[A study of the predispositions of vertiginous patients--psychological states and courses of vertigo and equilibrium disorders].

A questionnaire was mailed to 120 vertiginous patients who had taken either the CMI or the Y-G psychological test over one year ago. Of the 120 patients, 106 answered the questionnaire. They were classified into two groups of emotional instability, group A and group B, according to the results of the test. The subjective improvement rate of group A was 71.9 percent, worse than that of group B. This shows that the patients in group A displayed a tendency to continuously being receive stronger treatment than those in group B. The subjective improvement rate of group B was 90.5 percent, and better than that of group A. But the patients in group B showed no tendency toward vertigo attacks that were milder than those of the patients in group A. Therefore the patients in group B were satisfied by the decrease of the frequency of vertigo attacks. The results suggest that it is highly important to consider the psychological aspects of the patients in group A.
