Brain pacemaker helps Parkinson's, but with risks (AP)

Sharon Pederson poses for a photograph at a friend's house in Petaluma, Calif., Monday, Jan. 5, 2009. Pederson is a study subject who got deep brain stimulation, or DBS, surgery for her Parkinson's disease. In DBS, a surgeon implants electrodes in the brain which are then connected to a pacemaker-like device that can be adjusted and turned off and on. The device sends tiny electrical pulses to the brain, disabling overactive nerve cells. (AP Photo/Jeff Chiu)AP - Parkinson's sufferers who had electrodes implanted in their brains improved substantially more than those who took only medicine, according to the biggest test yet of deep brain stimulation. The study, which followed patients for six months, offers the most hopeful news to date for Parkinson's sufferers. The new technique reduced tremors, rigidity and flailing of the limbs and allowed people to move freely for nearly five extra hours a day.
