Dopamine Neuron Cell Replacement Therapy for Parkinson's Disease with Melita Petrossian, MD

Parkinson's disease begins with the quiet loss of the brain cells that make dopamine, and dopamine is what carries your movement, your mood and the drive that gets you through the day. As those cells disappear, so does everything they were holding up, which is why the disease eventually shows itself in so many different ways at once. For years the central question in Parkinson's research has been whether any of that can be given back, and stem cells offer one of the more hopeful answers, since they can be turned into the very dopamine neurons the brain can no longer make on its own.
