Caffeine could play a role in Alzheimer's care

Alzheimer's care may benefit from further research into the effects of caffeine on reversing some symptoms of cognitive decline, a new study suggests.

Scientists at the University of South Florida have been working with the stimulant in animal models of the neurological condition, and say that frequent doses were able to limit the levels of a protein linked with Alzheimer's disease.

When given the equivalent of five cups of coffee, the subjects were able to significantly lower the number of proteins linked to memory problems.

Compared to those who were only given water, the subjects were able to do better on tests compared to their peers, with a comparable human age of 70, as those with Alzheimer's disease who were given caffeine were able to perform as well as their peers without the affliction.

While previous research has found that the chemical could provide protection against the disease, lead author Dr Gary Arendash says the new data supports clinical trials that could further cement his teams' findings.

"Caffeine is a safe drug for most people, it easily enters the brain, and it appears to directly affect the disease process," he added.
