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.
The study is published in the June issue of the Journal of Alzheimer’s Disease.
