![]() Children with absent responses persisted to have absent responses. At 6-month evaluation, the P1-CAEP latencies improved equally in the ANSD and SNHL groups. The latency of P1 was prolonged in both groups compared with the normal hearing loss group. Only one child from the SNHL group did not show P1-CAEP responses to the ‘da’ stimulus. In the initial evaluation, 80% of ANSD children showed P1 response to the ‘ba’ stimulus and 87% of children to the ‘da’ stimulus. The P1-CAEPs were elicited using the temporally modified synthetic ‘ba’ and ‘da’ syllables. Verification of hearing aids was carried out twice with 6 months of interval and included evaluation of aided sound field and P1-CAEP, and evaluation using the Arabic version of the Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS). The SNHL group was closely matched to the ANSD group. ![]() The ANSD group had a mean age of 48.2 (☒9.4) months and included children with moderate-to-severe hearing loss, a history of bilateral hearing aid use for at least 6 months, and absence of comorbid disorders. Study designįorty-five children were divided into three groups: the ANSD group ( n=15), the sensorineural hearing loss (SNHL) group ( n=15), and the normal hearing group ( n=15). The aim of this study was to explore the outcome of hearing aid amplification in children with auditory neuropathy spectrum disorder (ANSD) using speech P1 cortical auditory evoked potential (P1-CAEP).
