目的　研究老年人脑梗塞继发性癫痫的发生率及发作时间 ,发作类型 ,癫痫发作与病变部位的关系、治疗与转归。方法　总结分析 5 6例老年人脑梗塞继发癫痫的临床、CT资料。结果　癫痫病发生率 9 0 % ;分别为早期癫痫与迟发性癫痫 ,而以迟发性癫痫为主 3 9例 (70 9% ) ;发作类型以局限运动为发作为主 3 6例 (64 9% ) ;癫痫发作与病变部位有关 ,病变多位于大脑半球叶 42例 (75 9% ) ,而以额叶为主。结论　老年人脑梗塞继发癫痫发病率高 ,经抗癫痫药物治疗 ,绝大多数能控制 Objective To study the incidence of secondary epilepsy and the onset time, the types of seizures, the relationship between epileptic seizures and the lesion sites, the treatment and prognosis in elderly patients with cerebral infarction. Methods The clinical and CT data of 56 cases of senile cerebral infarction secondary epilepsy were analyzed. Results The incidence of epilepsy was 90%. There were 39 cases of early epilepsy and delayed epilepsy, respectively, and 39 cases of delayed epilepsy (70.9%). The main types of attack were 36 cases (64 9%). Epileptic seizures were related to the lesion site. Lesions were found in 42 cases (75.9%) of the cerebral hemispheres and predominantly in the frontal lobes. Conclusion The incidence of epilepsy secondary to cerebral infarction in the elderly is high, and the majority can be controlled by antiepileptic drugs
