The evidence regarding the positive effect of caffeine consumption in the treatment and prevention of Alzheimer’s disease continues to mount with more studies lending support.

Most people are well aware of the stimulating effect that comes with the consumption of caffeine. In fact, with an estimated 80 percent of the population consuming caffeine on a daily basis, it is considered the most commonly used psychoactive drug worldwide.

The consumption of 130 to 300 mg daily is considered a low to moderate intake while consuming 6,000 mg per day is considered to be heavy intake.

This amount of caffeine is equivalent to the amount contained in five 8-ounce cups of coffee.

The researchers noted that after two months on the daily dose of the stimulant, the memory of the mice recovered to the extent of attaining a score on memory tests equivalent to that of normal mice never having shown signs of dementia.

The results of the research team’s studies were published in the July 5th online edition of the Journal of Alzheimer’s Disease.

The studies also revealed that caffeine significantly decreased abnormal levels of the beta amyloid, a protein linked to the characteristic plaque found with Alzheimer’s, in both the brains and the blood of the mice exhibiting symptoms of the disease.

The most common sources of caffeine in the human diet are coffee, tealeaves, cocoa beans, cola, and energy drinks. In addition, it can be produced synthetically and added to food, beverages, supplements, and medications.
