Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Age 12-18 years
  • English fluency of participant and parent and able to provide informed consent/assent
  • Clinical diagnosis of ADHD and confirmation of diagnostic criteria on the Diagnostic Interview for Anxiety, Mood, and OCD and Related Neuropsychiatric Disorders, Child and Adolescent Version (DIAMOND-KID)

  • IQ > 70

Who cannot join

  • Participants will be screened to exclude individuals with neurological or medical conditions that might confound the results, as well as to exclude participants in whom MRI or TMS might result in increased risk of side effects or complications. Common contraindications include metallic hardware in the body, cardiac pacemaker, patients with an implanted medication pumps or an intracardiac line, or prescription of medications known to lower seizure threshold. These account for most of the exclusion criteria listed below:
  • Intracranial pathology from a known genetic disorder (e.g., NF1, tuberous sclerosis) or from acquired neurologic disease (e.g. stroke, tumor), cerebral palsy, history of severe head injury, or significant dysmorphology
  • History of fainting spells of unknown or undetermined etiology that might constitute seizures
  • History of seizures, diagnosis of epilepsy, or immediate (1st degree relative) family history epilepsy
  • Any progressive (e.g., neurodegenerative) neurological disorder
  • Chronic (particularly) uncontrolled medical conditions that may cause a medical emergency in case of a provoked seizure (cardiac malformation, cardiac dysrhythmia, asthma, etc.)

  • Contraindicated metal implants in the head, brain or spinal cord (excluding dental implants or fillings)
  • Non-removable makeup or piercings
  • Pacemaker, implanted medication pump, or ventriculo-peritoneal shunt
  • Vagal nerve stimulator, deep brain stimulator, or transcutaneous electrical nerve stimulation unit
  • Signs of increased intracranial pressure
  • Intracranial lesion
  • History of head injury resulting in prolonged loss of consciousness
  • Substance abuse or dependence within past six months (i.e., DSM-5 substance use disorder criteria)
  • Chronic treatment with prescription medications that decrease cortical seizure threshold, not including psychostimulant medication if deemed to be medically safe as part of the medical review process.
  • Active psychosis or mania
  • Acute suicidal intent
  • Current pregnancy
  • Significant visual, hearing or speech impairment
  • Dental braces
  • Current wards of the state

About this study

The objective of this project is to examine the differential therapeutic effect of intermittent theta burst stimulation (iTBS; a type of repetitive transcranial magnetic stimulation) to the left DLPFC versus right PreSMA in modulating working memory (WM) versus inhibitory control (IC) deficits. Fifty adolescents (12-18 years old) with parent-reported WM and IC deficits and diagnosed ADHD will be randomized to DLPFC or PreSMA targeted 3x-daily iTBS for a total of ten days (30 total sessions).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • intermittent theta burst stimulation (iTBS)Device

    Device: Stimulation will be delivered using a Nexstim NBT System 2 device. Motor Threshold: The iTBS pulse intensity will be set at 80% of resting motor threshold (MT). The iTBS protocol will administer 2-second trains with an 8-second inter-burst interval for 1800 pulses [600 bursts]), in 50 Hz bursts at 5 Hz (i.e., 200 ms intervals). Each session will last approximately nine minutes. As three sessions will be administered per day, there will be a 20-30 minutes break between each of the nine-minute iTBS sessions. Magnetic pulses will be delivered in an MRI neuro-navigated manner using a cooled figure-eight coil. The PreSMA target will be approximately defined based on MNI coordinates: 13, 18, 62. The left DLPFC target will be approximately defined based on MNI coordinates: -44, 28, 16.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. EEG, source-localized oscillatory beta band bursting during SST/SWMT

    PreSMA-targeted iTBS will lead to greater relative activation of the IC network versus the WM network (and the opposite pattern for DLPFC-targeted iTBS).

    Measured: Visit 13, approximately 1-2 days after iTBS

  2. fMRI-measured blood oxygenation level-dependent (BOLD) activity during SST/NBT

    PreSMA-targeted iTBS will lead to greater relative activation of the IC network versus the WM network (and the opposite pattern for DLPFC-targeted iTBS).

    Measured: Visit 13, approximately 1-2 days after iTBS

  3. Task-based WM/IC performance on SWMT/N-Back/SST

    PreSMA-targeted iTBS will lead to greater relative improvement of IC versus WM (and the opposite pattern for DLPFC-targeted iTBS)

    Measured: Visit 13, approximately 1-2 days after iTBS

  4. Rater-Based WM/IC symptoms (BRIEF-2)

    PreSMA-targeted iTBS will lead to greater relative improvement of IC versus WM (and the opposite pattern for DLPFC-targeted iTBS)

    Measured: Visit 13, approximately 1-2 days after iTBS

Questions about this trial

What is this clinical trial studying?

A study testing intermittent theta burst stimulation (iTBS) in people with ADHD, run by Bradley Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 22 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Brian K Kavanaugh, PsyD; PI, PsyD ABPP (4014321359, bkavanaugh@brownhealth.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

EEG, source-localized oscillatory beta band bursting during SST/SWMT (time frame: Visit 13, approximately 1-2 days after iTBS). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2025.
