目的探讨脑卒中后癫痫的临床特点及发病机理。方法对525例脑卒中病例中35例癫痫发作的临床资料进行回顾性分析。结果本组脑卒中后癫痫的发生率为6.66%,多为单纯性部分性发作(占71.4%)。结论脑卒中后继发性癫痫与脑卒中部位有明显关系,脑缺血缺氧是早发癫痫的重要致病因素,胶质斑痕的形成易导致迟发性癫痫。
Objective To investigate the clinical features and pathogenesis of post-stroke epilepsy. Methods The clinical data of 35 seizures in 525 stroke patients were retrospectively analyzed. Results The incidence of post-stroke epilepsy in this group was 6.66%, mostly simple partial seizures (71.4%). Conclusions Post-stroke secondary epilepsy has a significant relationship with the location of stroke. Cerebral ischemia and hypoxia are the important risk factors of premature epilepsy. The formation of glial scar leads to delayed epilepsy.
