The CDC is now revising its autism rate figure from 1 in 150 to 1 in 100. Watch for the usual bright lights to trot out the 1994 DSM definition change to rationalize this very dramatic increase in autism rate estimates. From 1 in 500 to 1 in 250 to 1 in 166 to 1 in 150 to 1 in 100.
Amazingly the same factors - diagnostic definition change, increased social awareness etc are trotted out each time to deny that autism is really increasing. This happens almost as soon as the estimate is changed and without any science to back up the claim. Anything as long as we can deny that autism rates are really increasing.
Amazingly, US Secretary of HHS Kathleen Sebelius has, according to the Age of Autism, called for more genetic as opposed to environmental autism research to explain the increase.
Incredible. Someone should change her talking points.
