Stroke caused auditory attention deficits in children

Abstract

OBJECTIVE: To verify the auditory selective attention in children with stroke. METHODS: Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging. RESULTS: The attention performance showed significant differences in comparison to the control group in both kinds of tests. In the non-verbal test, identifications the ear opposite the lesion in the free recall stage was diminished and, in the following stages, a difficulty in directing attention was detected. In the consonant- vowel test, a modification in perceptual asymmetry and difficulty in focusing in the attended stages was found. In the digits and SSW tests, ipsilateral, contralateral and bilateral deficits were detected, depending on the characteristics of the lesions and demand of the task. CONCLUSION: Stroke caused auditory attention deficits when dealing with simultaneous sources of auditory information.

Central auditory processing outcome after stroke in children

“…In this test, as it is a dichotic presentation and it uses verbal stimuli, it would be expected a greater number of errors with the ear contralateral to the lesion or deficits in both ears when the lesion involved only the left hemisphere, as observed in adults 14,16,17 . In our study, this pattern was predominant, but we also observed ipsilateral deficits both in right and left hemisphere lesions, similar in Isaacs et al 18 and a previous study by Elias and Moura-Ribeiro 7 . In both studies, the diversity of the results was related to the variables of the lesion, while Isaacs et 18 consider in particular, the presence of epilepsy.…”

“…Regarding auditory function, there are few studies involving childhood stroke in complete contrast to the relevance that this function assumes for the language and for learning. In this research area, Elias and Moura-Ribeiro 7 found deficits in auditory selective attention in stroke children. Another study, involving neonatal stroke, revealed difficulty of comprehension, which refers to the in-depth evaluation of the auditory function 8 .…”

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.…”

“…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.…”

Fatores na infância e adolescência que podem influenciar o processamento auditivo: revisão sistemática

“…The auditory attention was evaluated by the binaural separation, NVD and consonant-vowel tests, and also by the integration, SSW and dichotic listening tests, being possible the verification of the relationship between the CVA and the deficit in selective attention in both tasks with verbal and non-verbal stimuli 18 . The Auditory Processing Disorder can also be influenced by structural and/or functional alterations in childhood, such as Cleft Lip and Palate, Oral Breathing, Dysphonia and Visual impairment, according to the studies indicated in Figure 4.…”
