Greater mental stimulation ‘can prevent brain degeneration in later life’

People who live mentally stimulating lifestyles are less likely to experience mental degeneration in later life, according to new research.

The study, led by the University of Exeter alongside collaborators from Bangor, Newcastle and Cambridge, indicated that stimulating the brain by taking on leadership roles at work or remaining in education can be instrumental in helping people stay mentally healthy.

Data from more than 2,000 mentally fit people over the age of 65 was examined for this research, showing that these kinds of activities can help people to maintain a higher level of "cognitive reserve".

A healthy diet, more physical activity, more social and mentally stimulating activity and moderate alcohol consumption all seemed to help improve this cognitive buffer, which means that signs of decline only become evident at a higher threshold of illness or decay.

Professor Bob Woods of Bangor University, said: "Our results highlight the importance of policies and measures that encourage older people to make changes in their diet, exercise more and engage in more socially-oriented and mentally stimulating activities."
