Could a Blood Test Predict Parkinson's Years Before Symptoms?

A new blood test might be able to predict Parkinson's disease up to seven years before symptoms of the movement disorder surface, researchers said.

“As new therapies become available to treat Parkinson's, we need to diagnose patients before they have developed the symptoms,” said senior researcher Kevin Mills, a professor with University College London. “We cannot regrow our brain cells and therefore we need to protect those that we have,” Mills said in a university news release. “At present, we are shutting the stable door after the horse has bolted and we need to start experimental treatments before patients develop symptoms.”

Researchers had the AI analyze blood from 72 patients with Rapid Eye Movement Behavior Disorder. The disorder causes people to physically act out their dreams without knowing about it or remembering it.
