Risk factors of primary benign paroxysmal positional vertigo

Abstract

Benign paroxysmal positional vertigo (BPPV) is the most common kind of vertigo, which can be divided into idiopathic and secondary types. Head trauma, surgery, and inner ear diseases may induce the secondary BPPV, but the etiology and pathogenesis of idiopathic BPPV is still unknown. Recent studies indicate that multiple factors are associated with idiopathic BPPV; in this article we will review the risk factors of idiopathic BPPV.
