From the CEC Smart Brief:
A new study by a University of Wisconsin-Madison scientist casts doubt on data showing a dramatic increase in autism. According to the study, federal statistics on the growth of autism are inaccurate, in large part because methods used to count students are faulty. It also points out the definition of what constitutes autism has changed, and that not all states use the same diagnostic guidelines. Milwaukee Journal Sentinel (free registration) (4/3)
