目的 :探讨脑梗死继发癫痫的易患因素及用动态脑电图 (AEEG)监测脑电活动。方法 :将 6 5例脑梗死继发癫痫病人 (研究组 )与 6 5例同期住院脑梗死病人 (对照组 )AEEG监测资料进行比较分析。结果 :年龄、性别、基础疾病、神经功能缺损程度不足以推断脑梗死后继发癫痫的易患因素 ;脑梗死发生在脑叶皮质区有癫痫样波的病例较在深部白质区有癫痫样波的病例多 ,两者间比较 ,有显著差异 (P <0 .0 5 ) ;腔隙性脑梗死与脑梗死AEEG检出癫痫样波的病例比较 ,两者间无显著性差异 (P >0 .0 5 ) ;脑梗死继发癫痫单个病灶的病例与多个病灶的病例AEEG检测出癫痫样波比较 ,两者间有极其显著性差异 (P <0 .0 1)。结论 :AEEG监测对脑梗死继发癫痫有重要价值。脑梗死继发癫痫的发生在很大程度上决定于脑梗死的部位和脑组织坏死灶的多少。
Objective: To investigate the predisposing factors of epilepsy secondary to cerebral infarction and to monitor the electroencephalogram (EEG) by dynamic electroencephalogram (AEEG). Methods: AEEG monitoring data of 65 cases of cerebral infarction secondary epilepsy (study group) and 65 cases of in-hospital cerebral infarction (control group) were compared and analyzed. Results: Age, gender, underlying diseases and neurological impairment were not enough to infer the predisposing factors of secondary epilepsy after cerebral infarction. The incidence of cerebral infarction in patients with epileptiform wave in cerebral cortex was higher than that in epileptiform epileptiform wave in deep white matter There were significant differences between the two groups (P <0.05). There was no significant difference in the detection of epileptiform wave between lacunar infarction and AEEG (P> 0.05). There was a significant difference between the two groups (P <0.01). There was a significant difference between the two groups (P <0.01). Conclusion: AEEG monitoring is of great value in the patients with epilepsy secondary to cerebral infarction. Occurrence of cerebral infarction secondary to epilepsy depends largely on the location of cerebral infarction and brain tissue necrosis how much.
