Blood pressure belongs on your brain-health checklist

When people think “brain health,” blood pressure rarely tops the list. It should. This is not just association: the SPRINT MIND randomized trial found that targeting systolic pressure under 120 mm Hg (versus the usual under 140) cut the risk of mild cognitive impairment by about 19%. That is controlled trial evidence, the strongest kind we have for a dementia lever.

Most people do not know where they stand: Stage 1 hypertension starts at 130/80, and high blood pressure is usually symptomless. The mechanism is intuitive: chronic high pressure damages the small vessels the brain runs on. For carriers, who already carry elevated brain and vascular risk, that makes blood pressure a high-leverage, quietly powerful target.

The good news is it is measurable and treatable, through exercise (worth about 4 to 5 mm Hg on its own), diet and less sodium, weight, alcohol moderation, sleep (including ruling out apnea), and medication when needed.
