Autism-World

Ask??????What authority puts the rate is 1 out of 166?
What forms of autism are included in that rate? PDD-NOS, Rett Syndrome?

What are the stats of the different types of autism separately?
Who thinks the 1 out of 166 stat is bogus? Why?

Answer??????Part of the confusion is there is “Autism Spectrum Disorder” which includes Asperger’s & Retts, PDD-NOS & other types. And then there is “Autism Disorder” which is has more of a strict diagnostic criterium. So when a site refers to a study that estimates that 3.4 of every 1,000 children have autism, is it which is it refering to? The broad term, “Autism Spectrum Disorder” or the narrow term “Autism Disorder”?

Rett Syndrome is 1 out of 10,000 -15,000.
CDD (childhood degenerative disorder) is 2 out of 100,000
Asperger’s may be 25 out of 100,000

I’m still looking for PDD-NOS & Autism Disorder rates.

At the rate of 1 out of 166, there would be 600 out of 100,000. Adding Retts (7-10 out of 100,000), CDD (2 out of 100,000), & Asperger’s (25 out of 100,000), together comes up with 34 – 37 out of 100,000. So unless AD & PDD-NOS combined totals 565 out of 100,000, the statistics are highly suspect.

In 2003 approximately 141,022 children (or 1 out of 400) were served under the “Autism” classification for special education services. This would not include the high funtioning kids. Most of the kids who would have gone undiagnosed 25 years ago would not be in this group. This would likely include Retts, PDD-NOS, & CDD as well as strict autism.
