what causes vertigo
Vertigo can be caused by problems in the brain or the inner ear. 1  Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo and is characterized by the brief sensation of motion lasting 15 seconds to a few minutes. Head trauma and neck injury may also result in vertigo, which usually goes away on its own. 2  Cervical vertigo can be caused by neck problems such as impingement of blood vessels or nerves from neck injuries. 3  Migraine, a severe form of headache, may also cause vertigo.
