Outcome Measures

Primary Outcomes (1)

  • rTMS reduces substance use

    Opioid use as measured by quantitative urine toxicology via high pressure liquid chromatography at screening, baseline, enrollment (3 times per week for 3 weeks), and follow-up phases (weekly for 4 weeks).

    1 - 7 weeks

Secondary Outcomes (1)

  • rTMS applied to the DLPFC provides neuromodulatory effects

    1 - 7 weeks

Other Outcomes (1)

  • Functional connectivity changes

    week 1, week 3, and week 7

Study Arms (1)

Study Group

EXPERIMENTAL

Participants will receive a type of TMS called repetitive TMS (rTMS) wherein the magnetic pulses delivered will be close together in a rapid sequence. They will receive excitatory rTMS with a stimulation frequency of 10 Hz or higher.

Device: Repetitive Transcranial Magnetic Stimulation (rTMS)

Interventions

During the rTMS session, an electromagnetic coil is placed against the subjects scalp. The electromagnet painlessly delivers a magnetic pulse that stimulates nerve cells in the region of the brain involved in memory and thinking.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Able to provide written informed consent, and to comply with study procedures.
  • Be actively enrolled in the COAT Program
  • Meet DSM-V criteria for a primary OUD assessed via structured clinical interview
  • Columbia-Suicide Severity Rating Scale score \< 4
  • Be abstinent from opioids (other than prescribed buprenorphine/naloxone) and illicit substances other than marijuana at the time of the enrollment, confirmed via urine drug screen
  • Willing to practice contraception to avoid pregnancy the duration of the study

You may not qualify if:

  • Medical conditions that preclude rTMS: including vasodepressor syncope, glaucoma, increased intracranial pressure, cardiac disease, migraine disorder, cerebral vascular events (cerebral vascular accident, transient ischemic attack), any brain lesions (such multiple sclerosis), brain injury, seizure disorder (or family history) of any type, and have cardiac pacemakers or implanted medication pumps
  • DSM-V criteria for major psychiatric illness other than depression
  • Major Cognitive Disorder (as evidenced by a score of \<21/30 on the Mini Mental Status Exam (MMSE)
  • Pregnancy
  • Positive responses to the TMS Adult Safety Screen or the MRI checklist
  • Intracranial metallic objects (excluding dental fillings)
  • Uncorrected visual acuity problems
  • Mobility limitations
  • Clinically significant EKG abnormalities (including QTc interval prolongation \>450 ms in men or \>480 ms in women)
  • Unwillingness to abstain from prescribed drugs
  • Prior rTMS treatment
  • Other mental or physical conditions that, in the PI's opinion, would be inappropriate for study participation.
  • Intake of one or a combination of the following drugs forms a 'Strong Potential Hazard' for application of rTMS due to their significant seizure threshold lowering potential:
  • Imipramine, Amitriptyline, Doxepine, Nortriptyline, Maprotiline, Chlorpromazine, Clozapine, Foscarnet, Ganciclovir, Ritonavir, Amphetamines, Cocaine (MDMA, ecstasy), Phencyclidine (PCP, angel's dust), Ketamine, Gamma-hydroxybutyrate (GHB), Alcohol, Theophylline.
  • Recent withdrawal from one of the following drugs forms a 'Strong Relative Hazard' for application of rTMS due to the resulting significant seizure threshold lowering potential:
