Alcohol-related brain damage (ARBD) or alcohol-related brain injury (ARBI) is a brain disorder caused by drinking too much alcohol over a prolonged period. ARBD/ARBI can cause memory loss, impaired judgment, and difficulties with coordination and balance. It can also lead to alcohol dependence and addiction. Those with ARBD/ARBI are also at a higher risk of repeated head injuries, as alcohol intoxication is a major risk factor for traumatic brain injuries (TBI). The effects of ARBD/ARBI can be permanent, but if the excessive consumption of alcohol is stopped, about 25% of cases recover completely, and 50% show partial recovery.

What You'll Learn
Alcohol-related brain damage (ARBD)
ARBD can be difficult to diagnose, and many cases may go undetected due to social isolation, lack of engagement with healthcare professionals, and limited knowledge about the condition among clinicians. However, with proper diagnosis and treatment, the prospects for recovery from ARBD are positive. Treatment typically involves abstaining from alcohol, improving diet and nutrition, and taking high doses of vitamin B1 (thiamine) to improve brain function. Brain scans have shown that some of the damage caused by excessive drinking can be reversed with abstinence.
People with ARBD may experience mild cognitive impairment (MCI) or more severe problems with memory and thinking, sometimes referred to as alcohol-related "dementia" or Wernicke-Korsakoff syndrome. They are also at a higher risk of repeated head injuries due to falls or accidents while intoxicated. The condition predominantly affects individuals between the ages of 40 and 50, which is younger than the typical onset age for common types of dementia.
The treatment for ARBD should be tailored to the individual's specific needs. Support from family and friends is crucial for improving outcomes. Additionally, legal arrangements, such as the Mental Capacity Act 2005 and Lasting Power of Attorney (LPA), can help make decisions on behalf of individuals who lack the mental capacity to do so themselves.
It is important to note that continued alcohol consumption and poor diet can lead to the progression of ARBD. Therefore, addressing alcohol addiction and providing adequate support are vital for the recovery process.

Alcohol-related brain injury (ARBI)
ARBI can be caused by the toxic effects of alcohol on nerve cells, which can lead to brain cell death and shrinkage of brain tissue. Alcohol can also damage blood vessels in the brain and cause high blood pressure, increasing the risk of stroke. Alcohol prevents the body from absorbing thiamine (vitamin B1), which is essential for brain health. A lack of thiamine can lead to Wernicke's encephalopathy, an intense swelling of the brain that causes jerky eye movements, double vision, and muscle movement problems.
ARBI is most common in men over 45 with a long history of alcohol abuse. However, anyone who regularly consumes alcohol at risky levels can develop ARBI, and the likelihood increases with the duration and amount of alcohol consumption. Recovery from ARBI is possible, especially if treatment is sought early, and drinking is stopped. Treatment options include support groups, such as Alcoholics Anonymous, and medical treatment by doctors, neuropsychologists, or neurologists. Doctors may prescribe multivitamins, especially thiamine, to reduce the risk of further brain injury.
It is important to note that ARBI is not limited to physical damage to the brain but also includes alcohol addiction, which can complicate treatment. Professionals need to address both the addiction and the cognitive symptoms related to memory and thinking.

Traumatic brain injuries (TBI)
Alcohol-related brain damage (ARBD) or alcohol-related brain injury (ARBI) is caused by a person regularly drinking too much alcohol or binge drinking over several years. ARBD does not always get worse over time, and people with ARBD can make a partial or full recovery if they stop drinking alcohol and receive good support. However, if a person with ARBD continues to drink, they are at risk of more serious brain damage.
Traumatic Brain Injuries (TBIs) are characterised by neurological dysfunction caused by a bump, blow, or penetrating injury to the brain. There is a strong bidirectional relationship between TBI and Alcohol Use Disorder (AUD). Alcohol intoxication is a major risk factor for TBI, and a substantial proportion of TBIs occur in intoxicated individuals.
The relationship between TBI and AUD is complex. Firstly, alcohol intoxication increases the risk of sustaining a TBI. This may be due to impaired coordination and judgment, leading to accidents or injuries. Secondly, TBI can serve as a risk factor for the development or exacerbation of AUD. Injury to the brain can result in affective, cognitive, and psychosocial impairments that promote alcohol misuse. For example, people with frontal lobe injuries often have deficits in decision-making, which may contribute to problematic drinking behaviours. Additionally, there is an inverse relationship between TBI and AUD, where alcohol use after a TBI can negatively impact rehabilitation outcomes, increase the risk of additional head injuries, and impair functional recovery.
The presence of both TBI and AUD can lead to poorer long-term outcomes. Continued alcohol use after a TBI can further damage vulnerable neural structures and impair cognitive functioning. It can also interfere with the efficacy of prescribed medications and impair wound healing. Furthermore, individuals with TBI who meet the criteria for AUD are at an increased risk of suicide.
The exact neurobiological links between TBI and AUD are still being investigated, and future research should focus on developing screening and treatment methods to minimise the harm associated with drinking alcohol after a TBI.

Alcohol withdrawal syndrome
Alcohol-related brain damage (ARBD) or alcohol-related brain injury (ARBI) is caused by a person regularly drinking too much alcohol or binge drinking over several years. Those who suffer from ARBD are usually aged between 40 and 50. ARBD can lead to alcohol withdrawal syndrome, a set of symptoms that can develop if a person stops or significantly reduces alcohol intake after long-term use.
Symptoms
The symptoms of alcohol withdrawal syndrome range from mild to severe, with the most severe being life-threatening. They include insomnia, tremulousness, seizures, and delirium tremens. Alcohol withdrawal syndrome can be diagnosed through a physical exam, the patient's symptoms, alcohol use history, and medical history. It is important to be honest about alcohol use and other substance use so that healthcare providers can give the best care.
Treatment
Treatment for alcohol withdrawal syndrome involves medication and comprehensive treatment programs. Benzodiazepines are the medication of choice and can be administered on a fixed or symptom-triggered schedule. Carbamazepine is an effective alternative with little potential for abuse and can decrease the craving for alcohol after withdrawal. Baclofen has also been shown to reduce craving in alcohol-dependent patients. Other medications that can be used as adjuncts to benzodiazepines include haloperidol, beta-blockers, clonidine, and phenytoin.
Prevention
The best way to prevent alcohol withdrawal syndrome is to avoid alcohol altogether. If a person thinks they are developing alcohol use disorder, it is important to seek professional help as soon as possible. The sooner a person gets treatment, the better.

Alcohol-related dementia
Alcohol-related brain damage (ARBD) or alcohol-related brain injury (ARBI) can lead to alcohol-related dementia. This is caused by a person regularly drinking too much alcohol or binge drinking over several years. Binge drinking is defined as consuming more than 14 units of alcohol in a single week. Those with ARBD are usually aged between 40 and 50, which is younger than the typical age of onset for more common types of dementia.
The symptoms of alcohol-related dementia vary from person to person, but they often include memory loss and difficulty with complex tasks, such as managing finances. It can also cause physical symptoms, such as an unsteady gait and a higher likelihood of falling, even when sober. This is because alcohol damages the part of the brain that controls balance, coordination, and posture.
To diagnose alcohol-related dementia, a doctor will perform a physical examination and take a detailed history of the person's symptoms and how they are affecting their life. They may also ask about problems with mood and conduct a paper-based test to check for memory and thinking problems. A brain scan may also be necessary to rule out other causes of symptoms.
Treatment for alcohol-related dementia involves addressing both the person's alcohol addiction and the symptoms related to memory and thinking. Good nutrition is important, and doctors may prescribe multivitamins, especially thiamine, to reduce the risk of further brain injury. Support from loved ones is crucial, as those with alcohol-related dementia may require assistance with daily tasks.
