Persistent Postural-Perceptual Dizziness: Overview and Diagnostic Criteria: Sung-Hee Kim; Res Vestib Sci. 2020;19(2):42-48. Published online June 15, 2020; DOI: https://doi.org/10.21790/rvs.2020.19.2.42

Abstract PDF: 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.

Dizziness in Traumatic Brain Injury: Visual-Vestibular Dysfunction, Neurotological Approach: Seong-Hae Jeong; Res Vestib Sci. 2019;18(2):27-31. Published online June 15, 2019; DOI: https://doi.org/10.21790/rvs.2019.18.2.27

Abstract PDF: Traumatic brain injury (TBI) could give rise to variable clinical manifestations based on the involved structures of our bodies. Although there are no structural abnormalities proven, the patients with mild TBI suffer from chronic dizziness and imbalance. Herein, I will discuss the visuo-vestibular interaction and neurotological finding in TBI, which could demonstrate the clue to the diagnosis and management in dizzy patients with TBI.
