Abstract

In 288 men and women from general population in a cross-sectional survey, all neuropsychological tests were negatively associated with age; memory and executive function were also positively related with education. The hypertensives HT were less efficient than the normotensives NT in the test of memory with interference at 10 sec MI-10 −33%, , clock drawing test CLOX −28%, , and mini-mental state examination MMSE −6%, . Lower MMSE, MI-10, and CLOX were predicted by higher systolic odds ratio, OR, 0.97, ; OR 0.98, ; OR 0.95, and higher pulse blood pressure BP OR 0.97, ; OR 0.97, ; and 0.95, . The cognitive reserve index CRI was 6% lower in the HT and was predicted by higher pulse BP OR 0.82, . The BP vectors of lower MMSE, MI-10, and CLOX were directed towards higher values of systolic and diastolic BP, that of low CRI towards higher systolic and lower diastolic. The label of hypertension and higher values of systolic or pulse BP are associated to worse memory and executive functions. Higher diastolic BP, although insufficient to impair cognition, strengthens this association. CRI is predicted by higher systolic BP associated to lower diastolic BP.
