Central auditory processing outcome after stroke in children

Abstract

Objective: To investigate central auditory processing in children with unilateral stroke and to verify whether the hemisphere affected by the lesion influenced auditory competence. Method: 23 children (13 male) between 7 and 16 years old were evaluated through speech-in-noise tests (auditory closure); dichotic digit test and staggered spondaic word test (selective attention); pitch pattern and duration pattern sequence tests (temporal processing) and their results were compared with control children. Auditory competence was established according to the performance in auditory analysis ability. Results: Was verified similar performance between groups in auditory closure ability and pronounced deficits in selective attention and temporal processing abilities. Most children with stroke showed an impaired auditory ability in a moderate degree. Conclusion: Children with stroke showed deficits in auditory processing and the degree of impairment was not related to the hemisphere affected by the lesion.Keywords: auditory perception, childhood, stroke. RESUMOObjetivo: Investigar as habilidades de processamento auditivo central em crianças com acidente vascular cerebral (AVC) unilateral e verificar se o hemisfério cerebral afetado influiu na competência auditiva. Método: 23 crianças (13 meninos) entre 7 e 16 anos foram avaliados através dos testes de fala com ruído (fechamento auditivo); dicótico de dígitos e de dissílabos alternados (atenção seletiva); padrão temporal de frequência e duração (processamento temporal) e seus resultados comparados aos de crianças controles. A competência auditiva foi estabelecida segundo o desempenho na habilidade de análise auditiva. Resultados: Foi constatado desempenho similar entre os grupos na habilidade de fechamento auditivo e défices acentuados nas habilidades de atenção seletiva e processamento temporal. A maioria das crianças com AVC apresentou comprometimento da habilidade auditiva em grau moderado. Conclusão: Crianças com AVC apresentaram alterações do processamento auditivo e o grau do comprometimento não se relacionou com o hemisfério afetado pela lesão.Palavras-chave: percepção auditiva, infância, acidente vascular cerebral.Childhood stroke were long considered rare and benign. However, 10 to 25% of the affected children die; among survivors, 25% show recurrence that is closely related to the worsening in the prognosis and, 66% have neurological, cognitive, behavioral or, learning problems

Avaliação do processamento auditivo central em crianças e adolescentes acometidos por acidente vascular cerebral: revisão sistemática da literatura

“…When the first three selected descriptors were inserted in each database for the present study, there was a total of 15 studies (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) . One study (8) was excluded because it was repeated in the search in PubMed, hence there were 14 studies left. None of these studies used long-latency auditory evoked potentials for evaluation in children or adolescents affected by stroke.…”

“…Three papers (8)(9)(10) were selected in the first search and one paper (22) in the second. All the studies that evaluated children diagnosed with stroke were read in full.…”

“…All the studies that evaluated children diagnosed with stroke were read in full. Thus, only four papers were left (8)(9)(10)22) : three (8)(9)(10) from the Scopus database and one from the Scopus database in the second search (22) . Notably, no article was found in the SciELO database.…”

“…The studies included in this review (8)(9)(10)22) assessed auditory processing in various ways: two studies (8.9) used Speech-in-noise Tests (SiN), the dichotic digits test (DD), the Staggered Spondaic Word test (SSW), pitch pattern sequence (PPS) and duration pattern sequence (DPS); another study (10) used sub-tests of the Test of Attentional Performance (TAP) and the Test of Attentional Performance for Children (KITAP) associated with a questionnaire to parents, namely, the Child Behavior Checklist (CBL 4-18) (10) ; another study (22) used event-related functional magnetic resonance imaging (fRMI). All selected papers had been written in English, between 2008 and 2014; two studies were conducted in Brazil , (8.9) , one in Germany (10) and one in the United States (22).…”
