Cortical resections in epilepsy surgery tend to involve multiple lobes in children, compared to adults, partly due to underlying pathology. Oligodendroglia-like cells (OLCs) have been observed in surgical specimens from children with pharmacoresistant epilepsy. We hypothesize that OLCs recruit multiple-lobe epileptogenic zones in pediatric pharmacoresistant focal epilepsy.

We examined the surgical specimens from 30 children who underwent epilepsy surgery (1.8- to 16.9-years-old; mean age 9.7 years). Immunohistochemical assays of OLCs were performed using Olig2, which is a ...

Interictal [18F]fluorodeoxyglucose–positron emission tomography (FDG-PET) is used in the presurgical evaluation of patients with drug-resistant focal epilepsy. We aimed at clarifying its relationships with ictal high-frequency oscillations (iHFOs) shown to be a relevant marker of the seizure-onset zone.

We studied the correlation between FDG-PET and epileptogenicity maps in an unselected series of 37 successive patients having been explored with stereo-electroencephalography (SEEG).

At the group level, we found a significant correlation between iHFOs and FDG-PET interictal hypometabolism only ...

Epilepsy and autism spectrum disorder (ASD) often occur together in the same individual. However, it remains unknown whether siblings of children with ASD have an increased risk of epilepsy and vice versa. This study determines the risk of ASD and epilepsy among younger siblings of children with ASD and epilepsy.

The study included all children born in Denmark between January 1, 1980 and 31 December 2006 who participated in follow-up until December 31, 2012 (1,663,302 children). We ...

In vivo studies of epilepsy typically use prolonged status epilepticus to generate recurrent seizures. However, reports on variable status duration have found discrete differences in injury after 40–50 min of seizures, suggesting a pathophysiologic sensitivity to seizure duration. In this report we take a multivariate cluster analysis to study a short duration status epilepticus model using in vivo 7T magnetic resonance spectroscopy (MRS) and histologic evaluation.

The Hellier Dudek model was applied with 45 min of status ...

To explore the influence of several estimates of family socioeconomic status on the long-term clinical course and social outcomes of children with epilepsy.

The Nova Scotia childhood epilepsy cohort is population based and includes all children in this Canadian province who developed epilepsy between 1977 and 1985. Eligible patients had ≥10 years of follow-up. Children with childhood absence epilepsy were excluded. Total family income at seizure onset was assessed at seizure onset and classified as “poor” (first quintile), ...
