  • Title: Cerebral ventricular size in major depressive disorder: association with delusional symptoms.
    Author: Targum SD, Rosen LN, DeLisi LE, Weinberger DR, Citrin CM.
    Journal: Biol Psychiatry; 1983 Mar; 18(3):329-36. PubMed ID: 6404312.
    Abstract:
    Computerized tomograms (CT scans) and neuroendocrine challenges (TRH stimulation test and dexamethasone suppression test) were completed in 38 melancholic depressed hospitalized patients. There were no significant differences in ventricular size between delusional and nondelusional depressives. However, 5 of 20 delusional depressives (25%) in contrast to none of 18 nondelusional depressives had ventricular brain ratios greater than 2 standard deviations from the mean of 26 neurological controls. There were no demographic, clinical, or neuroendocrine differences between patients with enlarged ventricles and those with normal CT scans. Two of 5 patients with large ventricles were rehospitalized within the 1st year of ascertainment in contrast to 3 of the other 15 delusional depressed patients. The possible relevance of cerebral ventricular size for depressive disorder is discussed.
