Vocal cord dysfunction (VCD) causes breathing difficulty due to paradoxical vocal cord closure during inhalation. Misdiagnosis as asthma is common, but speech therapy can be effective.

Area of Science:

Medicine
Pulmonology
Otolaryngology

Background:

Vocal cord dysfunction (VCD) involves paradoxical vocal cord adduction during inspiration.
Symptoms include dyspnea, wheezing, and chest tightness, often mimicking asthma.
Misdiagnosis can lead to inappropriate asthma treatments.

Purpose of the Study:

To describe the characteristics, diagnosis, and management of vocal cord dysfunction.
To highlight diagnostic challenges and differentiate VCD from asthma.
To review therapeutic options for VCD.

Main Methods:

Review of clinical presentation and diagnostic methods for VCD.
Discussion of differential diagnosis, particularly with asthma.
Evaluation of treatment modalities, including speech therapy and psychological counseling.

Related Experiment Videos

Main Results:

Paradoxical vocal cord adduction during inspiration is the hallmark of VCD.
Laryngoscopy is the gold standard for diagnosis, but clinical history and pulmonary function tests can offer clues.
Speech therapy and psychological support are often beneficial.

Conclusions:

Vocal cord dysfunction is a distinct entity often confused with asthma.
Accurate diagnosis is crucial to avoid ineffective asthma treatments.
Further research is needed on the natural course and prognosis of VCD.
