Drinking three cups of coffee a day can help turn the tide in the fight against Alzheimer's disease in the elderly, is already showing signs of memory problems - these are the conclusions of a new study.According to the study, in people over 65 years, with higher levels of caffeine in the blood of Alzheimer's disease manifested itself into two - four years later than their peers with lower levels of caffeine.Results of the study will be published in the "Journal" Alzheimer's disease "."
Alzheimer's disease is the most common type of dementia in all.Its symptoms include severe memory loss, confusion and mood changes that develop gradually and worsen with age.The new study included 124 people aged 65 - 88 years, with mild cognitive impairment (RBM), which according to medical terminology means moderate memory loss.Each year, approximately 15% of people with RBM develops Alzheimer's disease.
In the study of the levels of caffeine in the blood were more than 50% lower in people with RBM, who during the sur
«Continue to drink coffee," - says the researcher, Ph.D. Chuenhey Cao.He is a South Florida neuroscientist at University College of Pharmacy and Institute named after Alzheimer's in Tampa."There is no apparent reason to reject its use if you have had difficulty with memory.Perhaps it will be the cause of the beginning of coffee consumption by people over 30 years old.Strive to receive an average of three 8-oz cups of coffee a day and always the morning after breakfast.

Coffee may reduce the risk of developing Alzheimer's disease
Accurate data on how the coffee helps to delay the development of Alzheimer's disease is unknown, but Cao has a theory.Coffee interacts with beta-amyloid - a protein which accumulates in the brains of people with Alzheimer's disease."The beta amyloid causes Alzheimer's disease," - he says."We are born with the presence of this protein in our brains."What goes wrong?This protein accumulates and aggregates in the brain, because it is more than sufficient not metabolized in the aging process."Your body can not cope with all this, and unused protein accumulates in the brain."Enter in your daily diet coffee."Caffeine inhibits the production of beta-amyloid, so your body will metabolize exclusively available protein", - says Cao.
do otherwise: there should be an unused protein
Coffee can have other important health benefit.Research has shown that it can reduce the risk of developing Parkinson's, stroke, diabetes type 2 and breast cancer.Sam Gandy, MD, PhD, reviewed the results of the new study.He - the head of research at the Alzheimer's Faculty of Medicine Mount Sinai in New York."We find some support to these observations," - he wrote in an email.
«There are fundamental scientific research of our own and other laboratories showing that a chemical compound called cyclic ATP, can reduce the formation of amyloid, and it is known that caffeine increases the levels of cyclic ATP."
«Besides, attention - a key component of memory, and a well-established fact that caffeine increases attention.Thus, conceivable to believe that caffeine is thereby affecting her, improves memory. "
But Gandy adds that the College of Physicians still stands on the site - that is the question, how and even whether caffeine slows down the development of Alzheimer's disease."Before we can recommend the use of any drug (even caffeine), we must check it in randomized clinical trials.That would be the next obvious step in the history of caffeine.
