Brain-stem auditory evoked response (BAER) studies were performed one to 16 days after a vertebrobasilar transient ischemic attack (VB TIA) in eight patients and repeated two to 16 days later in six of them. Initially, all showed absence of waveforms, prolonged interpeak latencies, and/or amplitude reduction. Five of six patients showed reversal of BAER changes to normal; the remaining patient returned to near normal. Normalization occurred six to 24 days after the VB TIA. These results are different from those reported in other studies. Early sequential BAER studies may be helpful in differentiating VB TIA from brain-stem infarction and syndromes that mimic VB TIA.
对8例椎基底动脉短暂性脑缺血发作（VB TIA）患者在发作后1至16天进行了脑干听觉诱发电位（BAER）研究，其中6例在2至16天后进行了重复检查。最初，所有患者均表现为波形缺失、峰间期延长和/或波幅降低。6例患者中有5例BAER变化恢复正常；其余1例患者恢复至接近正常。BAER在VB TIA后6至24天恢复正常。这些结果与其他研究报告的结果不同。早期连续进行BAER研究可能有助于鉴别VB TIA与脑干梗死以及模拟VB TIA的综合征。
