Multilingual Schizophrenia

When schizophrenia is placed in the same set of Quizlet flashcards as adult enuresis (don't search that up), antisocial personality disorder, and kleptomania, it almost seems normal. Schizophrenia almost lessens the gravity of all of the aforementioned disorders, almost seems to decrease their average severity. Because of this, schizophrenia somehow faded to the back of my mind. (You searched up adult enuresis, didn't you?)

Then, I saw this:

This video reminded me of the harshness of schizophrenia, of the difficulties patients face in their everyday lives. It also got me wondering this: How will schizophrenia manifest itself in multilinguals?

Initially, I thought schizophrenia would show its form in a twisted amalgamation of every language the patient speaks, in a way should make sense but doesn't. 
But, as in most cases, initial hypothesises are very wrong and so was this one.

On this Reddit discussion, most reported either hearing voices in both languages or hearing voices in their primary, first language. With children that had been taught multiple languages simultaneously, the former seemed to be more common.

I don't think anyone has a clear answer, though. But I think this is part of what makes clinical and abnormal psychology particularly interesting subjects—that they're still subjects that are very much developing.
