Benign recurrent vertigo (BRV), also known as benign paroxysmal positional vertigo (BPPV), is a common disorder affecting up to 2% of the adult population. The majority of individuals with chronic recurrent vertigo have no identifiable cause, no progression of the disorder, and no other neurologic or auditory signs. Many families have multiple affected individuals, suggesting familial transmission of the disorder with moderate to high penetrance (summary by Lee et al., 2006).
