Staying married for life lowers the risk of dementia, according to a new study. Spouses who get married and stay married - without any breaks - are less likely to develop dementia than anyone else.
Conversely, divorced and single people had the highest rate of dementia. Having children also reduces dementia risk - unmarried people were 60 percent less likely to develop the disease if they had kids.
Results led Norwegian University of Science and Technology researchers to suggest dementia is not an inevitable consequence of ageing, and that society could adapt to prevent the disease.
