🌀 BENIGN PAROXYSMAL POSITIONAL VERTIGO (BPPV)

One of the most common causes of episodic vertigo is not a problem of the brain — but a problem of where the otoconia are located.

In BPPV, otoconia normally attached to the utricular macula become displaced and enter a semicircular canal, most commonly the posterior semicircular canal.

When the head changes position:

🔹 The displaced otoconia move within the canal.
🔹 This generates abnormal endolymphatic flow.
🔹 The cupula of the ampulla is deflected.
🔹 Vestibular hair cells are stimulated abnormally.
🔹 The brain receives an inappropriate signal of head movement → brief positional vertigo and characteristic nystagmus.

🎯 Key concept:
BPPV is essentially a mechanical disorder of the vestibular system.

This is why positional tests such as the Dix–Hallpike maneuver are so important — and why canalith repositioning maneuvers, such as the Epley maneuver, can be highly effective.

Understanding the anatomy makes the physiology — and the treatment — much easier to understand.
