Lower blood pressure slashes the risk of Alzheimer’s by 15%, study finds.
Lowering blood pressure could prevent Alzheimer’s disease, according to new research.
A study of more than 9,000 over 50s found those who got it below the newly recommended level – with a top reading under 120 – slashed their risk of memory problems by about a fifth.
They were also a sixth (15 percent) less likely to develop dementia, a figure that may be conservative to the short duration of the trial.
Dr Maria Carrillo, chief science officer at the Alzheimer’s Association, said: ‘Proof that lowering blood pressure can lower risk for dementia may be key to improving the lives of millions of people around the world.’
Participants who reduced their blood pressure to a top reading of 120 – instead of 140 – were 19 percent less likely to develop mild cognitive impairment (MCI), a condition that often leads to dementia.
They also had fewer signs of damage on brain scans, and there were fewer cases of dementia.
