Better diets and nutrition are reducing the risk of dementia and Alzheimer's. The diseases are now less common than they were 20 years ago, new research has found.
Even if medicine never finds a cure, the diseases are becoming less common, and people who develop Alzheimer's are now doing so far later on in life, say researchers at the University of Michigan Medical School.
The reason for the decline in numbers of cases seems to be down to greater awareness of the problem, and better nutrition and diets. Although better eating habits have been adopted in order to reduce heart disease risks, the decline in dementia has been a happy by-product as it shares many of the same risks.
Physical activity, later retirement, longer and later education and maintaining social activities have also played a part in dementia's decline.
