Recent correspondence in the ARCHIVES has highlighted opposing perspectives on advancing gamma knife (GK) radiosurgery for Parkinson disease (PD).1-3 Within that dialogue, the results of our study4 on radiosurgery and localization were cited as supporting evidence in a rebuttal comment by Young2 to a prior article by Okun et al,3 who stated that "a higher complication rate than has been previously appreciated" may result from GK surgery for PD. This statement was based on their observations in 8 patients who were referred to their center for complications of GK surgery for PD.
