Parents’ perception of auditory hypersensitivity in children with clinical signs of risk for Autism Spectrum Disorder

Abstract

Objective: To investigate the occurrence and type of auditory hypersensitivity in children with clinical signs of Autism Spectrum Disorder through parents' reports in the context of the COVID-19 pandemic. Method: This is a cross-sectional and descriptive study, composed of parents of 11 children with clinical signs of risk for Autism Spectrum Disorder. The children were of both sexes, with a mean age of 44.8 months. Parents answered a previously validated questionnaire about their children's auditory hypersensitivity behaviors by telephone. A score equal to or greater than eight points in the general score was considered as a sign of hypersensitivity. Results: 63.6% of the children presented results indicative of hypersensitivity and 54.5% obtained maximum scores on questions related to irritability to specific sounds. The sounds cited as generating irritability were: clapping, fireworks, shouting, construction tools, singing and cell phone ringtones. Conclusion: Auditory hypersensitivity was observed, especially related to irritability, which suggests a relationship with the limbic system and, therefore, may refer to misophonia. Thus, it is important for the multidisciplinary team to pay attention to the occurrence and characteristics of hypersensitivity in this population, in order to maximize favorable conditions for rehabilitation.
