Mechanisms of video-game epilepsy.

abstract：PURPOSE:Benign partial epilepsy (BPE) in childhood is characterized by the occurrence of interictal stereotyped focal spikes with variable localization in the EEG. Children with BPE often exhibit neuropsychological deficits. It is unclear whether a correlation exists between these deficits and the localization of spike...

abstract：PURPOSE:The multidrug resistance (mdr) gene family encodes the drug transport macromolecule P-glycoprotein (P-gp), which contributes to the functionality of the blood-brain barrier. Recent evidence suggests that P-gp-mediated drug extrusion may play a facilitatory role in refractory epilepsy. We investigated the region...
