Hi Fried, I don't agree that what gets labeled schizophrenia is a "disorder" - that's a value judgment about how people respond to adverse experiences, psychological and biological.
Also do not agree that these problems have a biological origin (if by origin one means cause); that has never been confirmed. What I believe is that there are biological and epigenetic correlates to extreme distress as the person and environment interact.
Lastly, there been many, many accounts of full recovery from a diagnosis of schizophrenia; I thought that issue was already resolved and am always sincerely surprised when people say they think schizophrenia is incurable. I'll paste in here my list of reading of intensive psychotherapeutic approaches to schizophrenia, starting from decades ago and going up till the present, which contains a few hundred cases with many stories of "cure"; I think if people were more familiar with this work they'd be a lot more optimistic:
