BIOGRAPHICAL SKETCH

Dr. Charles is Associate Professor and Vice-Chairman of Neurology for Education and Development and is Assistant Dean for Admissions at Vanderbilt University School of Medicine. He is the Director of the Neurology Residency Program and the Movement Disorders Clinic and serves as an attending physician at Vanderbilt University Medical Center. His research interests include the treatment of spasticity and cervical dystonia and he is currently leading the only clinical trial approved by the United States Food and Drug Administration to test deep brain stimulation in people with early stage Parkinson’s disease.

Dr. Charles is a member of the American Neurological Association, Fellow of the American Academy of Neurology, Board member of the United Council of Neurologic Subspecialties, and President of the Tennessee Academy of Neurology. He is a member of Alpha Omega Alpha honor medical society and in 2007 received the CANDLE Award. The honor is given to individuals who have devoted themselves to teaching and mentoring. Recipients are nominated and chosen based upon their positive impact on the lives of physicians-in-training, and are recognized by their students as examples of excellence in medical education.

From 1997-98, Dr. Charles served as a Health Policy Fellow in the United States Senate on the staff of the Labor Subcommittee for Public Health and Safety. In 1998 he studied deep brain stimulation for the treatment of movement disorders as a Fulbright Senior Scholar at the Universitaire de Grenoble in Grenoble, France. In 2000 Dr. Charles was a nominee for the United States House of Representatives from Tennessee’s Sixth Congressional District.

Dr. Charles graduated from Vanderbilt University School of Engineering in 1986 with a B.S. cum laude in Computer Science and Mathematics, and earned his medical degree from Vanderbilt University School of Medicine in 1990. He did his internship in the department of Medicine and his residency in the department of Neurology at Vanderbilt. From 1993-94 he was Chief Resident in Neurology, and from 1994-95 he was a Fellow in Movement Disorders and Clinical Neurophysiology at Vanderbilt. In 1996, he completed a Health Care Management course at Vanderbilt’s Owen Graduate School of Management, and in 1997 he completed the Harvard Macy Institute Program for Physician Educators at Harvard Medical School.

RESEARCH SUMMARY

The Treatment of Parkinson's Disease with Deep Brain Stimulation
We are currently conducting a clinical trial testing deep brain stimulation in people with early stage Parkinson’s disease. We are investigating the safety and tolerability of stimulation in early stage disease to hope to better understand if this treatment may slow the progression of the disease in the future.

Treatment of Spasticity in Adults
Spasticity is a condition that is very prevalent in people with intellectual or physical disabilities. The presence of spasticity can often make performance of activities of daily living and care giving very difficult. We are currently investigating the impact of a comprehensive spasticity management program applied to people with disabilities living in long term care settings.

Cervical Dystonia
Cervical dystonia causes painful muscle contractions and abnormal head position. We are investigating the pain relief that people with cervical dystonia experience after neurotoxin injection to the pain relief experienced in people without cervical dystonia.
