Early Parkinson’s could be detected decades before symptoms with simple blood test

A new study from Chalmers University of Technology in Sweden, along with Oslo University Hospital in Norway, may have discovered a way to detect biomarkers of Parkinson’s disease in the blood up to decades earlier.

In the very early stages of the disease, the body goes through changes related to DNA repair and stress in cells. These changes leave detectable clues in the blood before major brain damage occurs, according to a press release for the study.

This could allow for early detection of Parkinson's...
