Overview
Epilepsy is frequently associated with cognitive and attentional disorders. Several studies have pointed out that there are modifications of brain activity in resting state during peri-ictal period in EEG and functional MRI. However, to date, no study has assessed the changes in attentional control after a seizure. The investigators hypothesize that a localized discharge is associated with a disorganization of the networks engaged in attentional control. In this regard, the investigators propose a prospective longitudinal study assessing the changes in attentional control after a focal seizure.
