title: [Vertigo: it all revolves around the physical exam].
abstract: Dizziness is a common complaint in an emergency department. True vertigo, characterized by subjective sensation of rotation of the subject or of objects around the subject, may be peripheral (85%) or central (15%). Patient's history and physical exam identify the etiology of vertigo in more than 70% of patients. Hallpike test is easily performed and crucial for the diagnosis of benign paroxysmal peripheral vertigo. Central vertigo should be suspected and brain imaging performed in the presence of neurological symptoms, in older patients, or when several risk factors for cerebrovascular disease are present.
