About this study

Attention-Deficit/Hyperactivity Disorder (ADHD) is the most commonly diagnosed neurodevelopmental disorder in childhood. Patients with ADHD present inattention, impulsivity and hyperactivity causing severe impairments on academic achievement, social and professional life and daily functioning. Medications are effective in a majority of children with ADHD, but about 30% do not respond or tolerate stimulants, and some parents refuse pharmacological treatments.Transcranial Direct Current Stimulation is a safe and non-invasive technique of brain stimulation used in several neurological and psychiatric disorders, and recently in ADHD. In patients with ADHD, tDCS stimulations targeted frontal regions improve executive and attentional functioning and daily life symptoms. The objective of this project is to evaluate the efficacy of tDCS (vs sham) during cognitive-remediation exercises on ADHD symptoms (inattention, impulsivity and hyperactivity as defined by DSM-5) in children with ADHD between 7 and 14 years of age.

What is being measured

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

  1. Variation of ADHD-RS(ADHD Rating Scale-IV) between both arms

    The ADHD Rating Scale-IV is completed independently by the parent and scored by a clinician. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). If 3 or more items are skipped, the clinician should use extreme caution in interpreting the scale. Results from this rating scale alone should not be used to make a diagnosis.

    How to Score

    For inattention (IA) subscale raw score: Add the odd-numbered items

    For hyperactivity-impulsivity (HI) subscale raw score: Add the even-numbered items

    To obtain the total raw score: Add the IA and Hi subscale raw scores

    Convert the raw scores to percentile scores by using the appropriate scoring profile provided on the back of the rating scale.

    Measured: at 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Transcranial Direct Current Stimulation in people with Attention Deficit Hyperactivity Disorder and Transcranial Direct Current Stimulation, run by Centre Hospitalier Universitaire, Amiens at 1 site in France.

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 0 inclusion and 5 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 29 May 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 France. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Patrick BERQUIN, Pr ((33)3 22 08 76 70, berquin.patrick@chu-amiens.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Variation of ADHD-RS(ADHD Rating Scale-IV) between both arms (time frame: at 4 weeks). 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 29 May 2025.
