Vocal cord dysfunction is when the vocal cords adduct (come together) when breathing resulting in shortness of breath and at its worst, complete airway obstruction resulting in stridor known as laryngospasm.
The video shown here shows a patient with exercise induced vocal cord dysfunction (her breathing attacks occur only with exercise). The first part of the video shows this patient at rest breathing normally. The latter half of the video shows the patient after exercising and suffering from a mild case of vocal cord dysfunction.
Treatment depends on finding the trigger and addressing the trigger whether it be allergy, reflux, etc. If all possible triggers have been ruled-out, neuropathic medications like neurontin and elavil can be tried. If the side effects are unacceptable or the medications just do not work, botox injections to the vocal cords can be performed.
Speech therapy can also be pursued in order to learn coping mechanisms to help a patient deal with an attack when it happens.
