Environmental influences are other components that can lead to alcohol addiction, either singularly or as they interact with other factors. These can be related to childhood or upbringing, family environment, social situations, or with a significant other. First, there may be something about identical twin males, genetically speaking, that makes them more likely to express an alcohol use disorder if one twin has one as compared to females (50 percent versus 30 percent). As researchers have noted, other genes (beyond the cluster that NIDA found) can play a role in the development of an alcohol use disorder. Second, if an identical twin has a sister or brother who has an alcohol use disorder, the odds are not that they will also develop one.

Washington University School of Medicine’s 1,500 faculty physicians also are the medical staff of Barnes-Jewish and St. Louis Children’s hospitals. The School of Medicine is a leader in medical research, teaching and patient care, ranking among the top 10 medical schools in the nation by U.S. Through its affiliations with Barnes-Jewish and St. Louis Children’s hospitals, the School of Medicine is linked to BJC HealthCare.

  • Any 4 to 5 symptoms are considered moderate and 6 or more are considered severe.
  • This brain chemical that’s widely thought to be involved in alcohol dependence.
  • And if you have no genes for alcoholism whatsoever, you aren’t totally off the hook.
  • Growing up around alcohol alone will not cause an individual to develop an alcohol use disorder, and it can increase the chance of engaging in alcohol use that could sow the seeds of progressive alcoholism.
  • Similarly, while there is a genetic component to alcohol tolerance, there have been largely inconclusive results about an alcohol dependence gene being hereditary.
  • Environmental, behavioral, and social aspects are thought to account for the other half.

The topic of genetics and an alcohol use disorder only underlines the complexity of alcohol abuse. No one is immune from the risk of developing an alcohol use disorder. As a rule of thumb, a person increases their risk of addiction to alcohol if they regularly consume a high volume of this drug. For this reason, there is a general advisement that individuals “drink responsibly,” which means keeping intake to a manageable level. To use a legal standard, individuals could feasibly enjoy alcohol while being mindful to constantly keep their blood alcohol content (BAC) to below 0.08 percent. In other words, individuals are considered legally too drunk to drive if their BAC is 0.08 percent or higher.

Environmental factors, personal metabolism and biological aspects, and social influences can all contribute to the development of the disorder. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) publishes that about 16 million Americans struggle with an alcohol use disorder (AUD). Alcohol is one of the most commonly consumed psychoactive substances in the world. It is, however, an addictive substance, and problematic use can lead to both alcohol dependence and the onset of alcoholism.

difficulties of genetic studies are compounded by environmental heterogeneity in

access to alcohol and social norms related to drinking. People with a family history of alcoholism have the highest risk of struggling with alcohol use. However, environmental and social factors can increase or reduce this genetic risk. Genetics help determine our traits, behaviors and personality characteristics. As a result, it’s possible for families with a history of alcoholism to pass down those tendencies to later generations. Genetics, as well as social and environmental factors, strongly influence alcohol dependency.

Will I Become an Alcoholic If My Parents Are?

There are also behavioral genes passed down that could influence a propensity for alcoholism. Mental illnesses, such as depression and schizophrenia, are more common in people with a family history of these disorders. People with mental illness have a higher risk of turning to substance abuse as a way of coping.

If you are in doubt, here we can help you answer some questions and find out if you need to start your recovery journey. Whole person healing is important for ending the cycle of addiction that you are stuck in right now. Trauma, dual diagnosis, and underlying conditions feed alcoholism and the alcoholism feeds those problems, in return. So while there may never be a magic bullet to cure alcoholism, Dr. Karpyak says genetic research is making it easier for health care providers to give the most effective treatment possible to each patient. Hugo Bellen, a geneticist at Baylor College of Medicine in Houston, Texas, said the study “lays the foundation for a genetic approach to dissecting the acute, and possibly the chronic, effects” of alcohol in people.

Scientists have even identified several genes that they believe influence alcohol addiction. The most obvious of these are the genes that cause “alcohol flush reaction”—most common in people of Asian descent. It makes sense that a person with an allergic reaction to alcohol would be less likely to abuse it. But several other genes also appear to make a difference, in more subtle ways. Other studies on children of alcoholics have found links between having an alcoholic parent, and problems like depression, anxiety, and low self-esteem. Laws prohibit use below a certain age, which helps prevent young people from drinking.

Genetic vs. Hereditary Alcoholism


(alcohol dependence, alcohol use disorders) is a maladaptive pattern of

excessive drinking leading to serious problems. 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 eco sober house cost have the strongest known affects on risk for alcoholism. Studies are

revealing other genes in which variants impact risk for alcoholism or related

traits, including GABRA2, CHRM2,

KCNJ6, and AUTS2. As larger samples are

assembled and more variants analyzed, a much fuller picture of the many genes

and pathways that impact risk will be discovered.

Genetic diseases, on the other hand, are illnesses that are caused by mutations in the person’s DNA. One of the most common forms of research into the family link for alcoholism comes in the form of identical twin studies and study of the human genome, or genomic medicine. Identical twins share the same 23 chromosomes and can, therefore, provide insight into the heritability of diseases and traits. There are also countless environmental factors (work, stress, relationships) that may lead to alcoholism. In other words, psychology and home environment likely have a significant impact on how alcoholism is passed down through families. Although it can be hard to separate the different causes from each other, there is solid evidence that genes play a role.

Alcohol Abuse Is Influenced by Environmental and Genetic Factors

How do the roles of genetics impact the development of alcoholism throughout one’s life? What are some essential steps that can help prevent alcoholism later in life? These are all key questions to ask when approaching alcohol consumptions, and each question will be detailed and explained throughout this informative piece.

The expression ‘alcoholic parent, alcoholic child’ was common for generations, but we’re hoping to help dispel this notion in multiple ways. The inaccuracy of that statement is that it is absolute; it infers that, as a rule, a child of an alcoholic will always be an alcoholic – which could be damaging for those who have an alcoholic parent. No, you are not destined to become an alcoholic just because your parents were an alcoholic.

Peer groups – people, especially youth, who hang out in social groups that use alcohol or drugs are more likely to use themselves. This could be because they are already predisposed to substance use, but it may also be caused by a need to fit in and the utilization of substance as a social lubricant. A history of abuse – children who grew up in stressful environments, particularly those who were physically, verbally, or sexually abused are at a heightened risk of suffering from an AUD in adulthood. The goal of the research was to better understand how genes may contribute to alcohol problems as a way to develop improved and more personalized treatments.

  • Keep track of your daily basis, ask yourself – are my drinking habits safe or risky?
  • While you may have heard from word of mouth that a distant relative had an alcohol use disorder, that can mean various things.
  • The research on epigenetics and alcohol is still developing, but some studies suggest there is a link.
  • When it comes down to it, the environmental elements of growing up with an alcoholic parent are just as impactful, if not more, than genetic predisposition.
  • Jellinek was instrumental in establishing alcoholism as a disease with scientific considerations, per the Journal of Studies on Alcohol and Drugs.
  • It is still held that genetics accounts for about half of the risk of alcoholism.

Some can be personality-based, and the majority are surprisingly physical traits exhibited while drinking that discourage excess. Endorphins, or lack thereof, may also predispose someone to alcoholism, Medical News Today reports. Endorphins are what make you feel good when you do certain things or eat special foods. When alcohol wears off, the crash can include depressed moods while the brain struggles to reestablish a chemical balance without alcohol’s impact.

Because of a wide range of wild symptoms that blend into each other, recognizing a dual diagnosis can be difficult. The symptoms of each can also look vastly different from one person to the next. There is a distinct link between substance abuse problems and mental health issues such as anxiety, bipolar disorder,  and depression. Mixing alcohol with other drugs can also compound the risk of developing alcohol dependence. Drinking in moderation and limiting your alcohol consumption can help to decrease the odds of developing alcohol dependence and also for alcoholism. Research shows that genes are responsible for about half of the risk for AUD.
