Physical and Psychological Function Jointly Determine Cognitive Impairment and Life Expectancy in Older Adults

I am highly interested in the recent article titled “Physical Function, Life Expectancy, and Cognitive Impairment in Older Adults: A 12-Year Longitudinal Cohort Study” by Gallardo-Gómez et al.1 The authors provided compelling evidence that older adults preserving good physical function may enjoy approximately 3 additional years of life free from any cognitive impairment, and that individuals with mild cognitive impairment but not dementia who maintain good physical function may live more years. These findings carry profound implications for clinical practice and healthy aging management.
