Asthma, COPD, & Asthma-COPD Overlap: A Quiz in Differential Diagnostics

Veronica Hackethal, MD

Distinguishing asthma and COPD can at times be problematic and the asthma-COPD overlap picture is even less clear. Check your recall of GINA/GOLD guidelines on all 3.

Symptoms of asthma and COPD can sometimes overlap, complicating diagnosis and treatment, and particularly in persons who smoke and in older adults. The term asthma-COPD overlap does not describe a single disease entity; it likely includes patients with different disease phenotypes caused by a range of disease mechanisms.

This quiz tests your knowledge of guideline-recommended issues surrounding diagnosis of asthma, COPD and asthma/COPD overlap and is based on the joint recommendations compiled in 2017 by the Global Initiative for Asthma (GINA) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD).
