Cough is one of the cardinal symptoms of respiratory tract disorders and could be a manifestation of a serious non-respiratory tract disease. Cough is generated by an integrated mechanism between the central nervous and respiratory systems. The triggering factor of the above integration is an initial irritant, which stimulates the cough reflex and, hence, the mechanism of cough will take place. Persistent cough in a non-smoking adult is considered one of the most common presentations to physicians practicing in hospital or primary care settings and can be caused by many disorders.
