Abstract

Abstract: The complexity characteristics of the electroencephalogram (EEG) of Alzheimer's disease (AD) patients were analyzed and compared with healthy persons of the same age by using nonlinear dynamics theory. The preliminary results showed that the EEG complexity values of AD patients in all leads are clearly lower than the corresponsive values of healthy persons. It indicated that the complexity could be used as a specific parameter for the clinical diagnostic of AD.

Key words: Alzheimer disease(AD), electroencephalogram(EEG), complexity
