Introduction and Case Presentation: Brain death can be associated with limb movements that are attributed to spinal reflexes. Although head/face movements have been rarely reported, no case of overt eye movements in brain death has been documented. We report a case of a patient with subtle eye movements whose exam was otherwise consistent with brain death. The presence of eye movements delayed pronouncing the patient as brain dead and delayed organ donation. We agree with American Academy of Neurology Position statement from 2019 that brain death does not mean demise of every neuron. Discussion: This case raises important questions about the types of movements that should be "allowed" during the determination of brain death to avoid delays in diagnosis.
脑死亡可能与被归因于脊髓反射的肢体运动相关。虽然头部/面部运动很少有报道，但脑死亡患者没有明显的眼球运动病例被记录。我们报告了一例患者存在轻微的眼球运动，而其检查结果与脑死亡一致。眼球运动的存在延迟了宣告患者脑死亡的时间，并延迟了器官捐献。我们同意美国神经病学学会 2019 年的立场声明，即脑死亡并不意味着每个神经元的死亡。讨论：该病例提出了一些重要的问题，即关于在确定脑死亡时应该“允许”的运动类型，以避免诊断延迟。
