{"pk":17110,"title":"The Clinical Differentiation of Cerebellar Infarction from Common Vertigo Syndromes","subtitle":null,"abstract":"This article summarizes the emergency department approach to diagnosing cerebellar infarction in the patient presenting with vertigo. Vertigo is defined and identification of a vertigo syndrome is discussed. The differentiation of common vertigo syndromes such as benign paroxysmal positional vertigo, Meniere’s disease, migrainous vertigo, and vestibular neuritis is summarized. Confirmation of a peripheral vertigo syndrome substantially lowers the likelihood of cerebellar infarction, as do indicators of a peripheral disorder such as an abnormal head impulse test. Approximately 10% of patients with cerebellar infarction present with vertigo and no localizing neurologic deficits. The majority of these may have other signs of central vertigo, specifically direction-changing nystagmus and severe ataxia.\n\n\n[West J Emerg Med. 2009;10(4):273-277.]","language":"en","license":{"name":"none","short_name":"none","text":"","url":"http://google.com"},"keywords":[{"word":"vertigo"},{"word":"Cerebellar infarction"},{"word":"Physical Examination"},{"word":"direction-changing nystagmus"},{"word":"gait"},{"word":"Emergency Medicine"}],"section":"Article","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6gt0d3x7","frozenauthors":[{"first_name":"James","middle_name":"A","last_name":"Nelson","name_suffix":"","institution":"University of California at San Diego, Department of Emergency Medicine","department":"None"},{"first_name":"Erik","middle_name":"","last_name":"Viirre","name_suffix":"","institution":"University of California, San Diego","department":"None"}],"date_submitted":"2008-03-22T07:00:00Z","date_accepted":"2008-03-22T07:00:00Z","date_published":"2009-11-01T07:00:00Z","render_galley":null,"galleys":[{"label":"","type":"pdf","path":"https://journalpub.escholarship.org/westjem/article/17110/galley/8646/download/"}]}
