Thank you, Joanna. Now can you cite quality incidence studies which show a substantial increase in autistic spectrum disorders? The CDC's ADDM studies were not incidence studies, and the California DDS data are not suitable for determining incidence (according to the CDDS).
Do you understand how problematic it is to compare 1980s era prevalence studies of autistic disorder with 2000s era rates of all autistic spectrum disorders?
