PPPD calculator

Have you had dizziness, unsteadiness, or non-spinning vertigo on most days for at least 3 months?

"Most days" means more days than not. Non-spinning vertigo includes feelings like floating, swaying, rocking, or being unsteady on your feet — not the room-spinning kind of vertigo.

When the symptoms occur, do they typically last hours at a time — even if they wax and wane in intensity?

PPPD symptoms don't have to be continuous through the whole day, but each stretch of symptoms should be prolonged — hours rather than seconds or minutes. They often build through the day.

Did the dizziness start during or after some kind of triggering event?

Examples: an earlier spell of vertigo (BPPV, vestibular neuritis, Ménière's, vestibular migraine), a head or neck injury, a significant illness affecting balance (concussion, infection, autonomic problem), or a period of severe anxiety or panic. PPPD usually develops in the aftermath of something that destabilized your vestibular system. If you can't pinpoint any trigger, this criterion is less likely to be met.

Do these symptoms cause you significant distress, or interfere with your work, social life, or daily activities?

Mild dizziness that you barely notice doesn't qualify. The PPPD criteria require the symptoms to genuinely affect how you function or how you feel.

Has another condition already been identified that better explains these symptoms?

For example: an active inner-ear disorder, a neurological disease, a severe anxiety disorder that on its own explains everything, or a medication side effect. PPPD often coexists with other conditions, but criterion E asks whether another diagnosis already accounts for the whole picture. If you haven't been evaluated, answer "No" — but this question can only really be confirmed by a clinician.
