Yes plenty of people cited a change of diagnostic criteria and thats defenetly a reason. We need to get info that compares LFA diagnosis of today to general autism diagnosis of before to see how much increase there truely is.
Umm, no. LFA is, more or less, "autism AND (mental retardation OR non-verbal)"; the change in criteria did not affect much these points (even before the DSM-III-R, none was required for a diagnosis of autism); then, if the new criteria makes people withj IQ > 70 more prone to be diagnosed with an ASD (instead of being only "weirdos"), also makes more probable that a person with IQ < 70 being diagnosed with an ASD (instead of being only "mentally ret*d")
