Types of Autism
This section of the website contains information about the different types of autism – also known as autism spectrum conditions, autism spectrum disorders, ASDs or pervasive developmental disorders.
There are four main sub-types of autism
- Autistic disorder, also known as autism, childhood autism, early infantile autism, Kanner’s syndrome or infantile psychosis.
- Asperger syndrome, also known as Asperger’s disorder or simply Asperger’s.
- Childhood Disintegrative Disorder, also known as CDD, dementia infantalis, disintegrative psychosis or Heller’s syndrome.
- Pervasive Developmental Disorder (Not Otherwise Specified), also known as PDD (NOS) or atypical autism.
Rett syndrome is no longer considered to be a sub-type of autism, although individuals with Rett syndrome may display autistic-like symptoms.
The term ‘autism’ is sometimes used interchangeably with the term ‘autism spectrum disorders’ to mean any or all of the different forms of ASD. It is also sometimes used interchangeably with the term ‘autistic disorder’.
