Researchers at Bonn university in North Rhine-Westphalia and Lille University in France found that caffeine-like substance help limit the creation of Tau protein, which is seen in higher amounts in people with Alzheimer's.
Tau proteins are considered one of the first markers of developing the disease, along with beta amyloid proteins – which have already been found to respond well to caffeine.
The team initially tested their theory on mice and are now gearing up to move onto bigger animals.
Scientists Christa Müller and her Lille colleague David Blum confirmed on Monday their findings, which will be published in online magazine “Neurobiology of Ageing.” Both said that it would be wise to exercise patience while waiting for the next step.
The former president of the German Association for Gerontology and Geriatrics Werner Hofmann, spoke of the study's “promising statement”. But he had added that finding a cure fo Alzheimer's was "still a long way off".
