Early diagnosis and treatment of Parkinson’s disease is critical to slowing its progression. Long before neurological symptoms appear, patients exhibit early signs, some of which are associated with specific chemical scent signatures known as volatile organic compounds. Researchers study these as early biomarkers of disease for future diagnostics applications. In this episode, Iris Kulbatski from The Scientist spoke with Drupad Trivedi, a University of Manchester biomedical researcher and lecturer in analytical and measurement science, to learn more about how fatty skin secretions in Parkinson’s disease and one woman’s sensitive nose may lead to early detection and intervention.
