脑卒中患者脑电图与癫痫发作的相关性研究

目的探讨脑卒中患者脑电图EEG和癫痫发作的相关性研究。方法对73例脑卒中后继发癫痫的患者进行EEG监测,癫痫发作时监测皮层EEG,记录异常放电情况。结果经过EEG监测,73例患者EEG的频率均减慢到7-8 Hz,均出现异常放电情况,且多为α波变慢,波率不规则及背景活动不对称,弥散性或局限性及一侧性出现低中等波幅;慢波增多及单侧的痫样放电,多为中度以上异常。最后总结为局限性异常16例,重度异常13例,中度异常36例,轻度异常8例。结论 EEG监测与癫痫的发作具有较高的相关性,所以EEG作为研究脑功能的医学手段,对预测癫痫的发作有着重要价值。

Research of correlation between epilepsy and electroencephalogram of cerebral apoplexy patients

Objective To investigate the correlation between epilepsy and electroencephalogram （EEG） of cerebral apoplexy patients.Methods Electroencephalogram monitoring was applied for 73 cerebral apoplexy patients with secondary epilepsy. During epileptic seizure, cortical EEG was monitored and paradoxical discharge was recorded.Results Through the EEG monitoring, the EEG frequency of the 73 cases all decreased to 7-8 Hz, and they all had paradoxical discharges. Their paradoxical discharges were mainly slow α wave, irregular repetency, asymmetric background activity, and diffuse or circumscribed and unilateral low and moderate amplitude. Increased slow waves and unilateral epileptiform discharges were mainly above moderate abnormality. The results of final summarization were 16 cases with circumscribed abnormity, 13 cases with severe abnormity, 36 cases with moderate abnormity, and 8 cases with slight abnormity.Conclusion There is a high correlation between epilepsy and EEG monitoring. Therefore, as a medical measure for researching brain function, EEG has important value for predicting epilepsy.
