Bill Gates' Newest Mission: Curing Alzheimer's

Currently, there is no treatment to stop the disease, let alone slow its progression. And billionaire Bill Gates thinks he will change that. It's one of the holy grails of science: a cure for Alzheimer's."I believe there is a solution," he told me without hesitation.
"Any type of treatment would be a huge advance from where we are today," he said, but "the long-term goal has got to be cure."
I had the chance to sit down with Gates recently to talk about his newest initiative. He sat in front of our cameras exclusively to tell me how he hopes to find a cure to a disease that now steals the memories and other cognitive functions of 47 million people around the world.
