多发梗塞性痴呆与多发性脑梗塞脑电地形图的对比研究

BEAM comparison between multi-infarct dementia and cerebral multipal infarcted patiels

本文对29名多发梗塞性痴呆,31名多发性脑梗塞患者及30名正常老年人的脑电地形图做了对比研究,发现多发梗塞性痴呆患者的慢波功率弥漫性增强,目双测不对称;多发性脑梗塞组部分区域的慢波功率增强;两组的 alpha 功率与正常组无差别;两组的 beta 功率较正常组在大部分区域下降。

The brain electro-activity mapping (BEAM) in 29 multi-infarctdementia(MID) and 31 cerebral multipal infarcted patients(CMIP) were studied,with a com-parison of that in 30 normal elderly.MID showed a significant increase in delta and thetapower at all the scalp when compared with normal controls,while CMIP only showed an in-crease in delta and theta power in part area.Both MID and CMIP showed with normal al-pha power and decreased beta power.The authors discuss the potiential differentialdiagnostic clue of BEAM for MID and CMIP in clinic.
