This Sunday, July 8, 2012 photo shows Jason and Karin Marder in their home in New York. Jason Marder, who turned 70 on Tuesday, July 10, 2012, was diagnosed with Alzheimer's more than eight years ago. In the roughly five years that her husband has taken Gammagard, "there has been decline" in his health but it is very minimal and the kind of slowing down you might expect from ordinary aging, she said. "He travels the subways, he does things that you and I do. And our quality of life together is what's most important." For the first time, researchers are reporting that a treatment might help stabilize Alzheimer's disease for as much as three years, but the evidence is weak and only in four patients, including Jason Marder. The results were discussed Tuesday, July 17, 2012 at an Alzheimer's conference in Vancouver, British Columbia, Canada. (AP Photo/Seth Wenig)
