ABSTRACT

OBJECTIVE:

To describe the alterations observed in electronystagmography (ENG) of patients with spinocerebellar ataxia (SCA) types 2 and 3.

METHOD:

Sixteen patients were studied and the following procedures were carried out anamnesis, otorhinolaryngological and vestibular evaluations.

RESULTS:

The clinical findings in the entire group of patients were gait disturbances (93.75 percent), dysarthria (43.75 percent), headache (43.75 percent), dizziness (37.50 percent) and dysphagia (37.50 percent). In the vestibular exam, the rotatory (62.50 percent) and caloric (75 percent) tests were among those which presented the largest indexes of abnormalities; the presence of alterations in the exams was 87.50 percent, with a predominance of central vestibular disorders in 68.75 percent of the exams.

CONCLUSION:

Vestibular exams could be an auxiliary tool to investigate SCAs, besides a precise clinical approach and, particularly, molecular genetic tests.
RESUMO

OBJETIVO:

Verificar as alterações do exame de eletronistagmografia (ENG) em pacientes com ataxia espinocerebelar (AEC) tipos 2 e 3.

MÉTODO:

16 pacientes foram estudados, com a utilização dos seguintes procedimentos anamnese, avaliação otorrinolaringológica e avaliação vestibular.

RESULTADOS:

As principais queixas encontradas na anamnese foram, desequilíbrio na marcha (93,75 por cento), dificuldades da fala (43,75 por cento), cefaleia (43,75 por cento), tontura (37,50 por cento) e disfagia (37,50 por cento). No exame vestibular, o teste rotatório e o teste calórico apresentaram os maiores índices de anormalidades, respectivamente, 62,50 por cento e 75 por cento, com a predominância de distúrbio vestibular do tipo central em 68,75 por cento dos casos.

CONCLUSÃO:

O exame vestibular pode ser um exame auxiliar na investigação das AECs, junto com a avaliação clínica precisa e, particularmente, com os testes de genética molecular.
