Alcohol Use Disorder (AUD), formerly known as alcoholism, has been a topic of long-standing debate within the medical community regarding its classification as a mental illness. This article delves into the intricate relationship between alcohol addiction and mental health, illuminating the reasons behind the growing recognition of AUD as a genuine mental health condition.

Alcohol Use Disorder Defined
The American Psychiatric Association (APA) classified AUD as a medical and mental health condition in 2013, emphasizing its clinical nature rather than a moral failing.
It’s characterized by cognitive, emotional, and behavioral symptoms that significantly impact an individual’s life. If you or someone you know experiences cravings, withdrawal symptoms, and continues to drink despite negative consequences, it could be a sign of AUD.
This chronic disease often co-occurs with other mental health disorders, such as major depressive disorder and anxiety, which can complicate treatment efforts. The DSM-5-TR, the standard classification of mental disorders, categorizes AUD under substance use disorders.
This change in terminology from earlier terms like “alcohol abuse” and “alcohol dependence” aims to reduce stigma and promote clinical accuracy. Understanding AUD as a mental health condition emphasizes the need for compassionate care and effective treatment approaches rather than moral judgment.
Approximately 14% of U.S. adults are affected by AUD, highlighting its widespread impact on public health.

Characteristics of Alcoholism as a Mental Illness
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), recognizes alcohol use disorder (AUD) as a primary chronic disease, requiring at least two affirmative responses to 11 specified behavioral questions for a formal diagnosis. Symptoms of AUD include cravings for alcohol, increased tolerance, withdrawal symptoms, and continued use despite negative consequences, highlighting its nature as a mental health disorder.
Co-occurring mental health disorders, such as depression and anxiety, are prevalent among individuals with AUD, complicating treatment and recovery due to the interconnected nature of these conditions.
The American Medical Association has recognized alcoholism as a disease since 1956, emphasizing its chronic nature and the lack of voluntary control over alcohol use, paralleling other mental health disorders.

Neurobiological Basis
When you consume alcohol regularly, it alters your brain’s neurochemistry, affecting neurotransmitters like dopamine and GABA. These changes can lead to mood, cognitive, and behavioral issues that significantly impact your life.
If you have lower baseline dopamine levels, you’re more susceptible to addiction, as alcohol artificially elevates dopamine, reinforcing the desire to repeat use.
Over time, prolonged alcohol consumption results in neuroadaptations, increasing tolerance and withdrawal symptoms, further complicating the neurobiological landscape of addiction.
These neurobiological changes can also predispose you to additional mental health disorders, such as anxiety and depression, highlighting the interconnectedness of addiction and mental health.
Co-Occurring Mental Health Disorders
In 2018, a staggering 9.2 million U.S. adults experienced both AUD and a mental health condition, underscoring the significant overlap between these issues.
Depression, anxiety, and PTSD are among the most common mental health disorders that co-occur with AUD. Individuals struggling with depression may attempt to self-medicate with alcohol, creating a vicious cycle that exacerbates both the addiction and the underlying mental health issues.
The interaction between alcohol use and mental health conditions can lead to impaired cognitive function, severe mood swings, and an increased risk of developing additional mental health problems.
Impact on Mental Health
Alcohol’s devastating impact on mental health is a crucial factor in classifying Alcohol Use Disorder (AUD) as a mental illness. As a depressant, alcohol can worsen existing mental health issues and lead to cognitive impairments, mood swings, and emotional instability.
You might find yourself trapped in a vicious cycle of self-medication, where temporary relief from emotional distress leads to increased dependence and deteriorating mental well-being. Chronic alcohol consumption alters brain chemistry, resulting in neural pathway adaptations that contribute to long-lasting changes in mood and behavior.
To improve overall mental health outcomes, it’s crucial to address both addiction and mental health issues concurrently through comprehensive alcohol use disorder mental health treatment.
