Cognitive Vulnerability to Stress in Individuals at Risk for Alzheimer's Disease

Recruiting now · Not applicable

Conditions studied: Mild Cognitive Impairment, Alzheimer Disease

In brief

The goal of this clinical trial is to learn about how genetics and the response to stress predicts cognitive decline in individuals with mild cognitive impairment. The main question\[s\] it aims to answer are: * Does the hormone response to acute stress predict the degree of cognitive impairment following acute stress? * Do genes associated with the risk for Alzheimer's disease influence the relationship between stress hormone response to stress and cognitive impairment following stress? * Do cognitive impairment following acute stress and genes associated with the risk for Alzheimer's disease predict cognitive decline and change in biomarkers for Alzheimer's disease 2 years later? Participants will have 3 in-person study visits. The first 2 will occur at baseline and the 3rd visit will occur 2 years later. During the visits, participants will provide blood and saliva samples, undergo a 10-minute social stress procedure, complete questionnaires, and take tests of memory and other thinking skills. Someone who knows the participant (a "study partner") will be asked questions about the participant's daily functioning at the first and 3rd study visits.
