Alcohol Dependence, Psychiatric Disorders Share Genetic Links

Chronic heavy drinking also increases the risk of kidney disease, diabetes, and several cancers. Genetics are 50 percent of the underlying reason for 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 to below 0.08 percent. In other words, individuals Transitional living are considered legally too drunk to drive if their BAC is 0.08 percent or higher. 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. In fact, new data suggests that there may be even more genetic variants involved in alcohol dependence. Our DNA dictates what we’ll look like and how we’ll behave.

Chances Of Developing Alcohol Abuse

A hereditary disease, on the other hand, means that a specific sequence of DNA abnormality was inherited from generations before. So when answering the question of whether alcoholism is genetic or hereditary, the answer is that it could be both. However, sometimes the pieces that are donated to your puzzle are a little bent or don’t fit quite right, meaning some traits are not preferable. For example, the gene for alcoholism can be passed down intergenerationally.

Using alcohol as a crutch, however, can be a slippery slope. Not only is it difficult to truly get to know someone while intoxicated, but it can also lead to dangerous behavior like drinking and driving or violence.

Alcohol is widely consumed, but excessive use creates serious physical, psychological and social problems and contributes to many diseases. Alcoholism 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 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.

Common Traits Of An Alcoholic

Among the behavioral traits parents can pass on to their children is a predisposition toward alcohol abuse and addiction. Other people carry genes that act in the brain rather than the liver and raise the risk of becoming an alcoholic. (Although if people with these genes never touch a drop, they would never become alcoholics.) Overall, those with an alcoholic parent or sibling are at three to four times the normal risk.

Individuals who know they and their relatives are at high risk for alcoholism may use this knowledge to protect themselves and their families. High risk individuals may be able to avoid drinking or can carefully monitor their intake of alcohol. It is very important to remember that not all relatives of alcoholics do develop problems with alcohol. This condition results from a combination of genetic, environmental, and lifestyle factors, some of which have not been identified.

Cessation Of Alcohol Intake

Women develop long-term complications of alcohol dependence more rapidly than do alcoholism genetic statistics men. Additionally, women have a higher mortality rate from alcoholism than men.

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. Co-occurring substance abuse and mental health issues are extremely common – roughly 50 percent of people with severe mental disorders are affected by substance abuse. Self-medication for mental health problems is common and can lead to addiction. Any use of alcohol is not recommended if an underlying mental health condition is present, and overuse of alcohol should be considered a huge warning flag for the development of progressive alcoholism. People with a family history of alcoholism have the highest risk of struggling with alcohol use.

Research Studies From Clinicaltrials Gov

The most common initial approach was linkage analysis, in which markers throughout the genome were measured to identify chromosomal regions that appeared to segregate with disease across many families. The drawback to this approach is that linkage studies find broad regions of the genome, often containing many hundreds of genes.

There is no one gene that determines a person’s risk of alcohol addiction. Rather, hundreds of genes can work to increase someone’s predisposition to alcoholism. How a person responds to these genes as well as countless environmental factors are what determines whether he or she develops an alcohol use disorder. 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.

If someone has a mutation in this area and does not produce enough GABA while sober, they are more likely to abuse alcohol to feel better. ADH1B — This gene causes someone to feel hot and sweaty, develop a face and body flush, and increase feelings of sickness when they consume alcohol. This gene affects the liver’s ability to metabolize alcohol. It helps stop people from drinking too much or too frequently. Learned behaviors also affect how a person views alcohol later in life. Even without a genetic component, a person can still develop AUD when raised in a certain environment.

Underage Drinking

In specific, studies that compare fraternal twins and identical twins can be particularly insightful. Among identical twins, their 23 chromosome pairs are exactly the same (i.e., identical twin are monozygotic). Fraternal twins do not have identical chromosome pairs; hence, they look different from each other. If addiction has a genetic basis, it would be expected that identical twins who carried the genes involved in addiction would similarly express them .

For studies of rare variants, families are quite valuable for sorting out true positives from the background of individual variations that we all harbor. Genetic makeup only accounts for half of the alcoholic equation. There are also countless environmental factors that may lead to alcoholism. Sharing developmentally appropriate information and education about the dangers of alcohol use and your family history.

Excessive alcohol use causes damage to brain function, and psychological health can be increasingly affected over time. Social skills are significantly impaired in people suffering from alcoholism due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. Psychiatric disorders are common in people with alcohol use disorders, with as many as 25 percent suffering severe psychiatric disturbances. The most prevalent psychiatric symptoms are anxiety and depression disorders. Psychiatric symptoms usually initially worsen during alcohol withdrawal, but typically improve or disappear with continued abstinence. Psychosis, confusion, and organic brain syndrome may be caused by alcohol misuse, which can lead to a misdiagnosis such as schizophrenia.

Understanding Addiction Transference

But, scientists are still attempting to answer the question, “Is alcoholism hereditary? Alcohol treatment professionals work with you to create a personalized comprehensive recovery plan with measurable goals. Comprehensive recovery plans may include inpatient or outpatient treatment, medication-assisted therapy, counseling and support groups. Relapsing does not mean you’ve failed and cannot overcome alcoholism. It makes you aware of triggers and may motivate you to seek additional help from a counselor or support group.

• By partnering with the Compliancy Group, we are demonstrating both our commitment to high-quality behavioral healthcare, as well as the importance we place on our patients’ privacy and personal health information.
• Interaction between the functional polymorphisms of the alcohol-metabolism genes in protection against alcoholism.
• This is especially true for those who begin drinking before the age of 15.
• And acamprosate , used in Europe but not available in the U.S., helps reduce alcohol craving.

People with unusual serotonin levels may be more likely to exhibit alcoholic behavior. Evaluating predisposition towards alcoholism using electrophysiological indices of information processing in high-risk individuals. In our laboratory we place a great deal of emphasis on the dynamic properties of oscillations in the human brain to increase our knowledge of information processing. These electroencephalographic oscillations have a superb time resolution, and are especially effective for studying the temporal interactions of brain processes involved in neural networks.

Before you know it, you’re heading to every company happy hour, drinking more frequently and even craving alcohol after a long workday – all warning signs of AUD. If you or a loved one is struggling with an alcohol use disorder, help is only a phone call away. Contact a treatment provider now to learn about available treatment options. Alcohol dependence can form quickly and aggressively, or it may surface over a longer period of time. Regardless of when or how a drinking problem starts, there are plenty of treatment options available to help get your life back on track.

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 was able to identify every gene that exists in human DNA. There is a distinct link between substance abuse problems and mental health issues such as anxiety, bipolar disorder, and depression. A dual diagnosis (or a diagnosis of two or more co-occurring disorders) is a precipitous, dangerous situation where alcohol use and the mental health issues are prone to exacerbating one another.
