Febrile infection–related epilepsy syndrome (FIRES) is a catastrophic epileptic encephalopathy described as explosive onset of super refractory status epilepticus (SRSE) in previously healthy children. We describe electroencephalography (EEG) abnormalities in the hyperacute phase of FIRES, with the aim of contributing to the diagnostic characterization of a syndrome otherwise lacking specific biomarkers.

This is a retrospective single-center, case series of seven children with FIRES. Cases were identified from a Neurocritical Care database. Patient characteristics and clinical course were ...

Seizures in mesial temporal lobe epilepsy (MTLE) associated with hippocampal sclerosis are thought to develop with various latency intervals after an initial transient brain insult. To study seizure dynamics after an initial transient precipitating insult in a systematic fashion, we utilized continuous video–electroencephalography (EEG) monitoring after the induction of status epilepticus (SE) in a mouse MTLE model.

Continuous 24/7 video/telemetric hippocampal EEG recordings in the systemic pilocarpine MTLE mouse model.

After SE, we observed emerging seizures interfering ...

Given that only the free non–protein-bound concentration of an antiepileptic drug (AED) crosses the blood–brain barrier, entering the brain and producing an antiepileptic effect, knowledge and measurement of the free drug fraction is important. Such data are sparse, particularly for newer AEDs, and have arisen from the use of disparate methodologies and settings over the past six decades. We report on the protein binding of 25 AEDs that are available for clinical use, along with two pharmacologically ...

To ascertain possible determinants of carbamazepine (CBZ)– and oxcarbazepine (OXC)–induced hyponatremia in a large cohort of people with epilepsy.

We collected data on serum sodium levels in people with epilepsy who were attending a tertiary epilepsy center while on treatment with CBZ or OXC. We defined hyponatremia as Na+ ≤134 mEq/L and severe hyponatremia as Na+ ≤128 mEq/L.

We identified 1,782 people who had used CBZ (n = 1,424) or OXC (n = 358), of whom 50 ...

Variants in neuronal voltage-gated sodium channel α-subunits genes SCN1A, SCN2A, and SCN8A are common in early onset epileptic encephalopathies and other autosomal dominant childhood epilepsy syndromes. However, in clinical practice, missense variants are often classified as variants of uncertain significance when missense variants are identified but heritability cannot be determined. Genetic testing reports often include results of computational tests to estimate pathogenicity and the frequency of that variant in population-based databases. The objective of this work was ...

To evaluate dose–response relationship of BGG492 as add-on therapy to 1–3 antiepileptic drugs in patients with partial-onset seizures and to investigate safety and tolerability of BGG492.

This was a 12-week, randomized, double-blind, placebo-controlled, phase II dose-titration study (core study) with a 30-week, flexible-dose, open-label extension. In the core study, patients were randomized (1:2) to placebo or BGG492 100 mg t.i.d. in cohort 1, and in cohort 2 patients were randomized (1:4) to placebo or BGG492 150 mg t.i.d. On ...
