title: Acute Diagnosis and Management of Stroke Presenting Dizziness or Vertigo.
abstract: Stroke involving the brainstem and cerebellum frequently presents acute vestibular syndrome. Although vascular vertigo is known to usually accompany other neurologic symptoms and signs, isolated vertigo from small infarcts involving the cerebellum or brainstem has been increasingly recognized. Bedside neuro-otologic examination can reliably differentiate acute vestibular syndrome due to stroke from more benign inner ear disease. Sometimes acute isolated audiovestibular loss may herald impending infarction in the territory of the anterior inferior cerebellar artery. Accurate identification of isolated vascular vertigo is very important because misdiagnosis of acute stroke may result in significant morbidity and mortality.
