Sleep magnetoencephalography enhances detection and source imaging of seizures and fast oscillations in focal cortical dysplasia

open access: yesEpilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) causes drug‐resistant epilepsy requiring presurgical evaluation. Invasive electroencephalographic (EEG) studies demonstrate that sleep modulates epileptic activity, including interictal epileptiform discharges (IEDs), fast oscillations (FOs) in the beta (14–40 Hz) and gamma (40–80 Hz) frequency bands ...

Interictal and seizure‐onset scalp electroencephalographic patterns in malformations of cortical development

open access: yesEpilepsia, EarlyView.
Abstract Objective Malformations of cortical development (MCDs) are a frequent cause of drug‐resistant epilepsy and a common indication for resective epilepsy surgery. As magnetic resonance imaging (MRI) lacks sensitivity for subtle MCDs, supplemental diagnostic tools are needed.

Arterial spin labeling performs comparably to 2‐[18F]fluoro‐2‐deoxy‐D‐glucose positron emission tomography for presurgical evaluation in pediatric lesional epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to test whether arterial spin labeling (ASL) performs comparably to 2‐[18F]fluoro‐2‐deoxy‐D‐glucose positron emission tomography (FDG‐PET), the mainstay functional imaging technique, in pediatric lesional epilepsy, while avoiding radiotracer exposure and additional sedation.

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain

open access: yesEpilepsia, EarlyView.
Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...
