Vascular correlates of aging in the brain: Evidence from imaging data

With aging, the brain undergoes a variety of changes with behavioral impacts, including cognitive decline even in healthy aging. In particular, vascular changes in the brain have been shown to be linked to cognition and furthermore influence the widely used neuroimaging measurements that are based on hemodynamics. In this article, we review part of the previous literature on the effects of aging on brain and cognition, and present recent work which helps further our understanding of vascular brain aging.
