Alterations in early auditory evoked potentials in multiple sclerosis patients
SummaryAlterations in early auditory evoked potentials (EAEP) in individuals with demyelinating disease are suggestive of lesions in the brainstem.Aimthis study aims to evaluate the prevalence of hearing disorders and altered EAEP in multiple sclerosis (MS) patients.Materials and methodsixteen female and nine male patients with a defined diagnosis of multiple sclerosis took part in this study. All individuals underwent hearing and EAEP tests. The wave forms were categorized according to Jerger (1986).Resultsfifty EAEP tests were carried out; 70% were classified as type I (normal response) according to Jerger's criteria. Altered EAEP results in at least one ear were classified into types II, III, IV or V according to Jerger. Females accounted for 31.25% of alterations, and males 44.44%, adding up to 36% of all cases.Conclusionsthese findings stress the importance of looking at EAEP in cases where there is suspicion of demyelinating disease and in patients with a defined diagnosis for MS
Alterações dos potenciais evocados auditivos do tronco encefálico em pacientes com esclerose múltipla Alterations in early auditory evoked potentials in multiple sclerosis patients
A presença de alterações nos potenciais evocados auditivos do tronco encefálico (PEATE) em indivĂduos com doenças desmielinizantes sugere lesĂŁo do tronco encefálico. OBJETIVOS: O objetivo do presente estudo foi avaliar a incidĂŞncia de alterações auditivas e dos PEATE em indivĂduos com esclerose mĂşltipla (EM). MATERIAL E MÉTODO: Participaram do estudo 16 pacientes do sexo feminino e 9 do sexo masculino com diagnĂłstico definido de EM. Testes audiomĂ©tricos e pesquisa dos PEATE foram realizados em todos os indivĂduos. Para a classificação dos PEATE utilizou-se a classificação proposta por Jerger (1986) na análise da morfologia das ondas. FORMA DE ESTUDO: Estudo de coorte contemporânea com corte transversal. RESULTADOS: Dos 50 PEATE realizados, 70% foram classificados como tipo I (resposta normal) pela classificação de Jerger. Considerando-se como alterados os PEATE dos tipos II, III, IV ou V da classificação de Jerger em pelo menos um dos lados, encontrou-se 31,25% de alterações no sexo feminino e 44,44% no masculino, totalizando 36%. CONCLUSĂ•ES: Estes achados enfatizam a relevância do estudo dos PEATE em casos de suspeita clĂnica de doenças desmielinizantes e naqueles com diagnĂłstico definido de EM.<br>Alterations in early auditory evoked potentials (EAEP) in individuals with demyelinating disease are suggestive of lesions in the brainstem.
