Evaluation and management of the dizzy patient.

Evaluation and management of the dizzy patient remains frustrating to both the patient and physician. Numerous disorders may induce dizziness; these include not only inner ear disoders but also various central nervous system, ocular, and general systemic disturbances. Since dizziness has many variations, the subtle nuances the symptom may manifest must be explored throughly. Similarly, a consistent approach to the patient's physical and larboratory examination must be taken to understand the pathophysiology of the dizziness. This includes comprehensive auditory and vestibular evaluation, complete neurologic and ophthalmologic examination, and laboratory evaluation for latent or manifest systemic disease. The management of dizziness and vertigo is largely symptomatic. Certain exceptions exist where specific medical and surgical approaches may be beneficial, but the limitations of such treatment must be appreciated.
