简要总结
The purpose of this study is to examine the brain functioning of OCD patients and healthy controls before and after treatment with Exposure and Response Prevention (EXRP) therapy.
详细描述
The capacity to coordinate thoughts and actions to execute goal-directed behaviors (cognitive control) and the capacity to anticipate, respond to, and learn from reward (reward processing) are key processes for human behavior. Dysfunction in these processes has been hypothesized to contribute to repetitive thoughts and behaviors in many disorders, including obsessive-compulsive disorder (OCD), Tourette Syndrome (TS), and eating disorders. We will use multimodal imaging to investigate neural circuits that support cognitive control and reward processing, using OCD as a model system. The short-term goal is to clarify how circuit-based abnormalities contribute to repetitive thoughts/behaviors; these data will inform future transdiagnostic studies. The long-term goal is to identify control and reward circuit-abnormalities as targets for new transdiagnostic treatments.
