One neurologist sees potential problems with this procedure. The chief disadvantage is the risk of bleeding in the brain, Joseph Jankovic, MD, tells WebMD. He is director of the Parkinson's Disease Center at Baylor College of Medicine in Houston.

"Given a choice, I would still prefer the deep-brain stimulating procedure. In our center, we have a great deal of experience with it and have not yet had serious complications in well over a hundred patients," says Jankovic.

"Intuitively, it makes sense that patients might [bleed] because you're destroying tissue," Juncos tells WebMD. But even with deep-brain stimulation, some patients have [bleeding] because the brain is being probed, he adds.

"Surgery carries some risk, no matter how you do it," says Juncos. "Even if the patient [bleeds], generally [bleeding] is not large. Fortunately, by and large, patients recuperate and retain the benefit."
