Nearly 1 In 3 With Autism Have ADHD Too, Study Finds
Almost one-third of children with autism also have attention deficit hyperactivity disorder and symptoms appear to be more severe in kids affected by both conditions, new research suggests. The findings come from a long-term study of 162 children who were tracked starting when they were still infants or toddlers. By the time the kids reached ages 4 through 8, researchers found that 63 had autism. Of those with the developmental disorder, parent reports indicated that 18 of the children - or about 29 percent - also had clinically significant symptoms of ADHD.
