Sensory symptoms, including auditory processing deficits, are common in autism spectrum disorder (ASD). Processing of temporal aspects of auditory input is understudied; yet, deficits in this domain could contribute to language-related impairments. In children with ASD and well-matched controls, this study examined electrophysiological response to silent gaps in auditory stimuli. Results revealed attenuated amplitude of the P2 event-related potential (ERP) component in ASD. The P2 amplitude reduction was also associated with sensory, language, and diagnostic features. These results suggest that neural response during auditory gap detection is a promising ASD biomarker that could be useful for stratifying subgroups and evaluating treatment response.
感觉症状,包括听觉处理缺陷,在自闭症谱系障碍(ASD)中很常见。对听觉输入的时间方面的处理研究较少;然而,这一领域的缺陷可能导致与语言相关的障碍。在患有ASD的儿童和匹配良好的对照组中,本研究检测了对听觉刺激中无声间隙的电生理反应。结果显示,ASD患者P2事件相关电位(ERP)成分的振幅减弱。P2振幅降低还与感觉、语言和诊断特征相关。这些结果表明,听觉间隙检测期间的神经反应是一种很有前景的ASD生物标志物,可用于对亚组进行分层和评估治疗反应。
