Study Summary

This will be an open label study using daily does of up to 126mg/day of Concerta in the treatment of children and adolescents, ages 12-17, who meet DSM-IV criteria for ADHD. Specific hypotheses are as follows: Hypothesis 1: Children and adolescents with ADHD will have significantly higher ACC and DLPFC Glutamate/myo-Inositol containing compounds (Glu/Ino) and Glutamate/creatine + phosphocreatine (Glu/Cr) than matched HCS. Hypothesis 2: After six weeks of treatment, OROS methylphenidate will lower ACC and DLPFC Glu/Ino and Glu/Cr levels in children with ADHD who are methylphenidate responders.

Primary Outcome

Comparison of treated ADHD participants (6 weeks on Concerta) and Healthy Control Subjects (HCS) This measure is a ratio of Glutamate (excitatory neurotransmitter) to myo-inositol (cyclic sugar alcohol) containing compounds in the anterior cingulate.

Interventions
