title: A practical approach to dizziness. Questions to bring vertigo and other causes into focus.
abstract: Evaluation of a patient presenting with dizziness begins with and largely depends on the patient's history. The diagnosis often can be accurately determined in a primary care setting when a stepwise algorithmic approach is used. The first step is getting a detailed account of precisely what the patient means by "dizziness." This helps determine whether the cause is vertigo or another condition, such as orthostatic hypotension. Establishing whether the vertigo is central or peripheral in origin and, if peripheral, how long episodes last further focuses the investigation. Certain clues on physical examination and appropriate use of diagnostic tests help support the diagnosis. Referral should be contemplated when significant central disease is suspected and when vertigo of peripheral origin is persistent or atypical.
