Depersonalization, vertigo and Ménière's disease

Ménière's disease is generally accepted to be a consequence of distention of the endolymphatic sac of the inner ear. Although the exact etiology is unclear, there is a body of research suggesting that Ménière's disease is of psychosomatic origin. While we do not intend to review the literature exhaustively, we briefly review several frequently cited studies. Even though this literature is so severely flawed that no solid conclusions may be drawn from it, certain questions about the psychological aspect of this disorder continue to surface. Our limited access to patients with vertigo has not allowed us to undertake a carefully designed study. However, in clinical practice we have noted that many persons who complain of vertigo (whether due to Ménière's disease or other causes) also report symptoms of depersonalization and derealization. In this paper we present the cases of two women with Ménière's disease who also experienced concurrent feelings of unreality. It appears likely that feelings of unreality may occur regularly in association with syndromes causing vertigo, presumably as a consequence of vestibular dysfunction. We argue that emotional disturbances previously identified as predisposing causes of Ménière's disease are more likely effects of the disease. Although the discussion of two uncontrolled cases can do little to help solve nagging questions about a psychosomatic component to this disorder, we believe it may suggest a different perspective from which to investigate these complex phenomena.
