A new reason to reach for that morning cup of coffee:  Researchers have now discovered a link between caffeinated coffee and Alzheimer's prevention.

The important ingredient, though is caffeine.

What’s really interesting is that caffeinated coffee -- but not decaf -- boosted the production of GCSF.

For the new study, Arendash and his colleagues “treated” healthy mice and Alzheimer’s mice with either caffeinated or decaffeinated coffee. Then the researchers ran a test to see if either beverage led to better memories.
