Psychogenic vocal cord dysfunction simulating bronchial asthma

Upper airway obstruction can mimic bronchial asthma. A particular type results from psychogenic dysfunction of the vocal cord, and presents as bronchial asthma or organic upper airways obstruction. If not recognized, ineffective and potentially harmful therapy is given instead of focusing on the underlying psychopathology. We report three Saudi females with this condition, in whom polygamy and a large family system created associated social stress. Spirometry with a flow volume loop showed characteristic features, and in all three this test was the most important clinical tool that led to the correct diagnosis. Clinicians should perform spirometry and flow-volume loop tests routinely in patients presenting with asthmatic symptoms, and look for clues suggestive of this condition, including a psychosocial assessment.
