Effectiveness of antihypertensive drugs to prevent cognitive decline, mild cognitive impairment, and dementia. An overview of systematic reviews

Review question / Objective: To determine effectiveness of antihypertensive drugs to prevent different dementia subtypes such as Alzheimer’s disease and vascular dementia. Condition being studied: Dementia is a global health burden, with the number of affected individuals increasing. A recent meta-analysis reported that the prevalence of all-type dementia was 697 per 10,000 people and the prevalence of Alzheimer’s disease was 324 per 10,000 people. The SHEP and SYST-EUR were the two first randomized controlled trials to show that hypertension treatment reduces dementia risk.
