Vocal Cord Dysfunction
Initially described as hysteria and then Munchausen’s stridor, we now recognize vocal cord dysfunction as a functional group of disorders. Exercise and spontaneously occurring phenotypes exist that benefit from different treatments. The former appears to respond to pharmacological pretreatment with an anticholinergic aerosol and the latter may require vocal cord training to learn to relieve the symptoms. The differential diagnosis includes consideration of neurological and anatomical abnormalities. Recognition and effective treatment is important to permit the individual to be involved in activities important to them and to avoid unnecessary and ineffective medical care.
