Which of the following is NOT a typical feature of BPPV?

• A. Vertigo triggered by head-position changes
• B. Brief episodes lasting seconds to minutes
• C. Peripheral origin of vertigo
• D. Vertigo lasting days without positional triggers

Answer: (D)

BPPV presents with vertigo that is tightly linked to how your head is positioned and is usually very brief. The dizziness happens when you move your head into certain positions, and the spinning sensation lasts only seconds to a minute or so before stopping. This pattern comes from displaced otoconia in the semicircular canals causing a transient abnormal input to the vestibular system; once the head movement ends, the stimulus resolves, so the vertigo is episodic rather than continuous. Because the problem is in the inner ear, the vertigo is described as peripheral in origin.

Describing vertigo lasting days without any positional triggers does not fit this pattern. Such a description points to other causes beyond BPPV, whereas the other statements—triggered by head-position changes, brief duration, and peripheral origin—are classic features of BPPV.
