Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This study is testing a treatment called transcranial direct current stimulation (tDCS) — a safe, non-invasive technique that gently stimulates areas of the brain involved in attention and focus. Children receive this stimulation while doing exercises designed to improve concentration and thinking skills. The researchers want to see if this approach can reduce inattention, impulsivity, and hyperactivity in children with ADHD.
Many children with ADHD benefit from medication, but about 30% either don't respond well to stimulant medications, experience unwanted side effects, or their families prefer not to use medication. This trial explores whether the treatment could be a helpful option for these children.

If you join this study, you will receive several sessions of brain stimulation (tDCS) while practicing cognitive exercises designed to strengthen attention and focus. Half of the participants will receive active stimulation, and half will receive a placebo (sham) stimulation that feels the same but does not deliver the actual treatment — this helps researchers know whether the real treatment works. You will have visits to the research center and be asked questions about your attention, behavior, and daily functioning before, during, and after the treatment to see how much it helps.
