The link between high blood pressure and dementia has been known for some time. Two recent research reports reinforce this existing knowledge.
One study set out to determine the effects of intensively lowering systolic blood pressure to less than 120 mm Hg on the heart, kidney, and brain in hypertensive older adults who did not have diabetes or stroke; the present report deals with a sub-study focused on brain health, and showed that aggressive treatment of hypertension to less than 120 mm Hg systolic blood pressure is not harmful to the brain, but beneficial.
The second study examined how blood pressure changes/patterns related to dementia risk over time. It was shown that the patterns consisting of midlife and late-life hypertension, and midlife hypertension and late-life hypotension, significantly increased risk of subsequent dementia as compared with people with normal blood pressure.
Here are three media articles about the reports:

Inspired by these reports, here is an article about lowering blood pressure:
