Children: Attention Deficit Hyperactivity Disorder

Join a Research Study: Attention Deficit Hyperactivity Disorder (ADHD)

Brain Imaging of Childhood Onset Psychiatric Disorders, Endocrine Disorders and Healthy Controls

Magnetic Resonance Imaging (MRI) combines a powerful magnet, radio waves, and sophisticated computer technology to provide exquisitely accurate information about the anatomy and physiology of the living, growing human brain - and it does so without the use of harmful radiation. This allows not only for the scanning of children and teens but of repeated scans over the course of development and has launched a new era of adolescent neuroscience. In this study, researchers will use MRIs to assess brain anatomy and function in healthy volunteers and patients with a variety of childhood onset psychiatric disorders. Identical or non-identical twins are of particular interest for the study. Also, because of questions about differences between boy and girl brains people that have atypical hormone levels, such as in congenital adrenal hyperplasia or precocious puberty, or atypical sex chromosome numbers, such as XXY, XXX, XYY, or XXXXY will be included as well. In addition to the brain images, information will be collected about behavior, emotions, and cognition and combined with genetic testing to explore the relationships between genes, brain, and behavior.

Comparing Attention Deficit Hyperactivity Disorder to Bipolar Disorder in Children: Investigations of Brain Function and Irritability

This research study seeks to learn about how attention deficit hyperactivity disorder (ADHD) and bipolar disorder (BD) are different in children and adolescents. Researchers will describe the moods and behaviors of children and investigate brain function and irritability. Children with ADHD are being invited to participate as a comparison group as part of a larger research protocol on children with bipolar disorder.

Currently recruiting ages 9-17, with an ADHD diagnosis to participate in 2 outpatient day visits. Children must be medically healthy, and free of bipolar disorder or any mood or other psychiatric disorder that requires treatment. Preference may be given to children who are able to be off stimulant medication for up to 3 days. Children with ADHD will not receive treatment in this study.

Participation includes interviews, research testing, and brain imaging scans.

The studies enroll local participants and are conducted at the NIH Clinical Center in Bethesda, Maryland. All clinical evaluations, research procedures and visits are free of cost. Travel expenses are paid by NIMH. Both parent and child must agree to the child's participation in research. Children and parents are compensated for participation.
