Dizziness is a nonspecific term and may be used by patients to indicate true vertigo, lightheadedness, imbalance, or a form of syncope. The prevalence of dizziness in the general population ranges from 15% to 30%. True vertigo is described as a rotary sensation of the patient or surroundings, and is often of vestibular origin.
The etiology varies from vestibular, to neurologic, to cardiovascular pathology. The most common causes of vertigo are migraine-related vertigo, benign positional paroxysmal vertigo, and Meniere disease. Cerebellar infarct or vestibular schwannoma (acoustic neuroma) may also cause dizziness.
