Ok, so I have Mood Disorder NOS and asked my psychiatrist, who is a good one from the Univeristy of Wisconsin--WHAT THE HELLO DOES THAT MEAN? He explained it in a way that maybe anyone who has a child with this dx. can relate to. I "buy" his answer. He said that it's sort of a spectrum. If somebody doesn't have obvious mania/depression, but definately has debilitating mood swings, with anxiety disorder and panic disorder and some OCD they lump it all together and call it mood disorder NOS. That makes me think that soon enough, just like "Autistic Spectrum Disorder" soon the mood disorders will be called "Mood Disorder Spectrum." At any rate, those of you with kids with that dx.--that's what I was told it is. Of course, because of the liable moods, often you need a mood stabilizer. However, in spite of having some really nosedive moodswings, I do best on an antidepressant and benzo. Anyway, this was just FYI (and, of course, maybe some won't agree, but it works for me).
