Abstract

Accumulating evidence supports a causal role of hypertension for cognitive decline above and beyond its relationship to frank stroke. Hypertension-associated pathologic changes in the brain and its vasculature include vascular remodeling, impaired cerebral autoregulation, cerebral microbleeds, white matter lesions, unrecognized lacunar infarcts, and Alzheimer-like changes such as amyloid angiopathy and cerebral atrophy. White matter lesions and retinal vascular changes, both of which can be imaged noninvasively, may reveal the general condition of the cerebral vasculature or the presence of arteriosclerotic or hypertensive encephalopathy. These noninvasive indicators may also identify a subgroup in whom infarct prevention, particularly via blood pressure reduction, is of paramount importance. Optimal control of blood pressure on a population-wide basis, but particularly in those prone to cognitive loss, is thus a critically important but as yet elusive goal that should be fully exploited for its potential to reduce future cognitive impairment.

In this review, the authors conclude that antihypertensive treatment has been shown to reverse the increased risk of cerebrovascular morbidity and mortality associated with hypertension, and also to decrease the risk of cognitive impairment and dementia. The mechanisms by which various classes of antihypertensive drugs prevent cognitive decline and their relative benefits remain unclear.PubMedCrossRefGoogle Scholar

Correction of these remodeling changes is seen in response to antihypertensive therapies that cause vasodilation (angiotensinconverting enzyme inhibitors), but not with those that decrease cardiac output (β-blockers).Google Scholar

Results from the Austrian Stroke Prevention Study, a 3-year cohort study of 273 participants (mean age, 60 years), are summarized, including the finding that only baseline diastolic blood pressure and the presence of early confluent or confluent white matter hyperintensities at baseline predicted progression of white matter hyperintensities over 3 years. Genetic association analyses suggest that genes involved in oxidative defense and in the renin-angiotensin system may be involved in the etiology of white matter lesions.PubMedCrossRefGoogle Scholar
