Study evaluated 157 people diagnosed with ASDs and found that everyone diagnosed with AS really had HFA instead. It's no big deal because they're both similar and part of the autism spectrum. I just posted it because I think some people here may find it interesting.

Does DSM-IV Asperger's disorder exist?

DSM-IV criteria for autistic and Asperger's disorders were applied to 157 children with clinical diagnoses of autism or Asperger's disorder. All children met the DSM-IV criteria for autistic disorder and none met criteria for Asperger's disorder, including those with normal intelligence and absence of early speech delay. The reason for this was that all children had social impairment and restricted and repetitive behavior and interests (required DSM-IV symptoms for both autistic and Asperger's disorders) and all had a DSM-IV communication impairment (which then qualified them for a diagnosis of autistic disorder and not Asperger's disorder). Communication problems exhibited by all children were impaired conversational speech or repetitive, stereotyped, or idiosyncratic speech (or both), which are DSM-IV criteria for autism. These findings are consistent with those of 5 other studies and indicate that a DSM-IV diagnosis of Asperger's disorder is unlikely or impossible.

I don't know whether I agree with this but 6 studies seem convincing. I think this may be a good thing if it's true that everyone diagnosed with AS really has autistic disorder because that would mean all of us are more similar. I'm curious whether those who are AS had symptoms before age 3.
Please Note - I'm not trying to convince anyone of anything or doubt anyones diagnosis. I just came across this while looking for something else and think it's interesting.
Difference between autistic disorder and AS:
For autistic disorder, there must be "Delays or abnormal functioning in at least one of the following areas, with onset prior to age 3 years: (1) social interaction, (2) language as used in social communication, or (3) symbolic or imaginative play.
For AS, "There is no clinically significant general delay in language (e.g., single words used by age 2 years, communicative phrases used by age 3 years)."
