We would like to clarify several issues concerning the editorial written by Dr Jankovic1 on our article "Complications of Gamma Knife Surgery for Parkinson Disease,"2 both published in the December issue of the ARCHIVES. The gamma knife procedures were not performed at Emory University, as the editorial mistakenly implies, but were done at an outside institution. This was stated clearly in the abstract as well as the "Methods" and "Conclusions" sections. Also, patients were not seen during the 6-month postoperative period, as suggested, but rather at varying times after surgery within an 8-month period. Finally, the editorial criticizes the study for not being controlled, again reflecting the misconception that the patients were part of a clinical trial at our institution.
