目的　探讨脑梗死与癫痫的相关性及其致痫机制。方法　从 30 2例脑梗死中筛选 2 9例继发性癫痫 ,观察其发作时间及发作类型 ,并与头颅CT及脑电图相对照 ,对癫痫患者进行经典的药物治疗。结果　梗死后癫痫的发作类型及发作时间与头颅CT的脑梗死部位密切相关 ,而与梗死面积无关。结论　脑梗死是继发性癫痫的重要原因之一 ,防治脑梗死也是减少癫痫发病率的重要途径之一。 Objective To investigate the correlation between cerebral infarction and epilepsy and its mechanism of epilepsy. Methods Twenty-nine cases of secondary epilepsy were selected from 30 2 cerebral infarction. The onset time and the type of seizure were observed. Compared with CT and electroencephalogram, classical pharmacotherapy was performed on patients with epilepsy. Results The type of seizure and the time of onset of epilepsy after infarction were closely related to the cerebral infarction site of head CT, but not to the infarct size. Conclusion Cerebral infarction is one of the important causes of secondary epilepsy. Prevention and treatment of cerebral infarction is also one of the important ways to reduce the incidence of epilepsy.
