what does vertigo means
Vertigo is a sensation of spinning while stationary. It is commonly associated with nausea or vomiting, unsteadiness (postural instability), falls, changes to a person's thoughts, and difficulties in walking. Recurrent episodes in those with vertigo are common and frequently impair the quality of life.
Vertigo is a problem in a part of the vestibular system. Other causes of dizziness include presyncope, disequilibrium, and non-specific dizziness. Benign paroxysmal positional vertigo is more likely in someone who gets repeated episodes of vertigo with movement and are otherwise normal between these episodes.
