BPPV — NPTE Cheat Sheet

  • What it is: Otoconia displaced into a semicircular canal (ear crystals where they shouldn’t be).
  • Classic signs: Brief vertigo (<60 sec), triggered by position changes, upbeating torsional nystagmus, no hearing loss.
  • Rule-in test: Dix-Hallpike.
  • Rule-out clues: Long-lasting vertigo, neuro deficits, hearing symptoms → think neuritis/Ménière’s.
  • NPTE trap: Nystagmus >60 seconds = NOT typical BPPV (think cupulolithiasis).
  • Best treatment: Epley every. single. time.
  • Mock question included: Yes — test yourself before you move on.
