Delay Alzheimer's by Drinking 3 Cups of Coffee a Day

Love coffee? Here's a compelling reason to keep drinking it.

The Journal of Alzheimer's Disease published a study that demonstrated some significant results related to coffee and cognitive function.

Researchers in Florida measured the amount of caffeine in participants by taking blood samples and testing the caffeine plasma levels. They also tested participants' cognitive functioning at the start of the study and categorized people as fitting into one of three categories:
Normal cognitive functioning- Overall, memory, judgment and decision-making were intact.
Mild Cognitive Impairment- Participants displayed some difficulty in cognitive functioning. Mild cognitive impairment often develops into Alzheimer's disease.
Dementia- The individual displayed clear impairments in cognition such as memory deficits, communication, judgment, etc.
After a period of two to four years, researchers found that a higher level of caffeine plasma (greater than 1200 ng/ml) was correlated with the following results:

Stable cognitive functioning (no cognitive decline) was maintained in those who began the study with normal cognition.
A lack of progression to dementia occurred in the participants who began the study in the mild cognitive impairment (MCI) category. This is especially notable because there is usually a high rate of progression from MCI to dementia.
Additionally, a higher rate of progression from mild cognitive impairment to dementia was seen in participants whose caffeine intake was lower.
