Our hereditary behaviors interact with our environment to form the basis of our decisions. Some people are more sensitive to stress, making it harder to cope with an unhealthy relationship or a fast-paced job. Some people experience a traumatizing event and turn to alcohol to self-medicate. 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.
This is of particular concern when you’re taking certain medications that also depress the brain’s function. Alcohol use disorder can include periods of being drunk (alcohol intoxication) and symptoms of withdrawal. Having a close family relative, such as a parent, can account for up to 60% of your risk of developing AUD. That doesn’t mean you’ll absolutely develop AUD if you have a family member living with the condition.
Behavioral Treatments
Many studies related to the children of alcoholic parents show there are genetic factors that influence alcoholism. In fact, some studies found that approximately 45% to 65% of risks related to alcoholism may be caused by genetic factors. These studies show that children with a family history of alcohol addiction are twice as likely as the general population to suffer from alcohol-related issues. Moving forward, https://ecosoberhouse.com/ continued efforts to integrate large GWAS datasets examining alcohol use remain critical to the detection and replication of genome-wide significant associations. These findings will further our understanding of the genetic etiology of AUD, and will also promote the advancement of “Post-GWAS” approaches seeking to better understand the mechanisms through which genetic variation leads to increased AUD risk.
There are also behavioral genes passed down that could influence a propensity for alcoholism. Mental illnesses, such as depression and schizophrenia, are more https://ecosoberhouse.com/article/genetics-of-alcoholism-is-alcohol-abuse-hereditary/ common in people with a family history of these disorders. People with mental illness have a higher risk of turning to substance abuse as a way of coping.
CURRENT STATE OF THE AUD GWAS LITERATURE
In retrospect, those studies (despite sample sizes in the range of 1000–2000) were largely underpowered to detect risk variants of small effect. Current power and sample size estimates for GWAS with effect sizes of 1.05–1.2 range from 30,000 – 120,000 (Owen et al., 2010; Schizophrenia Working Group of the Psychiatric Genomics, 2014). While the use of a stringent P-value for GWAS avoids the detection of false positive findings, it might also miss ‘true’ variants. Recent attempts to address this issue have used pathway analysis and polygenic risk score approaches (Gelernter et al., 2014) but have not been widely applied to AUD genetic analyses. Alcohol Use Disorder (AUD) is a chronic psychiatric condition characterized by drinking patterns that lead to detrimental emotional, physical, and social outcomes. The Centers for Disease Control and Prevention (CDC) has reported that alcohol use contributes to approximately 88,000 deaths annually in the United States (Stahre et al., 2014), reflecting high morbidity and mortality.
Behavioral treatments—also known as alcohol counseling, or talk therapy, and provided by licensed therapists—are aimed at changing drinking behavior. Examples of behavioral treatments are brief interventions and reinforcement approaches, treatments that build motivation and teach skills for coping and preventing a return to drinking, and mindfulness-based therapies. One size does not fit all and a treatment approach that may work for one person may not work for another. Treatment can be outpatient and/or inpatient and be provided by specialty programs, therapists, and health care providers. While genetics can account for up to 60% of AUD risk, not everyone with a family history of AUD will develop the condition. Genetics aren’t the only way your parents or caregivers can influence AUD risk.
Genetical Sensitivities to Alcohol
It is hoped that such information will ultimately lead to improved prevention and treatment efforts. Over the past few years numerous whole genome linkage studies have been performed in which the inheritance of phenotypes and genetic markers is followed in families [12,40]. A subsequent COGA scan found strong linkage of resting EEG beta power, an intermediate phenotype for alcoholism, to the same chromosome 4 region [43]. This finding led to the discovery of the association of GABRA2 with AUD, a robust, widely replicated finding that will be discussed below. The more risk factors a person has, the greater the chance of developing an alcohol use disorder or addiction.
