Autism was not clearly defined until 1980 when the disorder was included in the DSM-III. Before that time, some cases of autism spectrum disorder may have been mistaken for other conditions. Between 1995 and 2011, the DSM-IV grouped Asperger’s Syndrome and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) with autism. Asperger’s syndrome was an autism spectrum disorder marked by strong verbal language skills and, often, high intellectual ability. PDD-NOS was a more general diagnosis for people who did not fit clearly into the other two categories. Families who care for an autistic child face added stress from a number of different causes.

A study of more than 4.9 million births that took place in the U.S. state of California between 1990 and 1999 revealed that about 5 percent of the nearly 12,160 children who later developed autism were born to older mothers. Mothers 40 years or older had the highest risk of giving birth to a child who would later develop autism. In contrast, older paternal age was a risk factor only when maternal age was 30 or younger. The underlying reasons for those associations, however, were unclear.
