A new blood test for Parkinson's disease might mark a significant breakthrough, as researchers say it can predict the disease seven years before any symptoms appear.

Parkinson's disease is a progressive disorder that affects the nervous system which typically starts with tremors and over time affects various aspects such as memory, balance, posture, mobility, and speech. More than 10 million people across the globe live with the condition.
