Abstract

Asthma in older adults affects quality of life and results in a higher hospitalization rate and mortality. In common clinical practice, asthma in the elderly is underdiagnosed and undertreated or overdiagnosed and mistreated. The age-related reduction in perception of shortness of breath and the high incidence of comorbidities make the diagnosis and management more difficult and challenging for the physicians. Chronic obstructive pulmonary disease (COPD) is usually easy to distinguish from asthma, but sometimes the distinction from late-onset asthma in older patients, particularly in cigarette smokers, is difficult and may be impossible. Both diseases are characterized by the presence of airflow obstruction but have distinct pathogenesis, inflammatory pattern, and prognosis. The distinction between Asthma and COPD based simply on spirometric parameters is difficult especially in the elderly asthmatics. The combination of lung function testing, bronchial hyperresponsiveness (BHR) and atopy status, HRCT scans, and the newly developed biological techniques, allowing the assessment of biomarker profiles, could facilitate the distinction between these diseases.
