Alzheimer Prevention Trials (APT) Webstudy
The APT Webstudy is not a treatment trial. It is an online registry that tracks cognitive health over time in people 50 and older who do not have dementia. The goal is to identify individuals who may be at higher risk for Alzheimer's and connect them with future clinical trials. There is no drug or intervention involved — just periodic online cognitive testing and possible referral for biomarker testing.
You may qualify if
- male or female at least 50 years of age
- no evidence of dementia
- willing to participate in remote longitudinal cognitive testing and possible referral for biomarker assessment based on risk
You're excluded if
- N/A. Anyone can register for the APT Webstudy, however, only individuals identified using the risk algorithm will be referred for in-person biomarker assessments.
