There are lots of promising medical study results these days, many of which you never hear about again, but this one seems interesting since many have relatives who have or are at risk of developing Alzheimer's disease. It's also interesting because the "medication" is the caffeine in coffee, and it's great to have a health reason to drink something many of us are addicted to anyway.
"Three large cups of coffee a day could help to slow the progress of Alzheimer’s disease and even reverse the condition, researchers say...mice with a rodent equivalent of the disease showed a 50 percent reduction in levels of amyloid protein in their brains after scientists spiked their drinking water with caffeine...
By the end of the two-month study, the caffeine-drinking mice were performing far better on tests of memory and thinking than mice given water. Their memories were as sharp as those of healthy older mice without dementia."
Something to think about with your morning cup of java.
