Summary

Objective

To determine annual incidence, etiology, severity, and short‐ and long‐term mortality of first‐time, nonanoxic status epilepticus (SE) in adults in a population‐based retrospective cohort study.

Methods

We systematically identified all episodes of SE in the year 2014 on the island of Funen. Patients with SE due to anoxia, patients with recurrent SE, and patients <18 years old were excluded. Nonconvulsive SE in coma was diagnosed according to the Salzburg criteria. Etiology, semiology, modified Rankin Scale (mRS) at discharge, survival, and the Status Epilepticus ...

Summary

Objective

Low‐frequency fiber‐tract stimulation has been shown to be effective in treating mesial temporal lobe epilepsies through activation of the hippocampal commissure in rodents and human patients. The corpus callosum is a major pathway connecting the two hemispheres of the brain; however, few experiments have documented corpus callosum stimulation. The objective is to determine the efficacy of corpus callosum stimulation at low frequencies to suppress cortical seizures.

Methods

4‐Aminopyridine was injected in the primary motor cortex of 24 rats under anesthesia. Recording electrodes ...

Summary

Objective

In this study, we seek to analyze the determinants of the intracranial electroencephalography seizure onset pattern (SOP) and the impact of the SOP in predicting postsurgical seizure outcome.

Methods

To this end, we analyzed 820 seizures from 252 consecutive patients explored by stereo‐electroencephalography (total of 2148 electrodes), including various forms of focal refractory epilepsies. We used a reproducible method combining visual and time‐frequency analyses.

Results

We described eight SOPs: low‐voltage fast activity (LVFA), preictal spiking followed by LVFA, burst of polyspikes followed by LVFA, ...

Summary

Objective

The definition of drug‐resistant epilepsy (DRE) affects case identification and treatment, and impacts prevalence or incidence estimates and health burden estimation in epidemiology. The objective of this systematic review is to evaluate the consistency between definitions of DRE in the literature and the official definition in the International League Against Epilepsy (ILAE) guidelines, and to estimate the incidence, prevalence, and risk factors for DRE.

Methods

MEDLINE and EMBASE were searched for observational studies of DRE published between January 1980 and July 2015. ...

Summary

Objective

Stevens‐Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare and potentially fatal adverse skin reactions that are most commonly triggered by certain medications. One class of medications that has been highly associated with SJS/TEN reactions is antiepileptic drugs (AEDs). We sought to quantify the risk of SJS/TEN associated with AEDs as a class, as well as individual AEDs, in the United States.

Methods

An analysis was performed of the US Food and Drug Administration Adverse Event Reporting System (FAERS) from July ...

Summary

Objective

Onset of epilepsy before 2 years of age is associated with poor cognitive outcome; however, the natural course of the range of epilepsies that occur at this age is unknown. The aim of this prospective community‐based study was to investigate the neuropsychological development of infants with newly diagnosed epilepsy longitudinally and to identify the clinical factors that predict long‐term impairment.

Methods

Sixty‐six infants <24 months of age were enrolled in the baseline phase of this study; 40 were seen again at 1‐year follow‐up and ...

Summary

Objective

This retrospective study was designed to assess the impact of corpus callosotomy (CC) in patients with intractable West syndrome (WS) without lesions on magnetic resonance imaging (MRI).

Methods

This study involved 56 patients with WS who underwent CC between January 2000 and December 2014. Seizure outcomes and changes in psychomotor development were analyzed.

Results

Mean age at the onset of epilepsy and at the time of CC was 5.1 and 22.6 months, respectively. Mean duration of epilepsy before CC was 17.6 months. Video‐electroencephalography (EEG) monitoring showed ...

Summary

Objective

The majority of the 65 million people worldwide with epilepsy live in low‐ and middle‐income countries. Many of these countries have inadequate resources to serve the large patient population affected by epilepsy. Panama is a middle‐income country that currently has only 2 facilities that can provide basic epilepsy services and no epilepsy surgery services. To address this need, a group of Panamanian physicians partnered with U.S. epilepsy health care providers to test a hybrid epilepsy surgery program, combining resources and ...

Summary

Objective

After the failure of the first antiepileptic drug (AED) at doses > 50% defined daily dose (DDD), there are three options for patients with epilepsy: combination therapy, alternative therapy, and increased dosage of the first AED. However, present studies have not provided evidence for which option is best. Therefore, we conducted this retrospective observational cohort study to compare the effects of three treatment schedules.

Methods

Patients diagnosed with newly diagnosed epilepsy at the epilepsy clinic of West China Hospital between August 2006 ...

Summary

Objectives

Developmental encephalopathic epilepsies (DEEs) are characterized by refractory seizures, disability, and early death. Opportunities to improve care and outcomes focus on West syndrome/infantile spasms (WS/IS). Lennox‐Gastaut syndrome (LGS) is almost as common but receives little attention. We examined initial presentations of DEEs and their evolution over time to identify risk and indicators of developing LGS.

Methods

Data are from the Connecticut Study of Epilepsy, a prospective, longitudinal study of 613 children with newly diagnosed epilepsy recruited in 1993‐1997. Central review of medical ...
