Recent research is providing a deeper understanding of how genes and environmental factors interact to influence its development.
A new genomic study of families whose members had ADHD showed they all had specific features in certain genes. The identification of such patterns may help improve the diagnosis of ADHD. Genetically based diagnosis of ADHD could provide earlier detection and treatment. This is especially critical now that 10% of children in the U.S. are being diagnosed with ADHD.
