Abstract:
Two patients with a chronic, barking cough were diagnosed with psychogenic cough. Using an original cough counter we studied the nocturnal cough count and pattern. While the number of coughs when awake was extremely high for both patients, the number of coughs was remarkably reduced during sleep, similar to an exacerbation of asthma. Moreover, the properties of the coughs when awake were clearly different from those of coughs during sleep. In conclusion, an objective examination using a cough counter was useful for the diagnosis, treatment and management of psychogenic cough.
