To investigate cortical auditory evoked potentials (CAEPs) in pediatric hearing aid (HA) users, with and without language impairment.
CAEPs were measured in 11 pediatric HA users (age: 8-12 years) with moderate bilateral sensorineural hearing loss (HL); participants were classified according to language ability. CAEPs were also measured for a control group of 11 age-matched, normal-hearing (NH) children.
HL children without language impairment exhibited normal CAEPs. HL children with language impairment exhibited atypical temporal CAEPs, characterized by the absence of N1c; frontocentral responses displayed normal age-related patterns.
Results suggest that abnormal temporal brain function may underlie language impairment in pediatric HA users with moderate sensorineural HL.
研究有或无语言障碍的小儿助听器(HA)使用者的皮质听觉诱发电位(CAEP)。
对11名患有中度双侧感音神经性听力损失(HL)的小儿HA使用者(年龄8至12岁)测量CAEP;参与者根据语言能力进行分类。还对11名年龄匹配的听力正常(NH)儿童组成的对照组测量了CAEP。
无语言障碍的HL儿童表现出正常的CAEP。有语言障碍的HL儿童表现出非典型的颞叶CAEP,其特征为无N1c;额中央反应显示出与年龄相关的正常模式。
结果表明,异常的颞叶脑功能可能是中度感音神经性HL的小儿HA使用者语言障碍的基础。
