CHICAGO (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.
