The problem with schizophrenics is that the schizophrenic process is so complete and totalizing that it essentially swamps over all sorts of other or lesser symptoms.
All you see is the schizophrenia, and its hard to see if there are anxiety, mood (Axis 1 or symptomatic) or especially personality disorders (Axis 2) underneath there. It’s like there’s a tidal wave coming in (the schizophrenia), and you are running around your house looking for roaches (other disorders). Well, the wave is going to swamp all those roaches, and even if they are there, at some point all you will see is the wave, and the only thing that will matter is the wave, as the roaches will be swamped out so to speak.
Also schizophrenia itself can feature prominent anxiety at times (for instance that the FBI is after them), although anxiety is not typical a primary feature of schizophrenia.
Schizophrenics are often depressed, but it seems like depression is part of the schizophrenia itself. Obviously when depression is part of core schizophrenia as a symptom, it makes it hard to tell that apart from a depression arising often from the depressing effects of the illness itself.
Axis 2 (personality disorder) problems are going to get swamped out too, not to mention the fact that having schizophrenia alone has a devastating effect on personality.
