脑电图、经颅多普勒在血管性痴呆诊断的应用分析

THE APPLIED ANALYSIS OF EEG AND TCD IN DIGNOSIS OF VASCULAR DEMENTIA

目的:探讨脑电图和TCD在血管性痴呆(VD)早期诊断中的应用价值。方法:对38例VD患者进行脑电图、TCD检测,并进行结果分析。结果:36例脑电图异常表现为:a节律变慢,广泛e活动,局限性慢波(出现在额区、颞区、顶区),2例出现痫样放电;TCD表现血流速增快或减慢,频谱形态改变,为高阻型,动脉硬化表现;结论:脑电图、TCD检测是诊断VD的重要方法,尤其在发病早期。

Objective: To explore the applied value of EEG and TCD in early dignosis of vascular dementia. Motheds:EEG and TCD were determined in 38 patients with vascular dementia. The results were analyzed. Results; The main manifestations in 36 abnormal EEG included slow a rhythm, suffusing θ activities and focal slow waves (frontal lobe, temporal lobe, parietal lobe) ; abnormal TCD: cerebral blood flow was increased or decreased, abnormal spectral frequency ( higher force ) , showed arteriosclerosis Conclusion: The EEG and TCD dectection might be the very important methods for diagnosis of VD.
