The authors undertook in Tunisia a cochleo-vestibular study of multiple sclerosis. 94 cases were included, with the following results:--67 patients had spontaneous nystagmus in the dark.--With provocation studies: - 52 cases showed signs of an irritative-type central vestibular syndrome, - 25 cases had a deficiency-type central vestibular syndrome. All of the patients underwent audition studies but the results showed that only 5 patients had a bilateral and symetrical retro-labyrinthine type perception deafness.
