We routinely use the Cornell Medical Index (CMI) for vertiginous patients. The vertigo of the patients of types III and IV of CMI seemed to be caused by psychological problems and not by organic disease. The Manifest Anxiety Scale (MAS) and the Rosenzweig Picture Frustration Study (P-F Study) were used to analyse the vertigo of these patients in detail. These patients showed strong anxiety tendencies and lack of self-assertion. Thus, vertigo in these psychosomatic patients seemed to be caused by psychic unsteadiness due to lack of self-control.
