High coffee consumption could ward off Alzheimer’s, say USF researchers

I’m drinking coffee as I write this. And when I’m done with this cup, I plan to drink another, and another.

USF reported this week that its researchers have more evidence that people who drink coffee are less likely to develop dementia.

They published their findings yesterday in the Journal of Alzheimer’s Disease.

For more than five years, USF’s Chuanhai Cao and Gary Arendash have been studying caffeine consumption as a way to ward off Alzheimer’s disease.

They showed that it helped mice that had been bred to get the disease. Then last year they reported that caffeine interacts somehow with a substance in coffee that boosts an Alzheimer’s fighting substance in the blood.

With this latest study they worked with University of Miami researchers to follow 124 actual human coffee drinkers in Tampa and Miami, focusing on people with mild memory loss.

They found that the subjects who had a lot of caffeine in their blood did not develop full-blown Alzheimer’s in the two-to-four-year follow up period. Those who did get worse, however, had lower blood caffeine levels.

“Caffeine and coffee appear to directly attack the Alzheimer’s disease process,” Arendash said in a USF Health news story.

They’re not sure why it works and they’re quick to say they need to do more research with a bigger group of people, but in the meantime, drink up. No prescription needed, at least until bedtime comes.
