Moderate alcohol consumption was associated with reduced risk to get senile dementia and Alzheimer’s disease for people of European descent, according to a paper published in the Journal of Alzheimer’s Disease.

«Our study is unique in that we tracked the changes in the sharpness of mind and memory in older men and women and found that moderate alcohol consumption is associated not only with long life but with a higher chance to stay in a clear mind in old age,» says Linda McEvoy (McEvoy Linda) from the University of California at San Diego (USA).

In recent years, scientists often argue about whether alcohol is dangerous to human health in any quantity, or moderate drinking can lead to favorable outcomes. Over the last three years several groups of biologists have found signs that a wine and other light alcoholic beverages can reduce the probability to get a heart attack or diabetes, and other scholars, on the contrary, said that alcohol is not associated with increased life expectancy, as stated by representatives of the first group of researchers.

McEvoy and her colleagues have found new evidence that moderate alcohol drinking can help the body, not destroy it, watching the health of 1.4 thousand older Americans for 25 years, starting in 1984 and ending in 2009.

Many of the participants these observations, survived until age 85, when many older people are victims of Alzheimer’s disease and other forms of senile dementia, which allowed scientists to estimate how much its development is affected by the consumption of alcohol.

As shown by these observations, the use of relatively small amounts of alcohol, about 100 to 150 milliliters of wine or beer a day was associated with a marked reduction in the risk to get these problems with brain function. Older Americans who drank similar amounts of alcohol, about 2-3 times less likely to suffer from Alzheimer’s disease, and lived longer on average than the typical US resident.

As the scientists, the presence of such a link between alcohol and high resistance of the brain towards the aging does not necessarily prove that alcohol protects nerve cells from Alzheimer’s disease. It is possible that a similar relationship arose from the fact that McEvoy and her colleagues conducted a study in one of the most prosperous areas of California where there are no problems with crime, access to medicine and the «epidemics» of drug abuse and other harmful habits.

«Our findings do not say that you need to start constantly drinking. Many people have other health problems that are only compounded by alcohol and can’t limit yourself to one drink per day. So people wine and beer will not help, and harm,» concludes Erin Richard (Erin Richard), a colleague of McEvoy.
