Does aerobic activity improve cerebral vasculature in healthy aged subjects?
Aerobic activity is associated with improved cerebral vasculature metrics on MRA, suggesting a potential mechanism for healthy brain aging.
Aerobic activity in elderly subjects is associated with lower vessel tortuosity values and an increase in the number of small-caliber vessels. It is possible that an aerobic exercise program may contribute to healthy brain aging. MRA offers a noninvasive approach to visualizing the cerebral vasculature and may prove useful in future longitudinal investigations.
