We examined racial differences in cerebrovascular reactivity (CVR) to carbon dioxide and their associations with cognitive function among patients with mild cognitive impairment and hypertension. The results provide evidence for association between impaired CVR and executive dysfunction. Hypertensive African Americans have more compromised cerebral microcirculatory function compared to Caucasians.
