Official title
Developing a Mechanistic Neurobiological Model of Exposure Therapy Response Based on Fear Extinction Theory
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Social anxiety disorder affects as many as 12% of Americans, resulting in significant distress and disability. Although exposure therapy is one of the best treatments available, as many as 25% of patients do not respond and we do not know why. Extinction learning is thought to be the mechanism of exposure therapy, and the neuroscience of extinction learning has advanced significantly since exposure therapy was developed; however, there has been little application towards improved clinical outcomes. This project aims to improve exposure therapy response for patients with social anxiety disorder by directly linking exposure therapy response to the neurobiology of extinction learning. It also aims to increase our scientific understanding of how brain circuits work to support extinction learning. To do this, 80 adults with social anxiety disorder will randomly be assigned to either receive exposure therapy right away, or to wait before therapy. Participants will all complete a functional magnetic resonance imaging scan to assess extinction learning before the therapy.
