This study helps to refute the supposition made by some researchers that autism’s epidemic may only be due to “diagnostic substitution”.
Excerpt: “They have suggested that ‘diagnostic substitution’ accounts for an apparent increase in the incidence of autism in California that is not real. This hypothesized substitution is not supported by proper and detailed analyses of the California data.”
