【目的】探讨孤独症谱系障碍和发育性语言延迟儿童的听觉诱发电位特征,为观察两者听觉诱发电位的差异和制定个体语言干预方案提供依据。【方法】对20例孤独症谱系障碍和20例发育性语言延迟儿童进行听觉诱发电位测试,分析各波潜伏期及波间期,并与正常组比较。【结果】孤独症谱系障碍组和发育性语言延迟组分别与正常组比较,III、V波潜伏期和I-III波、I-V波潜伏期均显著延长(P<0.01),而两病例组间差异无统计学意义(P>0.05)。【结论】孤独症谱系障碍和发育性语言延迟儿童可能具有共同的听觉处理缺陷。
【Objective】 To investigate the characteristics of auditory evoked potentials in children with autism spectrum disorder and developmental language delay, and to provide basis for observing the difference of auditory evoked potentials and formulating individual language intervention programs. 【Methods】 Auditory evoked potentials were measured in 20 children with autism spectrum disorder and 20 children with developmental delay. The latency and wave interval of each wave were analyzed and compared with the normal group. 【Results】 Compared with the normal group, the latent period of III and V wave and the latencies of I-III wave and IV wave were significantly prolonged in autistic spectrum disorder group and developmental language delayed group, respectively (P <0.01). However, there was no significant difference between the two groups Statistical significance (P> 0.05). 【Conclusion】 Children with autism spectrum disorder and developmental language delay may have common defects in auditory processing.
