孤独症谱系障碍和发育性语言延迟儿童的听觉处理特征研究

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。

Study on central auditory processing characteristics in autism spectrum disorder and developmental language delayed children

Objective To investigate and characterize the relationship of brainstem auditory evoked potential changes between the autism spectrum disorder (ASD) and the developmental language delayed (DLD) disorder in young children. Methods Absolute latencies of waves I,III,V,and interpeak latencies(IPLs)of I to III,I to V,and III to V in Brainstem Auditory Evoked Potentials(BAEP)in the ASD group and the DLD group were compared.Either group enrolled 20 children. Results In comparison with normal children,IPLs of I to III and I to V in both ASD group and DLD group were significantly prolonged.However,there were no significant differences between two groups. Conclusion These two disorders might share the same pathological mechanism in the auditory disorder.
