Cerebrovascular and cognitive impairment are less well studied. Therefore, this study analyzed changes in cognitive function in patients with different stages of hypertension compared to nonhypertensive controls. Methods and Results-In a cross-sectional study, 221 (71 normotensive and 150 hypertensive) patients were compared. Patients with hypertension were divided into 2 stages according to blood pressure (BP) levels or medication use (HTN-1: BP, 140-159/90-99 or use of 1 or 2 antihypertensive drugs; HTN-2: BP, >= 160/100 or use of >= 3 drugs). Three groups were comparatively analyzed: normotension, HTN stage 1, and HTN stage 2. The Mini-Mental State Examination, Montreal Cognitive Assessment, and a validated comprehensive battery of neuropsychological tests that assessed 6 main cognitive domains were used to determine cognitive function. Compared to the normotension and HTN stage-1, the severe HTN group had worse cognitive performance based on MiniMental State Examination (26.8 +/- 2.1 vs 27.4 +/- 2.1 vs 28.0 +/- 2.0; P= 0.004) or Montreal Cognitive Assessment (23.4 +/- 3.7 vs 24.9 +/- 2.8 vs 25.5 +/- 3.2; P< 0.001). On the neuropsychological tests, patients with hypertension had worse performance in language, processing speed, visuospatial abilities, and memory. Age, hypertension stage, and educational level were the best predictors of cognitive impairment in patients with hypertension in different cognitive domains. Conclusions-Cognitive impairment was more frequent in patients with hypertension, and this was related to hypertension severity.engopenAccesscognitioncognitive impairmenthigh blood pressurehypertensionmini-mental-stateischemic vascular dementiablood-pressure levelsalzheimers-diseaseverbal fluencyprevalenceeducationpopulationintelligencevalidationarticleCopyright WILEY-BLACKWELL10.1161/JAHA.116.004579Cardiac & Cardiovascular Systems
