A Nose to Diagnose: Improving Parkinson’s Diagnosis

Researchers discovered personal odors can alter in people with Parkinson's disease. Based on this, they identified specific markers for Parkinson's in sebum, an oily substance secreted from the skin. They developed a new, non-invasive swab test that can identify Parkinson's with 95% accuracy.
