Vocal Cord Dysfunction (VCD) also known as Paradoxical Vocal Fold Movement (PVFM) occurs when the vocal cords (voice box) do not open correctly. This disorder is also referred to as paradoxical vocal fold movement.
Symptoms of asthma and VCD are alike that’s why VCD is sometimes confused with asthma. Many people with asthma also have VCD but unlike asthma, VCD is not an allergic response starting in the immune system. Although the two may have similar triggers and symptoms, the treatment approach for VCD is very different than treatments used to manage and control asthma. This makes proper diagnosis essential.
