Lateral ventricular enlargement and clinical response in schizophrenia.
The relationship between enlargement of the lateral ventricles in the brains of schizophrenic patients and clinical response to neuroleptic treatment, as assessed by the ventricle-brain ratio (VBR) and psychopathology scores, was studied in a sample of 39 patients with schizophrenia or schizoaffective psychosis during a drug-free washout and after 3 1/2 weeks of treatment with either haloperidol or thioridazine. There was a weak, but statistically significant positive relationship between VBR and improvement on BPRS Psychosis factor scores after 3 1/2 weeks of treatment, and a negative correlation between VBR and baseline (washout) scores on the BPRS Anergia factor. Patients with enlarged VBRs, as defined by two criteria, also tended to show a better response to neuroleptics than patients below these criterion values.
