New method may identify younger people at risk for Parkinson’s

A new method for detecting toxic alpha-synuclein protein clumps in skin cells could help diagnose Parkinson’s disease up to 20 years before motor symptoms appear. The technique uses super-resolution microscopy and advanced computational analysis to map these protein clumps. According to lead researcher Uri Ashery, PhD, this tool may enable earlier diagnosis and prevention of further cell damage. The study, published in Frontiers in Molecular Neuroscience, found that alpha-synuclein aggregates start forming about 15 years before symptoms arise, leading to neuron death that worsens five to ten years before diagnosis. By detecting these aggregates early, the researchers hope to slow or stop the disease's progression. The research showed that Parkinson’s patients had more, larger, and denser alpha-synuclein aggregates in their skin samples compared to healthy controls. The Michael J. Fox Foundation is supporting further studies on this method with a larger sample size. Researchers plan to expand their findings using machine learning, targeting individuals with genetic mutations linked to Parkinson’s.
