Alcohol Use Disorder (AUD) is a medical condition characterised by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD can be mild, moderate, or severe, with severity based on the number of symptoms a person exhibits. Excessive alcohol consumption can lead to alcohol-related brain damage (ARBD) or alcohol-related brain impairment (ARBI), causing memory loss, confusion, and problems with vision and communication skills. ARBD is a type of brain disorder that can lead to addiction and dependence on alcohol, making treatment challenging. Alcoholic organic brain disease, a severe form of ARBD, may result from nutritional deficiencies and ethanol neurotoxicity, causing brain lesions and cortical neuropathological changes. Treatment for AUD and its associated brain disorders includes behavioural therapy, medication, and mutual-support groups, with inpatient and outpatient options available.

What You'll Learn
Alcohol-related brain damage (ARBD)
ARBD is an umbrella term encompassing various conditions caused by long-term heavy drinking. The damage caused by ARBD can be stabilised or even partially or fully reversed with the right treatment and abstinence from alcohol. Brain scans have shown that some of the damage caused by excessive drinking can be reversed if the person stops drinking and receives the proper support. High doses of thiamine (vitamin B1) and a healthy diet with vitamin supplements can aid in the recovery process.
The diagnosis of ARBD can be challenging due to a lack of awareness among clinicians and the social isolation of affected individuals, who may not seek professional help. As a result, many cases of ARBD go undiagnosed. However, with proper diagnosis and treatment, the prospects for recovery are positive. Treatment typically involves abstaining from alcohol and addressing the underlying alcohol addiction.
People with ARBD often experience not only brain damage but also alcohol addiction, making treatment more complex. The addiction must be addressed alongside the memory and cognitive issues. About one in ten people with dementia has some form of ARBD, and it is likely that the condition is underdiagnosed.
ARBD can cause a range of symptoms, including poor temperature control, muscle weakness, and disturbed sleep patterns, resulting from brain shrinkage and tissue damage. Additionally, during the withdrawal phase, individuals may experience delirium, intense sweating, and behavioural problems such as agitation and hallucinations.

Alcoholic organic brain disease
Alcohol use disorder (AUD) is a medical condition characterised by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD can be mild, moderate, or severe, with severity based on the number of criteria a person meets based on their symptoms. Brain impairment in alcoholics may be conceptualised as two clinically and neuropathologically distinguishable organic brain syndromes: alcohol amnestic disorder or Korsakoff's psychosis (KP), and alcoholic dementia. Alcoholic organic brain disease may result from two interacting pathophysiological processes: nutritional (thiamine) deficiency and ethanol neurotoxicity.
Korsakoff's amnesic syndrome includes a loss of short-term memory, an inability to acquire new information, and "confabulation" (the person fills in gaps in their memory with fabrications that they believe to be true). Those with alcoholic organic brain disease may also experience peripheral neuropathy, with numbness, pain, and pins and needles affecting the body's extremities. Alcoholic dementia is another potential consequence of alcoholic brain disease, with cortical neuropathological changes associated with ethanol neurotoxicity and various secondary effects of alcoholism.
Alcohol-related brain damage (ARBD) is caused by regularly drinking too much alcohol or binge drinking over several years. ARBD is similar to dementia, such as Alzheimer's disease, and can affect memory and the ability to think clearly, particularly in those who drink much more than the recommended limit of alcohol. ARBD is often accompanied by alcohol addiction, which complicates treatment as both the addiction and the brain damage symptoms must be addressed. ARBD is typically diagnosed in people aged between 40 and 50, younger than those who develop Alzheimer's disease.
Treatment for alcoholic organic brain disease and ARBD involves addressing the addiction and brain damage symptoms. This can include behavioural treatments, such as counselling and therapy, as well as medications like naltrexone and acamprosate, which are approved by the U.S. Food and Drug Administration to help reduce drinking and prevent relapse. Inpatient and outpatient treatment options are available, and support groups can also provide assistance. Those with ARBD who stop drinking alcohol and receive good support may be able to make a partial or full recovery, regaining memory, thinking skills, and independence.

Alcohol withdrawal symptoms
The severity and duration of alcohol withdrawal vary depending on individual factors, such as the usual drinking amount and the duration of heavy drinking. For instance, the NHS recommends not drinking more than 14 units of alcohol each week. Drinking more than 25 units per week on a regular basis may start to affect one's ability to think and function properly. Binge drinking, which involves consuming large amounts of alcohol in a short period, is particularly harmful to the brain.
The symptoms of alcohol withdrawal can include:
- Mild symptoms: headache, mild anxiety, and insomnia
- Moderate symptoms: nervousness, irritability, excessive sweating, upset stomach, heart palpitations, increased blood pressure, increased heart rate, and hyperthermia (high body temperature)
- Severe symptoms: hallucinations, seizures, and delirium tremens (DTs). Delirium tremens is a severe and potentially fatal form of alcohol withdrawal that can cause serious medical issues requiring immediate medical attention.
It is important to note that alcohol withdrawal can be dangerous, and seeking medical advice is crucial. Treatment options are available to help manage the symptoms and improve comfort during the withdrawal process.

Alcohol use disorder (AUD)
AUD can cause lasting changes in the brain, making individuals vulnerable to relapse. These changes can lead to problems with memory, communication skills, and the ability to take in new information and ideas. People with AUD may also experience psychiatric symptoms such as mood changes, confusion, and hallucinations.
Treatment for AUD can vary depending on the individual's situation and severity of the disorder. It can include behavioral therapy, medication, or a combination of both. Behavioral treatments aim to change drinking behavior through counseling or talk therapy, provided by licensed therapists. Three medications have been approved by the U.S. Food and Drug Administration to help reduce or stop drinking and prevent relapse: naltrexone (oral and long-acting injectable), acamprosate, and disulfiram. These medications are non-addictive and can be used alone or in conjunction with behavioral treatments or mutual-support groups.
It is important to note that AUD treatment may need to address both the person's alcohol addiction and the symptoms related to brain impairment. Seeking professional help early can prevent a return to drinking, and people with severe AUD may need medical assistance to safely manage alcohol withdrawal symptoms.
While AUD can significantly impact an individual's life, evidence-based treatments offer hope for recovery. With treatment, many people are able to reduce their alcohol consumption or achieve abstinence.

Alcohol-related brain impairment (ARBI)
The symptoms of ARBI depend on which part of the brain has been damaged, but they can include problems with new learning, memory, thinking abilities (particularly executive functioning), and physical coordination. Other symptoms may include mood changes, confusion, hallucinations, blurred vision, poor balance, and gait (walking unsteadily). The severity of symptoms can range from mild to severe, and most people with ARBI will experience some rather than all of them.
The extent of brain damage caused by alcohol can vary depending on several factors, including age, gender, nutrition, and overall alcohol consumption. Younger people have a better chance of recovery, and complete cognitive recovery can take up to 12 months following abstinence. However, the effects of ARBI can be permanent for many individuals.
One of the most severe forms of ARBI is Wernicke-Korsakoff Syndrome (WKS), which is caused by a lack of vitamin B1 (thiamine) in the body due to long-term heavy drinking. WKS is made up of two elements: Wernicke's Encephalopathy, which involves the deterioration of brain tissue, and Korsakoff's Psychosis, which includes memory loss and an inability to acquire new information.
It is important to note that ARBI is a treatable condition, and with proper support and treatment, many symptoms can improve or even disappear over time. If an individual with ARBI stops drinking alcohol and receives good support, they may be able to achieve a partial or even full recovery, regaining their memory, thinking skills, and ability to live independently.
