“…When researching the cognitive potentials, mean P3 latency values of 318.1 ms for the right ear and 331.9 ms for the left ear were observed in the SG with the toneburst stimulus (Table 3). These values are lower than those from another study 8 , which presented a mean P3 latency value of 369.7 ms, and yet another 9 , with mean P3 latency value of 383.1 ms. In this study, latency was higher for the left ear, which agrees with another study 23 , in which worse P3 latency and amplitude results were observed, always for the left ear, in aphasic individuals with left hemisphere injury caused by a stroke.…”

ABSTRACT Purpose: to verify the functioning of the outer hair cells and the medial efferent olivocochlear system, and the integrity of the auditory pathways in the brainstem up to the auditory cortex, in aphasic individuals. Methods: the sample comprised 20 individuals - 10 without aphasia and 10 with it, aged from 21 to 58 years. The procedures used were the research of the otoacoustic emissions by a transient stimulus with and without noise, and the cognitive potential (tone-burst and speech stimuli). The findings were analyzed based on descriptive statistics. Results: the suppression effect was more present in individuals without aphasia when compared with the aphasic ones. In the cognitive potential, the mean latency values of P3 was within normality standards, with a higher latency in the individuals presented with aphasia for the tone-burst stimulus in both ears. A statistically significant difference of the P3-N2 amplitude was observed for the tone-burst stimulus, comparing the ears in both groups, and for speech stimulus only to the left ear in both groups. Conclusions: aphasic individuals did not present significant differences regarding suppression of the otoacoustic emissions. As for the cognitive potential, the aphasic individuals presented higher latency values when compared to those with no aphasia.

“…As for LLAEP, studies have shown that aphasics have greater P300 wave latency in the left ear of individuals with left hemisphere damage caused by a stroke. This suggests that absent or abnormal P300 responses may be related to linguistic changes, corroborating the sensory and cognitive difficulties in processing message decoding 29,30 .…”

“…Concordantly, studies 22,[28][29][30] in aphasic populations demonstrated increased latency or absent waves. The increase in latencies was related to the difficulty that aphasic individuals tend to have in situations involving auditory discrimination, memory, and attention mechanisms.…”

Purpose: to report scientific evidence on the impact of aphasia on central auditory processing and map the contribution of auditory training to aphasic individuals. Methods: a scoping review approaching national and international databases (SciELO, LILACS, PubMed, Scopus, and Cochrane Library) and the gray literature (Google Scholar and Open Grey). The inclusion criteria covered articles that addressed the interface between central auditory processing and aphasia, excluding duplicates, literature reviews, and scientific abstracts. Literature Review: the review comprised 13 articles that met the eligibility criteria for this study. Seven of the selected articles assessed central auditory processing, four used electrophysiological examinations (such as auditory brainstem response and long-latency auditory evoked potentials) to assess the auditory pathway, and only one analyzed the intervention in aphasic individuals with auditory training. Conclusion: scientific evidence points to an important change in aphasic people’s central auditory processing, with impaired figure-ground, auditory closure, temporal resolution and ordering, and binaural integration. Moreover, it is relevant to assess auditory processing, given the contribution of auditory training in speech-language-hearing therapy for a better prognosis in the rehabilitation of aphasia.

“…No exame PEALL, as pesquisas têm demonstrado que os afásicos apresentam latência da onda P300 maior para a orelha esquerda em indivíduos com lesão no hemisfério esquerdo causada pelo acidente vascular cerebral (AVC), o que sugere que a ausência ou alteração da resposta P300 pode estar relacionada à alteração linguística, corroborando as dificuldades no processamento de decodificação de mensagens a nível sensorial e cognitivo 29,30 .…”

Section: Revisão Da Literaturaunclassified

“…Em conformidade, estudos 22,[28][29][30] realizados com população afásica demonstraram latência aumentada ou ausência das ondas. O aumento das latências foi relacionado à dificuldade que indivíduos afásicos tendem a apresentar em situações que envolvem mecanismos de discriminação auditiva, memória e atenção.…”

RESUMO Objetivo: reportar as evidências científicas do impacto da afasia no Processamento Auditivo Central e mapear a contribuição do Treinamento Auditivo para a população afásica. Métodos: trata-se de uma revisão de escopo realizada nas bases de dados nacionais e internacionais: Scielo, Lilacs, Pubmed, Scopus, Cochrane Library e com uma busca adicional à literatura cinzenta no Google Scholar e Open Grey. Os critérios de inclusão abrangeram artigos que abordassem a interface do processamento auditivo central e afasia, excluindo-se as duplicações, artigos de revisão da literatura e resumos científicos. Revisão de Literatura: selecionaram-se 13 artigos que cumpriram os critérios de elegibilidade deste estudo. Dos artigos selecionados, sete apresentaram a avaliação do Processamento Auditivo Central, quatro apresentaram os exames eletrofisiológicos - como os exames de Potencial Evocado Auditivo de Tronco Encefálico (PEATE) e Potencial Evocado Auditivo de Longa Latência (PEALL) - para avaliação da via auditiva e apenas um estudo analisou a intervenção dos indivíduos afásicos por meio do treinamento auditivo. Conclusão: as evidências científicas apontam importante alteração no Processamento Auditivo Central dos afásicos, apresentando prejuízos nas habilidades auditivas de figura-fundo, fechamento auditivo, resolução e ordenação temporal e integração binaural. Ainda, demonstra-se como relevante a avaliação do processamento, devido à contribuição do Treinamento Auditivo nas terapias fonoaudiológicas para um melhor prognóstico na reabilitação das afasias.
