Israeli test detects Parkinson's early via blood

Israeli researchers have developed a blood test for early detection of Parkinson's disease, potentially allowing for earlier treatment and improved outcomes. The PCR-based test identifies the disease before symptoms appear by analyzing transfer RNA fragments in the blood, with 86% accuracy in early-stage patients. This method could revolutionize diagnosis, allowing for intervention before significant brain damage. The study, led by Professor Hermona Soreq, used samples from 60 Parkinson's patients and 60 controls. Researchers are now seeking FDA approval and investigating the underlying biological mechanisms.
