Aplicabilidade do Mismatch Negativity na população infantil: revisão sistemática de literatura

Abstract

Introduction: Mismatch Negativity (MMN) is an electrophysiological potential that evaluates the brain's capacity to discriminate sounds, regardless of attentional and behavioral capacity. Because it is an objective and user-friendly measure, it becomes promising in the study of auditory processing research in children. Purpose: To verify the applicability of Mismatch Negativity (MMN) in children. Research strategy: A search was conducted in August and September 2016 using the descriptors Evoked Potentials, Auditory AND Children, Eventrelated Potential AND Children and Electrophysiology AND Children in bibliographic collection of the electronic databases Portal BVS (Medline, IBECS and LILACS) and SciELO. Selection criteria: The selection of articles was carried out in Portuguese, English and Spanish published up to September 2016 without initial date limitation and whose approach to Mismatch Negativity was with the child population. Results: The search strategy resulted in the selection of 23 articles classified as original articles. The studies evidenced several applications of MMN in children, including autism spectrum disorder, auditory processing disorders, cleft lip and palate, prematurity, and language-specific disorder, being the majority of them in dyslexia. Conclusion: Despite the great variability involved in the measures of MMN, there is a wide clinical applicability of this electrophysiological potential in the infant population.

Treinamento musical e habilidades do processamento auditivo em crianças: revisão sistemática

“…Another procedure was MMN, which investigates the abilities of sound discrimination, auditory memory and involuntary attention, because it is a long-latency auditory evoked potential that captures automatic brain response (30) . One study reported an improvement in MMN in children aged 8 and 10 years old (8) , while no significant changes were found in another study with children aged between 4 and 6 years old (17) .…”

Mismatch Negativity in Children and Adolescents with Autism Spectrum Disorder

“…In addition, the authors found that most studies in the literature present the comparison of results between the study group and control group. 34 In the present study, there was a predominance of male subjects, which shows weak gender parity. It is known that there is a higher prevalence of ASD in males worldwide, with 4 to 5 times more cases than females.…”

Potencial Evocado Auditivo Mismatch Negativity em músicos e não músicos: Revisão sistematica

“…O Mismatch Negativity (MMN) é um potencial evocado auditivo de longa latência, gerado por meio de respostas eletrofisiológicas que se referem às habilidades de discriminação sonora, processamento auditivo, memória auditiva e atenção involuntária em nível central (Ferreira, Bueno, Costa, & Sleifer, 2017). Tais habilidades cognitivas, características estruturais e encefálicas tem sido alvo de estudos sobre os processos neurais auditivos em pessoas com habilidades auditivas excepcionais, como os músicos, que são expostos à percepção e o processamento da música (Nikjeh, Lister, & Frisch, 2009).…”

“…Segundo (Ferreira et al, 2017), o Mismatch Negativity de forma espontânea demonstra seus resultados em formato de onda com polaridade negativa (negativity), não necessitando da atenção do indivíduo aos estímulos sonoros. A obtenção dos resultados acontece ao subtrair a detecção de sons inesperados (mistmatch), e sons já armazenados na memória sensorial auditiva de curto prazo.…”
