Who should be evaluated for autism or Pervasive Developmental Disorder (PDD)?

In every child who has any type of speech delay, the question of autism or Pervasive Developmental Disorder (PDD) not otherwise specified must arise. Recent recommendations by the American Academy of Neurology (AAN) specify some general early guidelines in that regard. These include:

No babbling by 12 months
No pointing or waving bye-bye by 1 year
No single words by 16 months
No spontaneous 2-word sentences (for communication, not repetition) by 2 years
Any loss of acquired speech or communication skills at any age

Several speech developmental screening and rating scales are suggested by the AAN but the above guidelines cover the vast majority of children that require a more specific evaluation.

Thanks Elise. I had my difficult child speech evaluated after 3yrs old. He babbled incessently but it was very difficult to understand him. He was considered age appropriate but within a month he spoke very fluently in sentences. This has become typical of learning pattern. He is delayed, then the door opens and he leaps forward.

His communication on the other hand has been more difficult.
There were times when he had his own "words" for things,when younger.
He has a difficult saying what he means especially if he is emotional.
I do not believe his speech and communication is N/T although he is very articulate and highly verbal.
Thanks for the guidelines though.
