Our Team
Mark S. LeDoux, MD, PhD


Dr. LeDoux is a clinician-scientist.  He maintains an active basic science lab, and busy clinical practice that includes deep brain stimulation, injections of botulinum toxins, and clinical trials for dystonia, Parkinson disease, spasticity, tardive dyskinesia, and Huntington disease. Dr. LeDoux is internationally-recognized as a leader in patient care and research related to Parkinson disease, dystonia, and other movement disorders. He is a member of the Dystonia Coalition and Parkinson Study Group. Although his lab interests have been focused on neurogenetics and the pathobiology of dystonia, he has used a wide variety of experimental approaches to also study the anatomy and computational organization of motor and autonomic systems, mechanisms of cell death in Parkinson disease, and cell-cycle control in the central nervous system. At present, he serves on the Editorial Boards of Neurology and Tremor and Other Hyperkinetic Movements. Dr. LeDoux has been the author or co-author of more than 150 scientific articles and book chapters, and three books including Movement Disorders: Genetics and Models (Elsevier, ISBN: 9780124051959, 1259 pages).  When not in clinic or the lab, Dr. LeDoux enjoys climbing, fly fishing, and trekking with his kids.
