Researchers have determined that caffeinated coffee fights Alzheimer's disease in mice.

Per the article:


Neither caffeine alone nor a decaf version of the beverage provided the same protection as caffeinated coffee. Researchers found that caffeine interacted with an unknown compound in coffee to increase blood levels of a growth factor called GCSF, which helps create neurons in the brain.


"We are not saying that daily moderate coffee consumption will completely protect people from getting Alzheimer's disease," said lead researcher Chuanhai Cao in a University of South Florida press release. "However, we do believe that moderate coffee consumption can appreciably reduce your risk of this dreaded disease or delay its onset."


Though results have been mixed about coffee's effects on human health, the research contributes to a growing body of evidence showing the beverage may not be that bad after all.

The findings have been published in the Journal of Alzheimer's Disease.

I think you are very right that there could be environmental factors that help bring the disease on but I don't think this invalidates the study especially because it was done under controlled conditions so that the environmental factors would have been the same for all of the groups. I think the study meaningfully suggests that caffeinated coffee may help fight Alzheimer's disease if only in mice and, from reading your take on the study, I think you actually agree with this.

Yes, well coffee is an environmental factor - they have the genes and in study aims to discover more about coffee amongst other environmental factors.  Indeed they have found a link.  I would be worth redoing the test again to check it wasn't a random cluster event and they get the same or similar results.  I've heard that using your brain more is meant to be preventative - and coffee seems to do two things, stimulate digestive function and stimulate brain activity - I always become more chatty and out going if I have coffee - it gives me a high - perhaps that feel good factor has a function also.  But it's great that they do studies about it, so that we can quantify benefits and risks.


Personally though I think that being tested for genes that are a risk, might just cause additional stress that would tip you over the edge.  Perhaps worth a study on it's own.
