Here is the truth about anti-psychotics for schizophrenia:

1/3 of people with schizophrenia will respond very well to anti-psychotics (lead a fully functional life with minimal or no relapses)

1/3 of people with schizophrenia will respond moderately well to anti-psychotics (they will be functional for stretches of time, but relapse periodically...this is called a 'relapse-remitting' disease course)

1/3 of people with schizophrenia will be chronic non-responders to anti-psychotics (never really able to hold down a job and support themselves)
