Flexible engagement approaches such as assertive outreach can help to support people who are unlikely to attend service bases (see chapter 9 on assertive outreach). The Royal College of Psychiatrists recommends reassessing a patient’s cognitive function 3 months after the initial assessment. It is important that clinicians investigate the main cause of any cognitive impairment and distinguish ARBD from other conditions. However, ARBD is consistently underdiagnosed because of a lack of awareness among clinicians (Wilson and others, 2012) and many people are not identified until their cognitive impairment becomes severe. Supported accommodation can help some people with ARBD to improve their day-to-day function and reduce their likelihood of returning to harmful drinking.
- Although the use of brief cognitive assessment tools can alert the clinician to the possibility of ARBD in a person at risk, they cannot confirm this.
- Clinicians should treat Wernicke’s encephalopathy as an emergency and manage the person in an acute medical setting.
- Heavy drinking causes alcohol-related brain damage, with alcohol acting as a direct neurotoxin to nerve cells, while low levels of alcohol consumption can cause decreases in brain volume, regional gray matter volume, and white matter microstructure.
- Over the course of 7 months of abstinence, individuals with alcohol use disorder experienced significant improvements in their brain structure.
During this time, someone who lacked mental capacity to make decisions about various aspects of their care due to ARBD may regain capacity. Cognition can begin to improve as soon as the person stops drinking and can continue to improve substantially for 3 to 6 months if they remain abstinent. People with ARBD need to remain abstinent from alcohol for their cognition to improve as a result of not being exposed to the direct toxic effects of alcohol. Wernicke’s encephalopathy is an acute medical emergency where alcohol withdrawal and lack of vitamin B1 causes inflammation of the brain.

People with ARBD may have experienced up to 20 years of retrospective memory loss and may not have any significant understanding of their harmful drinking and that it has contributed to their current situation. Long-term memory problems are common among people with Wernicke-Korsakoff syndrome. The person may be able follow a conversation and hold information long enough to weigh it up and make a decision, but might forget the content of the conversation (and the decision made) a few hours later.
Modern neuroimaging techniques in particular have revolutionized the understanding of alcohol-related brain damage. If this hyperexcitability state occurs multiple times, kindling and neurotoxicity can occur leading to increased alcohol-related brain damage. Repeated detoxifications (“kindling”) can worsen withdrawal symptoms and amplify brain damage through hyperexcitability and excitotoxicity, leading to more severe cognitive and emotional dysfunction over time, particularly in the prefrontal cortex. It is unclear how the frequency and length of binge drinking sessions impacts brain damage in humans. Serious complications include irreversible brain damage, psychiatric disorders (e.g., depression, anxiety), and increased risk of other neurodegenerative conditions, such as Alzheimer’s disease. Complicated alcoholics may have liver damage that impacts brain structure and function and nutritional deficiencies “that can cause severe brain damage and dysfunction”.
A full assessment of activities of daily living should take place. It is important to reassess their functional ability and the amount of support they will need, encouraging autonomy but ensuring safety. This will strengthen their informal community support structure for times when professionals are not so closely involved. As with all medication, the clinician needs to obtain the person’s informed consent before they start the medication, and they will need to get their consent on a regular basis. Staff need to take a persistent and consistent approach to encouraging people to carry out tasks and participate in activities. For some people, ARBD can result in apathy and problems with motivation.
Causality along the gut-brain route was supported in GF mice. Scientists trace alcohol’s impact from the gut to the brain, uncovering microbial changes that weaken the blood-brain barrier, and a probiotic that helps repair it. Gender and parental history of alcoholism and binge drinking has an influence on susceptibility to alcohol dependence as higher levels are typically seen in males and in those with a family history.
Section 4 of the Mental Capacity Act 2005 sets out a checklist of factors that decision makers must work through in deciding what is in a person’s best interests. While a formal diagnosis may help to establish if the person has an impairment or disturbance, a formal diagnosis is not necessary for the purposes of the Mental Capacity Act. You can find information on the legislation and statutory guidance on mental capacity in annex 1. People living in residential environments on the basis of care needs may receive psychosocial interventions as part of an ARBD rehabilitation package. Ongoing training and education to develop employment and life skills as well as support to manage their own finances may be appropriate.
Chronic drinking weakens the blood-brain barrier through the gut
This means that your brain can generate new cells to replace damaged ones, contributing to its recovery. When you abstain from alcohol, especially for an extended period, your brain starts to repair and rebuild damaged neural connections. The extent of recovery depends on various Brain recovery alcohol factors, including the severity and duration of alcohol abuse, individual differences, and the presence of any underlying conditions.
Correlation networks linked differential taxa, including Faecalibacterium, with several altered metabolites, but did not directly establish relationships with cognitive scores, suggesting microbiome–metabolite patterns that may accompany neurobehavioral differences. Clinically, people with AUD showed worse cognition, higher anxiety and depression, and poorer sleep than controls. Fecal microbiota transplantation (FMT) from AUD patients or healthy donors was performed in GF mice. BBB integrity was assessed by 20-kilodalton (kDa) fluorescein isothiocyanate (FITC)-dextran leakage and by tight-junction proteins zonula occludens-1 (ZO-1), occludin, claudin-5 by western blot and immunofluorescence. Participants with neuropsychiatric, infectious, neoplastic, autoimmune, or digestive diseases and those recently exposed to antibiotics, probiotics, prebiotics, or prolonged abstinence were excluded. The investigators enrolled 30 adult males with Alcohol Use Disorder (AUD) using Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria and 30 healthy male controls.
2.4 Evidence for preventing and treating ARBD
This requires establishing joined up, multidisciplinary, person-centred pathways that take account of the complex range of factors involved in preventing and managing ARBD. If clinicians can identify it at an early stage and the person can stay abstinent, then the prognosis can be good. These different causes can all result in ARBD and there will be similarities in how the person presents regardless of the cause of ARBD. Executive functions are a range of cognitive processes that include planning, organising, prioritising, working memory and self-regulation. This is so people have access to appropriate interventions for the full spectrum of ARBD.
9.4 Practical suggestions for assessing the mental capacity of a person with ARBD to make a decision
Moderate recovery may occur with abstinence, while chronic excessive drinking may trigger irreversible brain cell loss. The brain has some capacity to regenerate and repair damaged cells, but the extent of this regeneration depends on factors such as the amount and duration of alcohol use. Seeking professional help and support during the recovery process can optimize your brain’s chances of regaining its health and functionality. Reversing brain damage from alcohol largely depends on various factors, including the extent and duration of alcohol abuse, individual physiology, and lifestyle changes. “The relationship between the improvements in cortical thickness, psychiatric conditions and symptoms and cognitive function and quality of life measures need to be examined.”
- Lesions, or brain abnormalities, are typically located in the diencephalon which result in anterograde and retrograde amnesia, or memory loss.
- Long-term memory problems are common among people with Wernicke-Korsakoff syndrome.
- Binge drinking, or heavy episodic drinking, can lead to damage in the limbic system that occurs after a relatively short period of time.
- They may find it difficult to resist situational cues, such as triggers to drinking in stressful situations.
- The volume of the corpus callosum, a large white matter tract that connects the two cerebral hemispheres, is shown to decrease with alcohol abuse due to a loss of myelination.
4.3 Advice against suddenly stopping drinking for people with alcohol dependence
It is helpful to give people simple repeated instructions about carrying out tasks and avoid giving them unnecessary information. For example, staff may need to prompt and help people to make use of their journal. You can promote functional recovery through maintaining a journal, planning activities and learning skills. A therapeutic rehabilitation programme aims to gradually improve a person’s skills for daily living as their cognition improves. There are a number of principles and interventions that should be considered during the psychosocial assessment phase.
Higher social media engagement linked to reduced performance on cognitive assessments
A potential cause of chronic alcoholic cerebellar dysfunction is an alteration of GABA-A receptor. This integration between the two cerebral hemispheres and cognitive function is affected. The volume of the corpus callosum, a large white matter tract that connects the two cerebral hemispheres, is shown to decrease with alcohol abuse due to a loss of myelination. Research is still being conducted to determine whether there is a direct link between excessive alcohol consumption and Alzheimer’s disease. It was found that a heavy two-day drinking binge caused extensive neurodegeneration in the entorhinal cortex with resultant learning deficits in rats.
Alcohol alters microbes, metabolites, and cognitive scores
“High impulsivity has also been found in families with alcoholism, suggestive of a genetic link. Thus, the genetics of impulsivity overlaps with genetic risks for alcohol use disorder and possibly alcohol neurodegeneration”. The impulsivity and sensation seeking seen in adolescence may lead to increased alcohol intake and more frequent binge drinking episodes leaving adolescents particularly at risk for alcoholism. Some of these cognitive effects, such as learning impairments, may persist into adulthood. Compared to adults, adolescents exposed to alcohol are more likely to exhibit cognitive deficits (including learning and memory dysfunction). These changes may make adolescents especially susceptible to the harmful effects of alcohol. The identification of Wernicke’s encephalopathy and Korsakoff’s psychosis linked alcohol to specific brain disorders.
Yes, brain cells can regenerate to some extent after alcohol consumption, particularly in regions such as the hippocampus. This enables the brain and nervous system to recover from damage and adapt to new patterns of thinking and behavior. Get dual-diagnosis treatment for SUD and mental health In addition, individuals with certain cardiovascular risk factors, collectively referred to as “atherogenic conditions,” experienced less recovery in specific regions, such as the anterior frontal, inferior parietal, and lateral/mesial temporal regions were particularly affected. This suggests that the amount and duration of alcohol consumption may influence the pace of recovery.

Emmerson C and Smith J. Evidence-based profile of alcohol related brain damage in Wales (PDF, 540KB). For example, this might be because you are proposing a care plan to restrict alcohol consumption and there is a good reason to believe the person may lack capacity to consent. Dedicated ARBD services are rare in the UK, so people with ARBD will often have their health and social care provided by a variety of different services.
8 Multidisciplinary, multi-agency community support in the longer term
By demonstrating that AUD microbiota induce barrier breakdown in GF hosts after FMT, it shifts the gut-brain axis from association to causation. However, the microbial shifts represent alterations rather than complete “restoration” toward healthy community structure. Because SCFAs can strengthen endothelial junctions, alter nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling, and reduce neuroinflammation, these metabolite changes offer a plausible mechanism for recovery.
