Symptoms of BPPV include vertigo (spinning sensation when you change change the position of the head), nausea or vomiting, and totatory (torsional) nystagmus (eye rotates abnormally). BPPV can be caused by head injury or aging. Dix-Hallpike test and roll tests are often used to diagnose BPPV. You may also need Electronystagmography (ENG) or videonystagmography (VNG), MRI test. BPPV may go away on its own within a few weeks or month. If the condition is severe, canalith repositioning maneuvers is often adopted. Medication and surgery are needed in rare situations.
