Diagnosis isn't all that important. I'm diagnosed as Bipolar I, so I take 1 atypical, 2 anti-seizure drugs, and wellbutrin. If I was diagnosed Schizoaffective or Schizophrenia with mood issues, the drugs would hopefully be more or less the same, although I don't think they use Wellbutrin in people labeled with Schizophrenia very often.

From what little I've read on it, the big deal with Schizoaffective is prognosis. The long term outlook for the manic form is better than Schizophrenia, not quite as good as Bipolar I. I think the depressive form is closer to Schizophrenia in terms of prognosis.

Of course, there's a lot of heterogeneity within the Schizophrenia diagnosis. that's one thing I can't stand about the label Schizophrenia. Its more like an invalidation, a condemnation, than a diagnosis. You can be Schizophrenic if you're too sad, too happy, talk too much, talk too little, are too active, not active enough, etc. They really need to start breaking Schizophrenia up into different diagnoses. In Japan, they got rid of Schizophrenia as a diagnosis, because it was so stigmatizing.
