Half of All Alzheimer Cases Might Be Preventable

Newser reports:

At least half of the cases of Alzheimer's disease are linked to common risk factors, and researchers believe the number of cases could be sharply reduced if people took steps to tackle those underlying issues. To reduce the risk of Alzheimer's, researchers say people need to stay active both mentally and physically, quit smoking, and improve their diets, the Globe and Mail reports. The biggest risk factor is having a low level of education, which researchers say is linked to almost a fifth of cases worldwide.
