Blood pressure ‘link to dementia’
‘Controlling blood pressure from middle-age onwards may dramatically reduce the chances of developing dementia, researchers have said.
Two studies support a link between high blood pressure and dementia risk – with one by an Imperial College London team suggesting treatment could cut this.
This study, by published in the Lancet Neurology journal, found blood pressure drugs reduce dementia by 13%.
The Alzheimer’s Society said better control could save 15,000 lives a year. [..]
The precise reasons why high blood pressure might increase the risk of dementia are not fully understood although many scientists believe that it can starve the brain of bloodflow and the oxygen it carries.’
