Individually designed programs best meet the needs of a person with autism. Those with autism should be learning, living and working in settings where there is ample opportunity to communicate and interact with others who have the skills they lack.
There are no medical tests for diagnosing autism. An accurate diagnosis must be based on observation of the individual’s communication, behaviour, and developmental levels. However, because many of the behaviours associated with autism are shared by other disorders, various medical tests may be ordered to rule out or identify other possible causes of the symptoms being exhibited.
The characteristic behaviours of autism spectrum disorders may or may not be apparent in infancy (18 to 24 months), but usually become obvious during early childhood (24 months to 6 years). While there is no one behavioural or communications test that can detect autism, several screening instruments have been developed that are now used in diagnosing autism. When autism is suspected, your child will need to be referred to someone who specializes in diagnosing autism spectrum disorders. This may be a developmental pediatrician, a psychiatrist or psychologist. Other professionals may be included who are better able to observe and test your child in specific areas.
