| Resumo: | Introduction: Autistic Spectrum Disorder (ASD) is considered a neurodevelopmental
disorder with high worldwide prevalence and is characterized mainly by deficits in
social skills, social interaction and the possibility of sensory-perceptual changes.
Studies have shown the possibility of hearing hypersensitivity in these individuals, as
well as behaviors that resemble hearing loss. Thus, hearing assessment is an essential
part of the process of diagnosing cases with suspected ASD. Objective: To analyze
the feasibility and results of the behavioral, electroacoustic and electrophysiological
auditory assessment of children with clinical signs of ASD risk, as well as the parents'
perception about the occurrence of hypersensitivity. Method: this is an observational
and cross-sectional study, structured in two studies: (1) audiological behavioral,
electro-acoustic and electrophysiological evaluation of children with clinical signs of
ASD risk: a series of cases and (2) parents' perception of hypersensitivity hearing loss
in children with clinical signs of ASD risk: a preliminary study. Results: Nine children
were evaluated in the first study and all were able to perform behavioral assessment.
Despite the absence of hearing loss, there was a change in electroacoustic and
electrophysiological tests, with absent acoustic reflexes and absolute latencies of
waves III and V and increased interpeak intervals. The complaint of hypersensitivity
was found in 66.6% of the children, with behaviors related to misophonia being
reported. Conclusion: the children with clinical signs of ASD did not present peripheral
hearing loss, however, there was an alteration in the auditory pathway from the
cochlear nuclei and a high occurrence of hearing hypersensitivity complaint in this population. |
