I do hope that 3 or 4 times those amounts will correlate to the reduction amount!

Caffeine consumption in older women seems to reduce risk of dementia

A new study suggests a significant relationship between caffeine and dementia prevention, although it stops short of establishing cause and effect.The study, published in the Journals of Gerontology, Series A: Biological Sciences and Medical Sciences, found that higher caffeine intake in women 65 and older was associated with reduced odds of developing dementia or cognitive impairment.

Among the women in the study, self-reported consumption of more than 261 milligrams of caffeine per day was associated with a 36 percent reduction in the risk of dementia over 10 years of follow-up. That level is equivalent to two to three eight-ounce cups of coffee, five to six eight-ounce cups of black tea or seven to eight 12-ounce cans of cola.

“While we can’t make a direct link between higher caffeine consumption and lower incidence of cognitive impairment and dementia, with further study we can better quantify its relationship with cognitive-health outcomes,” said Ira Driscoll, the study’s lead author and a professor of psychology at the University of Wisconsin at Milwaukee.
