    Vocal cord dysfunction can mimic asthma symptoms like wheezing and shortness of breath. This condition, often a conversion reaction, effectively treated with speech and psychotherapy.

    Area of Science:

    • Pulmonology
    • Psychiatry

    Background:

    • Vocal cord dysfunction (VCD) can present with symptoms mimicking bronchial asthma.
    • Patients with VCD often experience refractory wheezing and dyspnea unresponsive to standard asthma treatments.

    Purpose of the Study:

    • To describe a syndrome of vocal cord dysfunction that mimics asthma.
    • To investigate the diagnostic features and treatment outcomes for this condition.

    Main Methods:

    • Case series of five patients presenting with asthma-like symptoms.
    • Diagnostic evaluation included flow-volume loops and laryngoscopy.
    • Treatment involved speech therapy and psychotherapy.

    Main Results:

    • Patients exhibited variable extrathoracic obstruction during wheezing episodes.

    Related Experiment Videos

  • Laryngoscopy revealed vocal cord adduction as the cause of obstruction.
  • All patients showed dramatic improvement with speech and psychotherapy.
  • Standard asthma provocation tests were negative.

    • Conclusions:

    • Vocal cord dysfunction is a potential mimic of bronchial asthma.
    • This syndrome, possibly a conversion reaction, is diagnosed through characteristic flow-volume loops and laryngoscopy.
    • Speech and psychotherapy are effective treatments for vocal cord dysfunction.
