Since the first antiseizure medication (ASM) was introduced in 1857, more than 30 medications have been approved by the United States Food and Drug Administration (FDA) for the treatment of epilepsy. However, limitations in efficacy and tolerability have led to one-third of patients suffering from uncontrolled seizures. Recent advances in genetics, disease modeling, high-throughput target-based and phenotype-based screening, study design, and identification of novel mechanisms of action or routes of delivery have resulted in more than 200 therapeutics currently under development in the epilepsy pipeline. This study discusses near-to-market drugs in advanced clinical development, with select drugs in earlier stages. Background regarding mechanisms, animal studies, pharmacokinetics, pharmacodynamics, efficacy, tolerability, and safety data are provided for each drug when available.

INTRODUCTION/BACKGROUND:This study investigates whether midlife cortisol levels predict Alzheimer's disease (AD) biomarker burden 15 years later, with particular attention to sex differences and menopausal status. METHODS:F]Flortaucipir) positron emission tomography (PET) imaging conducted 15 years later. We performed multivariable regression analyses adjusted for confounders including, apolipoprotein E4 (APOE4) status. RESULTS:Elevated midlife cortisol correlated with increased amyloid deposition, specifically in post-menopausal women, predominantly in posterior cingulate, precuneus, and frontal-lateral regions (p < 0.05). No significant associations were observed with tau burden or in males. DISCUSSION/CONCLUSIONS:These findings reveal post-menopausal women with high midlife cortisol are at increased risk of AD. Results highlight the importance of identifying early risk factors when biomarkers are detectable but cognitive impairment is absent. HIGHLIGHTS/CONCLUSIONS:High midlife cortisol is linked to increased amyloid deposition in post-menopausal women. Cortisol showed no association with tau pathology. Post-menopausal hormone changes may amplify cortisol's effects on amyloid.

OBJECTIVES/BACKGROUND/OBJECTIVE:This study was undertaken to synthesize evidence on the benefits and harms of behavioral interventions for migraine prevention in children and adults. The efficacy and safety of behavioral interventions for migraine prevention have not been tested in recent systematic reviews. METHODS:An expert panel including clinical psychologists, neurologists, primary care physicians, researchers, funders, individuals with migraine, and their caregivers informed the scope and methods. We searched MEDLINE, Embase, PsycINFO, PubMed, the Cochrane Database of Systematic Reviews, clinicaltrials.gov, and gray literature for English-language randomized trials (January 1, 1975 to August 24, 2023) of behavioral interventions for preventing migraine attacks. Primary outcomes were migraine/headache frequency, migraine disability, and migraine-related quality of life. One reviewer extracted data and rated the risk of bias, and a second verified data for completeness and accuracy. Data were synthesized with meta-analysis when deemed appropriate, and we rated the strength of evidence (SOE) using established methods. RESULTS:For adults, we included 50 trials (77 publications, N = 6024 adults). Most interventions were multicomponent (e.g., cognitive behavioral therapy [CBT], biofeedback, relaxation training, mindfulness-based therapies, and/or education). Most trials were at high risk of bias, primarily due to possible measurement bias and incomplete data. For adults, we found that any of three components (CBT, relaxation training, mindfulness-based therapies) may reduce migraine/headache attack frequency (SOE: low). Education alone that targets behavior may improve migraine-related disability (SOE: low). For three other interventions (biofeedback, acceptance and commitment therapy, and hypnotherapy), evidence was insufficient to permit conclusions. We also found that mindfulness-based therapies may reduce migraine disability more than education, and relaxation + education may improve migraine-related quality of life more than propranolol (SOE: low). For children/adolescents, we included 13 trials (16 publications, N = 1444 children), but the evidence was only sufficient to conclude that CBT + biofeedback + relaxation training may reduce migraine attack frequency and disability more than education alone (SOE: low). CONCLUSION/CONCLUSIONS:Results suggest that for adults, CBT, relaxation training, and mindfulness-based therapies may each reduce the frequency of migraine/headache attacks, and education alone may reduce disability. For children/adolescents, CBT + biofeedback + relaxation training may reduce migraine attack frequency and disability more than education alone. Evidence consisted primarily of underpowered trials of multicomponent interventions compared with various types of control groups. Limitations include semantic inconsistencies in the literature since 1975, differential usage of treatment components, expectation effects for subjectively reported outcomes, incomplete data, and unclear dosing effects. Future research should enroll children and adolescents, standardize intervention components when possible to improve reproducibility, consider smart study designs and personalized therapies based on individual characteristics, use comparison groups that control for expectation, which is a known challenge in behavioral trials, enroll and retain larger samples, study emerging digital and telehealth modes of care delivery, improve the completeness of data collection, and establish or update clinical trial conduct and reporting guidelines that are appropriate for the conduct of studies of behavioral therapies.

BACKGROUND AND OBJECTIVES/UNASSIGNED:Neurosarcoidosis poses a diagnostic and management challenge due to its rarity, phenotypic variability, and lack of randomized controlled studies to guide treatment selection. Recommendations for management based on expert opinion are useful in clinical practice and provide a framework for designing prospective studies. METHODS/UNASSIGNED:In this Delphi survey study, specialists with experience in managing patients with neurosarcoidosis were invited to anonymously complete 2 surveys about key elements of evaluation, diagnosis, treatment, monitoring, and long-term management of neurosarcoidosis. Expert consensus recommendations were adopted if >80% threshold of agreement was reached. RESULTS/UNASSIGNED:Of the 41 invited expert clinicians across the United States, 32 (78%) participated in the study. All round 1 respondents self-identified as neuroimmunologists (except for 1 pulmonologist). Consensus was reached regarding the need to consider neurosarcoidosis phenotype and severity to guide the choice of initial immunosuppression in both the acute (relapse) and maintenance phases. Experts endorsed the use of TNF-α inhibitors as first-line agents in selected phenotypes with poor prognosis. Neuroimaging was recommended to complement clinical surveillance for treatment response. DISCUSSION/UNASSIGNED:There was agreement on several key issues, most importantly on the need to consider neurosarcoidosis phenotype and severity when deciding initial treatment. No consensus was achieved on the dosing and duration of specific immunosuppressants, nor regarding the management of the peripheral nervous system manifestation of neurosarcoidosis. These topics warrant further investigation.

OBJECTIVE:To report interim data from an ongoing, open-label extension (OLE) of a Phase 2b study (X-TOLE) of azetukalner in adults with focal onset seizures (FOS) receiving 1-3 antiseizure medications. METHODS:Eligible participants enrolled in the 7-year OLE at 20 mg azetukalner once daily with food. Long-term seizure outcomes included median percentage change (MPC) in monthly (28 days) FOS frequency from the double-blind phase (DBP) baseline and achievement of ≥50%, ≥75%, ≥90%, and 100% seizure reductions. RESULTS:285 participants completed the DBP, and 275 (96.5%) enrolled in the OLE. At the 24-month interim analysis (September 5, 2023), 182 participants had been treated for ≥12 months and 165 for ≥24 months; 152 (55.3%) continued in the study. The median (range) treatment duration in the OLE was 26.3 (0.1-46.6) months. MPC reduction was 83.2% at 24 months in the OLE vs. DBP baseline. For all participants who entered the OLE, 56.4% (155/275) and 44.4% (122/275) achieved a ≥50% seizure reduction, 28.4% (78/275) and 19.6% (54/275) achieved a ≥90% seizure reduction, and 22.2% (61/275) and 14.9% (41/275) achieved seizure freedom (100% seizure reduction) for any consecutive ≥6- and ≥12-month period, respectively. For those who reached ≥24 months in the OLE, seizure freedom was achieved by 34.5% (57/165) and 23.6% (39/165) for any consecutive ≥6- and ≥12-month period, respectively. The majority of treatment-emergent adverse events (TEAEs) were mild or moderate. The most common TEAEs were dizziness (21.8%), headache (15.3%), coronavirus infection (15.3%), somnolence (12.7%), fall (12.7%), and memory impairment (10.9%). Serious AEs were reported in 35 (12.7%) participants. SIGNIFICANCE/CONCLUSIONS:The efficacy demonstrated by azetukalner in reducing FOS seizure frequency in the DBP was sustained in this interim analysis. Azetukalner was generally well tolerated, with no new safety signals compared to the DBP. These data suggest sustained long-term efficacy and safety of azetukalner in a difficult-to-treat population. PLAIN LANGUAGE SUMMARY/CONCLUSIONS:This long-term study assessed the safety and efficacy of azetukalner to treat focal seizures. Patients taking azetukalner daily with food for about 2 years had far fewer focal seizures with azetukalner than before taking the medication. For those who had been treated for 24 months, about a third were seizure-free for a consecutive 6-month period, and about a quarter were seizure-free for a consecutive 12-month period. Most side effects were mild or moderate, and these included dizziness, headache, and somnolence (sleepiness).

We here present evidence-based guidelines for the pharmacological treatment of migraine. These guidelines, created by the Italian Society for the Study of Headache and the International Headache Society, aim to offer clear, actionable recommendations to healthcare professionals. They incorporate evidence-based recommendations from randomized controlled trials and expert-based opinions. The guidelines follow the Grading of Recommendations, Assessment, Development and Evaluation approach for assessing the quality of evidence. The guideline development involved a systematic review of literature across multiple databases, adherence to Cochrane review methods, and a structured framework for data extraction and interpretation. Although the guidelines provide a robust foundation for migraine treatment, they also highlight gaps in current research, such as the paucity of head-to-head drug comparisons and the need for long-term outcome studies. These guidelines serve as a resource to standardize migraine treatment and promote high-quality care across different healthcare settings.

Severe brain injury can result in disorders of consciousness (DoC), including coma, vegetative state/unresponsive wakefulness syndrome, and minimally conscious state. Improved emergency and trauma medicine response, in addition to expanding efforts to prevent premature withdrawal of life-sustaining treatment, has led to an increased number of patients with prolonged DoC. High-quality bedside care of patients with DoC is key to improving long-term functional outcomes. However, there is a paucity of DoC-specific evidence guiding clinicians on efficacious bedside care that can promote medical stability and recovery of consciousness. This Viewpoint describes the state of current DoC bedside care and identifies knowledge and practice gaps related to patient care with DoC collated by the Care of the Patient in Coma scientific workgroup as part of the Neurocritical Care Society's Curing Coma Campaign. The gap analysis identified and organized domains of bedside care that could affect patient outcomes: clinical expertise, assessment and monitoring, timing of intervention, technology, family engagement, cultural considerations, systems of care, and transition to the post-acute continuum. Finally, this Viewpoint recommends future research and education initiatives to address and improve the care of patients with DoC.

The mechanisms behind comorbid symptoms of depression in persons with epilepsy (PWE) remain largely unknown. Our study aimed to learn whether seizures moderate fluctuations in depressive symptoms in PWE when controlling for preictal symptoms of depression. We enrolled 57 adult PWE admitted to the New York University (NYU) Langone Epilepsy Monitoring Unit (EMU) from 2021 to 2024. Thirty-seven participants had a seizure. Twenty of the admitted patients did not have seizures during the admission period and therefore served as controls. All participants were seizure free for > 7 days prior to participation. Upon admission, all participants completed the Montgomery-Asberg Depression Rating Scale (MADRS) to evaluate baseline mood. The MADRS was repeated acutely (4-24 h post seizure or admission) and subacutely (2-7 days post seizure or discharge) for both groups. Linear regression models revealed that individuals with higher baseline MADRS scores (indicating higher depressive symptoms) experienced worse mood acutely post-seizure, while lower baseline MADRS scores were associated with acute mood improvement (R² = 0.59, p < 0.001). Experiencing a seizure was not associated with subacute mood outcomes, which were instead driven by acute mood state (R² = 0.56, p < 0.001). In conclusion, we found that seizures exacerbate pre-ictal depressive symptoms and that post-ictal depressive symptoms persist up to 7 days after seizure resolution. This study may provide evidence for a bidirectional relationship and demonstrate a vicious cycle between depression and epilepsy.
