Parkinson's Early Biomarker Discovery

Researchers at Chalmers University of Technology and Oslo University Hospital have identified biomarkers for Parkinson s disease in its earliest stages, before significant brain damage occurs. This discovery, published in npj Parkinson's Disease, reveals a critical window of opportunity for early diagnosis via blood tests, which could be implemented in healthcare within five years. The study, led by Annikka Polster and with Danish Anwer as the first author, focused on DNA damage repair and cellular stress response, identifying unique gene activity patterns in early-stage patients. This advancement offers hope for developing new treatments or repurposing existing drugs to prevent or slow the disease's progression, which currently affects over 10 million people globally and is projected to double by 2050.
