The DRD2 gene was the first candidate gene that showed promise of an association with alcoholism. Alcoholism is a family disease which often results in a family member taking on the characteristics of the disease even if they are not true alcoholics. Dysfunctional relationships, denial, fearful, avoidance of feelings, poor coping skills, poor problem solving, afraid that others will find out what they are really like, etc. These adult children of alcoholics benefit from attending meetings of Adult Children of Alcoholics. Adult children of alcoholics appear to have certain characteristics in common as a result of being raised in an alcoholic home.
A growing body of scientific evidence seems to confirm alcoholism and a genetic predisposition. This means if you have more than one close relative with an alcohol use disorder, you may have inherited genes that put you at risk. That said, researchers in North and South America have come up with several treatment modalities for people with genes that influence alcoholism. For people with a family history of alcoholism, there are alcoholism treatments that create unpleasant effects as an alternative to behavioral therapy, medications, and detox. Still, therapy and medication are the preferred treatment modalities for alcoholism.
While alcoholism and genetics can explain why the condition runs in families, it’s important to realize this isn’t the only reason. It’s also not guaranteed, as about half of the risk is due to factors aside from genetics. 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.
Hereditary Alcoholism
Anybody can develop an SUD, and they can do it for any number of reasons in their life. The genetic connection to addiction comes through inherited levels of dopamine, a neurotransmitter made in your brain. Research shows that genetics have somewhere between a 40% and 60% influence on addiction. But does eco sober house complaints that mean your chance of addiction is essentially a coin flip if you have a family history of SUD? It’s a little more complicated than that, says addiction psychiatrist Akhil Anand, MD. If you are living with alcohol use disorder, know that you are not alone and that there are treatment options.
- “A family history of AUD increases the risk of a biological child suffering from AUD. The inheritance is about 50%, ranging from 40% to 60%.”
- Biological factors such as metabolism, how your brain and body process reward, and how alcohol affects you personally can all influence drinking patterns and potential issues with alcohol.
- Childhood abuse, parental struggles, and mental illness in close family members all contribute to the risk of developing an addiction to drugs or alcohol.
- Still, therapy and medication are the preferred treatment modalities for alcoholism.
- In the future, there may be genetic therapies that help people control how much alcohol they consume; for now, behavioral therapies have proven very effective at managing these chronic health conditions.
- In addition to affecting alcohol addiction risks, these genetic factors may lead to increased alcohol consumption and heighten the risk of alcohol-related diseases, including certain cancers.
Before this groundbreaking study, studies showed that alcohol abuse runs in families, but it could not point to the genetic basis of this finding. The study was possible because the Human Genome Project (2003) was able to identify every gene that exists in human DNA. 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 (chronic) condition characterized by a powerful, compulsive urge to drink alcohol and the inability to stop drinking after starting. In addition to alcoholism, alcohol use disorder includes alcohol abuse, which involves problem drinking without addiction.

I have come across very few people who have not been touched by this disease somewhere in their background, even though they were raised by non-drinking parents. 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.

psychological and social problems and contributes to many diseases.
The gene is the main physical unit that passes inheritance from a parent to their child. “Heredity” refers to a mutation in a person’s genes that is passed from generation to generation. Common hereditary mental illnesses include autism, attention-deficit hyperactivity disorder and depression. While there are differences between genetics and heredity, the terms are mostly interchangeable when talking about alcohol addiction.
Environmental Factors
I was far away from coveting the life of the airport alcoholic and convinced that a healthy relationship with alcohol was probably impossible. Experts hope that if they can trace alcoholism to one gene or a combination of genes, they could use the information to identify those at risk and create early prevention methods. 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.
- Contact a health care provider if you have questions about your health.
- This reinforces the desire to use alcohol as a coping mechanism for stress.
- Additionally, about 1.7% of adolescents ages 12 to 17 were reported as having alcohol use disorder in 2019.
Used by many addiction professionals to make a quick assessment of an individual. What makes me an alcoholic is what I do NOT where or what I come from. So the very ‘slipperiness’ of alcoholism has led to a multitude tests being devised.
Environmental Risk Factors for Alcohol Abuse
Jellinek was instrumental in establishing alcoholism as a disease with scientific considerations, per the Journal of Studies on Alcohol and Drugs. Alcohol consumption and drinking have played a role in society for centuries. “Genetic polymorphism in ethanol metaboli[…]abuse and alcoholism.” Molecular Psychiatry, May 26, 2004. “The heritability of alcohol use disorder[…]nd adoption studies.” Psychological Medicine, August 29, 2014.
To date, GWAS have
focused on common variants, with allele frequencies of 5% or higher. Most GWAS are case-control studies or studies of quantitative traits in
unrelated subjects, but family-based GWAS provide another approach. GWAS are
beginning to yield robust findings, although the experience in many diseases is
that very large numbers of subjects will be needed. To date, individual GWAS
studies on alcohol dependence https://sober-home.org/ and related phenotypes have been relatively modest
in size, and most do not reach genome-wide significance. This may reflect both
the limited sample sizes and the clinical and genetic heterogeneity of the
disease. 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.
Alcohol use disorder is a pattern of alcohol use that involves problems controlling your drinking, being preoccupied with alcohol or continuing to use alcohol even when it causes problems. This disorder also involves having to drink more to get the same effect or having withdrawal symptoms when you rapidly decrease or stop drinking. Alcohol use disorder includes a level of drinking that’s sometimes called alcoholism. Clearly, your family tree isn’t the sole indicator of addiction risk. The world around you also can play a significant role in opening a door that leads to problematic substance use, notes Dr. Anand. About half of your susceptibility to developing a substance use disorder (SUD) can be hereditary.
Living with an Alcoholic Family Member
When released, dopamine creates pleasure, and as well as being released naturally through rewarding activities such as eating or cuddling, dopamine is released by many illicit substances. Not everyone needs to cut back, but it’s never a bad idea to be mindful of your drinking habits. I couldn’t shake the fear that it was in my genes to lose control and burden everyone around me. No matter what the narrative might be, it doesn’t need to be a projection of you. The more my family members tried to convince me that there’s only one outcome for me, the harder my relationship with alcohol became. “Why would you do that when you know this family’s history,” he yelled in between sips of chard.
