Understanding Alcohol Use Disorder: Is It a Disease, a Mental Health Condition or Genetic? 

Alcohol consumption is a standard part of social life for many, but for some, it can spiral into a more serious issue—alcohol use disorder (AUD). With the rising awareness of its impact on mental health and overall well-being, many people are asking, what is alcohol use disorder, and how is it classified? Is it a disease? Is it a mental health condition? Does genetics influence it? In this blog, we’ll explore these questions and shed light on the complexities of alcohol use disorder.

What Is Alcohol Use Disorder?

Alcohol use disorder (AUD) is a medical condition characterized by the inability to control alcohol consumption despite adverse consequences. It can range from mild to severe and is diagnosed based on a variety of symptoms, including:

• A strong urge or craving to drink
• Drinking more or for a more extended period than intended
• Difficulty reducing or controlling alcohol use
• Spending a significant amount of time drinking or recovering from its effects
• Continued drinking despite its harmful effects on relationships, work or health

In addition, people with AUD may experience withdrawal symptoms such as anxiety, shaking, nausea and sweating when they attempt to cut back or stop drinking. These symptoms make it incredibly challenging for individuals to break free from the cycle of alcohol dependence.

Is Alcohol Use Disorder a Disease?

Yes, alcohol use disorder is classified as a disease. The medical community, including organizations like the American Medical Association (AMA) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), recognizes AUD as a chronic disease. It shares key characteristics with other chronic illnesses, such as heart disease or diabetes, including:

• A clear biological basis: Chronic alcohol use leads to changes in brain structure and function, particularly in areas related to reward, decision-making and impulse control.
• Predictable progression: Without treatment, AUD tends to worsen over time, much like other chronic diseases.
• Requires ongoing management: Just as with conditions like hypertension, managing AUD often involves a combination of behavioral changes, counseling and sometimes medication to help control cravings and prevent relapse.

Classifying AUD as a disease helps reduce the stigma surrounding addiction. It reinforces the understanding that those who suffer from alcohol dependence aren’t simply making poor life choices; they’re dealing with a complex, multi-faceted medical condition that requires professional intervention.

Is Alcohol Use Disorder a Mental Illness?

Is alcohol use disorder a mental illness? Is another frequently asked question. AUD falls under the umbrella of mental health conditions. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), AUD is listed as a substance-related and addictive disorder, which categorizes it as a mental health disorder. This classification acknowledges the role that psychological factors play in the development and persistence of AUD.

Moreover, alcohol use disorder often co-occurs with other mental health conditions, such as depression, anxiety and post-traumatic stress disorder (PTSD). Individuals with mental health disorders are at a higher risk of developing AUD. This link is known as a dual diagnosis or co-occurring disorder, and it highlights the complex relationship between alcohol use and mental health. In many cases, individuals may use alcohol as a way to self-medicate for underlying mental health issues, leading to a vicious cycle of dependence and worsening psychological symptoms.

The recognition of AUD as both a disease and a mental health disorder helps underscore the importance of treating it from a holistic perspective. Effective treatment plans often incorporate therapy, such as cognitive-behavioral therapy (CBT), to address the psychological factors that contribute to the disorder, in addition to medical interventions aimed at reducing alcohol dependence.

The Role of Genetics in Alcohol Use Disorder

Research shows that genetics play a significant role in the development of alcohol use disorder. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), genetics are responsible for approximately 40-60% of an individual’s risk for developing AUD.

Specific genes influence how a person metabolizes alcohol, their sensitivity to its effects, and how much they enjoy the experience of drinking. For example, variations in genes that affect the enzymes responsible for breaking down alcohol can make some individuals more susceptible to developing AUD. Furthermore, individuals with a family history of

alcohol use disorder are at a significantly higher risk of developing it themselves. This hereditary risk is due to both genetic predisposition and environmental factors, such as exposure to drinking behaviors during childhood or adolescence.

However, it’s important to note that while genetics play a significant role, they do not determine a person’s fate. Not everyone with a family history of AUD will develop the disorder, and individuals without a family history can still create it due to other risk factors like trauma, stress or peer pressure. Therefore, while genetics contribute to the likelihood of developing alcohol use disorder, environmental and behavioral factors are equally important.

A Multifaceted Condition

So, what is alcohol use disorder? It’s a chronic disease, a mental health condition and one that is influenced by genetics. AUD is a complex disorder with physical, psychological and genetic components. Understanding it as a disease helps reduce stigma and frames it as a medical condition requiring professional intervention. Recognizing its classification as a mental health disorder underscores the importance of addressing the psychological aspects that often drive alcohol dependence. Lastly, appreciating the role of genetics helps illuminate why some individuals may be more vulnerable to developing the disorder than others.

Addressing AUD requires a multifaceted approach that includes medical treatment, psychological therapy and lifestyle changes. Whether you or someone you know is struggling with alcohol use disorder, understanding the full scope of the condition is the first step toward finding effective help and support.
