DOI: 10.1007/s00415-024-12415-z
Abstract: Patients with persistent postural-perceptual dizziness (PPPD) perceive postural instability larger than the observed sway. It is unknown whether the concept of postural misperception prevails during vestibular stimulation and whether it may account for the unsteadiness… read more here.

DOI: 10.3389/fneur.2021.652366
Abstract: Background: Persistent postural-perceptual dizziness (PPPD) is a persistent chronic vestibular syndrome exacerbated by upright posture/walking, active or passive motion, and exposure to moving or complex visual stimuli. PPPD has four precursors: phobic postural vertigo, space-motion… read more here.

DOI: 10.3389/fneur.2025.1642869
Abstract: Persistent postural-perceptual dizziness (PPPD) is characterized by one or more symptoms of dizziness, unsteadiness, or non-spinning vertigo, which persist on most days for at least 3 months. The most common symptom of PPPD worsens when… read more here.
