Vertigo is defined as an abnormal sensation of body motion or of its surrounding objects. It is a common chief complaint in emergency departments comprising 2 to 3% of these consultations worldwide. Vertigo is classified as peripheral or central, according to its origin, and can also be occasionally mixed, the most common cause of peripheral involvement being benign paroxysmal positional vertigo. The initial findings on clinical evaluation of patients are the clues for making a correct diagnosis. The differentiation between central and peripheral vertigo can be optimized by analysing nystagmus, by using the skew test and the head impulse test (HINTS), as also by performing the appropriate tests to evaluate the integrity of the vestibular-cerebellar pathway. In addition, tonal threshold audiometry could raise the diagnostic sensibility from 71 to 89% on initial approach. Appropriate diagnosis is the principal key for managing this clinical condition.
