Practical approach to vertigo: a synthesis of the emerging evidence

Vestibular presentations represent a large financial and symptomatic burden of disease1,2 , while remaining one of the most elusive presentations to accurately and confidently diagnose. A primary cause for this is that the same symptom can be the end-product of numerous aetiologies, and uncertainties can lead to unnecessary investigations and associated increased cost and delays in diagnosis. An effective method to narrow the diagnosis is firstly to determine, from a limited list, which type of vestibular syndrome the patient possesses, and then apply a focussed history and examination to define the most likely aetiology within that syndrome. This review provides a diagnostic approach to the vertiginous patient, outlining the underlying pathophysiology that accounts for the clinical symptoms and signs. With this approach, physicians should be able to diagnose the majority of common vestibular presentations and know when to refer the urgent, complex, or rare cases to sub-specialist neuro-otologists for prompt and appropriate management.
