Neurobiological Basis of Response to Vyvanse in Adults With ADHD: an fMRI Study of Brain Activation

The purpose of this study is to determine the effects of Vyvanse, an FDA approved medication used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD), on brain activity in adults with attention-deficit hyperactivity disorder (ADHD). Participants may qualify for participation in this study because they have ADHD and are willing to participate in two Functional Magnetic Resonance Imaging (fMRI) scans and receive Vyvanse for treatment of their symptoms. Another purpose of this study is to collect and bank samples of blood for research to examine how genes influence brain activation seen during the brain scans. The study also seeks to find out whether certain genes are related to ADHD. Participants' entire genetic makeup will not be determined from this sample.
