Avaliação de dois testes auditivos centrais em idosos sem queixas

Abstract: 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 max… Show more

“…Individuals in this age group naturally have more difficulty in recognizing distorted signals and/or amid background noise signals due to changes in information auditory processing 35,36 . The findings of this study comply with the consideration outlined above, since even with the distorted signal, seniors are able to benefit from the increased acoustic information conveyed by the use of CNLF in silence, but this did not occur in noise.…”

“…The effects of aging on asymmetry of auditory center function remain controversial. The findings from a large number of early dichotic listening tests indicate that asymmetry of speech processing increases in elderly people, regardless of hearing loss, and that the main manifestation of this is the left ear disadvantage [11]. In contrast, another study, involving young and elderly subjects who were required to perform competitive verbal tasks, found that asymmetry of the left hemispheric advantage was decreased or even reversed in elderly subjects [12].…”

“…No teste de FRB foi observado que houve diminuição estatisticamente significante da porcentagem de acertos com o aumento da idade (Tabela 7; Figura 4), o que sugere que o envelhecimento provoca um declínio da habilidade de fechamento auditivo, como também observado por Cox et al (2008), Calais et al (2008), Wong et al (2009) e Gonçales & Cury (2011). Os autores relacionam a dificuldade de fala com ruído entre indivíduos idosos à alteração na interação entre regiões corticais cognitivas e sensoriais, ambas em processo progressivo de degeneração causada pelo efeito do tempo sobre o SNC.…”

“…Outro fator que pode ter influenciado no pior desempenho dos participantes mais velhos no teste de FRB, é o aumento da ocorrência de perda auditiva nas frequências de 3 KHz a 8 KHz com o avanço da idade, observado na comparação entre os grupos da presente pesquisa. Este fator corrobora com os achados nas pesquisas de Gonçales & Cury (2011) e Cox et al (2008), que relatam que a perda auditiva periférica é um fator de risco para o mau desempenho em teste de escuta monótica, principalmente quando acomete as frequências de 500 a 4000 Hz, ressaltando a importância de considerar a perda auditiva na avaliação do processamento auditivo (central) de idosos. Os estudos confirmam a hipótese da presente pesquisa de que a perda auditiva pode ter influenciado na diminuição da porcentagem de acertos no teste de FRB com o avanço da idade.…”
