, as some people discontinued their participation in this program. More research is needed to better understand which people can benefit from working with seizure dogs.”
 

Enhanced Quality of Life

In an accompanying editorial, Amir Mbonde, MB, and Amy Crepeau, MD, of Mayo Clinic in Phoenix, Arizona, noted the findings add to a growing body of work on the effectiveness of service dogs in reducing seizure frequency.

“In addition to improved seizure control, the EPISODE study demonstrated the benefit of seizure dogs in enhancing the quality of life for patients, a crucial component of comprehensive epilepsy care,” they wrote.

In prior studies, seizure dogs have identified an odor that a person emits before a seizure in up to 97% of people, they noted, adding that this ability “offers immense clinical benefits to people with epilepsy, enhancing their independence, social engagement, employment opportunities, self-confidence, and thus quality of life.”

Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.

Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.

“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam, Rotterdam, the Netherlands, said in a press release.

The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Ms. Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.

“The tasks that these dogs perform, along with their companionship, may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.

The findings were published online in Neurology.
 

Improve Quality of Life

The study included 25 individuals with medically refractory epilepsy who had an average of two or more seizures per week, with seizure characteristics associated with a high risk for injuries or dysfunction. They also had to be able to care for a service dog.

All were observed under usual care, which included antiseizure medications, neurostimulation devices, and other supportive therapies. Participants could then choose to work with a service dog that had completed socialization and obedience training or be assigned a puppy they would train at home.

The median follow-up was 19 months with usual care and 12 months with the intervention. Participants recorded seizure activity in diaries and completed surveys on seizure severity, quality of life, and well-being every 3 months. Daily seizure counts were converted to obtain cumulative seizure frequencies over 28-day periods.

Of the 25 original participants, six discontinued trial participation before the end of follow-up, four of whom left the study due to difficulty with dog care and training.

Participants receiving usual care reported an average of 115 seizures per 28-day period, while those with trained service dogs recorded 73 seizures in the same period, or a 37% difference between groups.

Researchers found that participants had an average of 31% fewer seizures during the past 3 months when they had seizure dogs, with seven participants achieving a 50%-100% reduction in seizures.

The number of seizure-free days increased from an average of 11 days per 28-day period before receiving a service dog to 15 days after working with a dog.

Scores on the EQ-5D-5L, which measures perceived health problems, decreased on average by 2.5% per consecutive 28-day period with the intervention, reflecting an increase in generic health-related quality of life (0.975; 95% CI, 0.954-0.997).

“These findings show that seizure dogs can help people with epilepsy,” said Ms. van Hezik-Wester. “However, we also found that this partnership with seizure dogs might not be the right fit for everyone, as some people discontinued their participation in this program. More research is needed to better understand which people can benefit from working with seizure dogs.”
 

Enhanced Quality of Life

In an accompanying editorial, Amir Mbonde, MB, and Amy Crepeau, MD, of Mayo Clinic in Phoenix, Arizona, noted the findings add to a growing body of work on the effectiveness of service dogs in reducing seizure frequency.

“In addition to improved seizure control, the EPISODE study demonstrated the benefit of seizure dogs in enhancing the quality of life for patients, a crucial component of comprehensive epilepsy care,” they wrote.

In prior studies, seizure dogs have identified an odor that a person emits before a seizure in up to 97% of people, they noted, adding that this ability “offers immense clinical benefits to people with epilepsy, enhancing their independence, social engagement, employment opportunities, self-confidence, and thus quality of life.”

TOPLINE:

Patients with multiple sclerosis (MS) have almost double the risk for seizures, with the risk even greater with sphingosine-1-phosphate receptor (S1PR) modulators, results of a new meta-analysis of randomized controlled trials (RCTs) suggest. Those with a progressive disease phenotype are at particularly high seizure risk.

METHODOLOGY:

• The meta-analysis included 63 phase 3 RCTs with 53,535 patients.
• Most of the studies included in the meta-analysis investigated disease-modifying treatments compared with placebo or an active comparator such as interferon beta, teriflunomide, and dimethyl fumarate, in terms of relapse rate and/or disability progression.
• Researchers extracted relevant information from studies, including MS subtype (clinically isolated syndrome, relapsing-remitting, primary progressive, or secondary progressive MS), mean Expanded Disability Status Scale (EDSS) score, lesion volume on T2-hyperintense sequence, normalized brain volume, and number of seizures or epilepsy events.
• They calculated the pooled effect size of studies on the incidence rate of seizure or epilepsy as the number of events per patient-years and explored which variables influenced the pooled effect size.

TAKEAWAY:

• A total of 120 patients experienced epileptic seizure events over a median follow-up of 2 years, resulting in a pooled incidence rate of 68.0 (95% CI, 49.1-86.9) per 100,000 patient-years, which investigators noted is significantly higher than the general population rate of 34.6.
• Higher seizure incidence rates were found among patients with progressive disease courses, longer time since clinical onset, higher EDSS scores, and lower normalized brain volume; age and T2 lesion volume did not affect the pooled effect size.
• Patients treated with S1PR modulators (fingolimod, ozanimod, ponesimod, and siponimod) had more than double the risk for seizure compared with placebo or comparators (estimated incident seizure risk ratio, 2.45; P = .008).

IN PRACTICE:

“Our findings underscore epilepsy as a significant comorbidity in MS and emphasize the necessity for further research into its triggers, preventive measures and treatment strategies,” the authors wrote.

SOURCE:

The study, led by Valeria Pozzilli, Unit of Neurology, Neurophysiology and Neurobiology, Department of Medicine and Surgery, Campus Bio-Medico University, Roma, Italy, was published online in the Journal of Neurology, Neurosurgery, and Psychiatry.

LIMITATIONS:

As none of the included RCTs considered epilepsy an exclusion criterion, patients with comorbid epilepsy may have been enrolled in these studies. There was significant diversity in reporting of adverse events across studies. While this study’s statistical methodology was robust, the findings can’t be applied directly to individuals due to the risk for ecological fallacy.

DISCLOSURES:

Pozzilli had no relevant conflicts of interests. See paper for disclosures of other authors.

The Centers for Disease Control and Prevention (CDC) estimates that 1.1% of US adults have epilepsy. Although 89% report seeing a physician in the past year about their condition, only 62% of adults saw a neurologist or seizure specialist. 

These findings prompted Rosemary Kobau, MPH, the acting team lead for the CDC’s epilepsy program, to take a closer look at referral patterns by primary care providers in the United States. Using data from a 2018 online survey of US internists, pediatricians, family medicine physicians, and nurse practitioners, she found that 90% of providers would refer a patient with new-onset seizure to a neurologist.

She also noticed what she calls a “big red flag”: “We found that 40% of primary care providers did not indicate that they would refer their patient with epilepsy to a neurologist when their patient fails to respond to treatment, or if they have a change in seizure activity,” Dr. Kobau told this news organization. Individuals with uncontrolled seizures are at risk for multiple adverse health outcomes, along with emotional problems, social stigma, and decreased life expectancy. 

Factors that influenced primary care clinicians to refer to a neurologist included prompt availability of appointments, ability to talk to the neurologist, and whether a patient’s insurance covered specialty visits. Proximity of a specialist also was cited as a barrier, because neurologists can be hard to find outside of urban centers.

Wait lists for neurologist are not like to get shorter any time soon, according to a 2019 report from the American Academy of Neurology (AAN). A 2013 workforce report from the AAN found 35 US states, representing 62% of the US population, had fewer neurologists than needed to meet demand. By 2025, demand is projected to exceed supply in 41 states. 

Much of the increasing demand for adult neurologists is driven by aging of the population, resulting in higher rates of stroke, Parkinson’s disease, and dementia. But pediatric neurologists are also overwhelmed: Pediatric neurology is one of the top three pediatric subspecialties with the longest wait times. The shortage is exacerbated by difficulties in transitioning adolescents with epilepsy — many diagnosed early in life with neurodevelopmental and epileptic encephalopathy and problem lists that include learning disorders, behavioral issues, and other chronic medical problems — to adult epilepsy specialists. 

Although one of the solutions offered by the AAN is more training in epilepsy management for non-neurologists (such as CME programs developed by the American Epilepsy Society), many primary care providers are overwhelmed already. Still, primary care providers are well-positioned to help answer some of the most important questions about the management of patients with seizure disorders. 
 

How to Help

“There’s a lot the pediatrician can do when a child presents with seizures,” said Sucheta Joshi, MD, who serves as the medical director of the Neurological Institute Comprehensive Epilepsy Center at Children’s Hospital Los Angeles.

Step one is helping to allay the fears of family members who witness a seizure. “They can talk about seizure safety, they can talk about first aid when a seizure happens, they can talk about what to do, what not to do,” she advised. Clinicians who see children can find resources for families on the American Academy of Pediatrics (AAP) National Coordinating Center for Epilepsy website, including a 24/7 helpline, information about local chapters of the Epilepsy Foundation, and first aid training for seizures. 

Fred Lado, MD, PhD, a professor of neurology at the Zucker School of Medicine at Hofstra-Norwell in Hempstead, New York, said that primary care clinicians have several decision points when it comes to their patients with epilepsy.

The first is whether to initiate medication after the first episode of seizure. Studies show that the risk for a second seizure decreases in patients started on anticonvulsant therapy after a first event, but many clinicians don›t want to commit patients to long-term therapy without more evidence that the patient has epilepsy. Studies have shown that delaying therapy until a second seizure occurs doesn›t negatively affect quality of life and long-term prognosis. 

The International League Against Epilepsy (ILAE) advised treatment for patients with two or more unprovoked seizures but revised its recommendation in 2014 to begin treatment after a first seizure for individuals at high risk for a second seizure. History of a brain insult related to a stroke, mass lesion in the brain, or trauma are risk factors for a second seizure, whereas seizures provoked by a concussion, alcohol withdrawal, or exposure to toxins carry low risk for additional episodes.

Dr. Lado also raised the importance of taking a good history from a patient presenting for medical care for a new-onset seizure to determine whether the recent episode is really the first such incident.

Up to half of patients presenting to emergency departments for convulsive seizures have a history of a preceding nonmotor seizure that the patient or their family members have failed to identify. As many as 60% of people with epilepsy have focal seizures, but the majority of these are nonmotor seizures. As a result, these patients often go without a diagnosis until they develop bilateral tonic-clonic seizures — by which time they may already been injured during a seizure or had an accident while driving.

In terms of imaging and other workup that should be performed prior to the first appointment with a pediatric neurologist or epilepsy specialist, Dr. Joshi generally recommends EEG. She also prefers MRI over CT, which is better for finding lesions that tend to cause seizures in kids such as developmental abnormalities like a cortical malformation or a perinatal process. Obtaining an MRI prior to seeing the neurologist is elective, depending on whether the history and clinical presentation suggest a focal lesion.

For adults, Dr. Lado also recommends an EEG and MRI to start but rarely advises other laboratory studies. When patients present to the emergency department with a new-onset seizure, the workup commonly includes a chemistry panel to rule out hypoglycemia or electrolyte abnormalities. But in the outpatient setting, where a patient describes symptoms of a seizure that occurred a week ago or longer, Dr. Lado said the yield of such assessments is low. 

“I think the labs are often more useful as you’re thinking about an anticonvulsant,” Dr. Lado said. Particularly for a patient who is facing a long wait to see specialist, obtaining baseline liver enzymes and a complete blood cell count is worthwhile, because many antiseizure medications can cause anemia or liver damage.

Dr. Lado agreed that referral to a specialist is critical for patients with drug-resistant seizures, defined by the ILAE as seizures that persist despite the use of two or more anticonvulsants. 

“One of the great problems in epilepsy care is a sort of sense of complacency,” he said. Some of his own patients have become comfortable with their epilepsy diagnosis and profess to be untroubled by having a few seizures per year. In 2018, Dr. Kobau was a co-author on a study reporting that less than half of US adults taking seizure medications were seizure-free in the past year. 

This scenario is an opportunity for primary care providers to help determine whether their patients are taking their antiseizure medication correctly. A referral to a specialist might not be necessary if the seizures are occurring because the patient’s prescription ran out. Similarly, if a patient doesn’t take the medication because of unpleasant side effects, raising the dose won’t help. 

Dr. Lado’s advice is to explore why the patient’s management plan is not working and make adjustments tailored to their needs. The solution might be as simple as changing the patient to an extended-release formulation to lower the number of daily doses needed, he said.

But for patients who do have recurrent seizures despite good adherence, Dr. Lado strongly urges a referral to an epilepsy specialist. He serves as president of the National Association of Epilepsy Centers (NAEC), a network of more than 260 epilepsy centers in the United States that offer the services of epileptologists, neurosurgeons, neuropsychologists, nurse specialists, EEG technologists, social workers, and others with training and experience in epilepsy care. In addition to adjusting and monitoring medications, patients seen at an NAEC can be evaluated for surgery, neurostimulators, and ketogenic diets.
 

Improving Self-Management

Another role that primary care can play is promoting self-efficacy among patients with epilepsy.

“Providers have historically tended to focus on medication adherence alone, ignoring other health enhancing behaviors, even just sleep hygiene,” Dr. Kobau said. But adequate sleep, regular exercise, a healthy diet, avoidance of tobacco and excessive alcohol, and stress management are all important for seizure management. 

In 2007, CDC launched the Managing Epilepsy Well (MEW) Network, which has the mission of advancing self-management research in collaboration with patients with epilepsy as well as a broad range of healthcare providers. “It’s a patient-driven kind of approach consistent with community-based, participatory practice research,” said Dr. Kobau, who oversees the initiative.

The MEW network, which consists of six prevention research centers funded by CDC, has piloted and evaluated several evidence-based programs that can help patients better control their epilepsy. 

One such intervention is Project Uplift, which delivers mindfulness-based cognitive-behavioral therapy in a virtual group setting. Behavioral therapy is important for people with seizure disorders, whose risk for depression is more than twice that of the general population. The initial trial found the intervention was effective in reducing depressive symptoms in participants, and research since has focused on adapting the program to provide culturally appropriate care to underserved populations. The eight sessions, held weekly, are available in both English and Spanish.

Another program, HOBSCOTCH, allows patients to meet one-on-one virtually with a trained coach to work on skills for improving attention and memory, common problems among people with epilepsy.

MINDSET involves a tablet-based clinical decision tool that patients can use to track their self-management behaviors, such as taking their medications, seizure triggers, symptoms of depression, and keeping their clinic appointments. It also helps them monitor whether they are getting adequate sleep, reducing their stress, and maintaining social networks. The tool generates a printable action plan for patients to prompt discussion and shared decision-making between patient and clinician to prioritize behavioral issues, set goals, and monitor changes over time.

Clinicians can refer patients to any of the MEW interventions, or patients can enroll themselves online.

 

Emerging Approaches

The AAN’s 2019 report promoted use of technological solutions to bridge the gap between primary care providers and scarce — as well as distant — neurologists. Many health systems support e-consults between clinicians, allowing simple discussions about medications and advice about testing recommended prior to a neurology visit. Initially developed for treatment for infection with hepatitis C virus, Project Extension for Community Healthcare Outcomes (ECHO) uses a central hub of specialists to support primary care providers via teleconference to conduct case reviews and didactic sessions. 

Much of Dr. Joshi’s work has focused on ways to coordinate care to children who live far from a pediatric epilepsy center. In a previous position at the University of Michigan, her team was one of four sites funded by the AAP’s National Coordinating Center for Epilepsy to pilot an intervention using telehealth. Implemented in 2017-2019, the initiative used quality improvement methodology to explore a model where patients went to the office of their primary care provider so that both could participate in the call with a neurologist.

The strategy was successful, resulting in reduced out-of-pocket costs, missed school hours, and missed work hours. Patient satisfaction was high (97%), and more parents in the intervention group than the control group agreed that it was easier to obtain appointments with specialists (95% vs 65%, respectively).

And since the pandemic, in-home telehealth visits have become commonplace, adding to the potential convenience and cost savings of telemedicine. 

CDC has invested in Project ECHO as a training program for nonspecialist providers to manage epilepsy. Based at the University of Cincinnati, the initial pilot from 2017 to 2019 trained primary care providers in Ohio and neighboring states using monthly 1-hour sessions via Zoom. According to Dr. Kobau, “Of those 164 primary care providers, 97% reported higher interest in improving their care of patients with epilepsy, and at least 98% reported that they were more confident in treating their patients with epilepsy.” Since that time, over 900 providers have received the training, which now attracts participants from all over the country.

Although the current burden of managing epilepsy now seems to be falling heavily on primary care providers, Dr. Lado said he believes they can provide useful insight into their patients’ history and needs: “I think they are in a unique and impactful position, mostly to refer those patients who are still having seizures.”

As a result, these patients often go without a diagnosis until they develop bilateral tonic-clonic seizures — by which time they may already been injured during a seizure or had an accident while driving.

In terms of imaging and other workup that should be performed prior to the first appointment with a pediatric neurologist or epilepsy specialist, Dr. Joshi generally recommends EEG. She also prefers MRI over CT, which is better for finding lesions that tend to cause seizures in kids such as developmental abnormalities like a cortical malformation or a perinatal process. Obtaining an MRI prior to seeing the neurologist is elective, depending on whether the history and clinical presentation suggest a focal lesion.

For adults, Dr. Lado also recommends an EEG and MRI to start but rarely advises other laboratory studies. When patients present to the emergency department with a new-onset seizure, the workup commonly includes a chemistry panel to rule out hypoglycemia or electrolyte abnormalities. But in the outpatient setting, where a patient describes symptoms of a seizure that occurred a week ago or longer, Dr. Lado said the yield of such assessments is low. 

“I think the labs are often more useful as you’re thinking about an anticonvulsant,” Dr. Lado said. Particularly for a patient who is facing a long wait to see specialist, obtaining baseline liver enzymes and a complete blood cell count is worthwhile, because many antiseizure medications can cause anemia or liver damage.

Dr. Lado agreed that referral to a specialist is critical for patients with drug-resistant seizures, defined by the ILAE as seizures that persist despite the use of two or more anticonvulsants. 

“One of the great problems in epilepsy care is a sort of sense of complacency,” he said. Some of his own patients have become comfortable with their epilepsy diagnosis and profess to be untroubled by having a few seizures per year. In 2018, Dr. Kobau was a co-author on a study reporting that less than half of US adults taking seizure medications were seizure-free in the past year. 

This scenario is an opportunity for primary care providers to help determine whether their patients are taking their antiseizure medication correctly. A referral to a specialist might not be necessary if the seizures are occurring because the patient’s prescription ran out. Similarly, if a patient doesn’t take the medication because of unpleasant side effects, raising the dose won’t help. 

Dr. Lado’s advice is to explore why the patient’s management plan is not working and make adjustments tailored to their needs. The solution might be as simple as changing the patient to an extended-release formulation to lower the number of daily doses needed, he said.

But for patients who do have recurrent seizures despite good adherence, Dr. Lado strongly urges a referral to an epilepsy specialist. He serves as president of the National Association of Epilepsy Centers (NAEC), a network of more than 260 epilepsy centers in the United States that offer the services of epileptologists, neurosurgeons, neuropsychologists, nurse specialists, EEG technologists, social workers, and others with training and experience in epilepsy care. In addition to adjusting and monitoring medications, patients seen at an NAEC can be evaluated for surgery, neurostimulators, and ketogenic diets.
 

Improving Self-Management

Another role that primary care can play is promoting self-efficacy among patients with epilepsy.

“Providers have historically tended to focus on medication adherence alone, ignoring other health enhancing behaviors, even just sleep hygiene,” Dr. Kobau said. But adequate sleep, regular exercise, a healthy diet, avoidance of tobacco and excessive alcohol, and stress management are all important for seizure management. 

In 2007, CDC launched the Managing Epilepsy Well (MEW) Network, which has the mission of advancing self-management research in collaboration with patients with epilepsy as well as a broad range of healthcare providers. “It’s a patient-driven kind of approach consistent with community-based, participatory practice research,” said Dr. Kobau, who oversees the initiative.

The MEW network, which consists of six prevention research centers funded by CDC, has piloted and evaluated several evidence-based programs that can help patients better control their epilepsy. 

One such intervention is Project Uplift, which delivers mindfulness-based cognitive-behavioral therapy in a virtual group setting. Behavioral therapy is important for people with seizure disorders, whose risk for depression is more than twice that of the general population. The initial trial found the intervention was effective in reducing depressive symptoms in participants, and research since has focused on adapting the program to provide culturally appropriate care to underserved populations. The eight sessions, held weekly, are available in both English and Spanish.

Another program, HOBSCOTCH, allows patients to meet one-on-one virtually with a trained coach to work on skills for improving attention and memory, common problems among people with epilepsy.

MINDSET involves a tablet-based clinical decision tool that patients can use to track their self-management behaviors, such as taking their medications, seizure triggers, symptoms of depression, and keeping their clinic appointments. It also helps them monitor whether they are getting adequate sleep, reducing their stress, and maintaining social networks. The tool generates a printable action plan for patients to prompt discussion and shared decision-making between patient and clinician to prioritize behavioral issues, set goals, and monitor changes over time.

Clinicians can refer patients to any of the MEW interventions, or patients can enroll themselves online.

 

Emerging Approaches

The AAN’s 2019 report promoted use of technological solutions to bridge the gap between primary care providers and scarce — as well as distant — neurologists. Many health systems support e-consults between clinicians, allowing simple discussions about medications and advice about testing recommended prior to a neurology visit. Initially developed for treatment for infection with hepatitis C virus, Project Extension for Community Healthcare Outcomes (ECHO) uses a central hub of specialists to support primary care providers via teleconference to conduct case reviews and didactic sessions. 

Much of Dr. Joshi’s work has focused on ways to coordinate care to children who live far from a pediatric epilepsy center. In a previous position at the University of Michigan, her team was one of four sites funded by the AAP’s National Coordinating Center for Epilepsy to pilot an intervention using telehealth. Implemented in 2017-2019, the initiative used quality improvement methodology to explore a model where patients went to the office of their primary care provider so that both could participate in the call with a neurologist.

The strategy was successful, resulting in reduced out-of-pocket costs, missed school hours, and missed work hours. Patient satisfaction was high (97%), and more parents in the intervention group than the control group agreed that it was easier to obtain appointments with specialists (95% vs 65%, respectively).

And since the pandemic, in-home telehealth visits have become commonplace, adding to the potential convenience and cost savings of telemedicine. 

CDC has invested in Project ECHO as a training program for nonspecialist providers to manage epilepsy. Based at the University of Cincinnati, the initial pilot from 2017 to 2019 trained primary care providers in Ohio and neighboring states using monthly 1-hour sessions via Zoom. According to Dr. Kobau, “Of those 164 primary care providers, 97% reported higher interest in improving their care of patients with epilepsy, and at least 98% reported that they were more confident in treating their patients with epilepsy.” Since that time, over 900 providers have received the training, which now attracts participants from all over the country.

Although the current burden of managing epilepsy now seems to be falling heavily on primary care providers, Dr. Lado said he believes they can provide useful insight into their patients’ history and needs: “I think they are in a unique and impactful position, mostly to refer those patients who are still having seizures.”

The Centers for Disease Control and Prevention (CDC) estimates that 1.1% of US adults have epilepsy. Although 89% report seeing a physician in the past year about their condition, only 62% of adults saw a neurologist or seizure specialist. 

These findings prompted Rosemary Kobau, MPH, the acting team lead for the CDC’s epilepsy program, to take a closer look at referral patterns by primary care providers in the United States. Using data from a 2018 online survey of US internists, pediatricians, family medicine physicians, and nurse practitioners, she found that 90% of providers would refer a patient with new-onset seizure to a neurologist.

She also noticed what she calls a “big red flag”: “We found that 40% of primary care providers did not indicate that they would refer their patient with epilepsy to a neurologist when their patient fails to respond to treatment, or if they have a change in seizure activity,” Dr. Kobau told this news organization. Individuals with uncontrolled seizures are at risk for multiple adverse health outcomes, along with emotional problems, social stigma, and decreased life expectancy. 

Factors that influenced primary care clinicians to refer to a neurologist included prompt availability of appointments, ability to talk to the neurologist, and whether a patient’s insurance covered specialty visits. Proximity of a specialist also was cited as a barrier, because neurologists can be hard to find outside of urban centers.

Wait lists for neurologist are not like to get shorter any time soon, according to a 2019 report from the American Academy of Neurology (AAN). A 2013 workforce report from the AAN found 35 US states, representing 62% of the US population, had fewer neurologists than needed to meet demand. By 2025, demand is projected to exceed supply in 41 states. 

Much of the increasing demand for adult neurologists is driven by aging of the population, resulting in higher rates of stroke, Parkinson’s disease, and dementia. But pediatric neurologists are also overwhelmed: Pediatric neurology is one of the top three pediatric subspecialties with the longest wait times. The shortage is exacerbated by difficulties in transitioning adolescents with epilepsy — many diagnosed early in life with neurodevelopmental and epileptic encephalopathy and problem lists that include learning disorders, behavioral issues, and other chronic medical problems — to adult epilepsy specialists. 

Although one of the solutions offered by the AAN is more training in epilepsy management for non-neurologists (such as CME programs developed by the American Epilepsy Society), many primary care providers are overwhelmed already. Still, primary care providers are well-positioned to help answer some of the most important questions about the management of patients with seizure disorders. 
 

How to Help

“There’s a lot the pediatrician can do when a child presents with seizures,” said Sucheta Joshi, MD, who serves as the medical director of the Neurological Institute Comprehensive Epilepsy Center at Children’s Hospital Los Angeles.

Step one is helping to allay the fears of family members who witness a seizure. “They can talk about seizure safety, they can talk about first aid when a seizure happens, they can talk about what to do, what not to do,” she advised. Clinicians who see children can find resources for families on the American Academy of Pediatrics (AAP) National Coordinating Center for Epilepsy website, including a 24/7 helpline, information about local chapters of the Epilepsy Foundation, and first aid training for seizures. 

Fred Lado, MD, PhD, a professor of neurology at the Zucker School of Medicine at Hofstra-Norwell in Hempstead, New York, said that primary care clinicians have several decision points when it comes to their patients with epilepsy.

The first is whether to initiate medication after the first episode of seizure. Studies show that the risk for a second seizure decreases in patients started on anticonvulsant therapy after a first event, but many clinicians don›t want to commit patients to long-term therapy without more evidence that the patient has epilepsy. Studies have shown that delaying therapy until a second seizure occurs doesn›t negatively affect quality of life and long-term prognosis. 

The International League Against Epilepsy (ILAE) advised treatment for patients with two or more unprovoked seizures but revised its recommendation in 2014 to begin treatment after a first seizure for individuals at high risk for a second seizure. History of a brain insult related to a stroke, mass lesion in the brain, or trauma are risk factors for a second seizure, whereas seizures provoked by a concussion, alcohol withdrawal, or exposure to toxins carry low risk for additional episodes.

Dr. Lado also raised the importance of taking a good history from a patient presenting for medical care for a new-onset seizure to determine whether the recent episode is really the first such incident.

Up to half of patients presenting to emergency departments for convulsive seizures have a history of a preceding nonmotor seizure that the patient or their family members have failed to identify. As many as 60% of people with epilepsy have focal seizures, but the majority of these are nonmotor seizures. As a result, these patients often go without a diagnosis until they develop bilateral tonic-clonic seizures — by which time they may already been injured during a seizure or had an accident while driving.

She also prefers MRI over CT, which is better for finding lesions that tend to cause seizures in kids such as developmental abnormalities like a cortical malformation or a perinatal process. Obtaining an MRI prior to seeing the neurologist is elective, depending on whether the history and clinical presentation suggest a focal lesion.

The first updated guidelines for specialized epilepsy centers in a decade reflect a shift toward addressing patients’ overall well-being, including recommendations for genetic testing and counseling, mental health screening, and greater attention to special-needs populations. 

The guidelines — the first from the National Association of Epilepsy Centers (NAEC) in a decade — describe the comprehensive services and resources specialized epilepsy centers should provide to improve quality of care for people living with epilepsy.

“In addition to advances in medicine, there has been a shift toward addressing overall well-being beyond seizure management,” Fred A. Lado, MD, PhD, NAEC president and guideline panel cochair, said in a news release. “This includes care for comorbid conditions like anxiety and depression, enhanced communication between the patient and care team, and addressing health disparities in the epilepsy community.

The guidance was developed by a panel of multidisciplinary experts, which is the first time that the NAEC has gone beyond the field of neurology to seek input from other medical specialists and allied health personnel, the panel noted. 

“Expanded guidelines are also sorely needed to help centers and hospitals obtain the resources to provide this level of comprehensive care,” said Dr. Lado, regional director of epilepsy and professor of neurology at Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York. 

An executive summary of the guidelines was published online in Neurology. 
 

A Multidisciplinary Approach

Epilepsy is one of the most common chronic neurologic conditions worldwide, affecting an estimated 3.4 million people in the United States alone. Recurring seizures can be debilitating and, in some cases, life-threatening. 

To update epilepsy care guidelines, an expert panel of 41 stakeholders with diverse expertise evaluated the latest evidence and reached consensus on 52 recommendations spanning a range of services that make up high-quality epilepsy care. 

“This is exhibited in a greater emphasis on multidisciplinary care conferences, screening for comorbidities of epilepsy, and providing access to other specialty services in addition to the core epilepsy center components of outpatient care, diagnostic procedures, and epilepsy surgery,” they wrote. 

For the first time, the guidelines advise specialized epilepsy centers to offer genetic testing and counseling, provide more education and communication for patients, give greater attention to special-needs populations, employ a care coordinator to organize and facilitate multidisciplinary care, provide mental health screening, and address health disparities and inequities.

“All recommendations quickly reached consensus despite there being such a diverse panel of stakeholders, which emphasizes that the recommendations reflect the important elements of healthcare services that should be in place for an epilepsy center to provide the highest quality of care,” said Susan Arnold, MD, guideline panel co-chair and a pediatric epileptologist at Yale University School of Medicine, New Haven, Connecticut.

“But epilepsy centers will need the resources to provide this comprehensive level of care. We hope the guidelines will help increase health insurer and institutional support and recognition of these recommendations,” Dr. Arnold added. 

The guidelines were funded by NAEC. Dr. Lado has no relevant disclosures. Dr. Arnold holds stock in Pfizer. A complete list of disclosures for the guideline panel is available with the original article.

When pediatric patients with epilepsy shift to adult care, inherent challenges are complicated by a near-total lack of efforts to smooth the transition, according to a recent survey. Many respondents received little to no information regarding the process, and many adults were still receiving care from family physicians or pediatric neurologists. The study was published online in Epilepsy & Behavior.

Room for Improvement

“We are not doing as good a job with planning for transition as we should,” said Elaine C. Wirrell, MD, who was not involved with the study. “It is not just a simple issue of sending your patient to an adult neurologist. Transition is a process that happens over time, so we need to do a better job getting our families ready for moving on to an adult provider.” Dr. Wirrell is director of pediatric epilepsy and professor of neurology at the Mayo Clinic in Rochester, Minnesota.

Clumsy Transitions

Investigators distributed a 25-question survey to patients and caregivers who attended the 2019 Epilepsy Awareness Day at Disneyland, and through online support groups in North America. Among 58 responses, 32 came from patients between ages 12 and 17 years or their caregivers.

Despite attempts to recruit a diverse cross-section of respondents, most patients had severe epilepsy and comorbidities: 43% had daily or weekly seizures; 45% were on three or more antiseizure medications; and 74% had intellectual disabilities.

Many children with early-life epilepsies suffer from developmental and epileptic encephalopathy, which has associated non-seizure symptoms including learning challenges, behavioral issues, and other medical concerns, Dr. Wirrell said. Therefore, she said, finding a neurologist who treats adults — and has the expertise and interest to care for such patients — can be difficult.

“We’re seeing many patients not making that transition, or maybe not making it appropriately, so they’re not necessarily getting to the providers who have the most expertise in managing their epilepsy.” Among adults surveyed, 27% were still being followed by pediatric neurologists, and 35% were visiting family doctors for epilepsy-related treatment.

Because the needs of children with complex epilepsy can extend well beyond neurology, Dr. Wirrell added, managing such cases often requires multidisciplinary pediatric teams. “Finding that team on the adult side is more challenging.” As a result, she said, patients may transfer their neurology care without getting additional support for comorbidities such as mood disorders and learning disabilities.

The foregoing challenges are complicated by the fact that pediatric neurologists often lack the time (and in the United States, reimbursement) to adequately address the transition process, said Dr. Wirrell. Providers in freestanding children’s hospitals may face additional challenges coordinating with adult-care providers outside their facilities, she said.

“There’s also potentially a reluctance of both families and physicians to transition the patient on, because there’s concern that maybe there isn’t anybody on the adult side who is able to do as good a job as what they have on the pediatric side.”
 

Well-Coordinated Transitions Should Have No Surprises

Transition should be a planned, independence-promoting process that results in smooth, well-coordinated movement of pediatric patients into adult care — one without surprises or disconnections, the authors wrote. However, 55% of respondents never heard the term “transition” from any provider, even though 69% of patients were being treated in academic specialty centers.

Among 12- to 17-year-olds, 72% had never discussed transition with their healthcare team. That figure includes no 17-year-olds. Approximately 90% of respondents said they received sufficient time during healthcare visits, but 54% reported feeling stressed when moving from pediatric to adult care.

Given resource constraints in many pediatric epilepsy programs, the study authors recommended patient-empowerment tools such as a transition toolkit to help patients and families navigate the transition process even in places without formal transition programs.

“Many of these children are coming over with boatloads of medical records,” Dr. Wirrell said. “It’s not fair to the adult provider, who then has to go through all those records.” Instead, she said, pediatric teams should provide succinct summaries of relevant test results, medication side effects, prior treatments tried, and the like. “Those summaries are critically important so that we can get information to the person who needs it.”

Although successful transition requires significant coordination, she added, much of the process can often be handled by nonphysicians. “There are some very good nurse-led transition programs. Often, we can have a nurse providing education to the family and even potentially having a joint visit with an adult epilepsy nurse for complex patients.”

Pediatric providers also must know when to begin the transition process, Dr. Wirrell said. As soon as patients are 13 or 14 years old, she suggested discussing the process with them and their families every 6 to 12 months, covering specifics ranging from how to order medications to why adult patients may need power of attorney designees.

On a broader scale, said Dr. Wirrell, a smooth handoff requires planning. Fortunately, she said, the topic is becoming a significant priority for a growing number of children’s hospitals specific not only to epilepsy, but also to other chronic illnesses.

When pediatric patients with epilepsy shift to adult care, inherent challenges are complicated by a near-total lack of efforts to smooth the transition, according to a recent survey. Many respondents received little to no information regarding the process, and many adults were still receiving care from family physicians or pediatric neurologists. The study was published online in Epilepsy & Behavior.

Room for Improvement

“We are not doing as good a job with planning for transition as we should,” said Elaine C. Wirrell, MD, who was not involved with the study. “It is not just a simple issue of sending your patient to an adult neurologist. Transition is a process that happens over time, so we need to do a better job getting our families ready for moving on to an adult provider.” Dr. Wirrell is director of pediatric epilepsy and professor of neurology at the Mayo Clinic in Rochester, Minnesota.

Clumsy Transitions

Investigators distributed a 25-question survey to patients and caregivers who attended the 2019 Epilepsy Awareness Day at Disneyland, and through online support groups in North America. Among 58 responses, 32 came from patients between ages 12 and 17 years or their caregivers.

Despite attempts to recruit a diverse cross-section of respondents, most patients had severe epilepsy and comorbidities: 43% had daily or weekly seizures; 45% were on three or more antiseizure medications; and 74% had intellectual disabilities.

Many children with early-life epilepsies suffer from developmental and epileptic encephalopathy, which has associated non-seizure symptoms including learning challenges, behavioral issues, and other medical concerns, Dr. Wirrell said. Therefore, she said, finding a neurologist who treats adults — and has the expertise and interest to care for such patients — can be difficult.

“We’re seeing many patients not making that transition, or maybe not making it appropriately, so they’re not necessarily getting to the providers who have the most expertise in managing their epilepsy.” Among adults surveyed, 27% were still being followed by pediatric neurologists, and 35% were visiting family doctors for epilepsy-related treatment.

Because the needs of children with complex epilepsy can extend well beyond neurology, Dr. Wirrell added, managing such cases often requires multidisciplinary pediatric teams. “Finding that team on the adult side is more challenging.” As a result, she said, patients may transfer their neurology care without getting additional support for comorbidities such as mood disorders and learning disabilities.

The foregoing challenges are complicated by the fact that pediatric neurologists often lack the time (and in the United States, reimbursement) to adequately address the transition process, said Dr. Wirrell. Providers in freestanding children’s hospitals may face additional challenges coordinating with adult-care providers outside their facilities, she said.

“There’s also potentially a reluctance of both families and physicians to transition the patient on, because there’s concern that maybe there isn’t anybody on the adult side who is able to do as good a job as what they have on the pediatric side.”
 

Well-Coordinated Transitions Should Have No Surprises

Transition should be a planned, independence-promoting process that results in smooth, well-coordinated movement of pediatric patients into adult care — one without surprises or disconnections, the authors wrote. However, 55% of respondents never heard the term “transition” from any provider, even though 69% of patients were being treated in academic specialty centers.

Among 12- to 17-year-olds, 72% had never discussed transition with their healthcare team. That figure includes no 17-year-olds. Approximately 90% of respondents said they received sufficient time during healthcare visits, but 54% reported feeling stressed when moving from pediatric to adult care.

Given resource constraints in many pediatric epilepsy programs, the study authors recommended patient-empowerment tools such as a transition toolkit to help patients and families navigate the transition process even in places without formal transition programs.

“Many of these children are coming over with boatloads of medical records,” Dr. Wirrell said. “It’s not fair to the adult provider, who then has to go through all those records.” Instead, she said, pediatric teams should provide succinct summaries of relevant test results, medication side effects, prior treatments tried, and the like. “Those summaries are critically important so that we can get information to the person who needs it.”

Although successful transition requires significant coordination, she added, much of the process can often be handled by nonphysicians. “There are some very good nurse-led transition programs. Often, we can have a nurse providing education to the family and even potentially having a joint visit with an adult epilepsy nurse for complex patients.”

Pediatric providers also must know when to begin the transition process, Dr. Wirrell said. As soon as patients are 13 or 14 years old, she suggested discussing the process with them and their families every 6 to 12 months, covering specifics ranging from how to order medications to why adult patients may need power of attorney designees.

ORLANDO — Experts shed light on the applications, benefits, and pitfalls of artificial intelligence (AI) during the Merrit-Putnam Symposium at the annual meeting of the American Epilepsy Society (AES).

In a session titled “Artificial Intelligence Fundamentals and Breakthrough Applications in Epilepsy,” University of Pittsburgh neurologist and assistant professor Wesley Kerr, MD, PhD, provided an overview of AI as well its applications in neurology. He began by addressing perhaps one of the most controversial topics regarding AI in the medical community: clinicians’ fear of being replaced by technology.

“Artificial intelligence will not replace clinicians, but clinicians assisted by artificial intelligence will replace clinicians without artificial intelligence,” he told the audience.
 

To Optimize AI, Clinicians Must Lay the Proper Foundation

Dr. Kerr’s presentation focused on providing audience members with tools to help them evaluate new technologies, recognize benefits, and identify key costs and limitations associated with AI implementation and integration into clinical practice.

Before delving deeper, one must first understand basic terminology regarding AI. Without this knowledge, clinicians may inadvertently introduce bias or errata or fail to understand how to best leverage the technology to enhance the quality of the practice while improving patient outcomes.

Machine learning (ML) describes the process of using data to learn a specific task. Deep learning (DL) stacks multiple layers of ML to improve performance on the task. Lastly, generative AI generates content such as text, images, and media.

Utilizing AI effectively in clinical applications involves tapping into select features most related to prediction (for example, disease factors) and grouping features into categories based on measuring commonalities such as factor composition in a population. This information should be used in training data only.

Fully understanding ML/AI allows clinicians to use it as a diagnostic test by exploiting a combination of accuracy, sensitivity, and specificity, along with positive and negative predictive values.
 

Data Fidelity and Integrity Hinge on Optimal Data Inputs

In the case of epilepsy, calibration curves can provide practical guidance in terms of predicting impending seizures.

“ML/AI needs gold-standard labels for evaluation,” Dr. Kerr said. He went on to stress the importance of quality data inputs to optimize the fidelity of AI’s predictive analytics.

“If you input garbage, you’ll get garbage out,” he said. “So a lot of garbage going in means a lot of garbage out.”

Such “garbage” can result in missed or erroneous diagnoses, or even faulty predictions. Even when the data are complete, AI can draw incorrect conclusions based on trends for which it lacks proper context.

Dr. Kerr used epilepsy trends in the Black population to illustrate this problem.

“One potential bias is that AI can figure out a patient is Black without being told, and based on data that Black patients are less likely to get epilepsy surgery,” he said, “AI would say they don’t need it because they’re Black, which isn’t true.”

In other words, ML/AI can use systematic determinants of health, such as race, to learn what Dr. Kerr referred to as an “inappropriate association.”

For that reason, ML/AI users must test for bias.

Such data are often retrieved from electronic health records (EHR), which serve as an important source of data ML/AI input. Using EHR makes sense, as they are a major source of missed potential in improving prompt treatment. According to Dr. Kerr, 20% of academic neurologists’ notes miss seizure frequency, and 30% miss the age of onset.

In addition, International Classification of Diseases (ICD) codes create another hurdle depending on the type of code used. For example, epilepsy with G40 or 2 codes of R56 is reliable, while focal to bilateral versus generalized epilepsy proves more challenging.
 

AI Improves Efficiency in National Language Generation

Large language models (LLM) look at first drafts and can save time on formatting, image selection, and construction. Perhaps ChatGPT is the most famous LLM, but other tools in this category include Open AI and Bard. LLMs are trained on “the whole internet” and use publicly accessible text.

In these cases, prompts serve as input data. Output data are predictions of the first and subsequent words.

Many users appreciate the foundation LLMs provide in terms of facilitating and collating research and summarizing ideas. The LLM-generated text actually serves as a first draft, saving users time on more clerical tasks such as formatting, image selection, and structure. Notwithstanding, these tools still require human supervision to screen for hallucinations or to add specialized content.

“LLMs are a great starting place to save time but are loaded with errors,” Dr. Kerr said.

Even if the tools could produce error-free content, ethics still come into play when using AI-generated content without any alterations. Any ML/AI that has not been modified or supervised is considered plagiarism.

Yet, interestingly enough, Dr. Kerr found that patients respond more positively to AI than physicians when interacting.

“Patients felt that AI was more sensitive and compassionate because it was longer-winded and humans are short,” he said. He went on to argue that AI might actually prove useful in helping physicians to improve the quality of their patient interactions.

Dr. Kerr left the audience with these key takeaways:

• ML/AI is just one type of clinical tool with benefits and limitations. The technology conveys the advantages of freeing up the clinician’s time to focus on more human-centered tasks, improving clinical decisions in challenging situations, and improving efficiency.
• However, healthcare systems should understand that ML/AI is not 100% foolproof, as the software’s knowledge is limited to its training exposure, and proper use requires supervision.

ORLANDO — The epilepsy community has yet to come to a consensus on genetic testing. During a session at the annual meeting of the American Epilepsy Society (AES), researchers and clinicians convened to share their insights on genetic testing of adult patients with epilepsy.

Colin Ellis, MD, assistant professor of neurology at the Hospital of the University of Pennsylvania in Philadelphia, shared his clinical experience to explain the importance of genetic testing in adults patients despite access challenges, limited information on certain variants, and physician reticence.

“There’s a false misconception that genetic testing should only apply to children,” Dr. Ellis told the audience. “The earlier the onset of seizures, the more likely you are to find a genetic cause.”
 

Guidelines Differ

The International League Against Epilepsy Task Force for Clinical Genetic Testing, Development and Epileptic Encephalopathies (DEE) recommends conducting genetic testing in patients who have focal or generalized epilepsies to whom the following circumstances apply: autism or dysmorphism, familial history, or drug-resistant epilepsy.

However, the National Society of Genetic Counselors’ guidelines recommends genetic testing for patients who have any unexplained or idiopathic epilepsies.

Guidelines identify the patients who should get tested regardless of their age.
 

Personal Experience

Dr. Ellis, who has spent nearly 5 years running tests on patients with epilepsy, recently tested the 300th patient at his clinic. According to him, the yield is higher in focal epilepsy than in general epilepsy — an occurrence that counters what many believe.

“Focal epilepsies are more common than monogenic epilepsies but not intuitive to many people in the industry, despite being stated in the literature,” he said. “The absence of family history shouldn’t preclude you from genetic testing because it’s still possible to have a de novo variant not inherited from either parent.”

Genetic testing can be conducted by interrogating either the exome or the genome. However, cost remains a major barrier to access.

Dr. Ellis made several arguments supporting the use of genetic testing. First, genetic testing allows for a higher diagnostic yield (i.e., 24% versus 19% in panels and 9% in microarrays). Genetic testing provides a more comprehensive overview of a patient’s genetic landscape, and it can enhance the ability to identify certain epileptic conditions, such as those caused by monogenic epilepsy — a condition associated with 926 different genes.

“You’re also less likely to find variants of uncertain significance (VUS),” Dr. Ellis said. “Regardless, you should provide the lab with phenotype information because it will help them help you.”
 

Variants of Uncertain Significance

The National Human Genome Research Institute defines VUS as a variant found in a patient’s genome for which it remains unclear as to whether a health condition is causing the variant. Oftentimes, such variants have very little information available due to their rarity.

In order to resolve VUS, Dr. Ellis recommended family segregation. “If the VUS appears to be de novo, you should test the parent because if they carry the gene, then it’s probably not the cause,” he said.

Dr. Ellis outlined several steps in resolving VUS.

For starters, clinicians should determine the phenotypic fit and run some ancillary tests. For example, in the case of Glu 1 abnormalities, one should consider conducting a spinal tap to determine whether the patient has cerebral spinal fluid before taking additional action.

In addition, Dr. Ellis recommends defining variant characteristics, as it becomes important in determining whether it is appropriate to take action because the majority of variances are benign.

“The take-home point is that you should not act clinically on a VUS unless you know what you’re doing,” he said. “I also disagree with the belief that VUS are rare — it’s just that they cause so much anxiety because we’re uncomfortable with this kind of testing.”

“Focal epilepsies are more common than monogenic epilepsies but not intuitive to many people in the industry, despite being stated in the literature,” he said. “The absence of family history shouldn’t preclude you from genetic testing because it’s still possible to have a de novo variant not inherited from either parent.”

Genetic testing can be conducted by interrogating either the exome or the genome. However, cost remains a major barrier to access.

Dr. Ellis made several arguments supporting the use of genetic testing. First, genetic testing allows for a higher diagnostic yield (i.e., 24% versus 19% in panels and 9% in microarrays). Genetic testing provides a more comprehensive overview of a patient’s genetic landscape, and it can enhance the ability to identify certain epileptic conditions, such as those caused by monogenic epilepsy — a condition associated with 926 different genes.

“You’re also less likely to find variants of uncertain significance (VUS),” Dr. Ellis said. “Regardless, you should provide the lab with phenotype information because it will help them help you.”
 

Variants of Uncertain Significance

The National Human Genome Research Institute defines VUS as a variant found in a patient’s genome for which it remains unclear as to whether a health condition is causing the variant. Oftentimes, such variants have very little information available due to their rarity.

In order to resolve VUS, Dr. Ellis recommended family segregation. “If the VUS appears to be de novo, you should test the parent because if they carry the gene, then it’s probably not the cause,” he said.

Dr. Ellis outlined several steps in resolving VUS.

For starters, clinicians should determine the phenotypic fit and run some ancillary tests. For example, in the case of Glu 1 abnormalities, one should consider conducting a spinal tap to determine whether the patient has cerebral spinal fluid before taking additional action.

In addition, Dr. Ellis recommends defining variant characteristics, as it becomes important in determining whether it is appropriate to take action because the majority of variances are benign.

“The take-home point is that you should not act clinically on a VUS unless you know what you’re doing,” he said. “I also disagree with the belief that VUS are rare — it’s just that they cause so much anxiety because we’re uncomfortable with this kind of testing.”

ORLANDO — “There are similarities between Alzheimer’s disease and epilepsy,” said Delia Marias Talos, MD, at a session of the annual meeting of the American Epilepsy Society (AES).

A Closer Look at the Brain

“Phosphorylated tau correlates with cognitive function and executive function recorded presurgery, but it looks like the generative changes are more associated with temporal lobe and aging.”

Alzheimer’s disease is a degenerative condition marked by progressive memory deficits and cognitive decline noted by amyloid plaques and a formation of neurofibrillary tangles resulting from tau hyperphosphorylation.

Epilepsy, on the other hand, is a multifactorial condition with causes ranging from metabolic disorders, structural defects, infections, genetic mutations, and autoimmune disorders. In addition, nearly 50% of all epileptic seizures are idiopathic in nature.

Dr. Talos, professor of neurology at the University of Pennsylvania Perlman School of Medicine in Philadelphia, and her team did not see neurofibrillary tangles in the presurgical brains of epilepsy patients they studied; however, they saw tau plaques. In the future, they seek to investigate the features that distinguish epilepsy from Alzheimer’s disease.

Toxic fragments are probably there because amyloid precursor protein is highly upregulated, she told conference attendees. “We hypothesized that amyloid plaque is cleared but not impaired in epilepsy.”

The prognosis looks comparatively worse for patients who have Alzheimer’s disease and comorbid epilepsy than for patients who have only epilepsy. In addition, Dr. Talos stated that seizures appear to have an additive effort on Alzheimer’s disease.
 

Fyn-disruptive Therapy

Marson Putra, MD, PhD, a neuroscientist and postdoctoral researcher at Iowa State in Ames, Iowa, presented on the potential impact of a novel fyn-tau interaction as an unexplored target for epileptogensis and epilepsy.

Dr. Putra studied whether fyn-tau interactions exist in epilepsy. In both Alzheimer’s disease and epilepsy, Fyn belongs to the Src family of nonreceptor tyrosine kinases (SFKs), which are involved in cell proliferation and migration. Fyn contains an SH3 domain, which serves as a target for tau’s proline-rich (PxxP) motif. Fyn phosphorylates tau, specifically at tyrosine residue Y18, making fyn-disruptive therapy worth exploring.

Dr. Putra shared several currently proposed mechanisms of action regarding the pathogenesis of the tau plaque. In the first theory, the tau protein assumes a closed conformation in its normal state, thereby concealing the PxxP motif. However, in the second theory, pathogenesis causes the tau protein to assume an open conformation in the disease state, exposing pAT8 sites and making them available to fyn phosphorylation. In the second scenario, which involves Alzheimer’s disease, the fyn-tau interaction still occurs in open conformation state and is thought to occur in the postsynaptic terminal of the dendritic spine.

To investigate the proposed disease-causing mechanisms, Dr. Putra and her team studied status epilepticus in a rodent model of status epilepticus (SE). They used proximity ligation assay to measure interactions between Fyn and tau. They found AT8 and Y18 Fyn and N-methyl-D-aspartate (NMDA) receptor activation in a rat model and increased Fyn interaction. In addition, neuronal nitric oxide synthase levels were elevated 24 hours post-status. When investigating the fyn activity and interactions in the human brain, they found fyn phosphorylation – something that had never been reported before.

From there, Dr. Putra’s team sought to answer whether manipulating fyn-tau interactions could modify epilepsy. To do so, they conducted an experiment using the pharmacological Fyn inhibitor sarcatinib (SAR) and found it modified dysregulated postsynaptic proteins 24 hours post-SE in rat models. Longer exposure also bore a positive effect on epileptic rats.

After treating epileptic rats with SAR for 7 weeks, Dr. Putra found that SAR therapy reduces convulsive seizures during 7 weeks post-SE in rats. Recruiting pharmacological Fyn inhibition sufficiently decreased Fyn-tau interaction, NR-PSD95 complex, and convulsive seizures in chronic epilepsy.

Ultimately, her findings showed that SE exacerbates fyn-tau interactions, with chronic epilepsy modeling showing sustained elevation. In addition, fyn-tau interactions mediate and sustain neuronal hyperexcitability in the epileptic population.

“The impact on clinical care will be bidirectional relevant therapeutic targets in epilepsy and Alzheimer’s disease,” Dr. Putra told the audience.
 

Trends in epilepsy comorbidity and mortality

The final presenter, University of Washington researcher Aaron del Pozo, PhD, explained the impact of early-onset Alzheimer’s disease on overall outcomes and epilepsy.

“Early-onset Alzheimer’s disease carries a high seizure risk that affects quality of life as well as mortality,” Dr. del Pozo said.

According to data published in the British Medical Journal in 2020, the number of patients with epilepsy who had degenerative disease of the central nervous system or vascular dementia and delirium increased by approximately 210% from 1999 to 2017. Cerebral palsy trailed in second place with malignant neoplasms increasing by 50%. Cerebrovascular disease­–related death in the epileptic population showed nearly negligible change, and ischemic heart disease and epilepsy decreased by approximately 25% and 15%, respectively. In addition, patients who have both epilepsy and Alzheimer’s disease are less likely to survive than patients who develop epilepsy after Alzheimer’s disease.

“We found that having epilepsy alone has decreased mortality, but having it in addition to other generative diseases of the central nervous system has a 200% increase in mortality,” Dr. del Pozo said.
