Benign paroxysmal positional vertigo (BPPV) is the commonest cause of dizziness. It is characterised by brief episodes of vertigo and imbalance with nystagmus. The direction of nystagmus allows the identification of the culprit semicircular canal. As it is readily treatable—and often curable—BPPV should not be missed. Although recurrent episodes of vertigo triggered by movement suggest BPPV, the diagnosis can only be confirmed with the Dix-Hallpike manoeuvre. Here we review the diagnostic manoeuvres required to diagnose BPPV, and the various repositioning manoeuvres for treating different types of BPPV.
