Abstract:
From 1957-92, 3235 patients with chronic drug-resistant epilepsy were admitted and examined as candidates for surgery, in 639 classical resective intervention, removal of epileptic foci, was performed. In 101 patients other functional or disconnection surgery was performed. Based on this experience some problems and difficulties of bioelectrical investigation and localization of epileptic foci by scalp EEG recording are presented.
