Alzheimer's risk info: does knowing help or hurt latinos?
NCT ID NCT04471779
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how giving people information about their genetic risk for Alzheimer's disease affects them emotionally and behaviorally. It involved 374 Latino adults aged 40-64 in New York City who did not have Alzheimer's. Some participants learned their risk based only on ethnicity and family history, while others also got results from a genetic test (APOE). Researchers then tracked their distress, memory, and health habits over 15 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Disclosure of APOE genotype (genetic risk information)
- What this could lead to
- If successful, this could help doctors understand the best way to share Alzheimer's risk information with Latino communities, potentially reducing distress and promoting healthy behaviors.
- What could go wrong
- This is a completed observational study, not a treatment trial. It does not test a drug or cure, so it cannot directly lead to a new therapy. The results may not apply to other ethnic groups.

Not a phased trial
Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.
