Pathogenic variants involving the CDKL5 gene result in a severe epileptic encephalopathy, often later presenting with features similar to Rett syndrome. Cardinal features of epilepsy in the CDKL5 disorder include early onset at a median age of 6 weeks and poor response to antiepileptic drugs. The ketogenic diet (KD) was first introduced in the 1920s as a treatment option for refractory epilepsy in children. This study investigated use of the KD in the CDKL5 disorder and its ...

Proper assessment and early identification of depressive symptoms are essential to initiate treatment and minimize the risk for poor outcomes in youth with epilepsy (YWE). The current study examined the predictive utility of the Neurological Disorders Depression Inventory-Epilepsy for Youth (NDDI-E-Y) and the Neuro-QOL Depression Short Form (Neuro-QOL SF) in explaining variance in overall depressive symptoms and specific symptom clusters on the gold standard Children’s Depression Inventory-2 (CDI-2).

To evaluate acute and long-term effects of intravenous brivaracetam (BRV) and BRV + diazepam (DZP) combination treatment in a rat model of self-sustaining status epilepticus (SSSE).

Rats were treated with BRV (10 mg/kg) 10 min after initiation of perforant path stimulation (PPS) as early treatment; or BRV (10–300 mg/kg), DZP (1 mg/kg), or BRV (0.3–10 mg/kg) + DZP (1 mg/kg) 10 min after the end of PPS (established SSSE). Seizure activity was recorded electrographically for 24 h ...

The objective of this (trial-based) economic evaluation was, from a societal perspective, to compare the cost-effectiveness of a multicomponent self-management intervention (MCI) with care as usual (CAU) in adult patients with epilepsy over a 12-month period.

In a randomized-controlled trial, participants were randomized into intervention or CAU group. Adherence, self-efficacy (Epilepsy Self-Efficacy Scale [ESES]), quality-adjusted life years (QALYs), healthcare costs, production losses, and patient and family costs were assessed at baseline and during the 12-month study period. ...

The mutant γ-aminobutyric acid type A (GABA_A) receptor γ2(Q390X) subunit (Q351X in the mature peptide) has been associated with the epileptic encephalopathy, Dravet syndrome, and the epilepsy syndrome genetic epilepsy with febrile seizures plus (GEFS+). The mutation generates a premature stop codon that results in translation of a stable truncated and misfolded γ2 subunit that accumulates in neurons, forms intracellular aggregates, disrupts incorporation of γ2 subunits into GABA_A receptors, and affects trafficking of partnering α and β ...

Mutations of the KCNQ2 gene, which encodes the K_v7.2 subunit of voltage-gated M-type potassium channels, have been associated with epilepsy in the neonatal period. This developmental stage is unique in that the neurotransmitter gamma aminobutyric acid (GABA), which is inhibitory in adults, triggers excitatory action due to a reversed chloride gradient.

To examine whether KCNQ2-related neuronal hyperexcitability involves neonatally excitatory GABA, we examined 1-week-old knockin mice expressing the K_v7.2 variant p.Tyr284Cys (Y284C).

Brain slice electrophysiology revealed elevated ...
