New research has identified more genes associated with attention deficit hyperactivity disorder (ADHD) and found an overlap between some of these genes and those found in other conditions such as autism spectrum disorders (ASDs).  Researchers studied the DNA of 248 unrelated patients with ADHD; 19 of 248 patients had inherited changes.  Within this group of inherited changes, researchers also found genes previously identified in conditions such as ASD; conversely they found ADHD genes in nine of the patients previously diagnosed with ASD.  The study appears in Science Translational Medicine(http://stm.sciencemag.org/content/3/95/95ra75).
