This is something I have been thinking on lately. If you look at the range of meds used to treat Bipolar it is a lot longer than say that of Schizophrenia and some BP don't respond well to any combination of these meds which makes me wonder if maybe a lot of people are being misdiagnosed as BP when its something else. Or maybe another unrecognised illness that mimics BP, schizoaffective etc to a certain degree.
