The Alzheimer's Prevention Registry (www.endALZnow.org) will collect contact and demographic information on individuals. The objective is to provide information the latest news and advances in Alzheimer's prevention research, and to inform enrollees about research studies in their community. Enrolled individuals will receive regular email communications. As research studies become available, individuals will be notified via email with information as to how proceed should they be interested. Registry enrollees are under no obligation to participate in a research study. Study opportunities may include surveys, healthy lifestyle interventions (e.g., diet, exercise), memory & thinking tests, brain scans, and investigational drug trials.
