November 22, 2011 — Principal investigator Andres M. Lozano, MD, PhD, neurosurgeon at Toronto Western Hospital and professor of neurosurgery at the University of Toronto, Ontario, Canada, said in a release, "To see 62% of the patients in this study respond at 1 year gives us hope that this research may lead to a therapy for this hard-to-treat patient population." The study was published online November 18 in the Journal of Neurosurgery.
"One can envision that this would represent a major milestone in functional neurosurgery and would reinvigorate invasive treatment of behavioral disorders," he writes.
"I believe that we can all agree that if this therapy is to advance and mature, it must be rigorously proven to be both safe and effective. I am confident that Dr. Lozano and colleagues will be at the forefront of this effort."
The study was supported by St. Jude Medical Inc. The study authors disclosed several financial relationships, which are listed in the original article. Dr. Burchiel has disclosed no relevant financial relationships.
