Spike in autism caused by a shift in diagnosis, Chapman study finds
Orange County Register

Vaccines, environmental triggers, parental age – it’s highly unlikely that any of those are driving the dramatic increase in the autism rate, a Chapman University study found. Rather, the study concluded the rate – which is now 1 in 50 in Orange County, the highest in the state – can be “almost completely” explained by a change in how the disorder is diagnosed. Two Chapman researchers analyzed 15 years of state special education eligibility data and found many students who once would have been considered to have a condition called Specific Learning Disability are now told they have autism.
