The prevalence of idiopathic BPPV is increased among elderly persons and among women, with peak onset between 50 and 60 years of age and a female-to-male ratio of 2:1 to 3:1. Key Clinical Points Benign Paroxysmal Positional Vertigoīenign paroxysmal positional vertigo (BPPV), by far the most common cause of vertigo, is characterized by brief spinning sensations, which are typically induced by a change in head position with respect to gravity.īPPV involving the posterior canal (the most common type) is diagnosed on the basis of nystagmus beating in an upward and torsional direction, with the top poles of the eyes beating toward the lower ear, as observed when the patient is lying on one side during the Dix–Hallpike maneuver.īPPV involving the horizontal canal is characterized by nystagmus that is either geotropic (beating toward the ground) or apogeotropic (beating toward the ceiling) when the head is turned to either side while the patient is in a supine position.Ĭanalith-repositioning maneuvers (e.g., Epley's and Semont's maneuvers for the posterior canal) are effective treatments for BPPV. 5 Patients with BPPV are at increased risk for falls and impairment in the performance of daily activities. 3 Spontaneous remissions and recurrences are frequent the annual rate of recurrence is approximately 15%. Attacks of BPPV usually do not have a known cause, although cases may be associated with head trauma, a prolonged recumbent position (e.g., at a dentist's office or hair salon), or various disorders of the inner ear. 4 Many patients also have nausea, sometimes with vomiting.
3 Even though patients with BPPV occasionally report persistent dizziness and imbalance, a careful history taking almost always reveals that their symptoms are worse with changes in head position. 3,4 Vertigo typically develops when a patient gets in or out of bed, rolls over in bed, tilts the head back, or bends forward. 1,2 The condition is characterized by brief spinning sensations, usually lasting less than 1 minute, which are generally induced by a change in head position with respect to gravity.
