Did you know? ©Flip Schulke “We’re focused on areas that may have a real payoff in terms of new drugs and surgeries, and that payoff could come relatively soon,” explains DeLong. “Better understanding of the mechanisms behind a disease gives you a better understanding of opportunities to improve treatment.” Putting this theory into practice, Emory has pioneered new surgical therapies, including pallidotomy and deep-brain stimulation. With deep-brain stimulation, an implanted electrical device works like a pacemaker, stimulating the brain to function more normally. With pallidotomy, surgeons destroy misfiring cells with a heated probe guided by precise measurements of brain activity. Both techniques reduce symptoms dramatically. For patients with advanced PD, Emory researchers are studying Spheramine, a tiny capsule loaded with retinal cells. When implanted in the brain, these cells trigger dopamine production. Patients in a current Spheramine study have improved up to 50% after treatment. Emory is involved in 30 clinical trials of new drugs as well as many clinical and laboratory studies of Parkinson’s and other movement disorders, says Stewart Factor, who directs Emory’s Movement Disorders Program and is a leading researcher in the field. “Parkinson’s disease research advances are moving at an incredible “Emory has one of the leading programs for Parkinson’s disease in the world.” — Allan Levey, Chair, Department of Neurology, Emory School of Medicine (which causes repetitive face movements and rapid eye blinking), Emory also specializes in diagnosing and treating these movement-related conditions: Ataxia: Emory’s Ataxia Center specializes in diagnosis and comprehensive care for patients with ataxia, a loss of Emory treats these movement disorders muscle coordination.

How you can help Plant a seed: A gift of “seed money” can help develop a promising new idea to the point where major funding sources like the National Institutes of Health will provide millions more dollars in support. Endow a chair: A gift to sponsor a chair helps attract the world’s best researchers and ensure they have the resources needed to do their work. Fund a fellowship: Fellowship gifts support talented postdoctoral researchers as they find new ways to diagnose and treat movement disorders. Volunteer for a clinical trial: Trials require large numbers of patients wanting state-of-theart care and the chance to help improve diagnosis and treatment for everyone. Ask your doctor how to volunteer.
