Quantitative EEG in progressing <i>vs</i> stable mild cognitive impairment (MCI): results of a 1‐year follow‐up study

Abstract

qEEG revealed decreased alpha activity in progressing MCI and mild AD prior to an increase of slow wave activity, which typically occurs in advancing AD. This finding may reflect an affection of thalamo-cortical relay activity and cortical connectivity in the early disease course of AD. Reduced alpha activity in MCI subjects at baseline may have prognostic value regarding future cognitive decline.
