Autism and ADHD often occur together

Almost 30% of young children with autism also show signs of attention-deficit/hyperactivity disorder (ADHD), a rate that's three times higher than it is in the general population, a new study shows.

Kids in the study who had both problems together also tended to have more difficulty learning and socialising than children who had autism alone.
