FMRI will be performed at Ben Taub General Hospital on 20 adolescents with ADHD during an attentional response inhibition task while participants are medication-free and medicated with methylphenidate. We will also utilize DISC-4, Hyperactivity Index of the Conners Parent and Teacher Rating Scales, and IQ testing. Participants will also undergo an extensive neuropsychological assessment. If a subject is found to have TD during the open label phase, they will continue in the study without contributing to the primary objective. Subjects may be terminated from the study if at any time they are not responding favorably to treatment.
