Expatriates with worldwide health insurance may wish to consider making lifestyle alterations in order to reduce their risk of developing dementia.
Professor June Andrews, director of the Dementia Services Development Centre at the University of Stirling, said even people with Alzheimer's disease can keep the illness "at bay" through healthy habits.
Socialising, keeping busy, a good diet and regular exercise can reduce the chances of a person suffering from this illness, she added.
Furthermore, keeping to a healthy weight and not smoking are good for the circulatory system and "doctors say what's good for your heart is good for your head", the expert asserted.
Maintaining this kind of lifestyle would also lessen a person's risk of developing diabetes or similar problems, Professor Andrews concluded.
This follows research undertaken by Deborah Barnes PhD and published by the University of California, San Francisco, which found more than 50 per cent of all cases of Alzheimer's disease might have been averted through changes to a person's way of life or treatment of medical conditions.
