In broad terms, there are 2 main “types” of autism on the spectrum; “Kanner/Classic Autism” where in addition to the autism, there is also intellectual impairment. Statistically, it is consider that 76% of people with autism have “Kanner/Classic” Autism (i.e also have intellectual impairments in varying degrees), where as 24% of people with autism do not have any intellectual impairments, nor speech delay in early childhood years and these people are classified as having “Asperger Syndrome”, displaying a “normal” or more than often, above average intellectual ability.

|
Regardless of the manifestation of autism, ALL people on this spectrum, are affected in different degrees, by the “Triad of Impairments” that causes a disturbance in quality of development in the following areas:-
|
|
|
1. Language and Communication. 40% of people with “Kanner/Classic autism” never speak nor fully understand verbal communication. People with Asperger Syndrome with seemingly fluent speech will have areas of their communicative abilities that are adversely affected; for instance an extreme difficulty in reading non-verbal communication such as facial expressions, body language etc.
|
|
|
2. Social Interaction. For a person with autism, the area of the brain that enables us to understand other people’s emotions and feelings is altered and thus a person with autism cannot fully understand the complexity of the thoughts of people around them and the resulting social interactions.
|
|
|
3. Imagination and Creative Play. A person with autism usually becomes trapped by rigid thought patterns and behaviours. Difficulty in understanding abstract concepts and the day-to-day jargon we regularly use flippantly in conversation, such as “It is Raining Cats and Dogs”, “Throw the baby out with the bathwater”, “I nearly died laughing” …….
