Answer: B. False. Smokers and individuals exposed to other noxious agents may develop a mixed picture, with airflow limitation suggestive of COPD accompanied by both asthma- and COPD-like inflammation. Elderly patients and some patients with chronic asthma may exhibit asthma-COPD overlap. Drawing a clear distinction between asthma and COPD in these patients may be difficult using current imaging techniques and physiologic testing.3
