Levels of social interaction could explain to the finding, experts have said, after the research showed that people who are single or widowed are more likely to develop the disease.

Experts conducted an analysis of 15 studies which held data on dementia and marital status involving more than 800,000 people from Europe, North and South America, and Asia.

Their study, published in the Journal of Neurology, Neurosurgery, and Psychiatry, concluded that lifelong singletons have a 42% elevated risk of dementia compared with married couples.

Those who have been widowed had a 20% increased risk compared with married people, they found. But no elevated risk was found among divorcees compared with those who were still married.




The researchers, led by experts from University College London, said that previous research has shown that married people may adopt healthier lifestyles.

They may also be more likely to be socially engaged than singletons.

Meanwhile, the effect observed in people who have been widowed could be due to stress that comes with bereavement, they added.

Another explanation could be that developing dementia could be related to other underlying cognitive or personality traits.

Commenting on the study, Dr Laura Phipps of Alzheimer’s Research UK, said: “There is compelling research showing married people generally live longer and enjoy better health, with many different factors likely to be contributing to that link.

The study was published as Alzheimer’s Research UK launched its Christmas campaign calling for more funds for dementia research.

The Santa Forgot campaign, backed by presenter Stephen Fry, aims to raise awareness of the condition as well as funds for studies examining the brain.
