I liked Pine's clarification very much. I removed the entire "treatment" section, and the more I think about it the more I think it should stay out. I think it's too specific to the psychiatric syndromes, and belongs in the articles on the different syndromes, not in this overview on the mood. The treatment regime for depression in BD is very different to that in BPD, and they both differ from that in MD. Anyway, that's what I think at the moment. 

I have to take an indefinite Wikibreak, so won't be watching for a while. Regards.
