New research suggests that a more positive outlook on ageing could help reduce the risk of Alzheimer's disease. The study, carried out by the Yale School of Public Health and published in the journal Psychology And Aging, is the first to link these brain changes to a culturally based psychosocial risk factor.
To examine a possible link between dementia and negative beliefs on ageing, the team of researchers looked at the brain MRI scans of healthy, dementia-free subjects from the Baltimore Longitudinal Study of Aging, the US's longest-running scientific study of ageing.
