This study evaluated auditory processing in a group of 59 infants at risk for subsequent hearing and language disorders due to low birthweight and/or perinatal asphyxia. Auditory system integrity was evaluated electrophysiologically by recording the auditory brainstem response (ABR), middle latency response (MLR) and the cortical auditory evoked potential (CAEP). 63% of the babies had normal peripheral function or slight unilateral impairment; 84% had normal brainstem auditory system function; 82% showed normal MLRs; and 81% showed normal CAEPs. Fifty-three percent of the babies were normal on all tests and only 3% were deviant on all tests. The remaining infants showed diverse patterns of peripheral, brainstem and cortical abnormalities.
本研究评估了一组59名因低出生体重和/或围产期窒息而有后续听力和语言障碍风险的婴儿的听觉处理能力。通过记录听觉脑干反应（ABR）、中潜伏期反应（MLR）和皮层听觉诱发电位（CAEP），从电生理学角度评估听觉系统的完整性。63%的婴儿外周功能正常或有轻微单侧损伤；84%的婴儿脑干听觉系统功能正常；82%的婴儿中潜伏期反应正常；81%的婴儿皮层听觉诱发电位正常。53%的婴儿所有测试结果均正常，只有3%的婴儿所有测试结果均异常。其余婴儿表现出外周、脑干和皮层异常的不同模式。
