Coffee is certainly one of science's most investigated beverages.

Recently, I found the Lifehacker website stating:

According to further research, regular coffee drinkers may have less of a risk for developing Alzheimer’s disease in later life – by as much as 60%!

However, for another claim on the same page, it cites the "British Coffee Association". I do not accept that as a credible source. For that specific claim, above, we only get "According to further research" without any source.

Is there any scientific evidence supporting that claim?
