The cough reflex is an important protective mechanism against aspiration, but it can become hypersensitive if it is mismanaged. Chronic cough, in reality, is a serious medical condition with a high rate of morbidity. Cough hypersensitivity syndrome has now been given a unified paradigm. It's a clinical entity in which chronic cough is the primary symptom, regardless of the underlying disease. Although it is still a theory, new research reveals that abnormal neurophysiology is the most common cause of this illness. Our understanding of cough mechanisms has evolved in tandem with this paradigm shift in recent decades, allowing us to take even more strides forward in the future.
