Abstract: Objective: To investigate cortical auditory evoked potentials (CAEPs) in pediatric hearing aid (HA) users, with and without language impairment.<br />Design: 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.<br />Results: 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.<br />Conclusion: Results suggest that abnormal temporal brain function may underlie language impairment in pediatric HA users with moderate sensorineural HL.
