Contribution of Fast-ripples to the Improvement of the Neurosurgical Management of Drug-refractory Epilepsy

Brief Summary

The main aim of this study is to evaluate the contribution of fast-ripples (FR) information on the neurosurgery management of patients with drug-refractory epilepsy investigated by Stereo-ElectroEncephaloGraphy (SEEG), as measured by freedom from disabling seizures one-year post-surgery. 220 patients (for whom 4-6 usual clinical macro-electrodes will be replaced by hybrid micro-macro electrodes and for whom fast-ripples will be assessed) distributed over 6 centres and 220 control patients(who will undergo an SEEG with the usual electrodes and for whom fast-ripples will not be assessed) distributed over 6 centres. This is a controlled, non-randomized, parallel plan, prospective, multicentre exploratory study.
