Genetic Predisposition To Alcoholism
The role of heredity in disease, alcoholism is very high. The presence of alcoholism among parents is the risk of disease in children at 7 times the risk of dependency in children of healthy parents, which will allow identify children in alkozavisimyh particular risk. It has long been observed that alcoholism usually develops in children whose parents abuse alcohol. According to the research of family alcoholism risk of dependency patients with alcoholism of parents (one or both) to 7 times higher than children of healthy parents. In certain forms of alcoholism, parental likelihood of disease in children up to 88%. Research performed by tracking the fate of children born to parents suffering from alcohol dependence. It turned out that even the education of children in the "healthy" families with a non-drinker adoptive parents and brothers and sisters, the risk of developing alcoholism is 3 times higher than that of nekrovnyh sisters and brothers.
Compared with the non-drinker foster children a large number of drinkers foster children have biological parents – alkozavisimyh. In addition, there is no connection between alcoholism and alcohol abuse adoptive parents of their children, suggesting less influence of the medium. Observations of the twins showed that if one of monozygotic brothers ill from alcoholism, the the other has a 3-fold higher risk of developing the disease than would happen with fraternal twins. Therefore, the influence of genetic factors is not in doubt. However, such observations for single-valued conclusions about the role of heredity is not enough, because with equal bases responsible for the occurrence of alcoholism may be given to environmental factors – education in an atmosphere of drunkenness. Genetics are not children alkozavisimyh as victims, freeing them from liability, and various environmental factors have great importance for the occurrence of alcoholism. Research geneticist, of course, important as the development of prevention treatment, and for specialists who treat alcoholism, to better understand the specifics of the disease.
