Caffeine & Alzheimers

Something already common in our every day lives is reversing the effects of Alzheimers in mice? It seems an entirely exciting prospect to me. I'm anxious to see the human trials completed.


Link to the full BBC news article.

Coffee 'may reverse Alzheimer's'
Drinking five cups of coffee a day could reverse memory problems seen in Alzheimer's disease, US scientists say.

The Florida research, carried out on mice, also suggested caffeine hampered the production of the protein plaques which are the hallmark of the disease.

“ The results are particularly exciting in that a reversal of pre-existing memory impairment is more difficult to achieve ”

The 55 mice used in the University of South Florida study had been bred to develop symptoms of Alzheimer's disease.

First the researchers used behavioural tests to confirm the mice were exhibiting signs of memory impairment when they were aged 18 to 19 months, the equivalent to humans being about 70.

Then they gave half the mice caffeine in their drinking water. The rest were given plain water.

The mice were given the equivalent of five 8 oz (227 grams) cups of coffee a day - about 500 milligrams of caffeine.

The researchers say this is the same as is found in two cups of "specialty" coffees such as lattes or cappuccinos from coffee shops, 14 cups of tea, or 20 soft drinks.

When the mice were tested again after two months, those who were given the caffeine performed much better on tests measuring their memory and thinking skills and performed as well as mice of the same age without dementia.

Those drinking plain water continued to do poorly on the tests.

In addition, the brains of the mice given caffeine showed nearly a 50% reduction in levels of the beta amyloid protein, which forms destructive clumps in the brains of dementia patients.

Further tests suggested caffeine affects the production of both the enzymes needed to produce beta amyloid.

The researchers also suggest that caffeine suppresses inflammatory changes in the brain that lead to an overabundance of the protein.

Earlier research by the same team had shown younger mice, who had also been bred to develop Alzheimer's but who were given caffeine in their early adulthood, were protected against the onset of memory problems.

...
My maternal grandmother was tormented by an especially bad case of Alzheimers the last eight years of her life. I have always been interested in research on the subject. I know that I am at risk of the disease, and would like to do everything I can to delay its onset. If incorporating a mild amount of caffeine into my diet in my early 20's might help, I'm going to give it a try.

How does this preliminary study impact you?
Would you recommend coffee to a relative experiencing the early stages of Alzheimers in the hopes that it will reverse or decrease their problems with Dimentia?
