Cerebral white matter lesions in essential hypertension.
The pathogenesis and clinical significance of cerebral white matter lesions (WML) remain controversial. Most studies have shown that age, hypertension, diabetes mellitus, and a history of stroke or heart disease are the most important factors related to the presence of cerebral WML. Moreover, some studies suggest that the presence of WML are closely related to cerebrovascular disease and cognitive impairment in elderly patients with vascular risk factors, particularly hypertension. In this review, different points of view about cerebral WML are discussed, with special focus on the presence of WML in essential hypertension. Some authors suggest that the presence of WML in hypertensive patients could be considered an early marker of brain damage.
