Vocal Cord Dysfunction
Vocal cord dysfunction (VCD), also called paradoxical vocal fold motion, occurs when the vocal cords close instead of opening during breathing. Symptoms mimic asthma but don't respond to typical asthma treatments.

Symptoms
- Sudden difficulty breathing
- Stridor (high-pitched sound on inhalation)

- Triggered by exercise, strong odors, stress, reflux
Diagnosis
- Laryngoscopy during symptoms (definitive)
- Lung function tests (often normal between episodes)
- Exclude asthma and other causes
