Benefits of Controlling Blood Pressure

Controlled blood pressure is advantageous to our overall health and longevity. In addition to providing benefits to our cardiovascular system, optimal blood pressure management also improves cerebrovascular health – which may lower the risk of dementia, stroke, and other diseases of the brain. In fact, many prospective cohort studies have shown a link between lower blood pressure and better cognitive health, which includes a reduced risk of Alzheimer’s-type dementia. To further examine the relationship between blood pressure and this type of dementia, the National Academies of Science, Engineering, and Medicine (NASEM) investigated a sysLower Blood Pressure and Alzheimer's Risktemic review of several randomized controlled trials by the Agency for Healthcare Research and Quality.

Study Design & Results

Although NASEM found that most of the four randomized controlled trials they looked at yielded inconsistent results on whether controlled blood pressure that was sustained exerted a reduced risk of Alzheimer’s-type dementia, one trial had positive results. The Systolic Hypertension in Europe trial (Syst-Eur) showed that, compared to placebo, treatment of isolated systolic hypertension in those sixty years or older lowered the occurrence of dementia by fifty percent (Marshall, 2017).

NASEM, however, pointed out that studies which were not randomized controlled trials demonstrated a stronger, more consistent relationship between regulated blood pressure and a reduced risk for Alzheimer’s-type dementia. It has been suggested that randomized controlled trials on this subject may be impractical for reaching a firm conclusion, so more trials employing different methods may help researchers determine the strength of this link (Marshall, 2017).
