London, Nov 29: Want to starve off the risk of old-age problems such as memory loss and dementia? Tying a wedding knot may be the right solution, says a study, as interaction of a relationship helps keep the brain active on mode and reduces the risk by a third.
The findings, led by Andrew Sommerlad, Professor at the University College London, revealed that those who married were more than 30 per cent less likely to suffer from the condition than those who remain single, news agency IANS reported.
This is because marriage helps the couple to live a healthier lifestyle, including exercising more, eating a healthy diet, smoking and drinking less, all of which have been associated with the persistence of a reduced risk of such old age problems.
Partners may also have more opportunities for social engagement than single people that further lowers the dementia risk.
Conversely, lifelong singles and widowers were 42 per cent and 20 per cent more likely to develop dementia risk, due to lack of proper interaction, the study said.
However, those who remain unmarried should focus on other areas such as education and proper physical health to cut down the risk of dementia, the researchers asserted.
In the study, published in the journal of Neurology Neurosurgery and Psychiatry, researchers examined over 800,000 people, both married and unmarried.
