Risk Disclosure Impact for Alzheimer's Disease

No Placebo GroupAll trial participants will receive the active study treatment (no placebo)

Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What makes this Alzheimer's disease treatment unique?

This treatment is unique because it focuses on disclosing genetic and biomarker information to assess Alzheimer's disease risk, which is not commonly done in standard treatments. It aims to help individuals understand their risk and make informed decisions, despite the challenges and controversies surrounding the predictive value and psychological impact of such information.12345

What is the purpose of this trial?

This trial provides participants with a report predicting their future risk of developing Alzheimer’s disease. It targets people without memory or thinking problems in an aging study. The prediction is made using genetic data, brain scans, blood tests, and demographic information.

Findings from Research

Disclosing Alzheimer's disease risk has traditionally been discouraged due to the limited predictive value of tests and concerns about psychological harm, but interest in risk information is growing, especially with the rise of direct-to-consumer genetic tests.
Research indicates that individuals seeking Alzheimer's risk information through formal education and counseling generally find it beneficial and do not report negative effects, suggesting a potential shift in how risk information could be communicated.
