I typed "bipolar symptoms in children" into google and it came up with this article.

Reading this, it makes it fairly clear to me J would not be suspected of having Borderline (BPD). The trouble is, perhaps, when one starts looking for diagnoses everywhere? A friend of mine's son, for example, is what one would call
very spirited. He's 8 now, and has calmed down a lot since I first knew him when he was 2, when he was very hyperactive, oppositional, etc - but also very sweet. He is still rather rude to his parents and gets very upset on occasion, but is basically a good kid who although not academic, gets on okay in school. There has never been any question that he "suffers" from anything but if one wanted to, one could maintain that he had this or that disorder.... If it were not for J's hyperactivity, neither I nor anyone else would have started thinking there was something "wrong" with him - he would just be seen as a difficult or turbulent child, I think. But there is the hyperactivity and it does seem to point to something else... ADHD with probably ODD seems to fit him, there's no reason to suppose anything else is going on. And I don't say that because I'm denying anything or making some judgement about other conditions
Keista - when you say you firmly believe that ADHD/ODD diagnoses are something else, do you mean you believe they are actually misdiagnoses for other conditions? Do you not think that ADHD is often co-morbid, as I believe they say, with other conditions, including ODD? Which, although many people here say does not "exist" by itself, does actually make sense to me as a separate diagnosis? But even then, when you read about ADHD, many people talk about the impulsivity leading to aggression in some cases, without bringing in the notion of ODD so even then it is not straightforward. I'm in no position of expertise, having met or known few other ADHD children, but I have
read an awful lot about it now...
