Coffee May Ward Off Progression to Dementia

Patients with mild cognitive impairment (MCI) may be able to avoid developing dementia by drinking several cups of coffee a day, the results of a new study suggest.

The study showed that patients with MCI who have a plasma caffeine level of 1200 ng/mL avoided progression to dementia over the following 2 to 4 years.

These patients exhibited a plasma cytokine profile that was exactly the same as that of Alzheimer’s disease (AD) transgenic mice that were given caffeinated coffee and didn’t progress to dementia. It’s therefore very likely that it’s caffeine from coffee, and not from other sources, that affords the cognitive protection, said study senior author Gary W. Arendash, PhD, research scientist, Bay Pines Veterans Affairs Hospital, St. Petersburg, Florida.

The research also suggests that certain cytokine patterns could signal for impending conversion to dementia among those with MCI, said Dr. Arendash. [Read more…]

Study finds drinking coffee can delay onset of Alzheimer’s

A study of senior citizens in Florida found that drinking coffee could delay the onset of or help prevent Alzheimer’s disease.

The study, carried out on adults over the age of 65 in Miami and Tampa, found that those with higher levels of caffeine in their blood avoided the onset of Alzheimer’s in the two- to four-year period they were monitored.

Dr. Chuanhai Cao, a neuroscientist at the University of South Florida College of Pharmacy, said, “These intriguing results suggest that older adults with mild memory impairment who drink moderate levels of coffee — about three cups a day — will not convert to Alzheimer’s disease or at least will experience a substantial delay before converting to Alzheimer’s.” [Read more…]
