Richardson, III, M.D. ResearchMayo Clinic doctors trained in nervous system conditions (neurologists) and other specialties conduct extensive research in genetics, causes, new diagnostic tests, and treatments for Parkinson's disease and other movement disorders. For example, Mayo researchers have found that testing a person's saliva gland may be helpful in confirming a diagnosis of Parkinson's disease, and as a tool for researchers to understand how Parkinson's disease develops. Mayo Clinic doctors have also identified many genes associated with Parkinson's disease, as well as many risk factors for the disease through epidemiologic studies. Doctors study potential causes and possible treatments for Parkinson's disease. Doctors also conduct research in deep brain stimulation to treat Parkinson's disease and other movement disorders. You may have the opportunity to participate in research studies or clinical trials.
