A cup of Coffee

A cup of coffee a day, or an help reduce the risk of Alzheimer’s disease, the most common form of dementia, new research has suggested. A daily dose of caffeine blocks the disruptive effects of high cholesterol that scientists have linked to the disease, a study in the journal of Neuroinflammation, has revealed.
In the study, researchers at the University of North Dakota School of medicine and health sciences gave rabbits 3 mg of caffeine each day, the equivalent of a daily cup of coffee for an average-seized person. The rabbits were fed a cholesterol enriched diet during this time.
After 12 weeks, a number of laboratory tests showed that the blood brain barrier, which protects the central nervous system from the rest of the body’s circulation, was “significantly” more intact in rabbits receiving a daily dose of caffeine.
Dementia will affect almost one million people by 2020, according to Alzheimer’s society, the leading UK charity dealing with dementia. Every five years after the age of 30, the chances of developing the disease doubles. And, by the time a person reaches so, the odds are one in six.
“This is the best evidence yet that caffeine equivalent to one cup of coffee a day can help protect the brain against cholesterol. It sheds important light on why previous research has shown drinking coffee may reducing the risk of dementia,” Head of research at Alzheimer’s society said.
