NCT05102864

Brief Summary

The objective of this clinical trial is to examine whether non-invasive brain stimulation can modulate dysfunctional brain dynamics underlying adolescent ADHD to subsequently improve clinical symptoms.

Outcome Measures

Primary Outcomes (3)

  • Change in Theta-Gamma Coupling

    EEG recording will be obtained while the participant completes the Sternberg Spatial Working Memory Test (SWMT). The coupling between theta phase and gamma amplitude will be extracted from the EEG during encoding and maintaining demands.

    Theta-gamma coupling will be obtained before the 1st session, and 24 hours after the 1st, 5th, and 10th sessions. Statistical modeling will examine the CHANGE across these four time points. This change is considered a single primary outcome variable.

  • Change in Parent-Reported ADHD, Working Memory, and Affective-Related Symptoms

    Parents complete the BRIEF-2/Vanderbilt/PROMIS forms

    ADHD/WM/affective symptoms will be obtained before the 1st session, and 24 hours after the 5th, and 10th sessions. Statistical modeling will examine the CHANGE across these time points. This change is considered a single primary outcome variable.

  • Change in Working Memory Test Performance

    Participants complete the Sternberg Spatial Working Memory Test

    SSWMT performance will be obtained before the 1st session, and 24 hours after the 1st, 5th, and 10th sessions. Statistical modeling will examine the CHANGE across these four time points. This change is considered a single primary outcome variable.

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Ability to provide assent and have parent provide parental permission
  • English fluency of the participant and the legal guardian/parent

  • 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, braces or fillings)
  • Non-removable makeup or piercings
  • Pacemaker
  • Implanted medication pump
  • Vagal nerve stimulator

  • TENS unit (unless removed completely for the study)
  • Ventriculo-peritoneal shunt
  • Signs of increased intracranial pressure
  • Intracranial lesion (including incidental finding on MRI)
  • +8 more criteria
