BPPV is characterized by?

• A. Recurrent acute onset of vertigo and nystagmus precipitated by head position related to gravity
• B. Chronic dizziness unrelated to head movement
• C. Vertigo only at night
• D. Hearing loss with vertigo

Answer: (A)

BPPV shows up as brief, recurrent spells of vertigo that begin with changes in head position relative to gravity, and you can often see nystagmus during the episode. This happens because small crystals (otoconia) become dislodged and move within the semicircular canals, most commonly the posterior canal, causing abnormal fluid movement when the head changes position. The vertigo lasts only seconds to a minute and is triggered by actions like lying down, looking up, or rolling in bed. The other descriptions don’t fit BPPV: chronic dizziness not linked to head movements suggests a different cause, vertigo only at night isn’t typical for BPPV, and hearing loss with vertigo points toward Meniere disease or other labyrinthine disorders.
