Researchers at the Kennedy Krieger Institute found that nearly one-third of children with autism also have ADHD.
The researchers found that school age children (4 to 8 years) with both autism and ADHD had significantly greater social and cognitive problems compared to children with autism alone.
“We are increasingly seeing that these two disorders co-occur and a greater understanding of how they relate to each other could ultimately improve outcomes and quality of life for this subset of children,” says Dr. Rebecca Landa, senior study author and director of the Center for Autism and Related Disorders at Kennedy Krieger. “The recent change to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) to remove the prohibition of a dual diagnosis of autism and ADHD is an important step forward.”
The study was published in Autism: The International Journal and Practice.
