Taking beta-blocker drugs may cut the risk of dementia, a trial in 774 men suggests.
The medication is used to treat high blood pressure, a known risk factor for dementia.
In the study, which will be presented at the American Academy of Neurology’s annual meeting in March, men on beta-blockers were less likely to have brain changes suggestive of dementia.
Experts say it is too early to recommend beta-blockers for dementia.
The findings are preliminary and larger studies in men and women from different ethnicities are needed to see what benefit beta-blockers might offer.
People with high blood pressure are advised to see their doctor and get their condition under control to prevent associated complications like heart disease, stroke and vascular dementia.
