RECRUITING

Neuromodulation of the Fear Extinction Circuit Using Temporally and Anatomically Specific TMS in Humans

Conditions

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 aims to explore the mechanisms of how transcranial magnetic stimulation (TMS) impacts fear circuits. The overarching objectives are to understand how varying TMS parameters affect targeted brain regions in order to optimize its impact on enhancing fear extinction memory consolidation in a population with known fear extinction deficiencies: post-traumatic stress disorder (PTSD). 250 subjects will take part in this research study across UTHealth Houston. The study will include preliminary screenings, baseline visits, and experimental visits across four days

Inclusion CriteriaExclusion Criteria
  1. * Willing and able to provide informed consent.
  2. * Inclusion Criteria for PTSD Subjects - Diagnosis of current PTSD
  3. *
  1. * Lifetime history of seizure or significant head trauma or other significant neurologic disease (e.g., tic disorder)
  2. * History of serious/significant psychiatric diagnoses ("Axis I" diagnoses)
  3. * Current significant suicidal ideation, plan or intent or suicidal behavior in past 6 months based on CSSRS and clinical judgment or Self-injurious behavior that involves suicidal intent, requires medical attention, or occurs daily
