Where you live could shape your dementia risk, massive study finds

A new USC led study of more than 214,000 older adults from 14 countries and regions suggests that preventing dementia may require different strategies in different parts of the world. Researchers found that many of the most important modifiable dementia risk factors, including low education, high blood pressure, and smoking, vary dramatically between countries. The findings indicate that a single global approach to dementia prevention is unlikely to be effective everywhere.
