 April is World Autism Month

One in 59 children in the U.S. is diagnosed with autism today, and research tells us that for people with autism, early intervention leads to the best outcomes. That’s why learning the signs and knowing the steps to take following a diagnosis are so important.

Though the average age of diagnosis is 4, autism can be reliably diagnosed by 18 months in most cases. Not all children with autism show all the signs. Many children who don’t have autism show a few. That’s why professional evaluation is crucial.
