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.
