An estimated 2.8 percent children have ever been diagnosed with autism spectrum disorder (ASD) and 2.5 percent currently have ASD, revealed national survey data for 43,000 U.S. children. Among 1,115 children with current ASD, almost 30 percent aren't treated with behavioral therapies or medication.
ASD is a neurodevelopmental disorder marked by social impairments, communication difficulties, repetitive behaviors and restricted interests.
Among children with ASD who were treated, almost 64 percent received behavioral treatment and 27 percent received medication. In the study, which used data from the 2016 National Survey of Children's Health, the frequency of ASD among children varied by state.
