Dizziness is a common reason for outpatient neurology consultation. Oftentimes, a complete workup by general practitioner, including MRI brain fails to reveal a cause. Some patients would have also undergone an ENT evaluation before approaching neurology for an answer. Such scenarios provide a challenge as well as opportunity for the neurologist to exercise their knowledge and clinical skills in arriving at a diagnosis. Conditions like 'Unspecified Vestibular Dysfunction' and 'Presbyvertigo' are often the underlying causes, which are either not recognized or misdiagnosed as BPPV, psychogenic or perceptive dizziness. This article's goal is to help understand vestibular system and diagnose vestibular dysfunction in clinical practice.
头晕是门诊神经科会诊的常见原因。通常,全科医生进行的全面检查,包括脑部磁共振成像(MRI),都无法找出病因。有些患者在向神经科寻求答案之前,也会先接受耳鼻喉科评估。这种情况既给神经科医生带来了挑战,也为他们运用知识和临床技能进行诊断提供了机会。诸如“未明确的前庭功能障碍”和“老年眩晕”等病症往往是根本原因,这些病因要么未被识别,要么被误诊为良性阵发性位置性眩晕(BPPV)、心因性或感知性头晕。本文的目的是帮助理解前庭系统,并在临床实践中诊断前庭功能障碍。
