Trial Information

Summary: Stimulant Drug Treatment of ADHD, Inattentive Type

The purpose of this study is to examine and compare the responses of children with different types of Attention Deficit Hyperactivity Disorder (ADHD) to standard methylphenidate (Ritalin) treatment. Participation involves 5 weeks of treatment: the dose of Ritalin will be gradually increased during the first week of study. The next 4 weeks consist of one week on each of 3 doses of methylphenidate and one week on placebo (a pill without any active ingredients, i.e., without Ritalin) in random order. Random order means that for any of the four weeks, the participant can get Ritalin (either low, medium or high dose) or placebo. The participant does not know the order in which the medication dosage is changed each week. After the completion of the study, the participant is informed of the order of dosages. Participation requires weekly visits to the clinic by the parent(s) and child. Completion of checklists by parents and teacher is required on a weekly basis.
