Psychosis More Condition_symptoms When Would Psychosis Turn Into Schizophrenia?

When would psychosis turn into schizophrenia? - psychosis more condition_symptoms

I know that you can have psychosis value of their own - but if he is in schizophrenia? Is it a psychosis in life, or has been diagnosed as something else? What if I do not fit the criteria of any other disease? I'm just interested in just that. Thank you.
