Distinguishing and treating causes of central vertigo.
A patient's dizziness can be caused by a peripheral vestibular disorder, VIIIth nerve compression, brain stem ischemia, or cerebellar stroke. Clues from the history and physical examination are mentioned, and diagnostic entities, such as demyelination, cerebrovascular disease, migraine, Arnold-Chiari malformation, cerebellar degeneration, and neoplastic disease are discussed. Treatment options are outlined so that therapeutic and diagnostic trials can be initiated. Guidelines are offered for when to image the brain or posterior circulation vasculature and when a patient with acute vertigo should be admitted for observation.
