ADHD Study for Children 8 to 12 Years Old

Why are we doing this research?

Cincinnati Children's is conducting a research study, sometimes known as a clinical trial or clinical study, to learn more about ADHD. The study involves transcranial magnetic stimulation, or "TMS", a hand-held magnet held over the scalp.

Who can participate?

Children 8 to 12 years who have been diagnosed with ADHD may be eligible to participate.


  • ADD / ADHD

What will happen in the study?

If your child qualifies and you decide you want your child to be in the study, you and your child will come to Cincinnati Children’s three times during approximately one month. These are the things that will happen to your child while in the study:

We will:

  • Collect information from you and your child related to past medical history and medications, development, learning, and current symptoms.
  • Complete diagnostic and psycho-educational testing with your child, as well as tests of patterns of thinking and emotion and tests of motor coordination.
  • Complete a test to look at an area of your child’s brain that controls movement, using a research device called a transcranial magnetic stimulator (TMS). This involves using a hand-held magnet over the scalp. The strength of the magnetic pulses is similar to the strength of pulses used in brain MRI scanners.
  • Administer study medication. At one visit the medication will be 10 mg of methylphenidate. At the other visit it will be placebo. The study is “blinded”, meaning that on the day of the visit neither you nor the research team will know which pill was given. TMS testing is repeated after the dose.

You and your child will be given a consent form that thoroughly explains all of the details of the study. A member of the study staff will review the consent form with you and will be sure that all of your questions are answered.

What are the good things that can happen from this research?

Your child will not have a direct benefit from participating in this study. However, we hope to learn information from the study that may help us with more effective treatments for ADHD in the future.

What are the bad things that can happen from this research?

Possible risks and discomforts will be discussed with those interested in learning more about the study.

Will you/your child be paid to be in this research study?

Families will receive up to $175 for time and effort.
