Ventricular Enlargement in Adults With Profound Mental Retardation Who Demonstrate Violent/Destructive Behaviors

Published Online:1 Feb 2001

Abstract

The authors determined brain ventricular size (ventricular brain ratio [VBR]) in 39 ambulatory adult mentally retarded individuals who did or did not require psychotropic medication for violent/destructive behavior. The mean VBR of mentally retarded patients who required psychotropic medication was significantly greater than the VBR of those who did not require such medication.
