Physical Function, Life Expectancy, and Cognitive Impairment in Older Adults: A 12-Year Longitudinal Cohort Study

Preventing dementia is crucial due to its current and projected global prevalence. Older adults with cognitive impairment/dementia have worse physical function than healthy individuals. However, it is important to quantify the association between performance-based physical function and life expectancy. This study aimed to assess how performance-based physical function affects life expectancy in older adults with and without mild cognitive impairment and dementia.
