Survey finding that "even an appropriate amount of sake" accelerates the decline of the cognitive function of the brain

Although it is common sense in the world that "excessive drinking is bad for health, moderate drinking is good for health", in the study of the UK, "The more alcohol intake, the lower the cognitive function of the brain, even if a proper amount of drinking alcohol There is no difference in reducing the function of the brain even if it is, "a cruel investigation report has been made for alcoholic drink.

Even moderate drinking may speed brain decline

Research teams such as Dr. Ana Topiwala et al. Investigated "degree of influence of drinking amount on brain functions" by using a research report that tracked the health status of employees in the long term for civil servants in the UK and London. The report is a report of alcohol intake every week by 550 persons with an average age of 43 years over a long period of 30 years from 1985 to 2015. This report and 550 subjects who are subjects are evaluated by MRI for brain functions , The influence of alcohol intake on brain function is measured from the measurement result.

In the survey, more than 30 cups a week, people who drink alcohol 5.8 times as much as those who do not drink alcoholHippocampusTurned out to be atrophied easily. Since Kaiba controls memories and cognitions, it was found that cognitive function of the brain is easy to decline for people who consume alcohol well in the long term.

It was also found that the more intake of alcohol, the easier the atrophy of the hippocampus is, but it was also found that those who kept moderate alcohol consumption can not escape hippocampal atrophy. The dogma that "moderate drinking is good for health" means that it is understood that it does not hold for the brain. The rate of shrinkage of hippocampus by 1 year of aging is 0.02%, while drinking excessively once a week corresponds to raising the atrophy rate by 0.01%, so the person who drinks in an appropriate amount The brain's hippocampus is atrophied so much that even if it agrees with aging.


In addition, in this survey, the result of the hippocampus change is statistically significant only in the right part, there is no difference in the hippocampus in the left part, and the researcher can not explain the cause well Hmm.

For the results of this research, it is a result obtained from a very limited subject "to 550 public officials living in moderate educated middle-class education in London" and the statistical value is small Although it is also possible to see, psychiatrist Killian Welch points out that there is the possibility of changing the level of 'healthy drinking'.
