Parkinson's research needs private donations
Japanese scientists have developed a new blood test that can detect Parkinson's with high accuracy.
The test works by detecting a specific protein called α-synuclein that is misfolded in these diseases.
Previous tests could also detect this protein, but they required an invasive method that involved taking a sample from the spinal cord (cerebrospinal fluid). This new test can detect the protein directly in the blood, making it much easier and less invasive.
