New Genetic Study Uncovers Neurological Roots of Chronic Cough

London: A groundbreaking study led by the University of Leicester, in collaboration with the University of Copenhagen and Queen Mary University of London, has identified key neurological mechanisms underlying chronic cough.

The findings, published in the European Respiratory Journal, represent the largest and most diverse genetic investigation into the condition to date.

The study analyzed data from nearly 30,000 individuals suffering from chronic cough, drawing on multiple population health resources, including the UK Biobank, EXCEED Study, Copenhagen Hospital Biobank, Genes & Health, and the eMERGE Network.

Researchers discovered that genes involved in neuronal signaling and sensory pathways play a central role in chronic cough, pointing to a neurological basis for the condition.

This marks a significant advance in understanding cough reflex hypersensitivity as a nervous system-mediated process and could pave the way for the development of new, more effective treatments.

Importantly, the study also revealed shared genetic factors between chronic cough and chronic pain, suggesting overlapping neurological mechanisms. This insight offers a promising foundation for further research and could inform strategies for managing both conditions more effectively.

“Our study represents a major step forward in understanding the biological mechanisms underlying chronic cough, and we hope it will guide the development of future therapies,” said Dr. Kayesha Coley, lead author and member of the University of Leicester’s Genetic Epidemiology group.

Chronic cough significantly affects quality of life, often causing fatigue, breathlessness, disturbed sleep, and emotional distress. For many sufferers, it becomes a debilitating condition, interfering with daily activities and social interactions.
