What Is This Study About?
CORT108297 is an FDA-approved drug used to manage the neural and hormonal responses to stress. This study will test whether the drug can improve memory and thinking in people who have mild cognitive impairment (MCI) due to Alzheimer's or who are at risk for developing Alzheimer's due to family history, genetics, or memory problems. Participants will be randomly assigned to take three tablets of either the study drug or a placebo, every day for two weeks. Over 10 weeks, each group will alternate between receiving the study drug or placebo, attend six study visits, and complete cognition and memory tests. After doing a brief, stressful activity, such as public speaking or mental arithmetic, participants will provide saliva samples to measure stress hormone response.
