Vocal cord dysfunction (VCD), generally characterized by paradoxical closure of the vocal cords during inspiration, is a common mimicker of asthma and of other conditions that cause upper airway obstruction. As a result, it is frequently overlooked and often misdiagnosed, resulting in administration of excessive medications or other unnecessary interventions, with resultant morbidity. This article explores the clinical features, proposed causes, diagnostic considerations, and management of VCD, as well as some differences between VCD and asthma that can aid in differentiating these two diagnoses in the clinical setting.
声带功能障碍（VCD）通常表现为吸气时声带出现反常性关闭，是哮喘和其他引起上呼吸道阻塞疾病的常见类似病症。因此，VCD 经常被忽视，并且经常被误诊，导致过度用药或其他不必要的干预，从而产生发病率。本文探讨了 VCD 的临床特征、提出的病因、诊断注意事项和管理，以及 VCD 和哮喘之间的一些差异，这些差异有助于在临床环境中区分这两种诊断。
