The Role of Genetics in Alcohol Addiction

Does Alcoholism Run in the Family?

According to the National Institute on Alcohol Abuse and Alcoholism genes may account for 50% of the risk for someone to develop Alcohol Use Disorder.   These genes may explain why alcoholism seems to “run in the family.”  Certain genes affect things like behavior control, a known risk factor for addiction.  In addition, genes can affect our response to stress or our ability to react to situations.  All of these can influence how we respond to alcohol and drugs and the relationship we develop with these substances.

While it is clear that genetics can play a defining role in determining whether someone may develop alcohol use disorder, research has also shown that they are not the only culprit.  Other factors such as environment and exposure may also contribute to the likelihood that someone could develop an addiction.  Clearly some people are predisposed to addiction, but it is not a guarantee that they will become addicted.  Many people who are predisposed to alcoholism do not become dependent.  It is usually the combination between genetics and environment.

For anyone suffering from alcohol use disorder, the most important thing is seeking treatment.  Recovery from addiction is not a one-size-fits-all approach.  It is different for everyone.  Alcohol addiction or dependence can affect everyone in the family.  The more that you know about addiction and the treatment options available, the more likely you will be successful in recovery, avoiding triggers and preventing relapse.
