| Annotation | In a 3-year follow-up of older people living in the community in Azuchi, Japan, cognition was assessed using the Hasegawa Dementia Scale, to examine the cross-sectional association between cognitive impairment and functional disability in each activity of daily living and instrumental activity of daily living (ADL / IADL) item. Cognitive impairment was also examined as a risk factor for incident disability in each ADL-IADL item. Cross-sectionally, severity of cognitive impairment was associated with disability in each ADL-IADL task, with larger effects shown for ADL items. Longitudinally, minimally or mildly cognitively impaired individuals had a significantly higher risk of losing functional abilities compared to those with intact cognition. The population attributable risk (PAR%) indicated that cognitive impairment accounts for 11% to 36% of incident disability in ADL-IADL tasks, with the highest PAR% shown for the ability to feed oneself. Cognitively impaired subjects are heterogeneous; the severity of cognitive impairment has a different impact on incident loss of task-specific ADL-IADL abilities, and comorbidities could affect disabilities differently. Consideration of these heterogeneities will enrich future studies on the impact of cognitive impairment on ADL-IADL abilities. (RH). |
