Objective: The aim of the study was to describe the relationship between electroencephalographic (EEG) findings obtained by standardized visual analysis, subclinical white matter lesions (WML) and brain atrophy in a large memory clinic population.& para;& para;Methods: Patients with Alzheimer's disease (AD, n = 58), mild cognitive impairment (MCI, n = 141), subjective cognitive impairment (SCI, n = 194) had clinical, MRI based WML severity and regional atrophy assessments, and routine resting EEG recording. Background activity (BA) and episodic and continuous abnormalities were assessed visually in EEG.& para;& para;Results: WML (p = 0.006) and atrophy in medial temporal regions (MTA) (p = <0.001) were associated with slower BA in all diagnoses. WML were associated in SCI with total episodic EEG abnormalities (p = 0.03).& para;& para;Conclusions: EEG is associated with subclinical WML burden and cortical brain atrophy in a memory clinic population.& para;& para;Significance: Even the standard visually assessed EEG can complement a memory clinic diagnostic workup.
