Abstract:Dizziness is the commonest chief complaints, and it often presents a significant challenge to the physician, not only because dizziness involves multiple disciplines but also the patient's description are unclear and unreliable usually. Diagnosis of dizziness must be based on a thorough and detailed history and key physical examinations, the classification established in 1972 was more useful than Bárány criteria, which was traditionally divided into four categories: vertigo, dizziness, disequilibrium, and presyncope. Patients have difficulty describing their symptoms accurately but can consistently identify the timing and triggers. The key physical examination include spontaneous nystagmus, positional provoked test, head impulse test, hearing and focal neurological deficits. Satisfactory results can be achieved only by choosing auxiliary examinations reasonably according to the diagnostic criteria of dizziness, gradually establishing hierarchical diagnosis ideas, and comprehensively evaluating and giving comprehensive treatment.
