What is the Prevalence and Onset of Schizophrenia?
The likeliness of a person developing schizophrenia is 0.3% - 0.7%. It depends on racial/ethnic background, and gender. Episodes of psychosis associated with schizophrenia tend to appear in late adolescence - mid for males, with the peak of onset being around 20-25. For females, onset happens later, typically from 25 until 30.

What is the Prognosis of Schizophrenia?
It is difficult to predict the course of illness. Around 20% of those diagnosed will respond well to treatment. A large number will remain chronically ill needing regular treatment + intervention. Doctors, as yet, haven’t found a way to accurately predict an individuals prognosis after diagnosis.
