Abstract

Conventional electroencephalographic (EEG) frequency bands and peak frequency were investigated in patients with probable dementia of the Alzheimer type (DAT). Measures of EEG topography and activity were also related to the severity of dementia, as assessed by neuropsychological tests. EEG activity measured in conventional frequency bands proved to be the most sensitive parameter for the quantitative differentiation of DAT, whereas the topography of peak frequency was the better qualitative discriminator between healthy subjects and DAT patients.

摘要

对可能患有阿尔茨海默型痴呆（DAT）的患者进行了常规脑电图（EEG）频段和峰值频率的研究。脑电图地形图和活动测量结果也与痴呆严重程度相关，痴呆严重程度通过神经心理学测试进行评估。结果表明，常规频段测量的脑电图活动是DAT定量鉴别最敏感的参数，而峰值频率的地形图是健康受试者和DAT患者之间更好的定性鉴别指标。
