动态脑电图对缺血性脑卒中后继发癫痫的研究

目的：探讨缺血性脑卒中后继发性癫癎动态脑电图（AEEG）变化、神经功能的缺损情况及临床疗效与预后.方法：将40例缺血性脑卒中后后继发性癫癎患者设为研究组,回顾其AEEG资料,常规脑电图与动态脑电图检查比较;并与对照组40例缺血性脑卒中后无癫癎发作患者进行比较分析.结果：常规脑电图与动态脑电图检查比较：常规脑电图（REEG）检查中度和重度异常16例,占40％;AEEG检查中度和重度异常的比率为35例,占87.5％,AEEG较REEG检查的中、重度异常比率明显增高,具有统计学差异.研究组患者AEEG异常率占95.0％;发生在脑叶皮质区的患者继发癫癎的概率高于发生在皮质下区的患者,两者间AEEG比较差异有统计学意义（P＜0.05）.结论：AEEG可显著提高卒中后癫癎发作患者的脑电异常检出率,其检查结果对预测癫癎发作、病情变化、预后有着重要的价值.

ANALYSIS OF AEEG IN PATIENTS WITH SECONDARY EPILEPSY AFTER CEREBRAL INFARCTION

Objective： To explore the changes of the ambulatory EEG in patients with secondary epilepsy after cerebral infarction, impairment situation of neurological function, clinical curative effect and prognosis. Methods： 40 patients with secondary epilepsy after cerebral infarction were research group, and compared with 40 cases of the control group which had no epilepsy after cerebral infarction in routine EEG and AEEG. Results： The AEEG with abnormal of research group accounted for 95.0%, the change occurs in the brain lobe cortex of patients with secondary epilepsy is higher than that occurs in subcortex location, the two groups have difference statistically. Conclusion： Ambulatory electroencephalogram （ AEEG ） has important value to predict epilepsy happened, changes of the condition and the prognosis.
