“Margaret Daffodil Graham tries to live a healthy life, particularly since she has a health issue that requires constant attention. Like more than 100 million other Americans, the 74-year-old from Winston-Salem, N.C., has high
blood pressure and she has been taking medication to control it since she was in her 30’s. So, when she read that her nearby hospital, Wake Forest Baptist Medical Center, was looking for people with hypertension to volunteer for a study, she quickly signed up, knowing the doctors would monitor her blood pressure more intensively and hopefully lower her risk of developing heart disease and stroke.

What Graham didn’t realize was that by joining the trial, she wouldn’t just be benefiting her heart. The study, called SPRINT MIND, was designed to test whether aggressively lowering blood pressure would have an effect on people’s risk of cognitive decline, including symptoms of dementia related
to Alzheimer’s disease.

Indeed, the trial’s results are now the first solid confirmation that
lowering blood pressure reduces the risk of both mild cognitive impairment (MCI), a degree of brain decline that’s considered the gateway to dementia, and probable dementia. It was a revelation to Graham as well as others who volunteered. “It never occurred to me that controlling my blood pressure could protect me from dementia,” says Arthur Lane, 89, another participant
in the study. “I think this is wonderful.”

Some 150 million people worldwide are expected to be affected by dementia by 2050. And while there are many ways people can change their behavior to lower their risk of heart disease and cancer–such as eating a healthy diet, exercising and avoiding or stopping smoking–there are few similar steps that have been scientifically proven to reduce the risk of degenerative brain disorders like Alzheimer’s.”
