How is PDD diagnosed?
The diagnosis of PDD is clinical, meaning "what you see is what you've got." One needs to meet specific diagnostic criteria for the different conditions, but the general requirements are that one must have symptoms that belong to the three main areas of impairments:
- Social interactions
- Repetitive stereotype behavior
- Severe impairment in speech, social skills, or repetitive stereotyped behavior
- A simplified way of understanding the diagnosis of autism is looking at the PDD assessment scale questionnaire.
