(CBS) Is there any way to keep Alzheimer's at bay?
That's the subject of Jean Carper's new book, "100 Simple Things You Can Do to Prevent Alzheimer's." That's also the subject of this week's @katiecouric.
As many as 5.3 million Americans are living with Alzheimer's disease according to the Alzheimer's Association. To date, there is no cure and current treatments have limited effect.
But the story isn't all bleak.
This week's episode of @katiecouric is a discussion about this fatal disease and ways to attempt to prevent memory loss. Carper, a long time health journalist with 24 books under her belt, provides practical tips for improving the strength of your mind, while Couric acknowledges the growing number of caregivers (an estimated 11 million people) who use the Internet for a sense of community, information and support.
According to a survey conduced in September 2010 by the Pew Internet Project and the California Healthcare Foundation, 17 percent of Internet users have looked online for information about memory loss, dementia, or Alzheimer's. (That survey is set for release next month.)
