Genetics and alcoholism PMC

However, scientists have not yet identified any single gene or gene cluster that guarantees that someone will develop alcohol use disorder (which is the clinical term for alcoholism). Scientists are researching how genes may influence the effectiveness of treatments for AUD. The drug Naltrexone shows to help reduce drinking for some, but not all, patients with AUD. Research shows that patients that have a variation in a specific gene respond positively to the drug while those without the specific gene do not. A better understanding of how genes affect treatment outcomes will help doctors prescribe the treatment that will help each patient.

• But your odds of developing a dependency may be higher because of this relation.
• In other words, individuals are considered legally too drunk to drive if their BAC is 0.08 percent or higher.
• Ultimately, genetics can play a role in the likelihood of developing an addiction but it is not the only factor at play.

A qualified team can dig deep into your reasons for drinking, and together, you can find solutions that allow you to stop drinking and rebuild your life in a healthy way. Some people carry a gene that makes them feel queasy and flushed when they drink. That gene makes alcohol unpleasant, making them less likely to drink too much.

People with enzyme variants that allow for the fast buildup of acetaldehyde from alcohol (ethanol) are at less risk for addiction compared to those who metabolize alcohol efficiently to acetate. This is because people with acetaldehyde buildup are more likely to have troublesome reactions. They would experience nausea, flushing, and rapid heartbeat even with moderate amounts of liquor. The unpleasant symptoms of drinking “protects” them from consuming too much alcohol. Among the behavioral traits parents can pass on to their children is a predisposition toward alcohol abuse and addiction.

• Meta-analyses, which
  combine results across a number of studies in order to attain the critical
  sample sizes needed, are being developed.
• When looking at the condition from this vantage point, it’s fair to say there’s a hereditary aspect.
• However, alcohol can turn into an unhealthy coping mechanism for stress or poor mental health, one that can lead to the development of risky conditions such as addiction.
• A dual diagnosis (or a diagnosis of two or more co-occurring disorders) is a precipitous, dangerous situation where alcohol use and mental health issues are prone to exacerbate one another.
• In order to treat each individual case of addiction, the person needs to be treated on individual terms.

Underlying mental health issues, including schizophrenia, depression, and personality disorders are closely tied to alcoholism. Addressing these mental health issues properly could mean avoiding an alcoholism problem. Factors like environment and your ability to handle stress and situations that may trigger dependency are also important. It is likely that, as with most complex diseases, alcohol dependence is due to variations in hundreds of genes, interacting with different social environments. Genes that affect alcohol consumption may increase the overall risk by increasing drinking, or reduce risk by reducing drinking. However, for those who have the genes that reduce drinking and drink heavily despite them, the risk increases.

That pause could be just what you need to resist the temptation. If you’re able to process your past, you’ll be less likely to turn to substances to cope. The information that is collected during your assessment can help your treatment team determine which levels of care and types of treatment are best for you. This is an emergency situation, and 911 should be called immediately if someone is showing symptoms of alcohol poisoning. Why does AUD seem to be so common in some people and not others?

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. Thus, the
genes and SNPs found through GWAS have had little overlap with previous findings
based on candidate genes/pathways and linkage analyses.

Symptoms of Alcoholism

Families, where the annual household income is more than $75,000, have a greater likelihood of having a family member suffer from alcohol use disorder. Alcohol is not inexpensive and if someone can’t afford to drink, they simply won’t be able to do so. This means that family wealth also contributes to the development of alcoholism. There is no alcoholic gene that people inherit that ultimately determines they will engage in alcohol abuse but rather a variety of genes that can ultimately lead to its development.

They further concluded that different genetic factors predispose people to alcoholism. Concerns about alcohol consumption should be addressed by a medical professional. Feeling out of control in regard to drinking and feeling as though one drinks too much are indicators that there is a problem. Medically supervised sober house detox programs and evidence-based rehabilitation programs are available that specialize in treating AUD. 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.

Iris Healing® is founded on a patient-first program that addresses your unique needs from a spiritual approach to help restore balance and aid in recovery from alcoholism. We are proud to continually equip you or your loved one with the necessary tools to regain autonomy over your own life, wellness, and long lasting sobriety. 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. 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. Even more prevalent than these factors is engaging in enabling and sympathetic drinking with a significant other who is abusing alcohol.
