"The increase in prevalence of the PDDs has a threefold
explanation. First, in 1994, with the release of the
Diagnostic and Statistical Manual of Mental Disorders
, 4th edition (DSM–IV), there was a broadening of the diagnostic criteria
for autism. The DSM–IV also added criteria for Asperger’s
syndrome and clarified the criteria for PDD-NOS. Finally,
better assessment methods have provided clarification across
PDD diagnoses and improved the demarcation between
PDD and non-PDD cases. Thus, more recent studies have
overcome the systematic undercount of PDD cases in previous
studies."
