The diagnosis and treatment of dizziness.

Dizziness is a complex and frustrating symptom of potentially numerous causes. The history and physical examination can elicit the category that best characterizes the dizziness: vertigo, presyncope, dysequilibrium, or lightheadedness. If the cause of dizziness cannot be found or treated directly, medications may suppress symptoms. Surgery for vertigo includes conservative and destructive procedures. Rehabilitation is often a useful adjunct in the treatment of many types of dizziness.
