BPPV is the best understood form of vertigo, and usually goes away promptly with simple maneuvers. Sometimes, though, it can persist, and in those cases, a somewhat different and rare form is diagnosed, called cupulolithiasis.

In the time before we knew that ear stones—otoconia—moved freely in the ear canals causing vertigo, there was a theory that all the symptoms of BPPV were caused by otoconia that were attached to the sensor itself. Does this really happen?
