本文提出了持续性姿势知觉性头晕（PPPD）的诊断标准，将其纳入国际前庭障碍分类（ICVD）。PPPD这个术语是新的，但这种疾病不是。其诊断标准是通过专家对30年来关于恐怖性姿势性眩晕、空间运动不适、视觉眩晕和慢性主观头晕的研究进行详尽回顾而得出的。PPPD表现为头晕、不稳定或非旋转性眩晕的一种或多种症状，这些症状在三个月或更长时间的大多数日子里都会出现，并且会因直立姿势、主动或被动运动以及暴露于运动或复杂的视觉刺激而加剧。PPPD可能是由破坏平衡或导致眩晕、不稳定或头晕的情况引起的，包括外周或中枢前庭障碍、其他医学疾病或心理困扰。PPPD可以单独存在或与其他条件共存。可能的亚型有待未来的鉴定和验证。PPPD的病理生理过程尚不完全清楚。新兴的研究表明，它可能是由姿势控制机制、多感觉信息处理或空间定向和威胁评估的皮层整合的功能变化引起的。因此，PPPD被归类为慢性功能性前庭障碍。它不是一种结构性或精神性疾病。
This paper presents diagnostic criteria for persistent postural-perceptual dizziness (PPPD) to be included in the International Classification of Vestibular Disorders (ICVD). The term PPPD is new, but the disorder is not. Its diagnostic criteria were derived by expert consensus from an exhaustive review of 30 years of research on phobic postural vertigo, space-motion discomfort, visual vertigo, and chronic subjective dizziness. PPPD manifests with one or more symptoms of dizziness, unsteadiness, or non-spinning vertigo that are present on most days for three months or more and are exacerbated by upright posture, active or passive movement, and exposure to moving or complex visual stimuli. PPPD may be precipitated by conditions that disrupt balance or cause vertigo, unsteadiness, or dizziness, including peripheral or central vestibular disorders, other medical illnesses, or psychological distress. PPPD may be present alone or co-exist with other conditions. Possible subtypes await future identification and validation. The pathophysiologic processes underlying PPPD are not fully known. Emerging research suggests that it may arise from functional changes in postural control mechanisms, multi-sensory information processing, or cortical integration of spatial orientation and threat assessment. Thus, PPPD is classified as a chronic functional vestibular disorder. It is not a structural or psychiatric condition.
