[Video-nystagmography findings in healthy elderly subjects]. / Resultados videonistagmográficos en un grupo de sujetos sanos de edad avanzada.

ABSTRACT

This study investigated 44 healthy elderly subjects aged between 64 and 87, who were analysed with videonystagmoscopy and quantitative videonystagmography, for establishing new standards for normal limits into this new diagnostic tool. 15.9% of the subjects were found to have spontaneous and provoked nystagmus at least in one position studied. Vertical nystagmus in head hanging position was the most frequent finding. In the Dix-Hallpike test we found one case of torsional nystagmus. No subject had seated position nystagmus. Nystagmus after head shaking and evoked nystagmus were not found.
