Q

What happens in BPPV?

A

BPPV is a peripheral disorder where the otoliths (carbon crystals) from the utricle, detach from the maculae and float around the semi-circular canals.

Q

What causes the vertigo attacks seen in BPPV?

A

Otoliths are not supposed to be found in the semi-circular canals, so when they are floating there, they induce a bigger endolymph flow when the head move

Therefore movement of the head is processed by the brain as bigger as it actually is
