Thirty-two patients with a research diagnosis of chronic schizophrenia were studied using structured clinical scales for premorbid adjustment, clinical symptomatology, and social deterioration. By computed axial tomography (CAT), ventricle-brain ratio (VBR) and cortical atrophy were assessed. The relation between the clinical variables and CAT findings was assessed using linear correlation. CAT-based subgroups were compared using univariate analysis of variance. Previous findings of ventricular enlargement and cortical atrophy in some schizophrenics were replicated. Premorbid asociality and social deterioration were found to have a modest, positive relation with CAT findings but formal thought disorder had a negative relation to ventricle size. There was no relation between the negative symptoms and CAT measures. Within the CAT-positive group the presence of cortical atrophy appeared to be associated with a more severe illness compared with those with ventricular enlargement but the sample sizes were too small to obtain any significant differences.
