Treatment resistant chronic psychopathology and CT scans in schizophrenia

In order to examine the relationship between the neuroleptic resistant chronic psychopathology and CT findings in schizophrenia, 25 schizophrenics who had been treated well and were in a stable condition were assessed for positive and negative symptoms, CT findings, medication, and the clinical course of illness. Correlational analysis showed that there was a group of patients who had comparatively small ventricles and presented treatment resistant positive symptoms, and another group of patients who had larger ventricles and lacked positive symptoms. Negative symptoms showed a tendency toward positive correlation with atrophic CT changes of cortices. Literature on CT findings and symptomatology was critically reviewed. The importance of the more chronic positive symptoms correlating to CT findings in schizophrenia were discussed.
