Abstract

OBJECTIVE: In light of the increased longevity of people living with HIV infection (PLWH) undergoing antiretroviral therapy (ART), the present study aimed to determine the effects of mood disturbances alongside cognitive and motor symptoms on activities of daily living (ADLs) and quality of life (QOL) in older PLWH in comparison to an aging control sample without notable medical history (CTL) and individuals with Parkinson's disease (PD).METHOD: Forty-one PLWH, 41 individuals with PD, and 37 CTL, aged 45-79 years, underwent neuropsychological, psychological, and neurological assessment including depressive and anxiety symptoms, physical (ADL-p) and instrumental (ADL-i) daily activities, Unified Parkinson's Disease Rating Scale motor ADLs (ADL-UPDRS-II), QOL, and cognitive and motor functions. Hierarchical regression analyses assessed the relative contribution of predictors including demographics, disease-related factors, comorbid conditions, and mood-related factors for ADL and QOL scales.RESULTS: PLWH and PD participants reported more depressive symptoms and higher anxiety and worse QOL and ADL-i than CTL. The PD group had greater ADL-p and motor-related ADL-UPDRS-II difficulties than PLWH and CTL groups. In PLWH, medical comorbidities and alcohol use disorder (AUD)/substance use disorder (SUD) histories significantly contributed to poor physical and motor ADLs. Mood scores, particularly depressive symptoms, were independent predictors of poor QOL and most ADLs in both clinical groups, above the contribution of cognitive compromise.CONCLUSIONS: Mood symptoms contribute significantly to poor ADLs and QOL in people aging with chronic diseases such as long-term HIV infection and PD. Comprehensive assessment and treatment of mood symptoms are recommended for ensuring optimal functional independence and life quality. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
