Earwax as a Potential Early Indicator of Parkinson’s Disease
Researchers in China found that earwax contains specific volatile organic compounds (VOCs) that differ in people with Parkinson's disease, suggesting earwax could be used as a non-invasive, accessible diagnostic indicator for early detection of the condition, which affects 10 million globally. The study demonstrated a 94% accuracy in categorizing Parkinson's status using VOC data, highlighting the potential for a simple test to identify at-risk individuals before severe symptoms develop.
