| 摘 要： | 利用BEAM分析技术,以50例正常人为对照,用Z值概率差异地形图,对83例部分性与全面性发作的癫痫病人脑电背景活动的δ与θ不对称性情况进行分析,并与其它结果比较后显示,BEAM对癫痫病人的不对称性δ、θ的检出率达72％,较EEG目测分析敏感,其显示的病变区与EEG目测分析、CT、SPECT结果大多符合,可用作痫灶的定侧定位,亦有助于全面性癫痫与部分性癫痫的鉴别。

| Abstract: | Asymmetry of delta and theta activity of epileptic subjects and control subjects were measured by Z score significance probability Mapping (Z-SPM).The ratio of asymmetry of delta and theta activity in 83 patients was 72%.It was more sensitive than routine EEG test.The asymmetical areas of delta and theta often coincided with the lesions in CT scans and rCBF reduced in SPECT.It can be useful in localization of epileptogehic focus and in differential diagnosis between generalized seizure and partial seizure. |
