[Research progress on the questionnaire related to persistent postural-perceptual dizziness].

Persistent postural-perceptual dizziness（PPPD） is the most common chronic vestibular disease, the clinical manifestation is dizziness, unstable and non-rotational dizziness for three months or more. And the symptom is exacerbated by upright posture, active or passive movement, and complex visual stimuli. In addition, PPPD is a functional disease, so routine vestibular function tests and imaging tests are often negative. According to the diagnostic criteria established by the Barany Association, the diagnosis of PPPD often relies on history. This article provides a review of PPPD-related questionnaires.摘要: 持续性姿势-知觉性头晕（persistent postural-perceptual dizziness，PPPD）是最常见的慢性前庭疾病，其临床表现为持续3个月以上的头晕、不稳和非旋转性眩晕，并因直立姿势、主动或被动运动和复杂视觉刺激而加重。PPPD属于功能性疾病，故常规前庭功能检查及影像学检查往往呈阴性。根据 Bárány协会制定的诊断标准，PPPD诊断依靠病史。本文就PPPD相关问卷展开综述。.
