PURPOSE OF REVIEW: Acute cerebrovascular events once dominated efforts to protect the brain from cardiovascular disease. As stroke prevention and treatment have advanced, attention has broadened to the more continuous vascular processes that contribute to cognitive decline across later life. This review organizes cardiovascular brain injury by route, direct structural injury versus indirect mediated pathways, and tempo, acute events versus chronic processes, with vessel caliber determining lesion topography.
RECENT FINDINGS: Vascular and Alzheimer pathology commonly coexist in older adults with cognitive impairment, and their relationship appears bidirectional but asymmetric: Alzheimer pathology can directly injure the cerebral vasculature, while vascular dysfunction may facilitate Alzheimer pathology and, more clearly, accumulated vascular injury lowers the threshold at which Alzheimer pathology becomes clinically expressed. Covert infarction, microbleeds, white matter disease, and blood-brain barrier disruption accumulate into a cumulative vascular substrate that erodes cognition over decades without requiring a recognized clinical event, and the clinical syndrome follows the lesion, with the subcortical dysexecutive phenotype the modal presentation. Evidence from SPRINT MIND, FINGER, US POINTER, BRAIN-AF, LACI-2, CREST-2, and Mendelian randomization identifies blood pressure control as the best-established intervention, uses discordant and null findings to refine presumed mechanisms, and frames the emerging dilemma of anti-amyloid therapy in patients with substantial vascular disease. In the mixed vascular and Alzheimer disease that dominates late-life dementia, the vascular component is often the more modifiable, and cardiovascular risk management remains among the most actionable strategies for preserving cognition.
