AP) — The University of Kansas Medical Center is planning a $3 million project to study the role of exercise in preventing Alzheimer’s disease.

The study will be funded by the National Institutes of Health. The medical center is looking for 100 healthy people 65 or older to participate in the trial.

Participants who are at a higher risk for Alzheimer’s disease will walk on a treadmill regularly for one year. They will then undergo brain scans to determine if the exercise is reducing the risk of getting Alzheimer’s.
