Study Details

Study Description

Brief Summary

The purpose of this study is to test the effects of non-invasive neuromodulation, transcranial magnetic stimulation on brain function in individuals with obsessive-compulsive disorder (OCD). This study is focused on the mechanism(s) by which brain stimulation might change the functioning of regions implicated in OCD, and thereby inform possible future therapeutic uses.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Transcranial Magnetic Stimulation

Transcranial Magnetic Stimulation applied over the pre-supplementary motor area (pSMA), for ten sessions, Monday through Friday, over the course of two weeks.

Device: Transcranial Magentic Stimulation
This is a form of mild brain stimulation delivered noninvasively. The device delivers pulses of magnetic energy through a coil placed on the scalp. The treatment takes 41 seconds, and takes place for ten sessions, Monday through Friday, over the course of two weeks
Other Names:
  • Continuous Theta Burst Stimulation (cTBS)
  • Outcome Measures

    Primary Outcome Measures

    1. Change in activation of pre-supplementary motor area/dorsal anterior cingulate cortex (pSMA/dACC) on functional magnetic resonance imaging (fMRI) during the Multi-Source Interference task (MSIT) [Baseline and 6 months]

    Secondary Outcome Measures

    1. Change in Yale-Brown Obsessive Compulsive Scale (Y-BOCS) [Baseline and 6 months]

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    18 Years to 70 Years
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    Yes
    Inclusion Criteria:
    • Current primary OCD diagnosis and current Y-BOCS total score of ≥16

    • 18-70 years of age

    • Ability to speak, read, write, and understand English sufficiently well to complete study procedures and provide informed consent

    • No use of psychiatric medications or stable psychiatric medication use for a minimum of 6 week prior to study entry

    • Ongoing psychotherapy allowed if already established for three months or more before study entry

    Exclusion Criteria:
    • History of primary psychotic disorder or bipolar disorder

    • Present acute suicidality

    • History of head injury, epilepsy, or other clinically significant neurological illness except tic disorders
