摘　　要：目的：探讨脑卒中继发性癫痫患者脑电图特征。方法对50例脑卒中继发性癫痫患者的脑电图检查结果及其临床资料进行回顾性分析。结果本组患者脑电图均异常，脑电图异常以局限性及广泛伴局限性改变为主，α指数显著下降，δ指数显著升高。本组90．0％的患者病灶位于皮层，66．0％的患者为出血性脑卒中；癫痫发作类型：早发型癫痫占66．0％，迟发型癫痫占34．0％。早发型癫痫以出血性脑卒中为主（75．8％），晚发型癫痫以脑梗死为主（58．9％）。结论脑卒中继发性癫痫患者脑电图均异常，脑卒中后癫痫的发生与脑卒中的位置及类型密切相关。脑电图反映脑功能活动，对皮质缺血十分敏感，有助于判断预后。Objective To explore EEG characteristics of post‐stroke secondary epilepsy （PSSE） patients and EEG diagnostic value .Methods EEG examination results and other clinical data of 50 PSSE patients were retrospectively analyzed .Results EEGs of all patients were abnormal , main EEG abnormalities local and general plus local change ,α index lowered significantly ,and δ height‐ened .Foci of 90 .0% patients were located in cortex ,66 .0% ones were hemorrhagic apoplexy ;seizure types were that early seizure epilepsy made up 66 .0% and late 34 .0% .Early seizure epilepsy was mainly secondary to hemorrhagic apoplexy （75 .8% ） and late to cerebral infarction （58 .9% ） .Conclusion EEGs of all PSSE patients are abnormal ,the PSSE development is closely related to stroke locations and types . EEGs reflex brain function activities ,are very sensitive to cortex ischemia ,and conduce to the judgment of prognosis .
