No, they're not the same. Schizo affective disorder means that someone has characteristics of both bipolar (i.e. low or high mood) and schizophrenia (i.e. delusions or hallucinations). I think people have debated as to whether it should really be its own disorder. It seems confusing to me too because I thought people diagnosed with bipolar could have delusions without being considered to have a type of schizophrenia, but I'm not sure if they can have hallucinations.

Basically its the official name for when bipolar and schizophrenia run into each other. But I'm no expert!
