CUTTING THROUGH THE PSYCHOBABBLE:
DIAGNOSING AUTISM AND PDD-NOS PER THE DSM-IV IN LAYMANS TERMS
This document was born out of confusion experienced by so many parents about the diagnosis of autism or PDD-NOS. When comparing notes, we discovered that even our physicians did not agree. One woman told us her psychologist said that a diagnosis of PDD-NOS was reserved for children on the spectrum who are curable; others have been told that PDD-NOS is not even on the spectrum! We found that many clinicians seem to take a milder diagnosis and simply label it PDD-NOS.
This document takes the DSM-IV criteria for autism and PDD-NOS and translates it into English. It also attempts to clarify how a diagnosis of PDD-NOS is made. Please note that not all symptoms may not be present every day. Look at typically developing children of same age (peers) and use them as markers. This document is certainly not a diagnostic tool; it was created by and for parents.
To make this easy, (1), (2), (3) are categories, the letters (a), (b); etc that appear under each category will be referred to as symptoms.
DSM-IV Criteria for Autism
A. To be diagnosed with autism, you must have:
o At least SIX (6) of the below symptoms from categories (1), (2) and (3).
o You must have TWO (2) symptoms from (1- Social)
o And ONE (1) each from (2- Communication) and (3 Behaviors and Interests)
o The other one (or more) can be from any of the categories.
Social interaction is impaired, must have TWO from below list of symptoms:
(a) Problems with nonverbal behaviors such as eye contact, facial expression, body postures and gestures used in social situations
o Eye contact different from peers, may only meet eye-gaze of certain people or have total lack of eye contact or anything in between
o Facial expression may seem inappropriate to what the situation warrants, may have blank gaze, may not greet you with a smile, may have same expression on face most of time or any combination thereof
o Body Postures may hold arms close to sides, may try to avoid certain types of social contact, may appear unapproachable due to posture
o Gestures may not respond to a hand held out to shake hands, arms out for hugs etc. May not understand social cues we take for granted

(3) BEHAVIORS AND INTERESTS
Repetitive behaviors, interests, and activities child may get angry if this pattern is interrupted. Must have at least ONE of the below symptoms:
(a) Child is so focused on an interest that to remove the interest will result in a meltdown
(b) Routines or rituals must be followed, they appear to have no function
o Lining up cars is not necessarily playing garage; if you attempt to join in, the child will tantrum, walk away, push you aside, etc.

o If you go to the video store, you must rent The Brave Little Toaster every time or risk a tantrum
(c) Repetitive behavior such as hand flapping, rocking, ear flicking, chewing on clothing, vocal stims, spinning etc. Establish if this is self-stimulatory by doing a functional assessment like the Durand Motivational Assessment Scale: http://www.monacoassociates.com/mas/MAS.html

B. Child is either delayed (not same age as peers) or acts differently from peers in ONE of the following (must be noticeable before age three): (1) social interaction, (2) language as used in social communication, or (3) pretend play.
C. Child does NOT have Retts or Childhood Disintegrative Disorder
299.80 Pervasive Developmental Disorder, Not Otherwise Specified
PDD-NOS is a diagnosis by exclusion. If a child presents with some symptoms from (1), (2), and/or (3), and their pattern of symptoms is not better described by one of the other PDD diagnoses (i.e., Autistic Disorder, Aspergers Disorder, Retts Disorder, or Childhood Disintegrative disorder) then a professional might decide that a diagnoses of PDD-NOS is warranted.
When comparing PDD-NOS to Autism, PDD-NOS is used when a child has symptoms of autism as above, but not in the configuration needed for an autism diagnosis. Social component is where the most impairment is seen. Children who fail to meet criteria for autism and dont have adequate social impairment typically have a developmental disability, and their symptoms can by accounted for by that.
Looking at above description:
299.00 Autism - To be diagnosed with autism, you must have at least 6 of the below symptoms from (1), (2) and (3). You must have two symptoms from (1) and one each from (2) and (3) the other two can be any of the other symptoms.
PDD-NOS is most often diagnosed when children have significant social impairments, but dont have the symptoms in area (3). A child with PDD-NOS may have the same (or more, or less) number of symptoms as a child with autism, but instead of having 2 from #1 and one each from #2, the child might have 1 symptom from #1 and one from #2, plus two from #3.
A diagnosis of PDD-NOS is not necessarily a less-severe one than a diagnosis of autism, but can be sometimes.
Severity of any spectrum disorder can be determined by the amount and severity of symptoms listed above.
It is imperative to obtain a thorough psychological assessment performed. If you do not understand during any part of the assessment, ask questions. You should feel comfortable to go home and digest the information given to you, form any questions or concerns and contact the diagnosing clinician to get your answers.
