People who take beta blockers to control high blood pressure ... may be at a reduced risk for dementia or alzheimer's disease.
Researchers studied the brains of over 700 deceased elderly men ... most who were being treated for high blood pressure.
Those who had taken beta blockers alone or in combination with other medications had fewer brain abnormalities linked to dementia.
They also had significantly less brain shrinkage than those who had not taken beta blockers.
Men who took beta blockers also had fewer brain lesions called microinfarcts -- which are associated with tiny, undiagnosed strokes.
