National Study on the Interest of EEG-fMRI in the Presurgical Evaluation of Partial Epilepsies Drug

University Hospital, Lille102 enrolled

Overview

The main goal of this study is to evaluate the additional value of EEG-fMRI method in the presurgical evaluation of focal intractable epilepsy. To consider a patient for surgery, the main difficulty is to define accurately the epileptogenic zone. This definition is complex and is often supported by several types of exploration (MRI, FDG PET, neuropsychological testing, video-EEG...). In this study we will evaluate the adding value of the simultaneous recording of EEG and fMRI in the epileptogenic zone definition.
