Researchers believe that coffee may protect the brain against developing Alzheimer's disease.
According to a recent study, the psychoactive qualities of caffeine might well have an impact on the development of Alzheimer's and Parkinson's diseases and research is currently being undertaken to see how it could be developed into treatments.
"Caffeine is the most widely used psychoactive drug in the world," Gary Arendash, a researcher at the Byrd Alzheimer Institute in Tampa, told USA Today. "We think it might protect against Alzheimer's."
Scientists are hoping to be able to develop medications that can treat not just the symptoms, but the causes of the disease.
The brain stimulants in caffeine appear to slow the process of forgetfulness and confusion which occurs in people suffering from Alzheimer's.
It is suggested that caffeine may actually shield the brain from such problems, but research remains in the early stages.
