Association between apathy and satisfaction with meaningful activities in older adults with mild cognitive impairment: Apopulation-based cross-sectional study.

Abstract

This cross-sectional study aimed to clarify the relationship between apathy, meaningful activities, and satisfaction with such activities of older adults with mild cognitive impairment (MCI). We analyzed 235 older adults with MCI (≥65 years, mean age: 76.9±6.4 years, women: 63.4%) who participated in a community-based health check survey (Tarumizu Study 2018). MCI was defined as at least 1.5 SD below the reference threshold (age- and education-adjusted score) on one or more of the computerized cognitive test including memory, attention, executive functions, and processing speed. Apathy symptoms were assessed using three of the 15 items of Geriatric Depression Scale. Participants selected meaningful activities from the 95 activities of the Aid for Decision-Making in Occupation Choice and evaluated their satisfaction and performance. Apathy in MCI was prevalent by 23.8%. The categories of meaningful activities revealed no difference, with, or without apathy. Logistic regression analysis showed that activity satisfaction was significantly associated with apathy after adjusting for age, sex, education, instrumental activities of daily living, depressive symptoms, and MCI subtype (OR, 0.62; 95% CI, 0.44-0.88, p=0.008). Satisfaction with the activities that are deemed meaningful is associated with apathy among community-dwelling older adults with MCI.
