Brief Summary

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.

Eligibility Criteria

* Children, male or females presenting a sufficient compliance for participate aged 7-14 years at the time of Visit 1 (Enrolment/baseline). * Children's parent or legally authorised representative must sign informed consent.

The principal investigator of the center where the child is included signs the document, certifying that the family and the child, or their authorised representative, have received informed consents. * Children meet DSM-5 criteria for ADHD (combined presentation) based on a clinical evaluation using questionnaire ADHD-Rating-Scale (ADHD-RS) and the Kiddie Schedule for Affective Disorders and Schizophrenia French version (Kiddie-SADS). * Subjects have a minimum ADHD-RS total score of 32 at Visit 1. * Children have a minimum CGI of 4 at Visit 1. * Children have an age-appropriate intellectual level evaluated with WISC-5 (Full IQ \>80). * Children in which stimulant medication have been tested previously and stopped for adverse effects could be included in the study after a wash out of at least seven days. Exclusion Criteria: * Children have a neurological pathology or handicap: Epilepsy, cerebral palsy, sequelae of brain injury (traumatic or ischemic or inflammatory...) * Children have a comorbid psychiatric disorder: conduct disorders, autism, severe obsessive-compulsive disorder, mood disorder, bipolar illness, conduct disorder, psychosis, and substance abuse. * Children under medication (stimulant or other psychotropic treatment, benzodiazepine, antidepressant, hypnotics and melatonin) or who did not respond previously to stimulant will not be included. * Severe sleep disorder. * Contraindication to tDCS.
