Abstract
Although alcohol is known to affect the vestibules system through the development of a positional alcohol nystagmus, information concerning the effects of alcohol on "vertigo" and nystagmus from stimulation of the semicircular canals is contradictory. Several investigators have reported that alcohol enhances these responses, while others have reported suppressive effects. This study was designed to investigate the effect of alcohol ingestion on both "vertigo" and nystagmic responses to angular stimulation. Responses were obtained (a) with and without visual fixation, and (b) with the alertness of the subjects controlled.
