Elderly are at increased risk for developing pulmonary disease over time. There has been an increase in the prevalence of and mortality from COPD and asthma in the industrialized world. In addition to the increase in these pulmonary diseases there are changes in the pulmonary function of the elderly due to structural changes with age, changes in gas exchange and changes in ventilatory response. This article reviews the epidemiology, diagnosis, prognosis, and therapy of asthma and briefly discusses the epidemiology and therapy of COPD with the emphasis on our elderly population.
