Persistent Postural-Perceptual Dizziness: Up to date

Persistent postural-perceptual dizziness: a useful new syndrome

Clinical characteristics of patients with persistent postural-perceptual dizziness.

INTRODUCTION Persistent postural-perceptual dizziness is the dizziness that lasts for over three months with no clinical explanation for its persistence. The patient's motor response pattern presents changes and most patients manifest significant anxiety. OBJECTIVE To evaluate the clinical characteristics of patients with persistent postural and perceptual dizziness. METHODS statistical ana...

Persistent Postural-Perceptual Dizziness: A Matter of Higher, Central Dysfunction?

OBJECTIVE Persistent postural-perceptual dizziness (PPPD) is the most common vestibular disorder in the age group between 30 and 50 years. It is considered to be based on a multisensory maladjustment involving alterations of sensory response pattern including vestibular, visual and motion stimuli. Previous data supported a link between vestibular and pain mechanism. The aim of the study was to ...

Persistent postural-perceptual dizziness (PPPD): a common, characteristic and treatable cause of chronic dizziness.

Persistent postural-perceptual dizziness (PPPD) is a newly defined diagnostic syndrome that unifies key features of chronic subjective dizziness, phobic postural vertigo and related disorders. It describes a common chronic dysfunction of the vestibular system and brain that produces persistent dizziness, non-spinning vertigo and/or unsteadiness. The disorder constitutes a long-term maladaptatio...

Altered Insular and Occipital Responses to Simulated Vertical Self-Motion in Patients with Persistent Postural-Perceptual Dizziness

BACKGROUND Persistent postural-perceptual dizziness (PPPD) is a common functional vestibular disorder characterized by persistent symptoms of non-vertiginous dizziness and unsteadiness that are exacerbated by upright posture, self-motion, and exposure to complex or moving visual stimuli. Recent physiologic and neuroimaging data suggest that greater reliance on visual cues for postural control (...
