The Center for the Biology of Chronic Disease (CBCD) announces an important discovery on the cause of Parkinson’s diseases. The discovery shows how many common latent viruses, which infect the central and peripheral nervous systems, can cause Parkinson’s disease (1). Latent viruses are hidden in the body in a way that most individuals don’t know that they are infected. The discovery was published in the Journal of NeuroVirology.
