ADHD Clinical Trial - A Trial of Two-Week Brain Stimulation for Teenagers

Status Recruiting

Clinical Trial 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.

Clinical Trial Description

Working memory (WM) is the foundational cognitive control process of holding information 'in mind' to execute goal-directed behaviors. WM deficits are an established component of all primary childhood psychiatric disorders, most notably ADHD. Despite being one of the strongest predictors of poor clinical and functional outcomes in pediatric mental health, there remains a dearth of available treatments for WM deficits. Non-invasive brain stimulation holds tremendous promise in transforming psychiatry, as it takes a "brain-first" approach to treatment. The dorsolateral prefrontal cortex (DLPFC) is the known structural foundation of WM, and the interaction between slow and fast brain waves (i.e., "theta-gamma coupling [TGC]") is a neural, functional foundation of WM. Thus, the DLPFC and TGC are potential brain-based targets for the modulation of WM with brain stimulation. Intermittent theta burst stimulation (iTBS) is a novel paradigm that applies a three-minute dose of stimulation to the DLPFC at an intensity that directly mimics TGC dynamics. The objective of this study is to utilize the experimental therapeutics approach to investigate whether iTBS can lead to a lasting modulation of WM-related neural oscillations. In a crossover, double-blind design, a sample of adolescents (13-17 years old) with ADHD and WM deficits will complete a two-week course of active iTBS and a two-week course of sham iTBS to their left DLPFC. The central hypothesis is that iTBS at the left DLPFC will modulate TGC and subsequently improve attentional/WM abilities in adolescent WM deficits. Aim 1 will examine the effect of iTBS on TGC and attention/WM (i.e., target engagement). Aim 2 will examine the relationship between change in TGC and attention/WM performance and symptoms (i.e., target validation). The exploratory aim will identify the neocortical circuitry underlying oscillatory modulation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
