We studied the relationship between vertigo and stress, using an internet survey. A questionnaire posted on our homepage quantified and measured 4 categories: cause of anxiety, behavioral characteristics, mean of relaxation, and frequency of vertigo. There were 6065 responses. Scores for the cause of anxiety were significantly greater and scores of means of relaxation were less in older than younger respondents. Scores for the cause of anxiety and behavioral characteristics were singificantly greater in more frequent than less frequent vertigo. Scores for means of relaxation were less in frequent vertigo. These findings indicate an intimate relationship between the onset of vestibular disorder and stress.
