Autism and Related Conditions
Other conditions may be associated with autism in one or more of the following ways:
- Autistic Spectrum Disorders (Pervasive Developmental Disorders) all share some features in common. Often, other PDDs are considered variant forms of autism rather than completely separate conditions.
e.g. Asperger Syndrome
- Autistic behaviours may be mis-diagnosed as being the result of another condition.
e.g. Personality Disorder
- The behaviours of another condition may be mis-diagnosed as autism.
e.g. Landau Kleffner Syndrome
- The condition may be co-morbid with (occur in the same person at the same time) autism.
In most cases, a Pervasive Developmental Disorder is the primary diagnosis, with secondary ones only being warranted if the symptoms are very severe and outside of the range normally accounted for by the PDD. For example, people with Asperger Syndrome tend to be clumsy, so coordination problems are considered part of the AS, and a diagnosis of co-morbid Dyspraxia is not usually warranted. The same situation occurs frequently with ADD/ADHD, Sensory Integration Dysfunction, and OCD and less frequently with most of the other conditions in this section.
