The purpose of this chapter is to describe various disorders not described elsewhere in this text that may present as asthma, coexist with asthma, or be confused with asthma. The cardinal symptoms of asthma—cough, wheezing, and dyspnea—are associated with nearly all respiratory illnesses. Because asthma is a common disorder, it is a widespread practice to initially treat the syndrome of cough, wheeze, and dyspnea with bronchodilators or inhaled corticosteroids to determine whether they respond to treatment. When such treatment is unsuccessful or only partially effective, then further evaluation may be necessary, including lung imaging, comprehensive lung function testing, inhalation challenge testing with methacholine or mannitol, and more extensive examination of the upper airway.
