The clinical program for Movement Disorders was established to provide state-of-the-art treatment for Parkinson's disease and other involuntary movement disorders, to educate students, residents and community physicians in this field, and to develop an active clinical research program. Dr. Dewey trained in neurology and movement disorders at the Mayo Clinic in Rochester, Minnesota and established the clinical program upon joining the neurology faculty in 1994. Dr. O'Suilleabhain joined the effort in 1998 upon completion of his residency and movement disorders fellowship which were also conducted at the Mayo Clinic.

Drs. Dewey and O’Suilleabhain have developed an active clinical practice seeing patients with Parkinson’s disease, Huntington’s disease, tic disorders, tremor disorders, dystonia and a host of other unusual movement disorders. They also work closely with Dr. Cole Giller, an associate professor in the department of neurosurgery, treating patients with Parkinson’s disease and essential tremor who undergo ablative procedures or deep brain stimulator implantation for medication-refractory symptoms. Since the program’s inception, over 3000 patients have been evaluated and treated in the clinical program for Movement Disorders.
