Abstract

Objective

The overall prognosis of benign convulsions associated with mild gastroenteritis (CwG) is favorable, and the incidence of afebrile seizure recurrence with or without gastroenteritis (ASwGI and ASwoGI, respectively) is low. In this study we investigated the prognostic factors associated with afebrile seizure (AS) relapse after the first CwG episode.

Methods

A hospital-based cohort with an initial CwG episode from January 2012 to October 2019 was followed for at least 19 months. The relapse types were divided into ASwGI and ASwoGI. Logistic regression analysis ...

Abstract

Objective

Classical clinical characteristics associated with successful or unsuccessful extubation are unreliable in neurocritically ill patients, and attempts to predict successful extubation in this context have failed. We aimed to investigate the frequency of mechanical ventilation (MV) in adult patients in status epilepticus (SE) and its clinical associations, to identify predictors at SE onset of prolonged postictal MV, and to determine the associated outcomes with prolonged MV.

Methods

From 2012 to 2018, SE patients treated in intensive care units at a Swiss academic ...

Abstract

Objective

To identify functional and structural alterations in language networks of people with temporal lobe epilepsy (TLE), who frequently present with naming and word-finding difficulties.

Methods

Fifty-five patients with unilateral TLE (29 left) and 16 controls were studied with auditory and picture naming functional magnetic resonance imaging (fMRI) tasks. Activation maxima in the left posterobasal temporal lobe were used as seed regions for whole-brain functional connectivity analyses (psychophysiological interaction). White matter language pathways were investigated using diffusion tensor imaging and neurite orientation dispersion and ...

Abstract

Objectives

We aimed to determine the incidence of periodic and rhythmic patterns (PRP), assess the interrater agreement between electroencephalographers scoring PRP using standardized terminology, and analyze associations between PRP and electrographic seizures (ES) in critically ill children.

Methods

This was a prospective observational study of consecutive critically ill children undergoing continuous electroencephalographic monitoring (CEEG). PRP were identified by one electroencephalographer, and then two pediatric electroencephalographers independently scored the first 1-h epoch that contained PRP using standardized terminology. We determined the incidence of PRPs, ...

Abstract

Objective

We describe for the first time clinical characteristics in a series of 20 pre-surgically investigated patients with mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE) who were operated on in our epilepsy center. We aimed to better diagnose this entity and help surgical planning.

Methods

Data on 20 patients with histologically confirmed MOGHE were retrospectively evaluated as to age at epilepsy onset and operation, seizure semiology, magnetic resonance imaging (MRI) localization, electroencephalography (EEG) patterns, extent of the operative resection, and postoperative ...

Abstract

Objective

To report long-term post hoc efficacy and safety data from 10 US study sites from an open-label Phase 3 study of adjunctive cenobamate (NCT02535091).

Methods

Patients with uncontrolled focal seizures taking stable doses of 1–3 antiseizure medications (ASMs) were administered increasing daily doses of cenobamate (12.5, 25, 50, 100, 150, 200 mg/day) over 12 weeks at 2-week intervals (target dose = 200 mg/day). Further increases to 400 mg/day by 50-mg/day increments biweekly were allowed during the maintenance phase. Dose adjustments of cenobamate and concomitant ASMs were allowed. ...

Abstract

Objective

To report post hoc results on how adjustments to baseline antiseizure medications (ASMs) in a subset of study sites (10 US sites) from a long-term, open-label phase 3 study of adjunctive cenobamate affected tolerability, efficacy, and retention.

Methods

Patients with uncontrolled focal seizures taking stable doses of one to three ASMs were administered increasing doses of cenobamate (12.5, 25, 50, 100, 150, 200 mg/day) over 12 weeks at 2-week intervals (target dose = 200 mg/day). Further increases to 400 mg/day by 50 mg/day biweekly increments were allowed during ...

Summary

Objectives

Benzodiazepines are the standard of care for the management of sustained seizure emergencies, including status epilepticus (SE) and seizure clusters. Seizure clusters are a variably defined seizure emergency wherein a patient has multiple seizures above a baseline rate, with intervening periods of recovery, distinguishing clusters from SE. Although these seizure emergencies are phenotypically distinct, the precise pathophysiological and mechanistic differences between SE and seizure clusters are understudied. Emergency-specific preclinical models may differentiate the behavioral and pathological mechanisms that are acutely ...
