  • Title: The ventricular-brain ratio (VBR) in functional psychoses: the relationship of lateral ventricular and total intracranial area.
    Author: Harvey I, Williams M, Toone BK, Lewis SW, Turner SW, McGuffin P.
    Journal: Psychol Med; 1990 Feb; 20(1):55-62. PubMed ID: 2320698.
    Abstract:
    CT scans were performed on 72 consecutive patients with a functional psychosis, and compared with 50 community controls. There was a specific difference in lateral ventricular area between these two groups but it accounted for only 11% of the variance in this measure. In contrast, racial and sexual differences in the ventricular-brain ratio (VBR) related to differences in intracranial area. It is argued that analysis of variance, using lateral ventricular area and intra-cranial area, is more informative than VBR in examining these structural changes in functional psychoses.
