Blood Test Aims to Detect Parkinson's in Early Stages
One goal is to "greatly" improve the accuracy of Parkinson's diagnosis through a combination of analysis of symptoms, brain scans and blood tests, Potashkin said. It would also help to diagnose Parkinson's in early stages and use blood tests to check its progress and see if drugs work early on, she said.
A blood test to diagnose Parkinson's would conceivably be "much less expensive and more easily accessible" than brain scans, said Julie Andersen, a professor at Buck Institute for Research on Aging in Novato, Calif.
