Attention Deficit Hyperactivity Disorder (ADHD) often appears to run in families, and research studies have suggested that there may be a genetic component to this disorder. Individuals diagnosed with ADHD may have close blood relatives with the disorder. Scientists believe that ADHD is a complex disorder that probably involves at least two genes. Non-genetic causes such as abnormal brain development, brain injury or environmental factors are also believed to play a role in the disorder.
One of the long-range goals of this study is to facilitate the diagnosis of ADHD and the development of improved treatments, possibly including individually tailored treatments. The purpose of these Web pages is to introduce the study to families with children who have been diagnosed with ADHD, and to recruit interested families to enroll in this study.
