Aging significantly impacts asthma severity and presentation in older adults, often leading to underdiagnosis and undertreatment. Understanding aging as a comorbidity is crucial for effective asthma management in the elderly.
Area of Science:
- Gerontology
- Pulmonology
- Immunology
Background:
- The global population is aging rapidly, with a corresponding increase in elderly individuals (over 65 years) experiencing asthma.
- Asthma in the elderly is frequently under-diagnosed, misdiagnosed, and undertreated, often presenting with increased severity and reduced remission.
- Comorbidities are common in older adults, complicating asthma assessment and management.
Purpose of the Study:
- To explore the multifaceted factors that support considering aging itself as a distinct comorbidity in adult asthma.
- To highlight how age-related changes influence asthma presentation, diagnosis, and treatment outcomes.
Main Methods:
- Review of current literature on aging, lung physiology, and immune system changes in the elderly.
- Analysis of how age-related structural and functional lung alterations impact asthma.
- Examination of age-related immune system modifications and their effect on airway inflammation and asthma response.
Main Results:
- Aging involves structural and functional lung changes that can exacerbate asthma.
- Age-related immune system alterations increase susceptibility to pathogens and modify airway inflammation, affecting asthma manifestation and treatment response.
- The interplay of aging, comorbidities, and asthma presents unique diagnostic and therapeutic challenges.
Conclusions:
- Aging should be recognized as a significant comorbidity in elderly asthma patients.
- Physicians must consider age-specific physiological and immunological changes when managing asthma in older adults.
- A comprehensive approach is needed to address the complexities of asthma in the aging population.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
