The researchers found that people who had higher levels of cognitive reserve remained mentally fit for a longer time. This also made them less prone to illnesses such as dementia.
According to PTI, Linda Clare, Professor at the University of Exeter said, "Losing mental ability is not inevitable in later life. We know that we can all take action to increase our chances of maintaining our own mental health, through healthy living and engaging in stimulating activities."
She said that it is vital to understand how and why this happens so that people could be given meaningful and effective measures to take control of their lives and live an active lifestyle even in old age. She said that people who engage themselves in stimulating activity which challenges their brain into adopting different strategies have a higher cognitive reserve. This causes the creation of a buffer in their brain which makes them more resilient toward mental illnesses caused by age.
The research team analyzed if a healthy lifestyle was what led to better performance on a mental ability test and found that a healthy diet, more physical activity, more social and mentally stimulating activity and moderate alcohol consumption all were responsible in boosting cognitive performance.
"We found that people with a healthier lifestyle had better scores on tests of mental ability, and this was partly accounted for by their level of cognitive reserve," said Professor Bob Woods of Bangor University in the UK.
