Participation will provide invaluable insights that could significantly advance this crucial research.
Participation includes:
- Exam and review of personal and family history.
- Cognitive testing.
- Blood or saliva sample.
All visits are provided free of charge and will be repeated every one to two years for three years.
Remote testing is available. Participants will receive a $40 stipend for each visit.
