[Vertigo/Dizziness as a Common Disease: Thinking in Terms of Risk].

Vertigo and dizziness are among the most common chief complaints in the neurology and emergency departments. Benign, self-limiting peripheral causes such as benign positional paroxysmal vertigo or vestibular neuropathy, Ménière's disease are the majority, but dangerous underlying conditions such as cerebrovascular or cardiovascular diseases are still overlooked. In this paper, the anatomy of the vestibular network from peripheral to central and the classification based on "triggers and timing" rather than the analysis of patient's word (rotational versus dizzy) are presented.
