Brain Imaging in Children With AD/HD
The purpose of this study is to use brain imaging technology to study the connections between brain regions in children with attention deficit hyperactivity disorder (AD/HD), and comparing them to children without AD/HD.
This study will build upon previous brain imaging studies of healthy volunteers and children who have AD/HD. This study will use diffusion tensor magnetic resonance imaging (DT-MRI) to visualize and measure certain parts of the brains of identical twin pairs in which one twin has AD/HD, combined type.
Participants in this study 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. Prior to the MRI, participants will have a training session in a simulated MRI scanner to learn how to lie still during MRI scanning. Participants may be asked to return for a follow-up scan in about 2 years.
