Do people become more apathetic as they grow older? A longitudinal study in healthy individuals

Abstract

ABSTRACTBackground: The aim of this study was to determine levels, rates and progression of apathy in healthy older persons and to investigate factors associated with its progression.Methods: Seventy-six healthy elderly subjects, aged 58–85 years (mean 69.9), who were recruited by general advertisement and through local community groups, participated as a control group for a longitudinal study of stroke patients. Data were collected on demographic, psychological, neuropsychological and neuroimaging (MRI) variables and apathy was rated by informants on the Apathy Evaluation Scale (AES).Results: Apathy scores and rates increased over 5 years, especially in men. Change of apathy was associated with informant ratings of cognitive decline in the years prior to baseline assessment but not to subsequent neuropsychological, neuroimaging or functional changes.Conclusions: Apathy increases with age in otherwise healthy community-dwelling individuals, particularly in men.
