Multimorbidity and Cognitive Decline Over 14 Years in Older Americans

Abstract

Multimorbidity using a validated index weighted to physical functioning was associated with acute decline in cognition and accelerated and persistent cognitive decline over 14 years. This study supports an ongoing geriatric syndrome of coexisting physical and cognitive impairment in adults with multimorbidity. Clinicians should monitor and address both domains in older multimorbid adults.
