Abundant evidence indicates that alcoholism is a complex genetic disease, with variations in a large number of genes affecting risk. Some of these genes have been identified, including two genes of alcohol metabolism, ADH1B and ALDH2, that have the strongest known affects on risk for alcoholism.
Is there a genetic predisposition for alcoholism?
Those who have a family history of alcoholism have a higher risk of developing a drinking problem. Studies show that alcoholism is approximately 50 percent attributable to genetics.
What does biological and genetic research indicate about alcoholism?
Abstract. Substantial scientific evidence has accumulated that both genetic and environmental factors predispose the development of alcoholism in certain individuals. Evidence has accumulated to indicate that alcoholism is a heterogeneous entity arising from multiple etiologies.
What ethnic group has the highest rate of alcoholism?
Native Americans have the highest prevalence (12.1 percent) of heavy drinking (i.e., five or more drinks on the same occasion for 5 or more of the past 30 days; followed by Whites (8.3 percent) and Hispanics (6.1 percent).
Is there a genetic relationship between alcoholism and depression?
These analyses found that the “alcoholism or depression” phenotype showed significant evidence for genetic linkage to an area on chromosome 1. This suggests that a gene or genes on chromosome 1 may predispose some people to alcoholism and others to depression (which may be alcohol induced).
Does a person have to drink everyday to be considered an alcoholic?
Alcoholism affects everyone around you—especially the people closest to you. Your problem is their problem. Myth: I don’t drink every day OR I only drink wine or beer, so I can’t be an alcoholic. Fact: Alcoholism is NOT defined by what you drink, when you drink it, or even how much you drink.

What are some signs that a person may be a problem drinker?
As the effects of alcohol wear off, you may have trouble sleeping, shakiness, irritability, anxiety, depression, restlessness, nausea, or sweating. Alcohol changes your brain chemistry, and when you drink heavily over a long period of time, your brain tries to adapt.

External factors include family, environment, religion, social and cultural norms, age, education, and job status.
What is the heritability of alcoholism?
The heritability of alcohol dependence is estimated to range between 40 and 65%, with no evidence for quantitative or qualitative sex differences in heritability (Kendler et al., 1994; Heath et al., 1997; Prescott and Kendler, 1999; Hansell et al., 2008).
Are Irish more likely to be alcoholics?
It has to do with the fact that Irish people tend to be predisposed to becoming addicted to alcohol because of their genes. According to an article published in Alcohol Research and Health, genes contribute to the development of alcohol dependence with heritability being between 50 to 60 percent for both men and women.
What country has the highest rate of alcoholics?
The top place, with the highest rate of alcoholism, goes to the land-locked country of Belarus. Its citizens drank a total of 14.4 liters or 473 ounces of alcohol annually. Next in line is Lithuania, with 12.9 liters. In third place, leading the Americas, is the island of Grenada, with 11.9 liters.
What profession has the highest alcoholism rate?
As you might expect, food service workers, like servers, bartenders, chefs and restaurant managers, have some of the highest rates of alcohol abuse. The nature of the work provides easy access to large amounts of alcohol and sneaking drinks from behind the bar is pretty common in this field.
What are the four types of drinkers?
