Mean values and standard deviations. SCHhigh: N = 8 ; SCHlow: N = 9, apart from #) "Time since medication", as four patients were drug-naïve. The SAPS and SANS scores are given within three dimensions of schizophrenia psychopathology: Positive (global hallucinations + global delusions), disorganised symptomatology (global Formal thought disorder + global bizarre behavior + SANS item inappropriate affect) and negative (all global scores of the SANS except attention). The negative score stratified the sample. "Duration of illness" is measured as time since first psychiatric contact. **) p < 0.01. Two of the non-psychotic patients were in the SCHhigh group. In the SCHhigh group three patients had only received traditional type neuroleptics, one had only had modern antipsychotics and one patient had tried both types of treatment. In the SCHlow group two patients had received traditional type neuroleptics, and six had received modern type antipsychotics.
