Autism spectrum disorder (ASD) affects about 1 in 59 children. The American Academy of Pediatrics (AAP) recommends that all children be screened for ASD at their 18- and 24-month well-child checkups. Research shows that starting an intervention program as soon as possible can improve outcomes for many children with autism.
Autism differs from person to person in severity and combinations of symptoms. There is a great range of abilities and characteristics of children with autism spectrum disorders — no two children appear or behave the same way. Symptoms can range from mild to severe and often change over time.
