Abstract
Repetitive behavior has been increasingly reported in Parkinson's disease (PD) patients. This study evaluates the effect of Deep Brain Stimulation (DBS) treatment on existing repetitive behavior in three PD patients who underwent unilateral STN DBS surgery at the University of Florida Movement Disorders Center. No significant change in repetitive behavior was noted acutely post-surgery; however, all cases were participating less in their repetitive behavior over time. In this series, DBS surgery seemed to have no acute effect on repetitive behavior. It is difficult to ascertain whether DBS improves repetitive behavior chronically because of confounding factors in our three cases.
