【 摘 要 】

As a leading risk factor for stroke, hypertension is also an important risk factor for cognitive impairment. Midlife hypertension doubles the risk of dementia later in life and accelerates the progression of dementia, but the correlation between late-life blood pressure and cognitive impairment is still unclear. Beside blood pressure, the effect of pulse pressure, blood pressure variability and circadian rhythm of blood pressure on cognition is currently attracting more and more attention. Hypertension induces alterations in cerebrovascular structure and functions, which lead to brain lesions including cerebral atrophy, stroke, lacunar infarcts, diffuse white matter damage, microinfarct and microhemorrhage, resuling in cognitive impairment. Hypertension also impairs the metabolism and transfer of amyloid-β protein (Aβ), thus accelerates cognitive impairment. Individualized therapy, focusing on characteristics of hypertensive patients, may be a good choice for prevention and treatment of cognitive impairment.
