Severe manifestations are often categorized under alcohol-related brain damage (ARBD), including conditions such as Wernicke-Korsakoff syndrome and alcohol-related dementia. 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. The long-term impact of alcohol on the brain encompasses a wide range of effects, varying by drinking patterns, age, genetics, and other health factors. Some cognitive improvements may be observed within weeks to months of sobriety, while long-term recovery can take years of abstinence and ongoing treatment and support.
Physical stabilisation is concerned with preventing or treating withdrawal and ensuring that any comorbid acute medical conditions are treated. This framework is split into 5 stages, which was developed from retrospective clinical studies, clinical consensus statements and studies on the rehabilitation of patients presenting with acquired, traumatic brain injury. Research (Wilson and others, 2012) has described a framework for understanding the natural history of ARBD in people who present with acute problems. Some of these episodes occur outside of clinical settings so the person remains at risk of repeated episodes of complicated withdrawal. People with alcohol dependence who continue to drink often experience unplanned episodes of withdrawal.
These changes are significant as alcohol’s effect on NMDARs could contribute to learning and memory dysfunction (see Effects of alcohol on memory). Intermittent ethanol treatment causes a decrease in expression of the dopamine receptor type 2 (D2R) and a decrease in phosphorylation of 2B subunit of the NMDA receptor (NMDAR2B) in the prefrontal cortex, hippocampus, nucleus accumbens, and for only D2R the striatum. Ethanol can trigger the activation of astroglial cells which can produce a proinflammatory response in the brain. This shows a correlation between binge drinking, poor executive functioning, and working memory. Additionally, abnormal brain metabolism, a loss of white brain matter in the frontal lobe, and higher parietal gray matter NAA levels were found. An MRI brain scan found that levels of N-acetylaspartate (NAA), a metabolite biomarker for neural integrity, was lower in binge drinkers.
- People with ARBD can present at a wide range of health and care settings including alcohol treatment services.
- It is also important to support people to make healthy lifestyle choices, such as eating healthy diets and engaging in positive activities and hobbies.
- To address these questions, this study examined the thickness of the cortex over a period of approximately 7 months among abstinent individuals with a history of alcohol use disorder following outpatient treatment.
- This discomfort, often described as misery, can motivate some people to drink alcohol again and repeat the cycle of drinking and withdrawal.
- It is vital that various levels of support are available to match the person’s needs.

Single gene mutation linked to increased alcohol tolerance and consumption
Education on the prevention of alcoholism is the best supported method of avoiding alcohol-related brain damage. This brain damage increases the risk of alcohol-related dementia, and abnormalities in mood and cognitive abilities. Alcohol related brain damage is not only due to the direct toxic effects of alcohol; alcohol withdrawal, nutritional deficiency, electrolyte disturbances, and liver damage are also believed to contribute to alcohol-related brain damage.
While these findings offer hope and insights into brain recovery during alcohol abstinence, the study — like all research — includes some limitations. These conditions are known to affect blood vessel health, and their presence appears to hinder the brain’s healing process during abstinence. The most encouraging result was the observation of significant linear recovery in cortical thickness in most brain regions studied. They were carefully selected based on specific criteria, including a diagnosis of current alcohol dependence, consistent alcohol consumption over a significant period, and various exclusion criteria related to other health conditions.
Three to six months
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.
Binge drinking, or heavy episodic drinking, can lead to damage in the limbic system that occurs after a relatively short period of time. The effects can manifest much later—mid-life Alcohol Use Disorder has been found to correlate with increased risk of severe cognitive and memory deficits in later life. Frontal lobe damage becomes the most prominent as alcoholics age and can lead to impaired neuropsychological performance in areas such as problem solving, good judgment, and goal-directed behaviors. The severity of atrophy sustained from alcohol consumption is proportional to the rate and amount of alcohol consumed during a person’s life. Uncomplicated alcoholics do not have nutritional deficiency states or liver disease, but have a reduction in overall brain volume due to white matter cerebral atrophy. If you or a loved one are wondering how long after quitting alcohol your brain heals, it may be time to get help.
A Timeline for Cognitive Recovery after Abstinence
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.
Brain structure changes may partially explain the link between screen time and ADHD
After diagnosing a person with ARBD it is important that clinicians review them on a regular basis. RCPsych college report CR185 recommends that every patient has a designated keyworker who has expertise in Brain recovery alcohol assessing and treating adults with cognitive deficits. When a clinician has identified a patient with Wernicke’s encephalopathy, they should be given immediate treatment with intravenous thiamine.
2.3 Managing ARBD
Signs of reasoning difficulties may not be obvious and can often be missed when examining people for cognitive impairment. False memories (or confabulations) often occur in people with memory deficits who will commonly appear confused when presenting at services. It can be important to provide support (such as voice notes and visual prompts) to help the person retain the information. Although the Mental Capacity Act says that people who can retain information for a short while must not automatically be assumed to lack the relevant capacity, it depends on what is necessary for the decision in question. When assessing a person’s capacity to make the decision in question, the assessor must follow the relevant legal framework.
An acute presentation is often as part of a hospital admission, where comorbid physical health issues (such as encephalopathy, delirium tremens or pancreatitis) will be the initial focus for treatment. Other health and care staff should also be alert for these signs so they can make appropriate referrals. Practitioners should also provide people with information on what services can offer in a way that they can understand.

Alcohol is a powerful reinforcer in adolescents because the brain’s reward system is fully developed while the executive function system is not, and because there is a powerful social aspect to adolescent drinking. The developing adolescent brain is particularly vulnerable to alcohol-related harm. The person feels alcohol is needed for temporary relief from discomfort and emotional pain.
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.
- PET and SPECT studies have confirmed and expanded previous findings stating that the prefrontal cortex is particularly susceptible to decreased metabolism in alcohol abusing patients.
- The US study found those who quit drinking gain cortical thickness over time, faster in the first month and continuing over 7.3 months, at which point thickness is comparable to those without AUD.
- OK, so to stay motivated as you work through recovery,remember that though it’s rarely easy, if you can quit and stay quit your braincan recover enormously and you can look forward to retaining the intellectualcapacities of your pre-alcohol years.
- One of the proposed mechanisms for alcohol’s neurotoxicity is the production of nitric oxide (NO), yet other studies have found alcohol-induced NO production to lead to apoptosis (see Neuroinflammation section).
- Clinically, people with AUD showed worse cognition, higher anxiety and depression, and poorer sleep than controls.
- Staff in community alcohol treatment services should routinely carry out a brief cognitive assessment as part of comprehensive assessment.
These assessments can alert staff to the possibility of cognitive impairment that can then be further investigated by specialists. It is important that brief cognitive assessments include tests of frontal lobe function. There are several formal assessment tools that staff can use to identify the possibility of cognitive impairment. This would need to be a service with specialist expertise in neurological conditions or cognitive impairment. In many parts of the UK, care pathways for people with ARBD are not well established and this can lead to people not receiving the care they need when they need it.
People with alcohol related brain damage
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.
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.
