He is the medical monitor for the Physician Counseling Committee of the Harris County Medical Society and the Medical Director of Serenity House Detox. Additionally, other mental health conditions like depression or anxiety can also cause someone to turn to alcohol to help self-soothe. In some instances, the person may not even realize the mental health condition is present. These underlying causes can also be genetic, and if there is a family member that never received treatment for their mental health condition, other family members may never realize they have a mental health disorder as well. ADS is caused by variations in several genes that influence the way alcohol is metabolized and is linked to an increased craving for alcohol, higher levels of tolerance as well as an increased risk of physical dependence.
- 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. - Mutations of the GABRB1 gene can increase the risk of AUD, while the ADH1B and ALDH2 genes protect against it.
- The researchers also found that the genetic factors related to simply drinking alcohol were a little different from the genetic factors that contributed to alcohol dependence.
- As whole exome and whole genome sequencing
technologies come down in cost, they are being applied to identifying rare
variants. - Studies are
revealing other genes in which variants impact risk for alcoholism or related
traits, including GABRA2, CHRM2,
KCNJ6, and AUTS2.
Having alcoholic family members doesn’t mean you’re going to abuse alcohol yourself. When you know you have a genetic predisposition, it’s important to understand the symptoms of addiction. If you find you are exhibiting signs of alcoholism, seek treatment as soon as possible. In these situations, your hereditary behaviors interact with your environment forming the basis of your decisions. If you are more prone to stress, this can make it harder to deal with unhealthy environmental risks, leading you to turn to alcohol to cope. Partly — heredity is only responsible for about half of one’s risk of alcoholism.
Alcohol Addiction And Genetics
Even more prevalent than these factors is engaging in enabling and sympathetic drinking with a significant other who is abusing alcohol. 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.
She said those larger samples of individuals with and without a diagnosis of alcohol dependence will be key to future discoveries about genetic contributions to alcoholism. 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. Additionally, not all mental health issues are the same; some mental health issues, such as schizophrenia, require vastly different considerations than anxiety, panic attacks, depression, and other co-occurring disorders.
Environmental Factors that Contribute to Alcoholism
The more family members (related by birth) you have with an alcohol problem, the higher your risk. However, even those with a high genetic risk to substance abuse must first be driven by a nonhereditary factor to do it. The catalyst that leads to alcohol abuse is very often an environmental factor, such as work-related stress.
At Family First Intervention, we have worked hard to educate families on alcoholism and recovery from alcohol addiction. We have decades of experience in helping families take the difficult yet necessary first steps toward alcohol recovery. 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.
Genetics Of Alcoholism
They can couple with genetic risk and result in permissive attitudes toward heavy drinking and intoxication, he says. Instead, hundreds of genes inside your DNA can potentially amplify your risk of developing an alcohol use disorder. So, no one knows just how big a factor genetics plays in the development of alcoholism.
- Your prefrontal cortex is less formed in youth, meaning you have less impulse control and ability to fully process potential consequences.
- Environmental influences are other components that can lead to alcohol addiction, either singularly or as they interact with other factors.
- If you have a genetic risk of developing an alcohol addiction and have exhibited signs of this disorder, it’s important to seek treatment as soon as possible.
- Alcoholism is a serious problem and one estimate suggests that as many as 18 million adults in the country struggle with alcohol use disorder; that is one in 12 individuals.
- They seem to lose fewer inhibitions and tolerate alcohol for longer before they pass out.
Studies show that alcoholism is approximately 50% attributable to genetics. According to Adinoff, the only way to prevent AUD is to never drink alcohol. However, minimizing environmental factors that increase the risk, decreasing the availability of alcohol, and maximizing protective factors can help reduce the likelihood of developing AUD. If anyone is exposed to large amounts of an addictive substance over an extended period, is alcoholism inherited it is likely that their brain will rewire to crave the substance. Even without a genetic component present, a person can still inherit a predisposition to alcohol use disorder due to the culture they grow up in. Although alcohol consumption does not affect all people equally, according to scientists, different endorphin levels make these individuals more sensitive to alcohol and, therefore, more susceptible to being dependent.
Growing Up Around Alcohol
Genetics and family history are the most correlated with risk of AUD; in fact, genetic risk is about half of the problem, while family history is the other half. Certainly, genetics are passed down through families, but family history also includes the environment in which one was raised. Childhood abuse, parental struggles, and mental illness in close family members all contribute to the risk of developing an addiction to drugs or alcohol. If you have a genetic risk of developing an alcohol addiction and have exhibited signs of this disorder, it’s important to seek treatment as soon as possible.
Children of alcoholic parents or grandparents often struggle with problem drinking themselves. More recent studies digging deep into the science behind this disease are trying to discover if there is a genetic predisposition for alcoholism. A person with a genetic disease has an abnormality in their genome; an individual with a hereditary disease has received a genetic mutation from their parents’ DNA. When scientists debate whether alcohol use disorder is genetic or hereditary, they debate whether the condition stems from a larger set of genes that are passed down or if the disease stems from mutations in some genes. Even if someone is born with genes that predispose them to alcoholism this only accounts for half of the overall risk.
