Coffee drinkers may have another reason to pour that extra cup. When aged mice bred to develop symptoms of Alzheimer’s disease were given caffeine – the equivalent of five cups of coffee a day – their memory impairment was reversed, report University of South Florida researchers at the Florida Alzheimer’s Disease Research Center.
The image above shows that caffeine treatment removed the beta amyloid plaques from the brains of the Alzheimer’s mice.
Back-to-back studies published online today in the Journal of Alzheimer’s Disease, show caffeine significantly decreased abnormal levels of the protein linked to Alzheimer’s disease, both in the brains and in the blood of mice exhibiting symptoms of the disease. Both studies build upon previous research by the Florida ADRC group showing that caffeine in early adulthood prevented the onset of memory problems in mice bred to develop Alzheimer’s symptoms in old age.
