Thirteen Blood Biomarkers May Help Diagnose Parkinson’s Earlier, Study Finds

Parkinson’s News Today (3/3, Maia) reports a study found that “thirteen blood biomarkers, including three never previously linked to Parkinson’s disease, may help in diagnosing people sooner and scientists in better understanding the condition.” The researchers wrote, “We identified several blood biomarkers that may be associated with the risk of developing [Parkinson’s disease], providing valuable insights for further exploration of [Parkinson’s disease]-related biomarkers.” They determined that “among the 13 biomarkers, insulin-like growth factor 1 (IGF-1) was associated with an increased risk of Parkinson’s – raising the risk of developing the disease by 25%. Conversely, C-reactive protein (CRP), an inflammation marker, appeared to be protective, decreasing the risk by 11%.” The study was published in npj Parkinson’s Disease.
