Awareness and improvements in diagnosis have certainly contributed to this... but there must be something else going on. There are records dating back at least hundreds, maybe thousands, of years describing individuals who today may have been diagnosed with autism. Why does it seem to be more prevalent now?

Every two years, researchers count how many 8-year-olds have autism in about a dozen communities across the nation. (The number of sites had ranged from six to 14 over the years, depending on the available funding in a given year.)
In 2000 and 2002, the autism estimate was about 1 in 150 children. Two years later 1 in 125 8-year-olds was believed to have autism. In 2006, the number grew to 1 in 110, and then the number went up to 1 in 88 based on 2008 data.
Boyle acknowledges these statistics are not necessarily representative of the entire United States because the information is drawn from 11 states, not a national cross-section.
However, experts such as Wiznitzer and Goldstein are concerned that the new CDC report is not describing the same autism that was present and diagnosed 20 years ago, when the numbers first shot up.
"Twenty years ago we thought of autism with intellectual disability. We never looked at children who had normal intelligence" -- doctors never considered that high-functioning children had autism too, says Goldstein.
Wiznitzer believes written reports can't definitively determine whether a child has autism. You need to see the child to complete a diagnosis, which the CDC experts did not have the opportunity to do.
