EEG Biomarkers for ADHD Stimulant Treatment

12 giugno 2026 aggiornato da: Anne Arnett, Boston Children's Hospital

EEG Biomarkers for Pediatric ADHD Treatment Stratification

Pediatric attention deficit hyperactivity disorder (ADHD) affects up to 10% of children in the U.S. and more than 90% are prescribed stimulant medications according to clinical guidelines. The standard of care for pharmacological treatment of ADHD is a "trial-and-error" approach that requires frequent dose adjustments, side effects management, and communication among doctors, parents, and school personnel over weeks, months, and years. In the first year following prescription of stimulant medications, >50% of doctors are not able to conduct the recommended follow-up with their patients. Many patients stop taking medications or keep taking medications that do not work well, as a result.

This investigation will use a non-invasive brain imaging technique called EEG to look for activity in the brain that can predict which children with ADHD will respond well to two commonly prescribed stimulant medication groups, methylphenidate and amphetamines. Based on a previous study, it is expected that EEG signals can differentiate among children whose ADHD symptoms will get better on methylphenidate, and those whose ADHD symptoms will get better on amphetamines.

220 participants ages 7-11 with ADHD will be enrolled. Participants will not have autism or intellectual disabiltiy. They will not currently be taking psychiatric medications. Participants will not have not taken stimulant medications before or have tried stimulant medications >6 months or experienced an improvement in their ADHD symptoms by taking a stimulant medication before.

Study Participation Includes:

  1. Participant and caregiver complete a 3-hour visit at the Arnett Laboratory at 2 Brookline Place. During this visit, participants complete a brief IQ test and an EEG while their caregiver completes questionnaires and a clinical interview. The caregiver will give permission to request survey responses from the participant's teacher.
  2. The next day, the participant and caregiver will come back to the laboratory for a 1-hour visit. The participant will do another EEG while the caregiver fills out more surveys. The doctor will take the participant's vital signs and prescribe the medication.
  3. The participant will be randomly assigned to take either methylphenidate HCl or amphetamines every morning for 3 weeks. At the end of each week, the caregiver and teacher will fill out a questionnaire about the participant's behaviors and symptoms, including side effects.
  4. For one week, the participant will not take medications. They will come back into the lab for another EEG at the end of that week.
  5. The participant will then take the other medication every morning for 3 weeks. At the end of each week, the caregiver and teacher will fill out a questionnaire about the participant's behaviors and symptoms, including side effects.
  6. It will take participants about 7 weeks to complete this study. During this time, they will complete 3 in-person and 6 virtual study visits.
  7. The research funds will cover cost associated with the study. The participant's health insurer will not be billed for the medications or treatment. Medications will be provided through the research pharmacy.
  8. Participants will be given a report at the end of the study with details about the medication trials, symptom response, and any other findings. They will receive up to $270 for the completion of the study. Some travel-related costs will be covered by the study.

Descrizione dettagliata

Pediatric attention deficit hyperactivity disorder (ADHD) affects up to 10% of children in the U.S. and more than 90% are prescribed stimulant medications according to clinical guidelines. The standard of care for pharmacological treatment of ADHD is a "trial-and-error" approach that requires frequent titration, side effects management, and communication among providers, parents, and school personnel over weeks, months, and years. This level of effort often exceeds the capacity of primary care providers, who manage treatment for the majority of affected children. In the first year following stimulant prescription, recommended routine follow-up occurs in <50% of cases treated in primary care. Consequently, suboptimal dosing and early discontinuation of stimulants are exceedingly common, with >75% pediatric ADHD patients showing suboptimal medication adherence in the first year.

The current proposal will utilize electroencephalography (EEG), a non-invasive, affordable brain measurement tool, to characterize predictive biomarkers for response to two commonly prescribed stimulant medication classes: methylphenidate (MPH) and amphetamines (AMP). Predictive biomarkers can be used to guide clinical decision making and treatment selection for pediatric ADHD, ultimately shortening the time from diagnosis to treatment optimization; reducing burden on clinicians, families, and teachers; and leading to better lifetime outcomes for children with ADHD. Thus far, behavioral- and genomic-based treatment biomarkers have not been successful for ADHD, and there is increasing demand by patients and providers to identify a solution.

Building on our pilot data, this study will constitute a prospective, single-blind, double-baseline randomized MPH-AMP crossover trial with 220 treatment-naïve, 7-11-year-old children with ADHD. EEG will be collected prior to each medication arm, and treatment response will be determined using 3-week rapid titration protocols, consistent with our pilot study and other published trials. Trained clinicians will characterize each participant as a "responder" or "non-responder" for each medication.

EEG features with small to medium effect sizes that are predictive of positive response to MPH and AMP will be identified. Preliminary data suggest MPH and AMP will have distinct EEG predictive biomarkers. To further examine the translational potential of these results, test-retest reliability and classification agreement of biomarkers over 24 hours and 4 weeks will be estimated. Results of this study have potential to accelerate pediatric mental health treatment development and precision medicine care for ADHD.

Lasso di tempo
Medication A Clinical Global Impressions - Improvement Scale (CGI-I)
Lasso di tempo: Week 3 Virtual Visit (Day 22)
Clinician rating of participant ADHD symptom improvement on medication A. The Clinical Global Impressions - Improvement Scale (CGI-I) is rated by a trained study clinician on a scale of 1-7, with scores of 1 ("very much improved") and 2 ("much improved") corresponding to clinically significant symptom improvement. Scores of 3-7 will indicate no improvement or worsening of symptoms.
Week 3 Virtual Visit (Day 22)
Medication B Clinical Global Impressions - Improvement Scale (CGI-I)
Lasso di tempo: End of Study Virtual Visit (Day 50)
Clinician rating of participant ADHD symptom improvement on medication B. The Clinical Global Impressions - Improvement Scale (CGI-I) is rated by a trained study clinician on a scale of 1-7, with scores of 1 ("very much improved") and 2 ("much improved") corresponding to clinically significant symptom improvement. Scores of 3-7 will indicate no improvement or worsening of symptoms.
End of Study Virtual Visit (Day 50)
Frontal Theta Beta Ratio
Lasso di tempo: Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
Theta-Beta Ratio (TBR): TBR will be calculated from periodic resting EEG. Periodic power isolates the oscillatory component of the EEG by subtracting the aperiodic power spectra from the total power. Periodic power is extracted with the Fitting Oscillations and One-Over-f (FOOOF) MATLAB toolbox which parametrizes resting state EEG data into aperiodic and periodic components. Resting spectral power values will be averaged over theta (4-6 Hz) and beta (13-30 Hz) frequencies across midline electrode clusters (frontal: Fz, F3, F4; central: Cz, C3, C4; parietal: Pz, P3, P4; occipital: Oz, O1, O2). Our primary analyses will focus on frontal TBR during the Lights-Off Resting condition.
Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
Aperiodic Dynamics
Lasso di tempo: Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
Aperiodic Dynamics: The aperiodic exponent for lights-off and lights-on resting conditions will be averaged across midline electrode clusters FOOOF MATLAB toolbox. Aperiodic dynamic values will be computed for each participant as the difference between lights-on and lights-off exponent, divided by the lights-off resting exponent, as in prior publications. Thus, higher scores will indicate greater exponents in the lights-on experiment. Primary analyses will use the central electrode cluster.
Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
P100 Visual Evoked Potential Amplitude
Lasso di tempo: Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
VEP P100 Amplitudes. The P100 VEP component will be derived from a passive pattern-reversal visual evoked potential (VEP) task that includes 200 500ms trials of a black and white checkerboard reversal over 3 minutes. P100 amplitudes will be averaged over an occipital electrode cluster (Oz, O1, O2) from approximately 75-150ms and extracted for each trial. Primary analyses will focus on mean VEP amplitude over trials.
Eligibility Visit (Day 0), Baseline Visit (Day 1), Crossover Visit (Day 29)
Vanderbilt Rating Scales
Lasso di tempo: Baseline, Medication A Week 1, Medication A Week 2, Medication A Week 3, Crossover Week 4, Medication B Week 5, Medication B Week 6, End of Study Week 7
The Vanderbilt Rating Scales include 18 items corresonding to DSM-5 ADHD symptoms. Parents and teachers will each complete the scales using an electronic form. Items are rated on a scale of 0-3, with 0 = symptom never or rarely occurs, and 3 = symptom often or almost always occurs. Total symptom severity is calculated as the sum of all 18 items; inattention symptom severity is calculated as the sum of items 1-9; hyperactivity/impulsivity symptom severity is calculated as the sum of items 10-18.
