Persistent Postural-Perceptual Dizziness: Overview and Diagnostic Criteria

  • 1Department of Neurology, College of Medicine, Ewha Womans University, Mokdong Hospital, Seoul, Korea


Persistent postural perceptual dizziness (PPPD) is a chronic functional vestibular disorder that manifests with 3 or more months of dizziness, nonspinning vertigo, and unsteadiness. These main symptoms are exacerbated by upright posture, active or passive self-motion, and exposure to visual stimuli. PPPD is usually precipitated by illnesses that cause vertigo, dizziness, or unsteadiness. The common precipitants are acute or episodic peripheral vestibular diseases including vestibular neuritis, Meniere disease, or benign paroxysmal positional vertigo. PPPD is not a diagnosis of exclusion. An abnormal finding on examination or laboratory testing does not necessarily exclude a diagnosis of PPPD. This article reviewed the Bárány Society’s diagnostic criteria for PPPD in detail and discussed directions of future investigations.
