A new research report appearing in the December issue of the FASEB Journal (http://www.fasebj.org) shows how scientists from the United Kingdom have developed a simple blood test to detect Parkinson’s disease even at the earliest stages. The test is possible because scientists found a substance in the blood, called “phosphorylated alpha-synuclein,” which is common in people with Parkinson’s disease, and then developed a way to identify its presence in our blood.
