Coffee Improves Memory and Cure Alzheimer

Yahoo News (Monday, July 6 02:34 am) - A few cups of coffee a day may be all that is needed to reverse the effects of Alzheimer's disease, new research suggests.

Scientists have uncovered powerful evidence that caffeine not only helps to stave off the disease but can treat it. They hope soon to follow up the initial results from animal experiments with human patient trials.

US neuroscientist Dr Gary Arendash, who led the research, said: "The new findings provide evidence that caffeine could be a viable 'treatment' for established Alzheimer's disease, and not simply a protective strategy.

"That's important because caffeine is a safe drug for most people. It easily enters the brain, and it appears to directly affect the disease process."

A key aspect of Alzheimer's is sticky clumps of abnormal protein in the brain called beta amyloid plaques. Mice with a rodent equivalent of the disease showed a 50% reduction in levels of amyloid protein in their brains after scientists spiked their drinking water with caffeine. The change was reflected in their behaviour as the mice developed better memories and quicker thinking.

Humans receiving an equivalent dose for their body weight would be consuming 500 milligrams of caffeine - or five eight ounce cups of ordinary coffee - a day.
