The Role Genetics Play In Alcoholism

For example, both genetics and lifestyle factors—such as diet, physical activity, and stress—affect high blood pressure risk. NIDA research has led to discoveries about how a person’s surroundings affect drug use in particular. The heavy drinking that often occurs in alcohol use disorder, and can also occur in short-term episodes called binge drinking, can lead to a life-threatening overdose known as alcohol poisoning. Alcohol poisoning occurs when a large quantity of alcohol consumed over a short time causes problems with breathing, heart rate, body temperature, and the gag reflex. Coma, brain damage, and death can occur if alcohol poisoning is not treated immediately. Alcohol use disorder is a broad diagnosis that encompasses several commonly used terms describing problems with drinking. It includes alcoholism, also called alcohol addiction, which is a long-lasting condition characterized by a powerful, compulsive urge to drink alcohol and the inability to stop drinking after starting.

Sharing developmentally appropriate information and education about the dangers of alcohol use and your family history. In such an instance — where overindulging quickly becomes overly unpleasant — genetics may play a key role in whether someone can or can’t easily stop drinking. Those stories about scientists discovering a gene that explains Uncle Gene’s drinking problems, there may be nuggets of truth to them. To say, however, that there is one lonely gene responsible for alcohol abuse — that’s bunk. Genes may also play a role in the effectiveness of the drug naltrexone, used to prevent relapse to drinking among people who misuse alcohol. There are other factors, but researchers say certain genes make drinking a pleasant or unpleasant experience. Long-term alcohol abuse can result in several medical conditions.

Is Alcoholism Inherited?

Binge drinkers can suffer blackouts when drunk without being alcoholics. Some types of cancer and injuries common to alcoholics are also common in those who binge drink.

However, scientists also argue that genetics play a significant role in the risk of developing alcoholism and the likelihood of hereditary effects. It is likely that, as for most complex diseases, alcohol dependence and AUDs are due to variations in hundreds of genes, interacting with different social environments. An additional challenge in the search for genetic variants that affect the alcoholism genetic statistics risk for AUDs is that there is extensive clinical heterogeneity among those meeting criteria. Because the diagnosis of an AUD requires the presence of a set of symptoms from a checklist, there are many different ways one could meet the criteria. There are 35 different ways one could pick 3 criteria from 7 (DSM-IV alcohol dependence) and 330 ways to pick 4 from 11 (DSM-5 severe AUD).

Is Alcohol Addiction Genetic?

Hereditary and genetic factors make up about 50-75% of the causes of substance abuse and addiction. If someone has certain genes or hereditary influences, they may be more likely to display addictive behaviors. There are several things you can do to minimize your potential risk of developing alcoholism, especially if it runs in your family.

It is estimated that while there are over a dozen genes that contribute to a tendency towards alcohol abuse, each on its own shows a limited correlation to alcoholism without environmental stressors. Therefore, the more genes present, the higher the likelihood is of developing AUD, and thus we can infer that genetics do play some role.

Gene variations that result in skin flushing, nausea, headaches, and rapid heartbeat when drinking alcohol discourage its consumption and reduce the risk of alcohol use disorder. Populations effects of alcohol that have a higher prevalence of such gene variations, such as people of Asian or Jewish descent, tend to have a lower risk of alcohol use disorder than other populations.

In order to overcome these issues, each one should be treated separately by a medical specialist. Describe alcohol addiction, including potential genetic and environmental factors leading to addiction. While some genes are linked specifically to alcohol addiction, other genetic factors may be linked to addiction in general. Having a genetic predisposition to addiction in general can lead to cross-addiction. Mental Illnesses alone increase the frequency of alcohol use disorders. Furthermore, their genetic makeup when combined with other genes has been shown to increase the chances of AUD as well. Mental illness is only one example of genetic variants that are shown to increase alcoholism risk.

Why Is Alcoholism Hereditary?

As noted above, the functional ADH1B polymorphism is not represented on GWAS platforms; GABA-receptor genes are often nominally significant but well below genome-wide significance in these studies. Thus, the genes and SNPs found through GWAS have had little overlap with previous findings based on candidate genes/pathways and linkage analyses. Looking at adoptees, for example, if their biological parents were alcoholics, they may be more likely to abuse alcohol, but it’s not a given. With twins, too, it seems genetics plays a strong role in alcohol abuse. Lab rats and mice bred to choose alcohol and bred to have a more painful withdrawal to intoxicants reinforce the idea that alcoholic traits are rooted in genetics.

When a partner or close friend frequently drinks, you may be more inclined to join them. Giving into peer pressure can lead to drinking problems down the road, as well as many health complications that arise from excessive alcohol consumption. Rather than feel the need to drink, offer to be designated driver. Drinking in an effort to reduce stress can quickly turn problematic. Career paths that are more likely to face high levels of stress due to long hours and strenuous tasks include doctors, nurses, emergency rescue workers, construction workers and military.

Other Causes Of Alcoholism

Among those abusing alcohol, people who are genetically predisposed to alcoholism have a higher risk of developing an alcohol use disorder. Although people can inherit alcoholic tendencies, the development of an alcohol use disorder is also dependent on social and environmental factors.

Some of these changes can be passed on to later generations. Habitual excessive use of alcohol changes the chemistry of the brain and leads to tolerance, which means that over time the amount of alcohol ingested needs to be increased to achieve the same effect. In severe cases, agitation, fever, seizures, and hallucinations can occur; this pattern of severe withdrawal symptoms is called delirium tremens. Alcohol use disorder is a diagnosis made when an individual has severe problems related to drinking alcohol. People with maladaptive family dynamics are more likely to abuse substances.

Whole Person Healing For Recovery From Alcoholism

The American Association for Cancer Research publishes that the Research Council on Problems of Alcohol was established to try and figure out a scientific link for the effects of alcohol on humans. Jellinek was the executive director and became the first director of the Center of Alcohol Studies at Yale in the early 1940s. Jellinek was instrumental in establishing alcoholism as a disease with scientific considerations, per the Journal of Studies on Alcohol and Drugs.

  • As a rule of thumb, a person increases their risk of addiction to alcohol if they regularly consume a high volume of this drug.
  • This is what makes it difficult for heavy drinkers to quit and can cause uncomfortable withdrawal symptoms.
  • Some of the genes identified through this approach have been replicated across a number of studies and appear to be robust genetic findings.
  • Unfortunately, alcohol may initially relieve the symptoms, but in time, alcohol will make them worse.

But, this factor depends on how close the relatives are to each other. One parent struggling with alcoholism can increase a child’s risk by 3 to 4 times. The long arm of Chromosome 7 contains the acetylcholine receptor gene CHRM2 . The journal Genes, Brain and Behavior publishes that this gene has been linked to a heightened risk of alcoholism.

What Causes Alcohol Addiction?

Genetics influence a person’s likelihood of developing AUD, but it isn’t the only factor. Many people have family members with AUD who do not develop the disorder. However, it could also mean that people with close relatives who abuse alcohol grew up in an alcohol-centric environment. A person’s environment will ultimately influence how his or her inherited genes are expressed. Varied Serotonin Levels — Abnormal levels of serotonin in the brain have been linked to a genetic predisposition to alcoholism. Research is proving that alcoholism is a complex genetic disease, and there are many genes that affect its risks. For example, the ADH1B and ALDH2 genes have been shown to have strong effects on alcoholism risks.
