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.
对464例迟发性癫痫患者进行了回顾性研究。其中男性311例，女性153例，年龄在20至87岁之间。癫痫发作类型为全身性发作的有298例，部分性发作的有139例。神经系统检查显示189例有异常，275例检查结果正常。脑电图研究和CT扫描分别显示196例（80.6%）和283例（61%）有异常。CT扫描结果显示，16.4%与脑血管疾病相符，12.9%与脑肿瘤相符，8.4%与颅脑外伤相符，7.4%与弥漫性脑萎缩相符。如果脑电图结果提示有局部神经系统体征、部分性发作和脑局灶性病变，CT扫描显示异常的频率会更高。研究认为，即使脑电图和临床检查正常，对迟发性癫痫患者进行评估时CT扫描也是必不可少的。
