Brain connectivity moderating the association cognitive intraindividual variability and mobility in the cognitively frail older adults

Abstract

Background: Cognitive frailty is the concurrent presence of mild cognitive impairment (MCI) and physical frailty, causing one to be at greater risk for cognitive decline. Cognitive intraindividual variability (IIV) is a critical component of cognition involved in the maintenance of higher‐order processes under load.
