Simple, objective, linear, and density measures were used to evaluate by computed tomography (CT) the cerebellum-fourth ventricular region of 23 chronic schizophrenic patients and 23 normal controls. Our data suggest that a subgroup of chronic schizophrenic patients have cerebellar atrophy associated with a strong but nonsignificant trend toward increased(More)
A comprehensive quantitative computed tomography (CT) study of the diencephalic region of 23 chronic schizophrenic patients and 23 normal controls was done. The third ventricle width, the Sylvian fissure widths, and the densities of the head of the caudate nucleus, thalamic nucleus, and medial temporal lobe were measured. In the schizophrenic patients,(More)
A review of the literature on the personalities, mental health, and professional status of psychiatrists was the basis of a questionnaire designed to assess perceptions of these characteristics by psychiatrists themselves and by their medical colleagues. The 374 physician respondents were divided into two groups, psychiatrists and nonpsychiatrists, and(More)
There are numerous reports of lateral cerebral ventricle enlargement on computed tomography (CT) in schizophrenics, but the significance and its relationship to traditional notions of organicity remain unclear. Therefore we studied a subgroup of chronic schizophrenics who had lateral ventriculomegaly (and also cortical hyperdensity) on a battery of relevant(More)
Based on recent computed tomography (CT) studies that have suggested the presence of distinct structural abnormalities in the brains of chronic schizophrenics, the authors evaluated 23 chronic schizophrenics and 23 controls by CT, using linear and area lateral ventricular measures, sulcal and Sylvian fissure widths and cerebral density measures. Technical(More)
Nonsuppression on the dexamethasone suppression test (DST) in schizophrenics has been reported by three independent groups. To elucidate the significance of this finding a schizophrenic cohort was tested on a wide range of parameters: computed tomography (CT), electroencephalography (EEG), the Halstead-Reitan Neuropsychological Battery (HRB), platelet(More)
Twenty-three chronic schizophrenic patients and 23 controls, all males between 20 and 40 years of age, were evaluated by CT scan. The lateral, third and fourth ventricles, the Sylvian fissures, and the largest sulcus from each of the frontal, parietal, and occipital lobes, were measured in order to determine whether the previously reported ventriculomegaly(More)
