The purpose of this study is to learn more about body weight and brain function, by comparing cognitive function of people who do and do not undergo bariatric surgery.
Study subjects will visit the clinic at the New York State Psychiatric Institute for an initial evaluation session. During the visit, they will be asked to complete cognitive functioning tests that are done on computer to assess things like memory, attention, and motor skills. Subjects will also be asked to complete questionnaires and answer questions about their backgrounds, medical history, psychiatric history. There are three follow-up visits at 12 weeks, 12 months, and 24 months after the initial visit.
For each session subjects are paid $50, totaling up to $200 for the initial evaluation session and the three follow-up study sessions. Payment in the form of a check will be mailed approximately 4 to 6 weeks after completing a session. (Michael Devlin, M.D.)
