In 2015, the Australia Health Department stated that it does not collect data on the prevalence of autism.Autism appears to be on the rise. In 2015, autism made up 31% of the National Disability Insurance Scheme (NDIS) participants. Asperger's Syndrome is part of the autism spectrum. (This does not mean that 31% of the entire Australian population have Asperger's Syndrome or other forms of Autism.)
There is no such thing. Down syndrome and autism are separate conditions.
Asperger's syndrome
Aspergers Syndrome can be called: Aspergers, High-Functioning Autism, or you could just call it Autism, because it's a type of Autism.
Some people have savant syndrome. They may have exceptional skills in art, music, or computation. They have had damage to the left anterior temporal lobe. About half of them have autism.
Her youngest son has Down's Syndrome, but she has a nephew with autism.
Including but not limited to: Autism (ASD), Asperger's Syndrome, Kanner's Syndorome, Pervasive Developmental Disorder (PPD), and Rhett's Syndrome.
From interviews with her about the movie Mozart and the Whale in which she played a character with Asperger's Syndrome, it would seem very unlikely that she has it. She said that she learned about autism and Asperger's Syndrome when working on the movie. She also explained that "they" (people with autism or Asperger's Syndrome) see the world from a different perspective. She seems to use "they" and "their" for people with autism or Asperger's Syndrome, while using "we" and "us" for people without autism or Asperger's Syndrome, so I would assume that she does not have it.
Autism isn't a disease or a virus, thus there are no strains of autism. Autism is just autism, it was previously split up into Autism Spectrum Disorder (Classic Autism), Asperger Syndrome, Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS), childhood disintegrative disorder, and Rett Syndrome - now all are merged under the Autism Spectrum Disorder diagnosis.
Asperger's Syndrome is a subtype of autism spectrum disorder (ASD), therefore they are not separate conditions. In the DSM-5, Asperger's Syndrome is no longer a diagnosis, it has been folded into the broader category of ASD.
One types is Asperger's Syndrome
When she was a child, Temple Grandin was diagnosed as having autism. If she were being diagnosed today, it would probably be labeled Asperger's Syndrome.
