Are you a man between the ages of 55 to 64? Do you have trouble staying asleep at night? If so, you may be able to take part in a research study to see how sleep affects thinking and brain function. Participation involves two overnight sleep studies, cognitive tests, and two MRI scans. Compensation is provided.
The purpose of this study is to understand how sleep affects thinking and decision making and to find out if deeper sleep improves cognition and brain function. Researchers also want to identify which sleep habits are best for older adults.

WHAT PARTICIPANTS CAN EXPECT
Study participation typically lasts 17 days and includes a phone screening and 3 visits.
The first visit is a baseline screening visit with questionnaires, a clinical interview, and a medical exam with a study physician. Participants will then receive a sleep diary to fill out and an activity monitor to wear on their wrist for the duration of the study.
Eligible participants will be invited to sleep in the lab for two separate overnight sleep studies. During each overnight visit, participants will be asked to perform cognitive tasks and complete a 15 minute MRI scan. Some participants will also be asked to follow a specific sleep schedule each night for one week between each sleep study.
