Meeting: 2018 International Congress

Abstract Number: 613

Keywords: Dysphagia, Episodic ataxia, Spinocerebellar ataxia

Session Information

Date: Sunday, October 7, 2018

Session Title: Ataxia

Session Time: 1:45pm-3:15pm

Location: Hall 3FG

Objective: To describe the audiological and electrophysiological results in patients with sporadic ataxia.

Background: Patients with progressive non-familial adult ataxia are classified into a sporadic ataxia (SA) group. There are several categories of diseases that can manifest with SA due to toxic causes, immune-mediated ataxias, vitamin deficiency, infectious diseases, degenerative disorders and even genetic conditions.

Methods: A retrospective cross-sectional study was conducted. Eleven patients were assessed using the following procedures: anamnesis, otolaryngologic exam, pure tone audiometry, acoustic immittance measures and brainstem auditory evoked potential (BAEP).

Results: a) patients showed gait abnormality (81.8%), dysarthria (63.8%) and dysphagia (54.5%). Hearing loss was referred in 36.3% of the cases; b) audiometric exams were abnormal in four patients (36.4%); c) BAEP were abnormal in four patients (36.4%), 18.2% occurred bilaterally and left ear, respectively; and d) acoustic immittance measurements were abnormal in five patients (45.4%) with predominance of bilaterally.

Conclusions: The most evident abnormalities in the audiological evaluation were the predominance of the down-sloping audiometric configuration beginning at 4 kHz and the bilateral absence of acoustic reflex at the frequencies of 3-4 kHz. In the electrophysiological evaluation the patients showed abnormalities with prevalence of an increase of the latency of waves I, II and V, and of the interval in the interpeaks I-III, I-V and III-V.
