Introduction
Careful clinical assessment through history and examination is key to the evaluation of patients with suspected vertigo.
Distinguishing vertigo from other causes of dizziness is an essential step.
True vertigo requires a history of perceived movement of the patient, or their surroundings.
Other conditions causing dizziness because of global cerebral hypo-perfusion must be excluded, e.g. arrhythmias, haemorrhage or postural hypotension.
