While the link between several mid-life cardiovascular risk factors and dementia was similar for both sexes, for blood pressure it was not- find George Institute researchers -in a study of just over half a million people. The study showed that both low and high blood pressure were associated with a greater risk of dementia in men, but for women, the risk of dementia increased as blood pressure went up. Lead author Jessica Gong said that while more research was needed to verify these findings, they may point to better ways of managing risk. “Our results suggest a more tailored approach to treating high blood pressure could be more effective at preventing future cases of dementia,” she said. Dementia is fast becoming a global epidemic, currently affecting an estimated 50 million people worldwide. This is projected to triple by 2050 – mainly driven by aging populations. Rates of dementia and associated deaths are both known to be higher in women than men. In 2016, it overtook heart disease as the leading cause of death in Australian women and it is the second leading cause of death for all Australians. In the absence of significant treatment breakthroughs, the focus has been on reducing the risk of developing the disease and cardiovascular risk factors are increasingly recognised as contributors to different types of dementia. To examine sex differences in major cardiovascular risk factors for dementia, George Institute researchers used the UK Biobank, a large-scale biomedical database that recruited 502,489 Britons aged 40-69 years (free from dementia at study initiation) between 2006 and 2010.
