If Dix-Hallpike Produces Non-Fatiguable Nystagmus...

BPPV always produces a nystagmus that weakens with repetitive Dix-Hallpike maneuvers. When it does not fatigue, it argues against BPPV and suggests either a brain or spine issue... most commonly cervicogenic vertigo is present.

In this situation, seeing a neurologist is the next appropriate step to evaluate the dizziness further and potentially a spine surgeon.
