[Dysfunction of the vocal cords simulating exercise-induced asthma]

Vocal cord dysfunction is a respiratory condition characterized by anomalous adduction of the vocal cords during inspiration, causing significant air flow limitation in the larynx. Few such cases have been described in which dysfunction is triggered by exercise. We report the case of a young women with severe dyspnea appearing as a result of physical activity. We first deal with issues of differential diagnosis in relation to several other diseases, particularly exercise-induced asthma and then discuss therapeutic approaches.
