Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is intended to examine the impact of receiving a genetic risk assessment for Alzheimer's disease (AD) among individuals with Mild Cognitive Impairment (MCI).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Alzheimer's disease is a common condition affecting memory and thinking. Genes can sometimes be used to provide risk estimates for the eventual development of certain common diseases. Apolipoprotein E (APOE) is one gene which can provide information about a person's chances of developing Alzheimer's disease.

Some people with a diagnosis of Mild Cognitive Impairment (MCI) are curious to learn more about the chance of developing Alzheimer's disease. In the REVEAL IV Study, we are examining the psychological and behavioral impact of learning genetic risk information pertaining to the chance for an individual with MCI to progress to dementia of the Alzheimer's type within three years.

Participation in this study requires an initial phone call which will elicit some demographic information about the participant and his or her study partner. A first in-person visit to the research clinic will consist of an education session, the administration of knowledge and attitudinal surveys and some tests to assess memory and thinking skills. This visit will take approximately 2-3 hours. Participants with MCI will have their blood drawn for genetic testing. Participants will then be randomized to one of two groups. Those in the intervention arm will receive a three-year risk estimate for the chance of progressing to dementia of the Alzheimer's type based on age, the diagnosis of MCI and their own APOE gene test result. Those in the comparison arm will receive a three-year risk estimate for the chance of progressing to dementia of the Alzheimer's type based on age and the diagnosis of MCI, without the APOE gene test result. Participants randomized to the comparison arm will have the opportunity to learn their own APOE gene test result at the end of the study. Participants and their study partners will be followed for 6 months following disclosure of results with 1 additional clinic visit and 1 additional phone interviews.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

APOE Genotype Non-Disclosure

Subjects will receive Alzheimer's disease risk disclosure. This assessment is based on age and MCI status alone.

Group Type ACTIVE_COMPARATOR

Alzheimer's disease risk disclosure

Intervention Type BEHAVIORAL

Subjects with MCI will learn a three-year numerical risk estimate for the chance of progressing to dementia of the Alzheimer's type.

APOE Genotype Disclosure

Subjects will receive both APOE genotype and Alzheimer's disease risk disclosure. The assessment is based on age, MCI status, and genotype.

Group Type EXPERIMENTAL

APOE genotype and Alzheimer's disease risk disclosure

Intervention Type BEHAVIORAL

Subjects with MCI will learn their own APOE genotype and a three-year numerical risk estimate for the chance of progressing to dementia of the Alzheimer's type.

Interventions

APOE genotype and Alzheimer's disease risk disclosure

Subjects with MCI will learn their own APOE genotype and a three-year numerical risk estimate for the chance of progressing to dementia of the Alzheimer's type.

Intervention Type BEHAVIORAL

Alzheimer's disease risk disclosure

Subjects with MCI will learn a three-year numerical risk estimate for the chance of progressing to dementia of the Alzheimer's type.

Intervention Type BEHAVIORAL

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
