RECRUITING

A Mechanistic Trial of the Neurobiology of Extinction Learning and Intraparietal Sulcus Stimulation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This study will be the first of its kind to explore the impact of continuous theta burst stimulation (cTBS) to the intraparietal sulcus (IPS) on arousal symptoms among patients with posttraumatic stress disorder (PTSD). The investigators will demonstrate that IPS cTBS results in significant reduction in arousal (measured by startle response) compared to sham cTBS, that IPS cTBS interacts with extinction training to further improve arousal, and that there is a dose/response effect of cTBS on arousal. The investigators will also demonstrate that IPS cTBS significantly improves retention of extinction learning, the experimental analogue of exposure therapy.
