VCD & Chronic Cough

Vocal Cord Dysfunction & Chronic Cough…

Vocal cord dysfunction (VCD) is an upper airway disorder characterized by difficulty breathing, particularly upon inhalation (whereas asthma affects exhalation). Symptoms may include episodes of noisy inhalation, throat/neck tightness, chronic dry cough, and/or changes to vocal quality.  Laryngospasm, or an undesired closure of the vocal cords, is common in VCD. Triggers for VCD may include tickling in the throat, post-nasal drip, acid reflux, inhaled irritants (e.g.: perfume, cold air), dry mouth/throat, exertion, and/or stress/anxiety.  VCD responds poorly to asthma medication. Another name for VCD is paradoxical vocal fold movement (PVFM).

Chronic cough or habitual cough is dry in nature without an underlying cause such as allergies or asthma. Chronic or habitual cough may appear and persist after full recovery from an upper respiratory infection (eg: cold/flu, pneumonia, COVID-19).
