Your chances of Alzheimer’s disease vary based on where you live. Why is that?

A research team led by the University of Michigan School of Public Health will combine and standardize memory and thinking test data from older adults in 20 countries to better understand why dementia risk differs around the world. The harmonized data is needed to better understand why some countries have higher rates than others and will allow the researchers to make fair, apples-to-apples comparisons.
