Blood Pressure & the Brain.
Does keeping a lid on your blood pressure help keep your brain sharp as you age?
Researchers randomly assigned 9,361 people aged 50 or older with hypertension to take drugs to lower their systolic blood pressure to one of two targets: less than 140 (standard treatment) or less than 120 (intensive treatment). But after three years, the trial was cut short when it became clear that the intensive group had a lower risk of strokes, heart attacks, and death.
After the three-year trial and three years of follow-up, there was no difference in "probable dementia" (the primary outcome), although the trial may have been too short to see one. However, the intensive-treatment group had a 19 percent lower risk of mild cognitive impairment than the standard group.
What to do Aim for a blood pressure of 120 to lower your risk of a heart attack or stroke ... and, possibly, to protect your memory and thinking ability.
