Older persons who have acquired positive beliefs about old age from their surrounding culture are less likely to develop dementia, a study has found.
The research, published in the journal PLOS ONE, examined whether culture-based age beliefs influence the risk of developing dementia among older people, including those who carry the high-risk gene variant.
"This makes a case for implementing a public health campaign against ageism, which is a source of negative age beliefs," Levy said.
The researchers studied a group of 4,765 people, with an average age of 72 years, who were free of dementia at the start of the study.
The study demonstrated that APOE e4, a high-risk gene variant, carried with positive beliefs about ageing had a 2.7 per cent risk of developing dementia, compared to a 6.1 per cent risk for those with negative beliefs about ageing, over the four-year study duration.
