People who take drugs that suppress the immune system are less likely to develop Parkinson’s disease, according to a study from Washington University School of Medicine in St. Louis.
The findings, published May 31 in Annals of Clinical and Translational Neurology, suggest that a person’s own immune system helps nudge him or her down the path toward Parkinson’s. Restraining the immune system with drugs potentially could prevent the neurological disorder, which is characterized by tremors, slow movements, stiffness and difficulty walking.
