Scientists have named 4 sign, which can identify potential alcoholics

The number of people consuming alcohol in recent years has increased significantly. Scientists project that this trend will lead to the fact that by 2030 half the world's population will be drinking drinks with high degrees. However, to identify a predisposition to this is not the most useful habit has become possible thanks to recent research.

Scientists from the University of Glasgow and University of Edinburgh have listed the parameters on which it is possible to identify a potential alcoholic. To the study they have attracted volunteers from 149 countries.

Firstly, people with alcohol dependence often two blood. To this conclusion came in the second half of the last century scientists from the United States. About half of patients drug treatment clinics in the country at that time were such people. Speakers of the fourth group less often than others fell on the treatment or account of a doctor.

The explanation for this can be another carrier of the fourth group of blood is much less so to rely only on these data.

Second, alcoholics often intellectually developed people. There is research data, when volunteers IQ measured at the age of ten. And then after 20 and 30 years, asking how often they abused spirits. It turned out that problems with alcohol are more common for adults, in childhood showed a high level of intelligence.

High intelligence has become one of the key factors. People, from childhood demonstrated greater sophistication, maturity started to increasingly resort to alcohol. Experts explained that this behavior is peculiar to intelligent individuals the propensity for evolutionary new behavior.

Thirdly, with the problem can face people with a calm nature. Scientists conducted tests on rats. The result found that restless and aggressive animals prefer light spirits, and calm their relatives 5-10% solution of ethanol.

According to experts, the love for alcohol can be caused by reduced anxiety, although for a long time it was considered to be the opposite.

Fourth, many alcoholics among the sweet tooth, because of the love for sugar and ethanol meets the same area of the cerebral cortex. It found American nanofizika on the example of the 16 volunteers, average age 26 found out. This means that a sweet tooth could potentially become an alcoholic.
