Dysfunction in the gene SCN2A, which encodes voltage-gated sodium channel Nav1.2, is strongly associated with neurodevelopmental disorders including autism spectrum disorder and intellectual disability (ASD/ID).

Intermittent fasting enhances neural bioenergetics, is neuroprotective, and elicits antioxidant effects in various animal models. There are conflicting findings on seizure protection, where intermittent regimens often cause severe weight loss resembling starvation which unsustainable long-term. Therefore, we tested whether a less intensive regimen such as time-restricted feeding (TRF) may confer protection.

This preface introduces the Journal of Neurochemistry Special Issue on Advances in Epilepsy Research. is a devastating disease characterized by recurrent seizures. Despite addition numerous therapeutics over last few decades epilepsy patients resistant to standard care treatments remains stubbornly high. highlights clear unmet clinical need and importance new research into this disease. One major advance two has been recognition that genetic factors play significant role underlying pathogenesis epilepsy. Much our insights pathogenic mechanisms come from genes encode ion channels. In issue, there are up-to-date reviews discussing caused variation HCN channels, voltage-dependent sodium calcium GABA

Abstract Objective To identify key factors influencing the therapeutic efficacy of ketogenic diet (KD) for children with drug‐resistant epilepsy and elucidate their interconnected relationships to optimize clinical practice. Methods Participants were selected from receiving KD treatment at West Second University Hospital Sichuan September 2015 October 2023. Clinical pre‐KD post‐KD (at third month) analyzed systematically using an analytical framework. Descriptive analyses, univariate multivariate regression analyses performed entire cohort subgroups genetic non‐genetic (i.e., structural unknown) etiologies. Thereby, most significant predictors identified each relevant dependent variable. Path analysis diagrams used visual representation. Results Of 156 patients, etiology was prevalent (38.5%). In subgroup, channelopathies predicted lower baseline seizure frequency increased chance freedom KD. Frequent seizures complex history anti‐seizure medications (ASMs) severe psychomotor abnormalities. Younger age initiation benefited improvement. likelihood post‐KD. Concurrent use multiple ASMs helped achieve ≥50% reduction. Boys more likely experience A correlation found between reduction improvement in both subgroups. Delayed (longer duration start) related a greater number used, infrequent seizures, older onset. addition, patients had delayed Significance Children display pronounced characteristics epileptic encephalopathy. Early intervention is crucial channelopathies, notably SCN1A variants. For other cases, alongside diverse may improve control developmental outcomes. However, patient population benefiting early tends start later, urging re‐evaluation decision‐making paradigms.
