Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Forty children with and 40 children without Attention deficit Hyperactivity Disorder (ADHD) receive Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) or placebo via a dietary intervention. Cognitive control functions are measured with functional Magnetic Resonance Imaging (MRI) before and after the intervention. Behavioural change is monitored with behavioural scales.
