The IDEAL Study: Information About Alzheimer's Disease for Latinos in New York City

Columbia University·interventional·Posted Jul 15, 2020·Updated Nov 17, 2025

In Brief

A clinical study evaluating Disclosure of APOE genotype for Alzheimer Disease. Completed, enrolled 374 participants across 1 site.

Detailed Summary

This study will assess the psychosocial and behavioral impacts of receiving Alzheimer's disease genetic risk assessment incorporating APOE genotypes among Latinos in northern Manhattan. The investigators will conduct a longitudinal, community-based study with a mixed methods design. Participants will be randomized to learn about their lifetime risk of late-onset Alzheimer's disease (AD) based either on (a) Latino ethnicity and family history alone (genotype nondisclosure group), or (b) the same factors plus APOE genotype (genotype disclosure group). Responses will be evaluated at 6 weeks, 9 months, and 15 months after risk assessment. In the quantitative component of the study, the investigators will assess psychosocial outcomes, memory test performance, and health-related behaviors. In the qualitative component of the study, the investigators will investigate the lived experience of receiving personal AD risk information, using a stress and coping theoretical framework.
