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.
