This study aims to understand how to best encourage diverse community members to join the Alzheimer's Prevention Trial (APT) Webstudy, a registry designed to speed up clinical trials for Alzheimer's disease. Researchers are testing if offering a $25 gift card (Financial Incentive) is more effective at encouraging enrollment than a small non-monetary gift (Nominal value gift), like a reusable grocery bag. You can join if you are 50 or older, can read English or Spanish, and have email access. You cannot join if you have a current dementia diagnosis. The main goal is to see how many people enroll in the APT Webstudy on the first day. This study is currently recruiting 400 participants.
