Described as a “big step forward” for research and treatment of Parkinson’s disease, new research from Mayo Clinic in Arizona and Banner Sun Health Research Institute suggests that testing a portion of a person’s saliva gland may be a way to diagnose the disease. The study was released today and will be presented at the American Academy of Neurology’s 65th Annual Meeting in San Diego, March 16–23.
“There is currently no diagnostic test for Parkinson’s disease,” says study author Charles Adler, M.D., Ph.D., a neurologist with Mayo Clinic in Arizona. “We have previously shown in autopsies of Parkinson’s patients that the abnormal proteins associated with Parkinson’s are consistently found in the submandibular saliva glands, found under the lower jaw. This is the first study demonstrating the value of testing a portion of the saliva gland to diagnose a living person with Parkinson’s disease. Making a diagnosis in living patients is a big step forward in our effort to understand and better treat patients.”
