持续性体位感知性头晕

定义

持续性非眩晕性眩晕、不稳或两者均持续三个月或以上。症状在大多数时间里都会出现，通常在一天中不断加重，但可能时好时坏。瞬间耀斑可能自发发生，或在突然运动时发生。受影响的个体在直立、暴露于移动或复杂的视觉刺激以及主动或被动头部运动时感觉最差。这些情况可能不是同样的诱发因素。通常，该疾病发生在急性或偶发性前庭或平衡相关问题之后。症状可能间歇性开始，然后增强。逐渐发作是不常见的。

Persistent non-vertiginous dizziness, unsteadiness, or both lasting three months or more. Symptoms are present most days, often increasing throughout the day, but may wax and wane. Momentary flares may occur spontaneously or with sudden movement. Affected individuals feel worst when upright, exposed to moving or complex visual stimuli, and during active or passive head motion. These situations may not be equally provocative. Typically, the disorder follows occurrences of acute or episodic vestibular or balance-related problems. Symptoms may begin intermittently, and then consolidate. Gradual onset is uncommon.
