Abstract

Auditory brainstem response (ABR) testing is a well-established diagnostic tool used to assess the integrity and functionality of the auditory pathways from the ear to the brainstem. In recent years, it has garnered attention as a potential diagnostic marker in individuals with Autism Spectrum Disorder (ASD) and delayed speech development. Given the increasing prevalence of ASD globally, the early detection and understanding of its underlying neurophysiological markers are critical. This article delves into the auditory brainstem response results in individuals with ASD, particularly focusing on those who also exhibit delayed speech development, and explores the implications for clinical practice and further research.
