目的探讨脑卒中后癫痫发作的临床特点,以及视频脑电图的特征。方法选取我院2013年4月至2014年11月期间接收治疗的70例脑卒中后癫痫患者,所选研究对象按癫痫发作时间分为早发性癫痫组(36例)和迟发性癫痫组(24例),采用回顾的方式进行分析总结。结果 60例患者中早发性癫痫患者为36例(60%),迟发性癫痫患者共24例(40%),两组数据存在一定差异,具有统计学意义(P<0.05)。迟发性癫痫患者脑梗死比较常见,早发性癫痫患者比较常见脑和蛛网膜下腔出血。60例患者中共44例患者脑电图异常,主要表现为癫样放电、局限性慢波活动。结论脑卒中后癫痫发作与病变位置、病程时间、卒中类型有一定关系,脑电图出现异常状况,对患者进行视频脑电图检查对于治疗和预后都有很好的作用。
Objective To investigate the clinical characteristics of seizures after stroke and the characteristics of video EEG. Methods Seventy patients with epilepsy after stroke were selected from our hospital from April 2013 to November 2014. The subjects were divided into premature epilepsy group (36 cases) and delayed epilepsy group (24 cases), using the way of retrospective analysis and summary. Results There were 36 cases (60%) of the 60 patients with early-onset epilepsy and 24 cases (40%) of the patients with delayed-type epilepsy. There was a statistically significant difference between the two groups (P <0.05). Cerebral infarction in patients with delayed epilepsy is more common in patients with early-onset epilepsy brain and subarachnoid hemorrhage is more common. Totally 44 patients in 60 patients had EEG abnormalities, which mainly manifested as epileptiform discharge and localized slow wave activity. Conclusions Post-stroke epileptic seizures have some relations with the location of the lesion, duration of the disease and the type of stroke. The abnormal EEG occurs and the video EEG examination of the patient has a good effect on the treatment and prognosis.
