First off, let me say that I am not the type to be in denial over a diagnosis. In fact, I'm a big fan of labels because, IMO, without them, you can't get proper treatment. So this isn't me reacting in denial to the thought of their being an issue with ds.
That said...his issues go back to birth. He was born pissed at the world. I had a terrible pregnancy (actually, the pg was normal aside from HG, it was the "social disarray" in my life that made it a rough year) and his birth was horrific. Add to that a strong family history of mental illness from his dad's side and the poor bub was doomed from conception.
In infancy, he was high needs. In toddlerhood, he had sensory issues. Starting in early childhood, his symptoms progressed to fit what some call "early-onset bipolar disorder". Yes, I am aware that many in the medical field don't believe in this, but whatever this set of symptoms really is, my son fits the list to a T.
We recently started meds. They are not helping, but that's not the point of this post. The point is that he was recently given a new diagnosis which his pdoc did not mention to me and of which I only became aware when sitting down at an IEP meeting and looking at a form the doctor had faxed straight to the school. In the past, he's been dx with Psychosis-NOS, Mood Disorder-NOS, GAD, and Specific Phobia. Now we can add PDD-NOS to the list.
At first I assumed it was just something the doctor did to ensure the school would accommodate but when I asked her, she said it fit and explained why she felt that way. I always thought PDD was the most severe form of ASD but I guess I was wrong. All the kids I know with that dx are non-verbal and have been severely delayed since birth (or since a particular vaccine in infancy/toddlerhood).
Here is what she based it on: Ds has difficulty with feelings. I say "I love you" and he says "Ok". He is emotionally selfish. Maybe one or two times out of ten, if he is in an upward mood swing, he will answer back "I love you, too". That's it. That's where her dx came from. He developed language right on time, if not early. He has no issues telling me how he feels when he wants something or wants to avoid something (like chores). He can tell elaborate detailed stories, both verbally and written. Communication is absolutely not an issue for him. He is just emotionally constipated. Basically, he's a guy!
I looked it up and the main component of PDD is language delay. Why would a bipolar child who sometimes experiences periods of flat affect be dx with PDD?
