Alzheimer's Prevention Trials (APT) Webstudy


The Alzheimer’s Prevention Trials (APT) Webstudy is an online registry designed to accelerate enrollment into Alzheimer's clinical trials by identifying and tracking individuals who may be at higher risk for developing the disease.

After signing up, participants will fill out a brief assessment of their cognitive abilities and complete a 20-minute test to assess their memory and thinking skills. The test will be repeated quarterly, and participants will have access to their scores.

By tracking changes over time, researchers will identify those individuals who may be at higher risk for developing Alzheimer's disease. Participants may be invited for in-person testing at a clinical site across the United States. In-person testing will involve either a brain scan or a lumbar puncture, also known as a spinal tap, to look for beta-amyloid, a protein that accumulates abnormally in the brains of people with Alzheimer's disease. If those tests indicate higher risk, the participant may then be notified of clinical trials that he or she would be eligible for.

Participants can take part in the program without volunteering for clinical trials. The online test data will be aggregated for research purposes.
