I've been going over this in my head over and over again. The leading theory for schizophrenia is based on a flawed logic at best. The fact they use dopamine blockers and they work somewhat has nothing to do with the actual pathology of the illness.  


A 1983 study measured waste dopamine levels in spinal fluid and noticed the non-medicated patients had normal levels and the medicated patients had more. What this means is that your brain actually produces more dopamine to compensate for the dopamine blockers anyway.
