Summary

This study tests whether offering a $25 gift card encourages older adults from diverse backgrounds to join an Alzheimer's prevention registry. Researchers will recruit 400 people aged 50+ at community events, comparing the gift card to a non-cash gift. The goal is to see if small financial incentives improve enrollment and make research more representative.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
financial incentive ($25 gift card)
What this could lead to
If successful, this could show that small financial rewards help bring more diverse people into Alzheimer's research, making future trials more inclusive.
What could go wrong
This is a small, early-stage study focused on recruitment methods, not a treatment. The results may not apply to other settings or diseases.
