ILD
Chronic cough is common and burdensome in ILD, with prevalence rates of 50%–89%. Neuronal sensitization, structural lung changes, and altered cough reflex regulation all contribute to persistent cough in ILD. Interventions that modulate the cough reflex (not by suppressing it pharmacologically but by modifying central/perceptual control) may help. Refractory cough in ILD significantly impairs quality of life, causing physical discomfort, social embarrassment, sleep disturbance, and psychological distress. Cough hypersensitivity symptoms are prevalent in ILD and detrimentally affect quality of life. Behavioral treatment can improve quality of life for many patients. CHEST
