Condition or Therapy: Attention-deficit hyperactivity disorder (ADHD) and Attention-deficit disorder (ADD)
Category: Psychiatry and Behavioral Medicine

What is the goal of this study?

We want to learn more about how children with attention deficit hyperactivity disorder (ADHD) or attention-deficit disorder (ADD) respond to an FDA-approved medicine called methylphenidate (brand name Concerta). We also want to learn what happens when they stop taking the medicine. We want to understand if stopping the medicine affects their thinking, behavior or how they do in school.

Who can join the study?

This study might be a good fit if your child:

  • Is 7-11 years
  • Has attention problems 
  • Has not taken medicines yet for ADHD or ADD

What happens in the study?

If you choose to take part, your child would take an FDA-approved medicine called methylphenidate (brand name Concerta) to treat the ADHD or ADD.

The study lasts 12 weeks. Your child would take the medicine for 8 weeks. After 8 weeks, children will be assigned to one of two groups. One group will stop taking the medicine. The other group will take the medicine for another 4 weeks.

You and your child would be asked to come in for study visits.
