Alcohol acts on the nerve cells of the brain and disrupts the communication between nerves cells and other cells of the body. Alcohol suppresses the activities of certain nerve pathways, eventually making a person appear sluggish, lethargic and slow-moving.

Can your brain cells recover from alcohol?
Home Blog How long does brain recovery take after alcohol abuse?
Studies into the effects of alcohol on the brain have shown that the brain is able to repair itself remarkably quickly after stopping drinking. Research indicates that the impact on the brain’s grey matter, which shrinks from alcohol abuse, begins reversing within two weeks when chronic alcohol abusers become abstinent.
“Shrinkage of brain matter, and an accompanying increase of cerebrospinal fluid, which acts as a cushion or buffer for the brain, are well-known degradations caused by alcohol abuse,” explained Gabriele Ende, professor of medical physics in the Department of Neuroimaging at the Central Institute of Mental Health.
“This volume loss has previously been associated with neuropsychological deficits such as memory loss, concentration deficits, and increased impulsivity.” The shrinking of any portion of the brain is worrying, but the damage done by alcohol is especially concerning because some of the shrinkage is probably due to cell death.
- Once brain cells die, the effect of the brain damage is permanent.
- Thankfully, some of the changes in the alcoholic brain are due to cells simply changing size in the brain.
- Once an alcoholic has stopped drinking, these cells return to their normal volume, showing that some alcohol-related brain damage is reversible.
“We found evidence for a rather rapid recovery of the brain from alcohol induced volume loss within the initial 14 days of abstinence,” said Ende. “Although brain shrinkage, as well as a partial recovery with continued abstinence have been elaborately described in previous studies, no previous study has looked at the brain immediately at the onset of alcohol withdrawal and short term alcohol recovery.
Our study corroborates previous findings of brain volume reduction for certain brain regions.” The alcohol recovery timeline can be fairly short in certain areas. While different areas of the brain recover at different rates, the initial findings of the study show that much of the lost functionality in the brain returns quickly.
“The function of the cerebellum is motor co-ordination and fine tuning of motor skills,” Ende explained. “Even though we did not assess the amelioration of motor deficits in our patients quantitatively, it is striking that there is an obvious improvement of motor skills soon after cessation of drinking, which is paralleled by our observation of a rapid volume recovery of the cerebellum.
Higher cognitive functions, such as divided attention, which are processed in specific cortical areas, take a longer time to recover and this seems to be mirrored in the observed slower recovery of brain volumes of these areas.” These findings may drastically alter how many alcohol recovery centres work.
Currently, alcohol abuse treatment often only covers the first phase of detox. This lasts between a few days to a week. However, for those struggling with addiction, life after alcohol requires an ongoing commitment to maintain sobriety and a healthier way of life.
- In the short term, treatment can quickly help to address other effects of alcohol in the brain, such as alcohol brain fog.
- This refers to issues such as difficulty concentrating, confusion and an inability to think clearly.
- The new research shows that it takes at least two weeks for the brain to start returning to normal, so this is the point at which the alcohol recovery timeline begins.
Until the brain has recovered, it is less able to suppress the urge to drink. This is because the alcohol has impaired the brain’s cognitive ability. Ende and her colleagues now believe that any proper alcohol abuse treatment should last for a minimum of two weeks.
What nerve damage is caused by alcohol abuse?
Alcoholic neuropathy involves coasting caused by damage to nerves that results from long term excessive drinking of alcohol and is characterized by spontaneous burning pain, hyperalgesia and allodynia. The mechanism behind alcoholic neuropathy is not well understood, but several explanations have been proposed.
How does alcohol affect the nerve cells in the brain?
Abstract – Alcohol abuse is a major health problem worldwide, resulting to extensive admissions in many general hospitals. The overall economic cost of alcohol abuse is enormous worldwide. As a small molecule, alcohol can easily cross membrane barriers and reach different parts of the body very quickly.
- Attainment of its equilibrium concentration in different cellular compartments depends on the respective water content.
- Alcohol can affect several parts of the brain, but, in general, contracts brain tissues, destroys brain cells, as well as depresses the central nervous system.
- Excessive drinking over a prolonged period of time can cause serious problems with cognition and memory.
Alcohol interacts with the brain receptors, interfering with the communication between nerve cells, and suppressing excitatory nerve pathway activity. Neuro-cognitive deficits, neuronal injury, and neurodegeneration are well documented in alcoholics, yet the underlying mechanisms remain elusive.
Are nerve cells destroyed by alcohol abuse?
What can alcohol abuse do to the brain? – Alcohol is an irritant to all body tissue, from where it comes in to where it goes out. Alcohol does kill brain cells. Some of those cells can be regenerated over time. In the meantime, the existing nerve cells branch out to compensate for the lost functions.
This damage may be permanent. Moreover, after a certain age, the connections between neurons begin to prune back. In a brain damaged by alcohol, we may see early-onset dementia. Age makes a difference. The brain is developing until about age 26. This is especially true between the ages of 13 and 26, when there’s explosive growth in the prefrontal cortex.
People that start drinking heavily at this time are more prone to cognitive problems like impulsivity, emotional dysregulation, anxiety and depression.
How do you know if alcohol has permanently damaged your brain?
Read all our factsheets and publications on alcohol-related brain damage in one place. Read the factsheets The symptoms of ARBD vary, but include problems with cognitive functioning (thinking and understanding) and memory, alongside physical symptoms.
Memory loss – a person is unable to remember directions to familiar places or has trouble remembering appointments or recalling what they’ve just done or should be doing.
Difficulty with familiar tasks – a person may struggle with an everyday task like using their phone, or be confused about the layout of their home or how to prepare a meal.
Difficulty in processing new information – not being able to recall times, dates, appointments they’ve recently been given, or to remember people they’ve just met.
Depression and irritability – this can also include apathy, a lack of interest in people or events and a lack of spontaneity or motivation.
Poor judgement and loss of inhibition – a person may be too trusting of strangers or respond inappropriately, for example by removing their clothes in public.
Problems with language – there may be difficulties in remembering words or the names of friends and family, or problems like forgetting the end of a sentence halfway through.
Erratic behaviour – carers of people with ARBD often find this the most difficult thing to cope with. A person may have rapid mood swings, become aggressive or even violent, or otherwise behave out of character. They may also have no insight into how they’re behaving and the effect it is having on themselves or others, making them appear harsh and uncaring.
Difficulty concentrating – it can be hard for people with ARBD to focus on one thing for more than a few minutes, which can make everyday tasks difficult.
Poor choices and decision-making – a person may not see any reason to think about changing their drinking and may not seek or accept help. They may have difficulty in weighing up options or making sensible decisions. They may also be vulnerable to manipulation, coercion and abuse by others.
There may also be physical signs of the damage to the body and its control systems, such as:
Damage to the liver, stomach and pancreas – all of which can affect brain function.
Pins and needles and numbness or burning sensation in arms and legs – this can increase the risk of falls and accidents.
Slow, wide, stumbling gait (ataxia) – this can make it difficult for someone to walk, and they may find balancing difficult.
Poor temperature control, muscle weakness and disturbed sleep patterns – these are all caused by shrinkage of the brain and by tissue damage.
Sometimes, these symptoms will build gradually and could be noticeable to family and friends long before the person with ARBD realises that something is wrong. Symptoms may be misunderstood as effects of stress or growing older, or even that the person is just drunk – indeed, one reason ARBD may not be diagnosed in a drinker is that its symptoms can appear very much like drunkenness.
In other cases, such as Wernicke-Korsakoff’s Syndrome, or after a severe brain injury, the symptoms will appear suddenly and may be quite severe. Symptoms may also appear when someone is withdrawing from alcohol. The story below, from Chris, a lady with ARBD, gives just one example of what it’s like to live with one form of this condition: “I didn’t think I drank that much, the odd glass in an evening with my husband, but I didn’t notice my consumption gradually increasing and I definitely didn’t know the damage it would do to my mind and body.
I had always been fit and healthy; I had no reason to be concerned. It started gradually at first, stumbling occasionally, forgetting things and then all of a sudden it felt like I lost control of my left side. I couldn’t walk properly; my leg wouldn’t listen to what I wanted it to do, no matter how hard I tried.
- It felt like I’d had a stroke: in the end it was so bad that I resorted to crawling on all fours at home.
- I looked up my symptoms and thought I may even have Parkinson’s.
- I didn’t even know that Alcohol-Related Brain Damage existed until somebody said I had it.
- Eventually I was diagnosed with Cerebellar Disease after a severe B12 deficiency, and was told the extent of my recovery would depend on the length of time this had been going on.
It has taken me seven long years to get nearly back to normal. I still go to physiotherapy now, but only I know what’s happened to me.” The most severe form of ARBD is known as Wernicke-Korsakoff’s Syndrome (WKS), and was named after the two doctors who first recognised it.
It is caused by a lack of vitamin B1 (thiamine) in the body, which in turn is a result of long-term heavy drinking. In the past, Wernicke-Korsakoff’s Syndrome (WKS) was used as an umbrella term to describe all types of ARBD and alcohol-related dementias. However, the term Alcohol-Related Brain Damage (or Alcohol-Related Brain Impairment) is a much more useful term, as WKS is actually a very specific form of ARBD.
WKS is made up of two separate elements: Wernicke’s Encephalopathy and Korsakoff’s Psychosis. Wernicke’s Encephalopathy is a deterioration of brain tissue, and the symptoms include confusion and disorientation, numbness in the hands and feet, rapid random eye movements (sometimes called ‘dancing eyes’), blurred vision, and poor balance and gait (walking unsteadily).
It should be treated as a medical emergency and can be effectively treated with large doses of thiamine, if caught early. People with Wernicke’s Encephalopathy often appear drunk, even if they’ve had very little to drink. Many patients who experience Wernicke’s Encephalopathy go on to develop Korsakoff’s Psychosis.
The symptoms of this include memory loss, apathy, and confusion about where they are and about the passage of time. A swift diagnosis and early treatment can often reverse these symptoms. For advice on living with someone with ARBD, see our handbook for carers: Road to Recovery,

Is a long term effect of alcohol damaged brain cells?
Image Diffusion tensor imaging (DTI) of fiber tracks in the brain of a 58-year-old man with alcohol use disorder. DTI maps white-matter pathways in a living brain. Image courtesy of Drs. Adolf Pfefferbaum and Edith V. Sullivan. Alcohol interferes with the brain’s communication pathways and can affect the way the brain looks and works.
Can alcohol cause permanent nerve damage?
– Alcoholic neuropathy is a severe condition that can lead to chronic pain, loss of some bodily functions, and permanent disability. However, recognizing the symptoms and seeking medical attention early can minimize the impact of the condition. A person can improve their outlook by significantly reducing or cutting off their alcohol intake and ensuring that they are receiving the right balance of nutrients.
Can nerve damage from alcohol be repaired?
However, some people with alcohol-related neuropathy can improve through abstinence and alcohol abuse treatment. In other cases, though, the neurological deficits associated with alcoholic neuropathy can be permanent, and it can worsen if a person keeps drinking.
What are 4 negative effects of alcohol on the nervous system?
The central nervous system (CNS) is the major target for adverse effects of alcohol and extensively promotes the development of a significant number of neurological diseases such as stroke, brain tumor, multiple sclerosis (MS), Alzheimer’s disease (AD), and amyotrophic lateral sclerosis (ALS).
How many brain cells are killed by alcohol?
– Alcohol doesn’t kill brain cells, but it does have both short- and long-term effects on your brain, even in moderate amounts. Going out for happy hour a few nights a month likely won’t cause any long-term damage. But if you find yourself drinking heavily or binge drinking often, consider reaching out for help.
How does alcohol affect the myelin?
Ethanol, by activating the TLR4 signaling pathway in astroglial and microglial cells, triggers the release of inflammatory mediators and cytokines (iNOS, COX-2, IL-1β, TNF-α), which leads to brain damage and apoptotic neuronal death, and also to myelin disarrangements and cognitive impairments.
What are 4 long term effects of alcohol on the brain?
What Effects can Alcohol Have on My Mental Health? – People may experience improved social interaction or general feelings of well-being with moderate alcohol consumption. But it’s important to understand that alcohol use can pose a risk to someone’s mental health, overall mood, and daily cognitive functioning due to its impact on brain chemicals. Cognitive effects of alcohol use may include memory loss, problems with learning, dementia, and severely hindered mental functioning in most severe cases.10 Seeking alcohol addiction treatment is the first step in preventing or reducing the negative effects of alcohol on the brain.
How to heal the brain after years of drinking?
Helping your brain recover after alcohol and other drug use – You can support your brain (and body) to recover and improve brain health and neuroplasticity, through:
regular exercise, which can increase the size of the hippocampus – a part of the brain vulnerable to AOD use. It’s also good for mental and physical healthpracticing mindfulness, such as meditation, which can help strengthen brain circuits damaged by AOD useeating a balanced and nutritious diet to help offset vitamin and mineral deficiencies that typically occur with AOD useregular sleep, which is when the brain flushes out toxins. Establishing good sleep habits can help brain recovery.7-9

Understanding Wernicke-Korsakoff Syndrome – So, what—exactly—is a “wet brain?” According to the National Organization for Rare Disorders, Wernicke-Korsakoff syndrome is really two different disorders. Wernicke’s is a neurological disease characterized by “confusion, the inability to coordinate voluntary movement and eye (ocular) abnormalities,” while Korsakoff’s is a mental disorder characterized by disproportionate memory loss.
Because the ability to form new memories is almost nonexistent, a person with Wernick-Korsakoff syndrome might be too confused to find their way out of a room or remember what’s been said just 20 minutes before, consistently repeating questions or comments during a conversation. As summarized by healthline.com, “Wernicke’s disease affects the nervous system and causes visual impairments, a lack of muscle coordination, and mental decline.
If Wernicke’s disease is left untreated, it can lead to Korsakoff syndrome. Korsakoff syndrome permanently impairs memory functions in the brain.” How does wet brain kill you? Without thiamine, the tissue of the brain begins to deteriorate. Korsakoff’s syndrome dementia affects not just the brain, but also the cardiovascular and central nervous system.
Once a person has been diagnosed with end stage alcoholism, life expectancy can be as limited as six months. In many ways, a person struggling with alcohol addiction and showing symptoms of second-phase wet brain acts much like someone with Alzheimer’s disease. Based on statistics from the National Institute on Alcohol Abuse and Alcoholism, 90 percent of alcoholics suffering from stage 1 symptoms go on to develop stage 2, with some overlap between the stages and symptoms.
Symptoms: Stage 1
Drowsiness and paralysis of eye movements Rapid, tremor-like eye movements Visual and auditory hallucinations Ataxia (unsteady gait caused by weakness in limbs or lack of muscle coordination) Affected sense of smell Delirium Tremens (the shakes) Confusion, agitation or inattentiveness
Symptoms: Stage 2
Alcohol-related memory loss (from mild to severe) Disorientation with regard to time and place Distorted or misinterpreted memories Made up or invented information to compensate for poor memory Mental disturbances Dementia Hallucinations Impaired ability to learn new tasks Coma (advanced stages)
About 1-2 percent of the population is affected by wet brain, according to research by the National Organization for Rare Disorders. Men suffering from alcohol abuse, between 30-70 years, are slightly more affected than women of the same age. Of those who develop Wernicke-Korsakoff syndrome, about 25 percent require long-term treatment in a hospital setting.
There’s no single test for the syndrome, but a good indication, particularly when disorientation and confusion are apparent, is testing vitamin B1 levels in the blood. Research conducted by the Alzheimer’s Association estimates that when caught early enough, approximately 25 percent of people will recover, 50 percent will improve and 25 percent will stay the same.
However, once the syndrome has progressed to the point of no return—no new memories or experiences, no reversing the symptoms—the disease is generally fatal. The grim reality of chronic alcohol abuse is that the body can only handle so much; and Wernicke-Korsakoff syndrome is a tragic, heartbreaking consequence of the abusive nature of alcoholism.
Does alcohol destroy brain GREY matter?
Diminished Gray Matter in the Brain – Substance abuse of any kind can have a detrimental effect on the body. In regard to alcohol, it significantly affects the tissues in the brain. Research suggests that gray matter in the brain reduces due to high amounts of alcohol.
- Alcohol-dependent patients were studied and scanned within 24 hours of detoxification and abstinence; tissue volume was observed to be smaller in alcohol-dependent patients than in the non-alcohol-alcohol-dependent patients.
- This shows that alcohol use makes gray matter in the brain shrink over time.
The brain is about 40% gray matter. This is the part of the brain that is essential for attention, memory, and thought, It contains neurons that also deal with motor control and coordination, which explains why long-term alcohol abuse is characterized by loss of memory and attention deficits.
- Studies in college-age young adults show that heavy alcohol use results in accelerated grey matter volume,
- It is a common misconception that drinking excessively “kills brain cells”; this is not true.
- However, excessive drinking does damage neurons, which can make it difficult for them to relay messages to one another.
This is why brain matter is so essential for functioning. This tissue contains these precious neurons that need to relay important messages. Just because it doesn’t “kill” brain cells doesn’t mean it’s any less damaging to the brain. It is possible to save these tissues in the brain by reducing or stopping alcohol use and abuse.
Can a long term effects of alcohol on the brain be cognitive deficits?
How Does Alcohol Affect the Brain? – Alcohol has a profound effect on the complex structures of the brain. It blocks chemical signals between brain cells (called neurons), leading to the common immediate symptoms of intoxication, including impulsive behavior, slurred speech, poor memory, and slowed reflexes,1,2 If heavy drinking continues over a long period of time, the brain adapts to the blocked signals by responding more dramatically to certain brain chemicals (called neurotransmitters).
After alcohol leaves the system, the brain continues over activating the neurotransmitters, causing painful and potentially dangerous withdrawal symptoms that can damage brain cells.1,2,3 This damage is made worse by drinking binges and sudden withdrawal.1,4 Alcohol’s damage to the brain can take several forms.
The first is neurotoxicity, which occurs when neurons over react to neurotransmitters for too long. Too much exposure to a neurotransmitter can cause neurons to eventually “burn out.” 1 Since neurons make up the pathways between different parts of the brain, when they begin burning out, it can cause noticeable slowing in the reactions of these pathways.
In addition to pathway damage, brain matter itself is also damaged by heavy alcohol use. People with alcohol dependence often experience “brain shrinkage,” which is reduced volume of both gray matter (cell bodies) and white matter (cell pathways) over time,1,2,5 There are some subtle differences in how brain damage occurs in men and women, but regardless of gender, loss of brain matter increases with age and amount of alcohol consumed.2,6,7 What are the observable effects of this damage? Since alcohol affects a large portion of the brain, many different kinds of cognitive impairment can occur as a result of heavy drinking, including problems with verbal fluency and verbal learning, processing speed, working memory, attention, problem solving, spatial processing, and impulsivity.8,9,10 Parts of the brain relating to memory and “higher functions” (e.g., problem solving and impulse control) are more susceptible to damage than other parts of the brain, so problems in these areas tend to be worse than others.5,11,12 Adolescents are especially at risk for long-lasting or permanent damage and performance deficits, since their most-impacted areas of the brain are still in development.10,11,13,14 Without treatment, cognitive impairment grows worse, eventually developing into a lasting syndrome known as alcohol-related dementia—which represents about 10% of all dementia cases 1 (additionally, alcohol is estimated to contribute to roughly 29% of all other dementia cases 8 ).
Cognitive deficits are made worse by malnutrition, especially a deficiency of vitamin B (a common deficiency in alcohol dependent individuals). Malnutrition and heavy alcohol use can cause serious impairments in memory and language over time and can potentially result in a permanent cognitive disorder called Wernicke-Korsakoff syndrome, which causes amnesia and can lead to coma if left untreated.1,2,6,7
What happens after 6 months of no alcohol?
Timeline: What Happens When You Stop Drinking Alcohol? – If you’re ready to give up alcohol, and you are drinking every day, here is a timeline of what you can expect in regards to your mental and physical health when you stop drinking. If you have alcohol use disorder but only drink on weekends, know that you will also get benefits from stopping:
After One Day: The first day is always the hardest, but it’s also an important milestone. After 24 hours without alcohol, your body will start to detoxify and you may experience withdrawal symptoms. It’s important to remember that they are only temporary and will usually subside within a few days. For individuals with severe alcohol dependence, however, withdrawal symptoms can be more severe and may require medical attention. After Three Days: After three days, you will likely start to feel more like yourself. However, individuals who have been drinking heavily for long periods of time may still experience some symptoms of withdrawal and may even have hallucinations or delirium tremens (DTs) and seizures. Delirium tremens is a a serous and life threatening condition, and If you’re concerned about your symptoms, it’s important to talk to your doctor. After One Week: After one week without alcohol, your risk of seizures is much less. Also, your risk of developing cardiovascular disease will start to decrease. This is because alcohol can increase your blood pressure and make your heart work harder. In the coming weeks, your liver will also begin to repair itself. After One Month: A month alcohol-free is a big accomplishment. This is usually when people start to feel their best after giving up alcohol. By this point, most physical withdrawal symptoms should have subsided and you should start to feel less anxious and more positive. One study showed that after 6 weeks of abstinence from alcohol, brain volume increases by an average of 2%. After Six Months: After half a year without drinking, you will really start to reap the rewards. Your risk of developing cancer will decrease, and your liver function will have greatly improved. You’ll also have more energy and stamina, and you may notice that your skin looks healthier. After One Year: Congrats on making it to 12 months! At this point, your risk of developing all types of disease will be reduced and your bone density will start to increase. Keep in mind that everyone is different and will experience different things when they stop drinking.
While giving up alcohol can be a challenge, it’s important to remember that the benefits are well worth it.
How many brain cells do you lose after drinking alcohol?
We’ve all heard it, whether from parents, teachers, or after-school specials: alcohol kills brain cells. But is there any truth to this? Experts don’t think so. While drinking can certainly make you act and feel as though you’ve lost a brain cell or two, there’s no evidence that this actually happens.
What are the benefits of not drinking alcohol for 11 days?
Enjoy Improved Metabolism And Digestion – Alcohol products are full of sugar and empty calories. While two weeks is not a long amount of time, my patients often are already starting to eat healthier, see their metabolism improve, and experience some weight loss after quitting alcohol,
Their improvement in nutrition also starts to positively affect the body’s kidney function and vision abilities. Alcohol products can also be very acidic. After two weeks without drinking, the stomach lining can start to normalize, and acid burn can be reduced. This can cause you to regain your appetite and feel fewer symptoms of nausea and indigestion.
In general, you may start to experience physical benefits such as increased energy, reduced anxiety, and improved liver health. You might also notice positive changes in your personal life, such as improved relationships and more free time for hobbies.
