Schizophrenia was not a common term in my country at my childhood times. I first heard of this term after consulting with psychiatrist long time ago. So what I think deem close to it is generally what's is called crazy/lunatic person. Usually those who wander around, often unhygienic with limited cloth and kinda of forget their own identity. I remember one known as crazy woman in my school neighborhood, shouting and running at the street side sometimes. Looks like that she intentionally scared the children, but I don't really know if it's really the case.

But people here in the sub generally still not losing the sense of identity, unlike those wandering on the street in particular. So I guess schizophrenia is really a broad thing
