The Apathy Evaluation Scale: A Comparison of Subject, Informant, and Clinician Report in Cognitively Normal Elderly and Mild Cognitive Impairment

Abstract

In a sample of CN elderly and elderly with MCI, apathy increased over time, particularly in men and those with MCI. AES-S scores may be more sensitive than AES-I and AES-C scores in CN elderly, but less reliable if subjects have MCI. Moreover, the AES-C sub-scale predicted progression from MCI to AD dementia.
