Therapies are available to treat Parkinson’s symptoms and improve quality of life for people living with the disease. But we don’t yet have a way to slow or stop Parkinson’s progression, and that is why research is critical. Dr. Tanya Simuni of the Parkinson’s Foundation Center of Excellence at Northwestern University Feinberg School of Medicine says this is an exciting time for the development of Parkinson’s therapeutics. She explains the clinical trials process and describes some ongoing trials, including how the potential new drugs work and why it’s important for people with Parkinson’s to participate in research.
