Triggers of Vertigo
Selected triggers of vertigo that must be considered are benign paroxysmal positional vertigo (BPPV), labyrinthitis, acoustic neuroma, migraine with vertigo, and cerebral vascular events. Diagnostic tests are indicated to rule out certain problems, such as MRI to exclude a tumor or an acoustic neuroma. Distinct differences noted during a complete assessment may help eliminate certain disorders. BPPV is triggered by a change in physical position and usually lasts less than one minute; the diagnosis can be confirmed by the Dix-Hallpike maneuver. Labyrinthritis is characterized by acute vertigo associated with continuing imbalance, while instability with walking resolves completely between vertigo episodes in Ménière's disease. If abnormal neurologic manifestations are noted during the exam or reported in a patient's account of a vertigo episode, then a transient ischemic attack or stroke must be ruled out by more detailed diagnostic testing.
