This study investigates the relationship between frailty status and white matter integrity (WMI) in older adults, focusing on associations with frailty status.
We aimed to compare the incidence of motoric cognitive risk syndrome (MCR)—a pre-dementia syndrome that is identified by a combination of slowed gait speed and cognitive complaints—and previous mild parkinsonian signs (MPS) in older adults without Parkinson disease who do not have dementia.
