Pathological Yawning as a Presenting Symptom of Brain Stem Ischaemia in Two Patients JNNP 77:98-100,3, Cattaneo,L.,et al, 2006 See this aricle in Pubmed Article Abstract 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 brains tem yawn center. Excessive yawning may herald brain stem ischaemia.
