Description:Purpose
To examine in persons with varying degrees of cognitive impairment the relationship between self-reports of cognitive complaints and quality of life (QOL).
Method
Older adults (n=259) with normal cognition, Mild Cognitive Impairment (MCI), and mild stage Alzheimer’s disease (AD) dementia completed tests of cognition and self-report questionnaires about QOL and three kinds of cognitive complaints: cognitive difficulties, distress from cognitive difficulties, and believing you had more memory problems than most people. Bivariate, multivariable, and multivariate regression analyses assessed relationships between domains of QOL and each cognitive complaint.
Results
Bivariate and multivariable analyses controlling for severity of cognitive and functional impairment found that cognitive complaints were related to relatively lower quality of daily life (QOL-AD, DEM-QOL), greater depression (GDS), more anxiety (BAI), higher perceived stress (PSS), and lower general mental wellbeing (SF-12 MCS).
Discussion
Cognitive complaints have robust associations with QOL. These findings have implications for AD prevention trials and management of clinical populations.
