Higher physical activity is associated with greater myelin content in older adults with cerebral small vessel disease and mild cognitive impairment

Myelin loss is considered a marked feature of cerebral small vessel disease (cSVD). Although physical activity levels may exert protective effects over cSVD pathological changes, its specific relationship with myelin content in this population is unknown. Therefore, we investigated whether physical activity levels are associated with myelin content in community‐dwelling older adults with cSVD and mild cognitive impairment.
