Nearly 7 million Americans are living with Alzheimer’s disease. By 2050, this number is projected to rise to nearly 13 million.  For years, research into the disease remained underfunded -- and patients who received a diagnosis had few options when it came to treatment. But in recent years, that has begun to change.  “There are exciting developments in the research field at each stage of our lives that affect the strength of our brain and the ability of the brain to resist brain challenges,” says George Vradenburg. Vradenburg is chairman of the non-profit UsAgainstAlzheimer's, which he co-founded in 2010 with his late wife, Trish. He joins Diane for a conversation about his hopes and fears for Alzheimer’s research, and how the Trump administration could change those.
