Inside Tract: Can deep brain stimulation survive its reputation for success?

When she was 37, Clare developed a tremor down her left side. At 39, she was diagnosed with Parkinson´s disease and put on a series of medications. These helped for a time, but the effect didn´t last. Within a few years, her tremors had grown so severe that Clare was dropping food at her waitressing job. She couldn´t seat guests, and she burned herself when she tried to help out in the kitchen. Increasingly unable to support herself and at a loss for other options, Clare began to look into something called deep brain stimulation (DBS).
