Blood test could detect Parkinson’s disease before symptoms emerge

Researchers behind test using biomarkers say it could ‘revolutionise’ early diagnosis of disease

Researchers have developed a simple and “cost-effective” blood test capable of detecting Parkinson’s disease long before symptoms emerge, according to a study.

About 153,000 people live with Parkinson’s in the UK, and scientists who undertook the research said the test could “revolutionise” an early diagnosis of Parkinson’s disease, “paving the way for timely interventions and improved patient outcomes”.
