The study was led by the international NORSE Institute LTO Working Group. First, literature describing the LTO of NORSE survivors was identified using a PubMed search and summarized to identify knowledge gaps. Subsequently, a consensus-building process was performed to prioritize and rank important LTO domains for further research. The prioritization of LTO domains was qualitative, enabling the expert panel to generate ideas, share opinions, and provide reasons for the rankings. A second round took place to allow expansion and agreement regarding specific details for each domain. Outcomes were classified into eight main domains: (1) Function: Neuropsychological, Neurological (other than seizures), and Psychiatric (mood and behavior); (2) Quality of Life; (3) Epilepsy; (4) Nonneurological (medical); (5) Social; (6) Caregiver Burden; (7) Long-Term Mortality; and (8) Health Care System Impact. In addition, the working group suggested obtaining outcome measures for each domain at 6 months and 1 year after discharge and annually thereafter until stability has been reached. There are no currently established time frames set for when LTO in NORSE begin or plateau, and previously there existed no consensus regarding which LTO should be considered. This consensus process identifies and recommends NORSE LTO domains that should be considered in future research studies to provide more consistent results that can be compared between studies. Survivors of NORSE should be evaluated serially and at fixed points over time to maximize our understanding of the recovery trajectory for all LTO domains.

Continuous EEG monitoring of critically ill patients has further refined the classification of NCSE into two main categories: with coma and without coma. Hypnotic, soporific or somniferous epileptic seizures do not exist. On the contrary, patients usually awaken when seizures occur during sleep, and their eyes remain open during ASE. Excessive sleepiness and coma alone are not ictal signs but are observed in the postictal phase of convulsive seizures. On the other hand, excessive sleepiness evolving into coma is a cardinal sign of metabolic/toxic encephalopathies with triphasic waves evolving to burst suppression patterns and ultimately to cerebral inactivity and death. NCSE alone does not directly cause coma. Comas are related to the underlying etiology, patient age and comorbidities, as well as the administration of intravenous sedative drugs to control epileptic seizures. In cases of severe brain injury, NCSE can explain the failure to awaken after the withdrawal of anesthetics and is only an aggravating factor of the neurological condition. In typical ASE, which is characterized by sustained, rhythmic, bilateral, synchronous and unreactive discharges with evolving spatiotemporal patterns (the best example of NCSE), there is no vigilance impairment. This contrasts with metabolic/toxic encephalopathies, which exhibit monomorphic generalized periodic discharges in which patients may become comatose and die.

The JME plus tremor subjects had higher numbers of previous childhood absence epilepsy (n = 6/31 [19.4%]), interictal epileptiform discharges (n = 30/31 [96.8%]), photosensitivity (n = 8/31 [25.8%]), and psychiatric comorbidities (n = 12/31 [38.7%]). Six of 31 (19.4%) individuals with JME plus tremor had giant SEPs (1/30, 3.3% with JME; p = .05, chi-squared test). The clinical features and decreased sensorimotor inhibition in the JME plus tremor group suggest that tremor might be a marker of disease severity rather than an epiphenomenon of VPA exposure.</p>","PeriodicalId":11768,"journal":{"name":"Epilepsia","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143002218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High doses of sodium channel blockers are typically used to treat SCN8A-DEE caused by gain-of-function (GoF) variants. However, seizures are often drug resistant, and only a few patients achieve seizure freedom. In this retrospective study, the effect of cenobamate was assessed in patients with SCN8A-DEE.</p><p><strong>Methods: </strong>Across multiple centers and through collaborations with SCN8A patient advocacy organizations, patients with SCN8A-DEE treated with cenobamate for ≥6 months were identified. Data were obtained from patients' caregivers or treating physicians through a (Research Electronic Data Capture) REDCap survey. The functional effect of the SCN8A variants was obtained from the literature or assessed by prediction tools.</p><p><strong>Results: </strong>Twelve patients (3-25 years of age (median 8 years), 9 females) with presumed GoF SCN8A variants were treated with cenobamate for a mean period of 17 months (range 6-42 months). Countable motor seizures were meaningfully reduced in 10 of 12 patients (83%). Six patients experienced a seizure reduction above 70%, of which two achieved seizure freedom. In addition, two patients achieved a reduction in seizures ranging between 50% and 70%. An increase in seizure-free days per patient was also reported. Rescue medication was decreased in six of seven patients (85%) in need. Furthermore, 80% of patients reported non-seizure-related improvements, which included increased alertness, better sleep, and improved muscle tone. Adverse effects were reported by 50% of patients, and half resolved spontaneously or through the reduction of concomitant antiseizure medications.</p><p><strong>Significance: </strong>Our data suggest that cenobamate is a promising and safe treatment for SCN8A-DEE, even during early childhood. As a potential precision approach to treatment, cenobamate significantly reduced seizure burden and improved non-seizure-related symptoms. These positive outcomes may also be achieved in patient cohorts with GoF variants in other voltage-gated sodium channel genes.</p>","PeriodicalId":11768,"journal":{"name":"Epilepsia","volume":" ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142983044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
