Julian Paton: Blood pressure and links to dementia

High blood pressure has become a focus of attention in many quarters. The condition affects one-third of adult New Zealanders and disproportionately more Maori and Pacific people. It's the biggest risk factor for cardiovascular disease - the leading cause of death here and globally - and researchers are now studying its links to dementia in later life. Professor Julian Paton from the University of Auckland's Faculty of Medical and Health Sciences says it's clear we don't yet know everything about controlling high blood pressure, but his research aims to urgently find a new way.
