在以前的报告中，我们已经提出，成年唐氏综合征的听觉脑干反应（ABR）表现出两个独特的人口异常：缩短中枢传导时间和刺激率增加的不敏感性的峰值潜伏期。目前的实验评估了这些异常是由听力缺陷而不是中枢听觉功能障碍引起的可能性。一组成年唐氏综合征患者的ABR与一组非唐氏弱智者和一组非弱智成人对照组进行了比较。听力检查包括纯音听力图，鼓室导抗，和声反射给予所有的弱智受试者。唐氏综合征组中严重听力障碍的发生率为73%，而非唐氏迟缓组为22%。无论听力状况如何，Down组的中枢传导时间均短于其他两组。然而，对刺激率的异常反应被发现反映了高频听力损失，而不是中枢听觉功能障碍。这些数据表明，电池的客观测试，包括鼓室导抗，声反射，并选择ABR的措施可能是有用的，在识别听力障碍唐氏综合征和非唐氏发育迟缓的个人。
In previous reports we have suggested that the auditory brain-stem responses (ABRs) of adults with Down's syndrome exhibit two abnormalities unique to that population: a shortened central conduction time and an insensitivity of peak latencies to increases in stimulation rate. The current experiment assessed the possibility that these abnormalities were caused by hearing deficit rather than central auditory dysfunction. The ABRs of a group of adults with Down's syndrome were compared with those of a group of non-Down retarded and a control group of nonretarded adults. An audiometric examination consisting of pure-tone audiograms, tympanometry, and acoustic reflexes was given to all the retarded subjects. The incidence of serious hearing deficit in the Down's syndrome group was 73% compared to 22% in the non-Down retarded. Regardless of hearing status, the central conduction times in the Down group were shorter than in either of the other groups. The abnormal response to stimulation rate, however, was found to reflect high-frequency hearing loss and not central auditory dysfunction. The data suggest that a battery of objective tests including tympanometry, acoustic reflexes, and selected ABR measures may be useful in identifying hearing deficit in both Down-syndrome and non-Down retarded individuals.
