Two cases of brain stem stroke involving the upper pons and the ponto-mesencephalic junction presented with transient excessive pathological yawning, associated with gait ataxia and in one subject with upper limb and facial hemiparesis. A causal relation is hypothesised between the brain stem lesion and pathological yawning, possibly related to denervation hypersensitivity of a putative brain stem yawn centre. Excessive yawning may herald brain stem ischaemia.
两例累及脑桥上段和脑桥中脑交界处的脑干卒中患者出现短暂性过度病理性打哈欠,伴有步态共济失调,其中一例还伴有上肢和面部偏瘫。推测脑干病变与病理性打哈欠之间存在因果关系,可能与假定的脑干哈欠中枢的去神经超敏反应有关。过度打哈欠可能预示着脑干缺血。
