Is Deep Brain Stimulation Right for You?

So when is the right time to talk to a doctor about deep brain stimulation? "When the medicine isn't working the way it used to, and you are having unpredictable motor function problems, it may be a good time to consider this surgery," Weaver says.

Not everyone with Parkinson's disease will be a candidate. People who have severe mental disability or other medical problems may not be eligible.

Location, Location, Location

Tagliati also says the findings help guide doctors on where in the brain to implant the device.

"Until this study, the decision of location was based on the experience, expertise, and mood of the surgeon or neurologist," he says. For a long time, the belief was that STN was a superior target.

But not according to the findings, Tagliati says. Those people whose device is implanted in the GP region of their brain may maintain thinking and mental faculties longer. "It was as if the disease did not progress as much as in [the] other group," he says.

This target may work better with medication than the other one.

Anyone considering this surgery should ask about the different targets and which makes more sense for them, he says.
