This observational study, called the Alzheimer Prevention Trials (APT) Webstudy, aims to find people who might be at a higher risk for developing Alzheimer's disease. There are no specific interventions (like drugs) being tested. The goal is to enroll people into other Alzheimer's prevention research studies over five years. You can join if you are between 50 and 85 years old, do not have dementia, and are willing to do cognitive tests online and possibly have biomarker assessments (tests that look for signs of disease in your body). The study is looking to enroll 200,000 people. The current recruitment status is unclear.
