title: EEG features associated with the occurrence of epilepsy after surgery for intracranial aneurysm and acoustic neuroma.
abstract: An investigation was carried out on 199 postoperative EEGs from 83 patients who underwent surgery for ruptured intracranial aneurysm or acoustic neuroma removal. The tracings were quantified without knowlege of the diagnostic group and whether or not epilepsy had supervened. The number of spikes and sharp components and slow waves at the site of the operative brain lesion were substantially and often significantly greater in the tracings from patients who developed epilepsy than from those who did not.
