Synopsis

Also known as Dejerine syndrome. Vertebral-basilar arterial disease affecting the medial medulla that causes limb weakness, hemisensory loss, and tongue weakness. Very rare. Represents less than 1% of brainstem stroke syndromes. Patient will appear ill. Other characteristic findings include unilateral contralateral hemiparesis or hemiplegia, flaccid paralysis, dysarthria, dysphagia, headache, nystagmus, nausea, vomiting, and spasticity. Prognosis is fair, with affected patients regaining motor strength with minimal remaining effects.
