Persistent Postural-Perceptual Dizziness

PPPD, chronic dizziness worsened by upright posture and busy visual scenes

Overview

Persistent postural perceptual dizziness, PPPD, is a chronic functional vestibular disorder defined by the Barany Society in 2017. People experience non spinning dizziness or unsteadiness on most days for three months or more, worse when standing or walking, when moving, and in visually busy places such as supermarkets. It often begins after an acute balance problem such as vestibular neuritis, BPPV, or a panic attack, after which the brain stays in a heightened balance control mode. Vestibular rehabilitation, cognitive behavioural therapy, and certain medications are recognized approaches.
