I think it would be unlikely that Asperger's Syndrome (AS) would be misidentified as high IQ; however, a person with Asperger's Syndrome might also have a high IQ. A person with AS will have various symptoms, some of which might cause a misdiagnosis of an attention deficit disorder (ADD or ADHD), obsessive-compulsive disorder (OCD), a learning disability, or other conditions. As an example, it seems unlikely that a medical professional would explain rarely speaking, an intense interest in doorknobs, lack of eye contact, or experiencing extreme anxiety when lights flash as having a high IQ. A person can have both Asperger's Syndrome and a high IQ, only Asperger's Syndrome, or only a high IQ. Some people with Asperger's Syndrome have a high IQ. Most people with a high IQ do not have Asperger's Syndrome.

Down syndrome is the correct term. People who are using "Downs" are speaking incorrectly. Down syndrome used to be called Down's syndrome, but since John Langdon Down did not have nor "invent" this chromosomal abnormality, the correct name is Down syndrome. Countries such as the UK, still use the term Down's syndrome, but shortening it to Down's is not using people first language, therefore, it is incorrect.
