Attention Deficit Hyperactivity Disorder Research Study
|
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.

Attention Deficit Hyperactivity Disorder Research Study
|
Brain Imaging of Twins with Attention-Deficit/Hyperactivity Disorder
|
The purpose of this study is to use brain imaging technology to study the connections between brain regions in a twin with Attention-Deficit/Hyperactivity Disorder (ADHD) compared to their twin without ADHD. Participants in this study must be under the age of 21 years. They will be screened with questionnaires and interviews, psychometric testing, and a physical examination. Participants' medical and educational records may be reviewed. Participants will undergo an MRI scan of the brain.
