The exclusion by autism self advocates of the intellectually disabled autistic population occurs despite the fact that many persons with Autistic Disorder are intellectually disabled. The ICD-10 mentions this fact expressly in its description of Autistic Disorder:
All levels of IQ can occur in association with autism, but there is significant mental retardation in some three-quarters of cases.
* autistic disorder
* infantile autism
* infantile psychosis
* Kanner's syndrome
Settlement.org a web site of the 2009 Ontario Council of Agencies Serving Immigrants speaks about intellectual disabilities with express reference to autism:
Intellectual disability is a term used when a person has certain limitations in mental functioning and in skills such as communicating, taking care of him or herself, and social skills. These cause a person to learn and develop more slowly than a typical person. Individuals with an intellectual disability may take longer to learn to speak, walk, and take care of their personal needs such as dressing or eating. A person with an intellectual disability will require some level of support for his or her entire life. Intellectual disabilities are sometimes called "developmental disabilities."
There are more than 200 known causes of intellectual disability. Some common examples of intellectual disability are:
- Down syndrome
Refusal by anyone, including the alleged Autism self advocacy organizations, to recognize the ID Autistic population is just another form of bigotry, discrimination and intolerance. Such exclusion contributes to the stigmatization of those with MR/ID generally and autistic persons with MR/ID specifically.
