Summary

The goal is to build a large database to speed up research into brain diseases like Alzheimer's and Parkinson's.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could speed up research into treatments for Alzheimer's and other brain diseases by providing a large pool of willing participants.
- What could go wrong
- This is an observational registry, not a treatment trial. It relies on self-reported data, which may not be as accurate as in-person assessments.
