Reliability and Validity of a Lithuanian version of Leicester Cough Questionnaire

Chronic cough is the most common complain during the visit to a pulmonologist. Cough is described as a protective reflex that removes excessive secretions and inhaled foreign bodies from the respiratory tract. The anatomy of respiratory tract which is plentiful of cough receptors is the reason, that the most frequently causes of chronic cough are upper airway disorders, asthma and gastroesophageal reflux. There is some controversy if these conditions are aggravants or causes of cough. What is more, many people have a cough reflex sensitivity and their cough cannot be expalined [2,3].
