At the University of Florida, Parkinson’s disease patient Russell Price undergoes surgery to implant a deep brain stimulation (DBS) lead that will deliver electrical impulses to motion-controlling parts of his brain, treatment which has been shown to provide substantial relief from symptoms in appropriately selected patients. Additional improvement in some patients may also derive from the mere expectation that the procedure will help—the so-called placebo effect. “It’s not a magical thing,” says neurologist Michael Okun. “It’s another part of the brain that is producing a beneficial effect not directly related to the action of our treatment.” ➡ Subscribe: http://bit.ly/NatGeoSubscribe
