Alcohol abuse is a phrase used to refer to the improper use of alcohol, which may cause physical, social, or moral harm to the drinker. It is often used interchangeably with the terms alcohol dependence, alcohol addiction, and alcoholism. However, the term alcoholism is not a recognized diagnosis due to its ambiguous definition and stigmatized connotations, and terms such as alcohol abuse or alcohol use disorder (AUD) are preferred in professional and research contexts. AUD is a medical condition characterized by an impaired ability to stop or control alcohol consumption despite adverse consequences, and it can range from mild to severe. Treatment options for AUD include medication, behavioral therapy, and mutual-support groups, and recovery is possible regardless of severity.

What You'll Learn

Alcohol use disorder (AUD)
Alcohol abuse is a term that is often used to refer to the misuse of alcohol, which may cause physical, social, or moral harm to the drinker. Alcohol use disorder (AUD) is the medical term for this condition. AUD is defined as a chronic, relapsing brain disorder characterised by an impaired ability to stop or control alcohol consumption despite adverse social, occupational, or health consequences. AUD can be mild, moderate, or severe, and is influenced by genetic and environmental factors. It is often perpetuated by lasting changes in the brain caused by alcohol misuse, which makes individuals vulnerable to relapse.
The risk factors for developing AUD include the amount, frequency, and speed of alcohol consumption, as well as age and gender. Research has shown that individuals who began drinking at an early age, especially females, are more likely to develop AUD. Genetics also play a significant role, with hereditability accounting for approximately 60% of the risk. Mental health conditions, such as depression, post-traumatic stress disorder, and attention deficit hyperactivity disorder, are also associated with an increased risk of AUD.
AUD treatment options include behavioural therapies, mutual-support groups, and medications such as naltrexone, acamprosate, and disulfiram. These treatments can be provided on an outpatient or inpatient basis by specialty programs, therapists, and healthcare providers. It is important to note that individuals with severe AUD may require medical assistance to manage alcohol withdrawal symptoms if they decide to stop drinking.
The term "alcoholism" is not a recognised diagnosis due to its ambiguous definition and stigmatised connotations. Instead, the preferred terms in professional and research contexts are alcohol abuse, alcohol dependence, or alcohol use disorder (AUD).

Binge drinking
The Substance Abuse and Mental Health Services Administration (SAMHSA) defines binge drinking as consuming five or more alcoholic beverages for males or four or more for females on the same occasion, at least once in the past 30 days. This definition focuses on the frequency and quantity of consumption rather than the BAC level. Other organisations, such as the Monitoring the Future (MTF) survey, define binge drinking as consuming five or more drinks in a row within a two-week period.
High-intensity drinking is a form of binge drinking that involves consuming two or more times the sex-specific thresholds. This means 10 or more standard drinks for males and eight or more for females. It is associated with more severe health risks and consequences. Binge drinking is considered a form of alcohol misuse, which can increase the risk of developing an alcohol use disorder (AUD). AUD is characterised by an impaired ability to control alcohol consumption despite adverse social, occupational, or health consequences. It encompasses conditions previously referred to as alcohol abuse, alcohol dependence, alcohol addiction, and alcoholism.

Alcohol withdrawal
Alcohol abuse, alcohol dependence, and alcohol use disorder (AUD) are terms used to describe the harmful use of alcohol. AUD is a medical condition characterised by a person's impaired ability to stop or control their alcohol consumption despite adverse social, occupational, or health consequences. It is considered a chronic brain disorder that can range from mild to severe.
Withdrawal symptoms can begin within six to twelve hours of the last drink and tend to peak within 24 to 72 hours. Mild symptoms include headache, anxiety, insomnia, upset stomach, and nervousness. More severe symptoms include hallucinations, increased blood pressure, rapid heart rate, high body temperature, tremors, and seizures. The most severe form of alcohol withdrawal is delirium tremens, which can be fatal.
Treatment for alcohol withdrawal depends on the severity of symptoms. Mild to moderate symptoms can often be managed in an outpatient setting, while more severe cases may require hospitalisation. Medications are prescribed to address symptoms and make the withdrawal process safer and less distressing. It is important for individuals experiencing alcohol withdrawal to have supportive surroundings to avoid unhealthy alcohol use, and lifelong abstinence from alcohol is recommended following withdrawal.
While alcohol withdrawal can be challenging, most people who go through it make a full recovery. Treatment options such as behavioural therapies, mutual-support groups, and medications can help individuals with AUD achieve and maintain recovery.

Alcohol-related brain changes
Alcohol abuse, alcohol dependence, heavy drinking, problem drinking, and alcohol use disorder (AUD) are terms used to describe the excessive consumption of alcohol. Alcohol use disorder is a chronic, relapsing brain disorder characterised by an impaired ability to stop or control alcohol consumption despite adverse social, occupational, or health consequences.
Alcohol-related brain damage (ARBD) is caused by regular drinking or binge drinking much more alcohol than the recommended limit over several years. Binge drinking is defined as consuming five or more beverages containing alcohol for males or four or more drinks for females on the same occasion. Binge drinking can also be defined as consuming two or more times the sex-specific thresholds, which is 10 or more drinks for males and eight or more for females. Binge drinking is a form of alcohol misuse, which refers to drinking in a manner, situation, amount, or frequency that could cause harm to oneself or others. Alcohol misuse also includes heavy drinking, which is defined as drinking five or more drinks for males or four or more drinks for females on each of five or more days in a month.
Alcohol abuse can cause deficits in the brain over time. Alcohol affects the whole body but takes a particular toll on the brain. It interferes with the brain's communication pathways and can affect how the brain processes information. It can also affect the way the brain looks and works. Alcohol makes it harder for the brain areas controlling balance, memory, speech, and judgment to do their jobs, resulting in a higher likelihood of injuries and other negative outcomes. Long-term heavy drinking causes alterations in the neurons, such as reductions in their size. Adolescent brains are more vulnerable to the negative effects of alcohol than adult brains. Misuse of alcohol during adolescence can alter brain development, potentially resulting in long-lasting changes in brain structure and function.
The brain's ability to return to normal following long-term sobriety is not fully understood, but studies indicate that some AUD-induced brain changes can improve and possibly reverse with months of abstinence from drinking. However, alcohol overdose can lead to permanent brain damage or death. An alcohol overdose occurs when there is so much alcohol in the bloodstream that areas of the brain controlling basic life-support functions, such as breathing, heart rate, and temperature control, begin to shut down.

Treatment and recovery
Alcohol abuse is a term that is often used interchangeably with alcohol dependence, alcohol addiction, and alcoholism. However, the term "alcoholism" is not a recognized diagnosis due to its ambiguous definition and stigmatized connotations. Instead, alcohol abuse is now referred to as Alcohol Use Disorder (AUD) in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and alcohol dependence in the International Classification of Diseases (ICD-11). AUD is characterized by an impaired ability to stop or control alcohol consumption despite the negative impact on one's social life, occupation, or health. It is considered a chronic relapsing brain disorder that can range from mild to severe.
Treatment for AUD aims to help individuals reduce their alcohol consumption and improve their overall well-being. The first step towards recovery is recognizing that there is an issue and seeking help from a healthcare provider. Treatment options may include:
- Mutual-support groups: These groups provide peer support for stopping or reducing drinking. They are typically available at low or no cost and can be easily accessed in most communities or online. Combining participation in these groups with medical treatment can offer valuable additional support.
- Behavioral therapies: These therapies help individuals develop skills to avoid and cope with triggers that may lead to drinking, such as stress.
- Medication: Medications such as naltrexone, acamprosate, topiramate, gabapentin, and disulfiram can be prescribed by a doctor to help reduce cravings and manage withdrawal symptoms.
- E-health tools: Digital tools and resources have also been shown to be effective in helping individuals overcome alcohol problems.
It is important to note that recovery from AUD is an ongoing process and setbacks are common. Treatment plans should be adjusted over time to aid long-term recovery. Additionally, addressing any accompanying medical and mental health issues is crucial for a comprehensive recovery.
National helplines, such as the Substance Abuse and Mental Health Services Administration's (SAMHSA) National Helpline, offer free and confidential treatment referral and information services for individuals and families facing alcohol abuse issues. These services can provide referrals to local treatment facilities, support groups, and community-based organizations.

Frequently asked questions
Alcohol abuse is a form of alcohol misuse, which refers to drinking in a manner, situation, amount, or frequency that may cause harm to oneself or others. Alcohol abuse is a component of alcohol use disorder (AUD), a chronic relapsing brain disorder characterized by an impaired ability to stop or control alcohol use despite adverse consequences.
Signs of alcohol abuse are related to alcohol's effects on organ systems. Alcohol abuse can lead to acute central nervous system depression, resulting in inebriation, euphoria, impulsivity, sedation, and poor judgment. Chronic alcohol abuse may cause dependence, reckless behavior, anxiety, irritability, insomnia, and chronic fatigue. Additionally, it can have detrimental effects on the liver, increasing the risk of elevated liver enzyme levels, cirrhosis, and liver failure.
Treatment for alcohol abuse typically involves a combination of medication, behavioral therapy, and social support. Medications such as acamprosate, disulfiram, naltrexone pills, and injectable naltrexone can help reduce alcohol consumption. Behavioral therapies, including Motivational Enhancement Therapy (MET) and mindfulness-based interventions, aim to change drinking patterns and reduce alcohol intake. Social support, through mutual-support groups and outpatient programs, provides valuable assistance and encourages those struggling with alcohol abuse to seek treatment.
Alcohol abuse carries various risks, including social, occupational, and health consequences. It can lead to damaged personal relationships, legal problems, and adverse effects on physical and mental health. Additionally, alcohol abuse increases the risk of developing esophageal cancer and other complications such as alcohol-induced hepatitis, alcohol poisoning, cerebellar degeneration, and delirium tremens.
