The new blood test for Parkinson's is a genuine thing but at least ten years from testing to use. It is 80% accurate so far in confirming diagnosis but needs time to confirm early Parkinson's in people with the potential to develop the disease. Dr Kay Double and her colleagues also want to come up with some neuroprotective drug when confirming early diagnosis. There seems little advantage in confirming a diagnosis ten years before the symptoms show and offering no help.
