Among those with comorbid occurrences, a distinction is commonly made between depressive episodes that remit with alcohol abstinence (“substance-induced”), and depressive episodes that are primary and do not remit with abstinence (“independent” episodes). Psychosis, confusion, and organic brain syndrome may be caused by alcohol misuse, which can lead to a misdiagnosis such as schizophrenia. Psychiatric symptoms usually initially worsen during alcohol withdrawal, but typically improve or disappear with continued abstinence. Excessive alcohol use causes damage to brain function, and psychological health can be increasingly affected over time. Severe cognitive problems are common; approximately 10% of all dementia cases are related to alcohol consumption, making it the second leading cause of dementia. The amount of alcohol that can be biologically processed and its effects differ between sexes.
Behavioral and Addiction Genetics
The heterogeneity of AUD, coupled with varying degrees of alcohol exposure in different groups and stages of the disorder, introduce complexities in interpreting findings, especially in small samples. As technology advances and research methodologies are refined, the field of epigenetics is expected to profoundly contribute to unraveling the complexities of AUD. The integration of DNA methylation, histone modifications, and noncoding RNAs into our understanding of AUD pathogenesis holds promise for identifying novel therapeutic targets and developing personalized interventions.
Potential Therapies Targeting Genetic Influences on Alcoholism
- Since then numerous studies, nearly all in Caucasians, have replicated this association although there have also been negative findings .
- Panic disorder can develop or worsen as a direct result of long-term alcohol misuse.
- Genetic testing for alcoholism should only be conducted with the voluntary and informed consent of the individual.
- This pattern, in turn, leads family, physicians, and others to be more likely to suspect that a man they know is someone with an alcohol use disorder.
- Personalized treatment approaches that take into account an individual’s genetic profile may lead to more successful outcomes.
The interaction between genes and environmental factors is complex, and genetic testing alone cannot account for all the variables involved. However, it is important to note that genetics is only one contributing factor and cannot solely explain the prevalence of alcoholism in specific ethnicities. Environmental factors, such as upbringing, peer influence, and access to alcohol also play a role in the development of alcohol addiction. Advances in technology and the availability of large-scale genetic databases have opened up new avenues for research on alcohol addiction.
This suggests that there may be genetic factors that are passed down from generation to generation, increasing the likelihood of alcohol addiction. In fact, the risk of alcohol addiction can be up to four times higher in individuals with close relatives who are alcoholics, compared to those without a family history of the disease. Studies have shown that individuals who have a family history of alcoholism have a higher likelihood of developing the disorder themselves. Besides the well-known functional coding variants in the alcohol metabolic genes, most variants identified through large GWAS have small to very small effects on the risk of AUD, reducing the yield of the extensive effort of following functional studies on individual variants.
Prevention
Much of the treatment community for alcoholism supports an abstinence-based zero tolerance approach popularized by the 12 step program of Alcoholics Anonymous; however, some prefer a harm-reduction approach. Those who approach alcoholism as a medical condition or disease recommend differing treatments from, for instance, those who approach the condition as one of social choice. Because alcohol is often used for self-medication of conditions like anxiety temporarily, prevention of alcoholism may be attempted by reducing the severity or prevalence of stress and anxiety in individuals. This pattern, in turn, leads family, physicians, and others to be more likely to suspect that a man they know is someone with an alcohol use disorder. This pattern, in turn, leads family, physicians, and others to be less likely to suspect that a woman they know has alcohol use disorder.
Studies also suggest that it may play a part in the development of cancers of the liver, breast, respiratory tract, and digestive tract as well as in fetal alcohol syndrome. Gamma-aminobutyric acid (GABA) are the most important inhibitory receptors and are involved in the rewarding circuit; alcohol acts as an agonist or of the GABAA receptor. Alcoholism is a relatively common chronic and relapsing disorder that results in significant health and social consequences. Early exposure to alcohol can have detrimental effects on fetal and child development, potentially leading to lifelong challenges. There is no obligation to enter treatment.
- The strongest and most consistent findings for GWAS for AUD are for alcohol metabolizing genes, as in a recent study in an East Asian (Korean) sample of alcoholics in which ALDH2 and ADH1B showed up as GWAS signals with genome-wide significance .
- Here’s how one can assess the likelihood of developing AUD.
- The term alcoholism was first coined in 1852, but alcoholism and alcoholic are considered stigmatizing and likely to discourage seeking treatment, so diagnostic terms such as alcohol use disorder and alcohol dependence are often used instead in a clinical context.
- They may develop shame over their inadequacy to liberate their parents from alcoholism and, as a result of this, may develop self-image problems, which can lead to depression.
- Equal dosages of alcohol consumed by men and women generally result in women having higher blood alcohol concentrations (BACs), since women generally have a lower weight and higher percentage of body fat and therefore a lower volume of distribution for alcohol than men.
Environmental factors, such as peer influence, availability of alcohol, and stressful life events, also play a significant role in the development of alcohol addiction. However, it is important to note that genetics alone do not determine whether a person will develop alcoholism. This suggests that there is an inherited component to alcoholism, where certain genes that predispose individuals to addictive behaviors are passed down through generations.

This study examined overlapped genes by both gene-based association analysis and TWAS (82) in brain tissues and/or chromatin interaction analysis (83) using Hi-C brain annotations. Phenome-wide PRS analysis in the independent biobank BioVU confirmed the genetic correlations between PAU and substance use and psychiatric disorders. Specifically, this study identified a set of variants with effects on AUD that are not mediated through alcohol consumption (i.e., AUDIT-C) (77). Prior to these two key papers, it was not recognized that quantity/frequency versus dependence measures differed genetically and therefore biologically. Another key finding from this study is that the genetic architecture of AUDIT-P differed from AUDIT-C, and AUDIT-P is genetically correlated with AUD more strongly than AUDIT-C.

This is believed to be due to alcohol causing physiological distortion of brain chemistry, as well as social isolation. There is a high rate of suicide in chronic alcoholics, which increases the longer a person drinks. The most common cause of death in alcoholics is from cardiovascular complications. In the United States, 30% of people admitted to hospital have a problem related to alcohol. Estonia had the highest death rate from alcohol in Europe in 2015 at 8.8 per 100,000 population. Dependence on other sedative-hypnotics such as zolpidem and zopiclone as well as opiates and illegal drugs is common in alcoholics.
Alcohol Withdrawal
A 2008 review of the effectiveness of topiramate concluded that the results of published trials are promising, however as of 2008, data was insufficient to support using topiramate in conjunction with brief weekly compliance counseling as a first-line agent for alcohol dependence. The study found abstinence from alcohol was the most stable form of remission for recovering alcoholics. A follow-up study, using the same subjects that were judged to be in remission in 2001–2002, examined the rates of return to problem drinking in 2004–2005. Propofol also might enhance treatment for individuals showing limited therapeutic response to a benzodiazepine.
Therefore, therapies that target the interaction between genes and the environment may be particularly effective in preventing or treating alcoholism. Stressful life events and trauma can also play a significant role in the development of alcohol addiction. Family history of alcoholism can increase an individual’s risk, as they may be more likely to be exposed to alcohol and develop unhealthy behaviors from a young age. Environmental factors such as family relationships, social interactions, and exposure to alcohol can all contribute to the development of alcoholism.
Genetic counseling plays a key role in providing education and support for individuals who may have inherited a predisposition to alcoholism. Overall, while genetic testing for alcoholism offers valuable insights, it must be employed responsibly and with consideration for the ethical implications. However, there are several ethical considerations that need to be taken into account when conducting genetic testing for alcoholism.
Alcohol metabolism and the risk for AUD
We do not receive any fee or commission dependent upon which treatment or provider a caller chooses. Calls to numbers marked with (I) symbols will be answered or returned by one of the treatment providers listed in our Terms and Conditions, each of which is a paid advertiser. These programs usually last between one and three months and offer everything from group therapy and individual counseling to holistic treatments like exercise and meditation. Withdrawal can be severe, sometimes leading to seizures, hallucinations, or delirium tremens (DTs) in cases of heavy dependence. The first step when seeking help for problematic alcohol use is detoxification to help manage withdrawal symptoms.
The genetic component of AUD is well-established. Several genes have been implicated in the development of AUD. Genetic research, including twin and family studies, has demonstrated family AUD clusters. Alcohol use disorder (AUD) is a chronic condition with serious effects on individuals and society. The causes of AUD are complex and can involve a variety of factors, including early exposure to alcohol use, peer group pressure, and living with other mental health conditions. This risk is considered hereditary and may be passed down to you if you have a family history of AUD.
On the other hand, certain variations of the gene produce enzymes that metabolize alcohol more slowly, leading to a higher risk of alcohol addiction. Further research is needed to fully understand the genetic underpinnings of alcoholism and develop more effective prevention and treatment strategies. Additionally, genetic research can contribute to the development of medications and therapies that target the underlying genetic mechanisms of alcohol addiction. By identifying individuals who are genetically predisposed to addiction, healthcare professionals can tailor treatment plans that address their specific needs.
By analyzing an individual’s genetic makeup, it can be determined if there is a genetic predisposition towards alcohol addiction. By analyzing an individual’s unique genetic makeup, researchers can identify specific genetic markers that may increase the likelihood of developing an addiction to alcohol. By identifying the specific genes and genetic pathways involved, researchers are now able to develop targeted therapies that address the underlying genetic influences on alcohol addiction. By developing therapies that target these specific genetic factors, it may be possible to modify behavior and reduce the risk of addiction.
Alcoholism and addiction are complex disorders influenced by a combination of genetic and environmental factors. By understanding their genetic risk factors, individuals can make informed decisions about their alcohol consumption and take proactive steps to reduce their risk. By doing so, we can harness the power of genetics to better understand and address the complex nature of alcohol addiction. It can help identify individuals who are at a higher risk Genetics and alcoholism for developing alcohol addiction, allowing for targeted prevention and intervention strategies.
