Abstract
As life expectancy grows, brain health is increasingly seen as central to what we mean by successful aging-and vascular brain health as central to overall brain health. Cerebrovascular pathologies are highly prevalent independent contributors to age-related cognitive impairment and at least partly modifiable with available treatments. The current Focused Update addresses vascular brain health from multiple angles, ranging from pathophysiologic mechanisms and neuroimaging features to epidemiologic risk factors, social determinants, and candidate treatments. Here we highlight some of the shared themes that cut across these distinct perspectives: (1) the lifetime course of vascular brain injury pathogenesis and progression; (2) the scientific and ethical imperative to extend vascular brain health research in non-White and non-affluent populations; (3) the need for improved tools to study the cerebral small vessels themselves; (4) the potential role for brain recovery mechanisms in determining vascular brain health and resilience; and (5) the cross-pathway mechanisms by which vascular and neurodegenerative processes may interact. The diverse perspectives featured in this Focused Update offer a sense of the multidisciplinary approaches and collaborations that will be required to launch our populations towards improved brain health and successful aging.
