摘　　要：目的 :观察偏头痛患者发作期脑干听觉诱发电位 (BAEP)和瞬目反射 (BR)改变。方法 :对 4 5例偏头痛发作期患者进行BAEP、BR检测。结果 :BR和BAEP联合检测提示脑干病变者 31例 ,占6 9 % ;BAEP、BR检测提示听神经、三叉神经传入通路功能障碍和面神经传出通路功能障碍共 2 6例 ,占5 8% ,其中三叉神经传入通路障碍 2 1例 ,占 81%。结论 :偏头痛发作期存在着以脑干和三叉神经为主的神经功能障碍 ,与血管舒缩功能障碍很可能互为因果。Objective:To investigate the changes of brainstem auditory evoked potentials(BAEP) and blink reflex(BR) in migraineurs during attack.Methods: BAEP and BR were performed on 45 migraineurs.Results:BAEP and BR Showed brainstem dysfunction in 31(69%) patients and afferent pathway impairment of auditory nerves, trigeminal nerves, and efferent pathway impairment of facial nerves were found in 26(58% of the total cases) cases, in which 21 cases were afferent pathway impairment of trgeminal nerves, accounting for 81%. Conclusion:Migraine attack miyht be characterized by brainstem and trigeminal nerve dysfunction which may interplay with the dysfunction of blood vessels.
