Course Overview
Chronic cough is a prevalent and often debilitating condition, affecting a significant portion of the adult population. Characterized by a cough lasting longer than eight weeks, it is frequently resistant to initial treatments and can persist for years. Despite repeated clinical evaluations, many patients continue to suffer without a clear diagnosis or effective therapeutic plan. Modern research has identified that hypersensitivity of the vagal afferent neurons—both in the airway and in central nervous system projections—plays a central role in chronic cough, regardless of the initial cause or any concurrent conditions. This physiological shift redefines chronic cough as a distinct clinical entity rather than a mere symptom of another disorder. Recognizing this distinction is essential for clinicians in selecting appropriate diagnostic and therapeutic strategies (Source: National Institutes of Health).
