Avaliação de dois testes auditivos centrais em idosos sem queixas Assessment of two central auditory tests in elderly patients without hearing complaints

Abstract

Na população idosa, distúrbios da inteligibilidade de fala podem ter causas periféricas ou centrais. A assimetria em testes dicóticos verbais aumenta com a idade e reflete falha na transferência inter-hemisférica e nas funções cognitivas. OBJETIVO: Investigar o desempenho de idosos, sem queixas auditivas, em dois testes de processamento auditivo. FORMA DO ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Foram avaliados 22 voluntários, com idades entre 55 e 75 anos, com limiares auditivos máximos de 40 dB NA até 4000Hz, índice de reconhecimento de fala acima de 80% e audição simétrica bilateralmente. Aplicaram-se testes de fala com ruído e dicótico de dissílabos alternados (SSW). A análise dos dados comparou gênero, orelhas e grupos etários. RESULTADOS: Não houve diferença entre os gêneros para nenhum dos testes. A orelha esquerda teve desempenho inferior à orelha direita na condição competitiva do teste SSW. Os participantes com idade acima de 65 anos apresentaram desempenho pior em ambos os testes quando comparados com indivíduos de 55 a 64 anos. CONCLUSÃO: O desempenho dos testes auditivos centrais piora com a idade. A introdução de testes dicóticos na bateria de avaliação auditiva de idosos pode contribuir para a identificação precoce de processos degenerativos característicos do envelhecimento.Speech understanding disorders in the elderly may be due to peripheral or central auditory dysfunctions. Asymmetry of results in dichotic testing increases with age, and may reflect on a lack of inter-hemisphere transmission and cognitive decline. AIM: To investigate auditory processing of aged people with no hearing complaints. STUDY DESIGN: clinical prospective. MATERIALS AND METHODS: Twenty-two voluntary individuals, aged between 55 and 75 years, were evaluated. They reported no hearing complaints and had maximal auditory thresholds of 40 dB HL until 4 KHz, 80% of minimal speech recognition scores and peripheral symmetry between the ears. We used two kinds of tests: speech in noise and dichotic alternated dissyllables (SSW). Results were compared between males and females, right and left ears and between age groups. RESULTS: There were no significant differences between genders, in both tests. Their Left ears showed worse results, in the competitive condition of SSW. Individuals aged 65 or older had poorer performances than those aged 55 to 64. CONCLUSION: Central auditory tests showed worse performance with aging. The employment of a dichotic test in the auditory evaluation setting in the elderly may help in the early identification of degenerative processes, which are common among these patients.
