title: Computerised tomography in newly diagnosed schizophrenia and schizophreniform disorder. A controlled blind study.
abstract: Patients with newly diagnosed schizophrenia (n = 27) or schizophreniform disorder (n = 22) and 24 healthy volunteers were investigated by CT scan, the investigators being blind to subject status. The patients had never received medication or had been treated only briefly with neuroleptics. The patients had significantly smaller brain volume and brain length than the controls. The patients had greater sulcal enlargement in the case of both Sylvian and interhemispheric fissures and surface sulci in the frontal and parietal regions. The sulcal enlargement was more pronounced in male patients and on the left hemisphere. The study revealed no enlargement of the lateral ventricles and only a trend towards enlargement of the third ventricle in the patients. The findings were not explained by substance abuse or level of education.
