[Delayed epileptic seizures in adults].

A retrospective study of 464 patients with delayed epilepsy was carried out. There were 311 males and 153 females with their ages ranging between 20 and 87 years. The seizures were Generalized in 298, and Partial in 139. Neurological examination showed abnormalities in 189, and normal finding in 275. The EEG studies and CT scans revealed abnormalities in 196 (80.6%) and 283 (61%) respectively. The CT scan findings were compatible with cerebrovascular diseases in 16.4%, with brain tumors in 12.9%, with craniocerebral trauma in 8.4%, and with diffuse brain atrophy in 7.4%. The CT scans would show a higher frequency of abnormalities if there were local neurological signs with the EEG findings suggesting, partial seizures and focal lesions of the brain. It was considered that a CT scan would be mandatory in the evaluation of patients with delayed epilepsy, even though the EEG and clinical examination were normal.
