Abstract

It is generally accepted that positional vertigo might result both from lesions in the central nervous system and from lesions in the peripheral vestibular organ. In 1921, Bárány described a characteristic paroxysmal vertigo and nystagmus occurring in a certain critical position, and he suggested pathogenesis of this condition attributing to otolith disease. In 1952, Dix and Hallpike described positional vertigo of the benign paroxysmal type (BPPN) due to a disorder of the otolith.
