Objectives To investigate using quantitative EEG the (1) differences between patients with
mild cognitive impairment with Lewy bodies (MCI-LB) and MCI with Alzheimer's disease
(MCI-AD) and (2) its utility as a potential biomarker for early differential diagnosis. Methods
We analyzed eyes-closed, resting-state, high-density EEG data from highly phenotyped
participants (39 MCI-LB, 36 MCI-AD, and 31 healthy controls). EEG measures included
spectral power in different frequency bands (delta, theta, pre-alpha, alpha, and beta) …
