Relationship between Laterality of Auditory Brainstem Response and Speech Comprehension in Children with Autism Spectrum Disorders : A Preliminary Retrospective Controlled Study / 中山大学学报(医学科学版)

ABSTRACT

[Objective] To explore the relationship between laterality of auditory brainstem response and speech comprehension in children with autism spectrum disorders preliminarily.[Method] Review hearing diagnosis data in clinical audiology center from September 2013 to August 2015.We compare auditory brainstem responses in children with autism spectrum disorders (ASD group) and with other disorders (control group),and we further divide children with autism spectrum disorders into two groups (high ability group and low ability group) in terms of their speech comprehension and compare their auditory brainstem responses.[Result] The latencies of waves Ⅲ and Ⅴ,and interpeak latencies Ⅰ to Ⅲ and Ⅰ to Ⅴ of the ASD were significantly prolonged than the control group.And the laterality of waves Ⅲ and Ⅴ,and interpeak latencies Ⅰ to Ⅲ and Ⅰ to Ⅴ present in the ASD group,but not in the control group.Meanwhile,the laterality of waves Ⅲ and Ⅴ,and interpeak latencies Ⅰ to Ⅲ and Ⅰ to Ⅴ present in the high ability group,but not in the low ability group.[Conclusion] Laterality was not a common phenomenon in auditory brainstem response,and it may be associated with the development of speech comprehension in children with autism spectrum disorders.
