RESUMO
OBJECTIVE: Describe findings observed in ENG of patients with spinocerebellar ataxias. METHOD: Forty-three patients were studied, and the following procedures were carried out: anamnesis, otorhinolaryngological and vestibular evaluation (ENG). RESULTS: The clinical findings in the entire group of patients were: gait disturbances (83.72%), speech difficulties (48.83%), dizziness (41.86%) and dysphagia (39.53%). Vestibular examination disclosed abnormal caloric exam (83.71%) and saccadic movements (69.76%) with the highest rates of abnormality. The overall presence of alterations in vestibular tests was (90.70%), and the most frequent finding was central vestibular disorder in (74.42%) of patients. CONCLUSION: The study showed that alterations in ENG are related to the severity of SCAs or clinical stage of the disease. We emphasize the importance of studying the vestibular system concomitantly to clinical and genetic follow up.

Our objective was to describe vestibular abnormalities in patients with relapsing and remitting multiple sclerosis. Thirty patients (6 men and 24 women) between 27 and 64 years of age underwent neurological and otolaryngological examinations, complete anamnesis, and electronystagmography. Patients with psychological or oculomotor paresis (or both), internuclear ophthalmoparesis, severe visual disturbances, or locomotion restrictions were excluded. The difference-of-proportion test was used to compare affected patients with controls, with a significance level of 5%. Vestibular alterations were found in 26 (86%) of the evaluated patients, from which 25 presented peripheral etiology and only 1 presented a problem of central origin. There was a prevalence of bilateral peripheral irritative vestibulopathy (20%), followed by bilateral peripheral deficit vestibulopathy (20%) and left peripheral deficit vestibulopathy (17%). The high incidence of vestibular disorders observed in this study indicates that this population might benefit from specific rehabilitation programs. Studies with larger samples are still required and may contribute to the understanding of this pathology.
