Managing your blood pressure can help reduce your risk of dementia, according to Australian and international researchers. The team combined the results of 17 studies on potential links between dementia, blood pressure and blood pressure medication. They say overall, untreated high blood pressure was associated with a higher risk of dementia than treated high blood pressure. Those who treated their high blood pressure had no greater risk of dementia than those with healthy blood pressure, they add.
