Benign paroxysmal positional vertigo causes brief episodes of mild to intense dizziness.
What are the diagnostic clues for central localization of vertigo?
Diagnostic clues for central localization are: presence of other neurologic signs, additional ocular motor and vestibular abnormalities, nystagmus without vertigo, atypical direction nystagmus, rapid vertigo recurrence and poor response to repositioning maneuvers.
When to see a doctor for benign paroxysmal positional vertigo?

The otoconia move to the lowest part of the canal, which causes the fluid to flow within the SCC, stimulating the balance (eighth cranial) nerve and causing vertigo and jumping eyes (nystagmus). People with BPPV can experience a spinning sensation — vertigo — any time there is a change in the position of the head.

What is the Hallmark nystagmus of paroxysmal positional vertigo (PC-BPV)?
The hallmark nystagmus of PC-BPV is induced by the Dix-Hallpike test in which the patient’s head is turned towards the affected ear and lowered into a head-hanging position so that the posterior canal is in the sagittal plane with the ampulla at the highest gravitational point.
