Summary
We wanted to compare dopamine D2 receptor activity, brain structure, brain function, sensory gating and cognition in neuroleptic-naive schizophrenic patients and matched healthy controls. Additionally, we wanted to examine the effects of 3 months of treatment with either low doses of a typical or an atypical antipsychotic compound on the same functions. The hypotheses were that schizophrenic patients suffered from disturbances in brain function and structure, information processing, and extrastriatal D2 receptor activity, and that these disturbances would be related to each other and to psychopathology. Additionally, we expected the atypical compound to have an effect on some of the disturbances in information processing, and that the atypical compound - in contrast to the typical drug - would show extrastriatal over striatal selectivity.
