Ménière's disease.

Even more than a century after the first description of Ménière's disease, Portmann (1927) said: 'Ménière's is one of the least understood disorders both by doctors in general and specialists. It is variable in clinical presentation, imprecise in diagnosis, and because the effectiveness of treatment is doubtful, leaves the clinician disillusioned, depriving the patient of the potential cure that has become the rule.'
