Physical activity and white matter lesion progression: assessment using MRI.
We evaluated the association between physical activity and changes in white matter lesions (WMLs) on MRI in a sample of 179 older adults comprising 59 incident cases of Alzheimer disease, 60 persons with mild cognitive impairment, and 60 persons who remained cognitively stable over a median 5-year follow-up. Physical activity was not significantly associated with a decreased rate of periventricular or deep WML progression.
