Coffee ‘may reverse Alzheimer’s’ (In Mice!)

From BBC Health News, July 5, 2009

Coffee ‘may reverse Alzheimer’s’

A possible treatment for dementia?

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.

Previous research has also suggested a protective effect from caffeine.

But British experts said the Journal of Alzheimer’s disease study did not mean that dementia patients should start using caffeine supplements.

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.

  2. I’d have no problem drinking five cups of coffee in a day, but I’d never sleep again. How good is that for brain function?

    I could take sleeping pills, but what would they do to my brain if taken every night?

    Sigh. Let’s hope I never have to worry about this issue!

    And let’s hope they come up with something that really cures or prevents A;zheimer’s!

  4. LLOOOLLL, Geek, great minds run in the same direction, eh?

    LLOOLL – I think a “cup” is defined as like 6 oz. Footloose! You’re right, until you got used to the dosage, you could be pretty wired!

    Ahmed, nice to see you again. :-) I hope so, too. I think all these reports are small hints to the bigger picture.
