“…In a study, the cognitive potential -P300, which is a cognitive auditory potential, showed considerable change, both in latency and amplitude, showing the effect of neuroplasticity after the intervention (29) . When analyzing the effectiveness of auditory training through the P300, the authors found reduced latency and increased P300 amplitude after the intervention, results that are consistent with the findings of the current study.…”

Purpose To analyze the effectiveness of a therapeutic intervention plan through an existing cognitive auditory training program, adapted for adults, after one year of COVID-19 infection. Methods 13 subjects, between 18 and 59 years old, four males and nine females participated in the study. All underwent anamnesis, visual inspection of the external acoustic meatus, pure tone audiometry, speech audiometry and acoustic immitance measurements as selection procedures. For the research, the following procedures were carried out in the evaluation and reassessment: evaluation of central auditory processing, brief neuropsychological evaluation - NEUPSILIN, Speech, Spatial and Qualities of Hearing Scale and the Cognitive Potential - P300 with speech stimulus. Cognitive auditory training was carried out in six consecutive sessions, in an open field, lasting approximately 50 minutes. In all analyses, a significance level of 5% (p≤0.05) was considered. Results When comparing the variables between the periods, pre and post intervention, there was a statistically significant difference in the Dichotic Digit Test (p = 0.009), in the Frequency Pattern Test (p = 0.020) and in Speech, Spatial and Qualities of Hearing Scale (p = 0.001). And a tendency to significance (p < 0.10) in the Gap in Noise test and Total Attention. Conclusion Cognitive auditory training proved to be an effective therapeutic strategy for the treatment of adults with speech comprehension and cognition complaints after COVID-19 infection.

“…Em um estudo, o potencial cognitivo -P300, que é um potencial auditivo cognitivo, apresentou considerável mudança, tanto em latência, quanto em amplitude, demonstrando o efeito da neuroplasticidade após a intervenção (29) . Ao analisarem a efetividade do treinamento auditivo por meio do P300, os autores observaram redução da latência e aumento da amplitude do P300 após a intervenção, resultados condizentes com os achados do atual estudo.…”

RESUMO Objetivo analisar a eficácia de um plano de intervenção terapêutica por meio de um programa de treinamento auditivo cognitivo já existente, adaptado para adultos, após um ano de infecção por COVID-19. Métodos participaram do estudo 13 sujeitos, entre 18 e 59 anos de idade, quatro do gênero masculino e nove do gênero feminino. Todos foram submetidos a um questionário, inspeção visual do meato acústico externo, audiometria tonal liminar, logoaudiometria e medidas de imitância acústica, como procedimentos de seleção. Foram realizados, na avaliação e na reavaliação, os seguintes procedimentos: avaliação do processamento auditivo central, avaliação neuropsicológica breve-NEUPSILIN, Speech, Spatial and Qualities of Hearing Scale e o Potencial Cognitivo - P300, com estímulo de fala. O treinamento auditivo cognitivo foi realizado em seis sessões consecutivas, em campo aberto, com duração de, aproximadamente, 50 minutos. Em todas as análises foi considerado o nível de significância de 5% (p≤0,05). Resultados na comparação das variáveis entre os períodos, pré e pós-intervenção, houve diferença estatisticamente significativa no Teste Dicótico de Dígitos (p = 0,009), no Teste Padrão de Frequência (p = 0,020) e no Speech, Spatial and Qualities of Hearing Scale (p = 0,001). Houve tendência à significância (p < 0,10) no teste Gap in Noise e na Atenção Total. Conclusão o treinamento auditivo cognitivo demonstrou ser uma estratégia terapêutica eficaz para o tratamento de adultos com queixas de compreensão de fala e de cognição após infecção por COVID-19.

“…There are several previous studies in the literature involving the AP and the AEPs, especially regarding the P300 cognitive component. 11,[14][15][16] Additionally, there are studies that sought to investigate the electrophysiological activity of the central auditory pathway in cases of APD, correlating the objective findings with the behavioral ones. 17,18 However, there are no in-depth studies on the accuracy of AEPs in AP alterations in adults, without other associated pathologies.…”

Introduction Auditory evoked potentials are widely used in clinical practice to complement the assessment of central auditory processing. However, it is necessary to understand whether these potentials are highly accurate, to assist in the diagnosis of auditory processing disorder. Objective To measure the accuracy of middle and long latency auditory evoked potentials in the diagnosis of auditory processing disorder in adults. Methods This is a case-control study, formed by a control group of 30 individuals with normal auditory processing assessment, and a case group composed of 43 individuals with altered auditory processing assessment. Their sensitivities, specificities, accuracies, positive and negative predictive values for the diagnosis of alterations were measured and compared between the potentials. Results The accuracies of the middle and long latency potentials were 51% and 67%, respectively. The P1-N1-P2 and N2-P300 complexes had an accuracy of 57.5% and 58.9%, respectively. The cognitive potential P300 showed an accuracy of 55%. There was no significant result for the middle-latency potential (OR = 1.8; 95% CI: 0.6–5.4, p > 0.42) and for P300 (OR = 2.63, 95% CI: 0.85–8.43, p > 0.11). However, the result was significant for the long-latency potential (OR = 6.3; 95% CI: 2–19.6, p < 0.01). There was a significant result for the P1-N1-P2 complexes (OR = 6.76, 95% CI:1.4–32.5, p = < 0.010) and N2-P300 (OR = 3.60; 95% CI: 10.16–11.20, p < 0.039). Conclusion Individuals with altered long-latency auditory evoked potential are more likely to have auditory processing disorder and, as such, this test can be used as a complementary tool to confirm the diagnosis.
