Does alcohol relax the nervous system?
How alcohol affects anxiety – Alcohol is a depressant. It slows down processes in your brain and central nervous system, and can initially make you feel less inhibited.10,11 In the short-term, you might feel more relaxed – but these effects wear off quickly.
How does alcohol affect the sympathetic nervous system?
Among its many physiological effects, alcohol robustly activates the sympathetic nervous system. Our laboratory has reported that simulated binge alcohol consumption increases muscle sympathetic nerve activity (MSNA) (5), a finding consistent with several other alcohol and microneurographic studies (6–12).
What nerves are damaged by alcohol?
Exams and Tests – The health care provider will perform a physical exam and ask about symptoms. An eye exam may show eye problems. Excessive alcohol use often makes the body unable to use or store certain vitamins and minerals. Blood tests will be ordered to check for a deficiency (lack) of:
Thiamine (vitamin B1) Pyridoxine (vitamin B6) Pantothenic acid and biotin Vitamin B12 Folic acid Niacin (vitamin B3) Vitamin A
Other tests may be ordered to rule out other possible causes of neuropathy. Tests may include:
Electrolyte levels Electromyography ( EMG ) to check the health of the muscles and the nerves that control the musclesLiver and kidney function tests Thyroid function tests Levels of vitamins and minerals in the body Nerve conduction tests to check how fast electrical signals move through a nerve Nerve biopsy to remove a small piece of a nerve for examination Upper GI and small bowel series Esophagogastroduodenoscopy ( EGD ) to examine the lining of the esophagus, stomach, and first part of the small intestine Voiding cystourethrogram, an x-ray study of the bladder and urethra
Can alcohol cause neurological damage?
Abstract This article reviews the different acute and chronic neurological manifestations of excessive alcohol consumption that affect the central or peripheral nervous system. Several mechanisms can be implicated depending on the disorder, ranging from nutritional factors, alcohol-related toxicity, metabolic changes and immune-mediated mechanisms.
Recognition and early treatment of these manifestations is essential given their association with high morbidity and significantly increased mortality. Keywords: Excessive alcohol consumption Neurological complications Hepatic encephalopathy Resumen En este artículo se revisan las distintas manifestaciones neurológicas del consumo excesivo de alcohol, que pueden ser agudas o crónicas y afectar al sistema nervioso central o periférico.
El mecanismo por el cual se producen varía de un grupo de trastornos a otro. Destacan factores nutricionales, efectos tóxicos del alcohol, factores metabólicos e incluso inmunológicos. Estas manifestaciones pueden conllevar una gran morbilidad y un aumento significativo de la mortalidad, por lo que es importante reconocerlas y tratarlas precozmente.
Palabras clave: Alcoholismo Complicaciones neurológicas Encefalopatía hepática Full Text Introduction Excessive or harmful alcohol consumption is defined as the consumption of 40–60 g/day of alcohol in women or 60–100 g/day in men. Although it does not meet the criteria for alcohol dependency, this level of consumption can produce clinical changes.
Alcohol use disorder appears when excessive alcohol consumption causes the deterioration of an individual’s social, work and family relationships.1 The World Health Organization’s report on excessive alcohol consumption identified more than 60 alcohol-related diseases.2 The systemic effects of alcohol include changes in the digestive tract and the liver, the heart and vascular system, the skeletal and muscular systems, nutritional status, the immune, endocrine and haematological systems, and in the central and peripheral nervous systems.
Several alcohol-related neurological complications have been described ( Table 1 ), and pathogenesis varies greatly among the different disorder groups, although one of the most frequent causes is nutritional deficiency. Alcohol can produce alcoholic liver disease that can be accompanied by a wide variety of neurological manifestations, including hepatic encephalopathy (HE).
In this article, we will examine the different neurological manifestations of excessive alcohol consumption, the neurological alterations most frequently found in alcoholic liver disease—such as HE—and the best diagnostic approach in clinical practice.
- Central nervous system involvement Acute complications Acute intoxication The symptoms of alcohol intoxication are the result of the inhibitory effect of alcohol on the nerve cells of the brain and spinal cord.
- Some of the immediate effects of acute alcohol ingestion—such as loquacity, loss of social inhibition, and aggressiveness—appear to be due to the inhibition of certain subcortical structures (perhaps the midbrain reticular formation) that modulate the activity of the cerebral cortex.3 However, as more alcohol is consumed, this inhibitory action extends to cortical and other brain stem and spinal neurons, and can cause decreased alertness and coma with respiratory failure.
Some susceptible individuals may experience amnesic lacunae and seizures after relatively mild alcohol intoxication.4 The severity of symptoms of acute alcohol intoxication are related to blood alcohol levels 5 ( Table 2 ). These levels should be taken merely as a guide, and will vary between individuals according to sex, habitual consumption, and genetic and metabolic factors.
Acute alcohol intoxication should be treated with supportive measures and monitoring of the individual’s level of consciousness. Alcoholic coma, with its associated respiratory depression, is a medical emergency that requires appropriate life support measures. Alcohol withdrawal syndrome Alcohol withdrawal syndrome, or abstinence syndrome, is the clinical manifestation of abruptly terminating or substantially reducing intake in patients who have developed tolerance and dependence.
Alcohol acts basically through 2 specific neuronal receptors. On the one hand, it regulates the neurotransmitter gamma-aminobutyric acid type A receptor that inhibits neuronal excitability, which explains its sedative and hypnotic effects. On the other hand, alcohol increases glutamate N-methyl- d -aspartate receptor expression, which in turn increases glutamate activity and causes hyperexcitation.
Chronic alcohol consumption induces neuroadaptive changes (tolerance), increases glutamate N-methyl- d -aspartate receptor expression, and desensitises the response and the expression of gamma-aminobutyric receptors.6 The manifestations of withdrawal syndrome (a wide range of severe symptoms, ranging from distal hand tremor, anxiety, insomnia and visual hallucinations to psychomotor agitation, autonomic hyperactivity, seizures or coma) appear to be mediated by an increase in excitatory neurotransmitters at the expense of inhibitory neurotransmitters.
Symptoms typically onset 6–24 h after interruption or reduction of alcohol consumption. The most serious form, which usually appears 72 h after withdrawal, is delirium tremens, characterised by disorientation, agitation and visual hallucinations, accompanied by autonomic signs such as hyperventilation, tachycardia and diaphoresis.
It can also be accompanied by metabolic and electrolyte alterations, such as hypomagnesaemia. The mortality rate is 5–15%, mainly due to metabolic, cardiovascular and infectious complications.7 According to the European Association for the Study of the Liver, the treatment of choice in patients with acute withdrawal syndrome and alcoholic liver disease is benzodiazepines, 8 since they reduce the risk of epileptic seizures.
Long-acting benzodiazepines, such as diazepam, are used, and the dose should be tapered over time. However, in elderly patients, in patients with hepatic failure, or when excessive sedation must be avoided, the lowest possible dose of short- or intermediate-acting benzodiazepines, such as lorazepam, is recommended.
In the case of hallucinations and agitation that do not respond to benzodiazepines, haloperidol may be added, although it should only be used in combination with benzodiazepines, because administration of antipsychotics alone may increase the risk of seizures. Other drugs, such as alpha-2 agonists (clonidine and dexmedetomidine) and beta-blockers, can be used as adjuvant treatments to control autonomic hyperactivity.
Studies in other drugs, such as carbamazepine, gabapentin and topiramate, have so far yielded promising results.9 Wernicke’s encephalopathy Wernicke’s encephalopathy (WE) and Korsakoff syndrome, which were originally described as separate entities, are now considered the acute and chronic stages, respectively, of Wernicke–Korsakoff syndrome.
The real prevalence of WE cannot be accurately estimated, although different studies have observed typical WE lesions in 0.2–2.8% of the autopsies performed in the general population compared with a prevalence of 12.5% in autopsies performed on alcoholics.10 WE is caused by a vitamin B1 (thiamine) deficiency, which plays a key role in carbohydrate metabolism as an essential coenzyme in the Krebs cycle and the pentose phosphate pathway (transketolase, α-ketoglutarate dehydrogenase, pyruvate dehydrogenase, etc.).
Since these enzymes regulate energy metabolism in the brain, thiamine deficiency can cause brain damage, mainly in regions with greater metabolic demand, such as the paraventricular region of the thalamus and hypothalamus, the mammillary bodies, the periaqueductal grey, the floor of the fourth ventricle, and the cerebellar vermis.
- Thiamine is found in both animal and plant foods.
- It is absorbed by the duodenum, and bodily reserves can be depleted in 2–3 weeks.
- In developed countries, more than 80% of cases of WE occur in the context of malnutrition associated with alcohol consumption.
- However, studies have shown that WE in alcoholics can involve mechanisms other than malnutrition, such as impaired gastrointestinal absorption of thiamine and a reduced capacity to store and metabolise the vitamin in the liver.11 Other clinical situations that lead to thiamine deficiency should also be borne in mind.
These generally involve poor intestinal absorption (gastrointestinal surgery, hyperemesis gravidarum) or an increase in body requirement (systemic diseases).12 From the clinical point of view, WE is characterised by the classic triad of oculomotor disturbance, ataxia and confusion, although the complete triad occurs only in 16% of patients.13 Ocular alterations are complex, and consist mainly of a combination of alterations such as, for example, horizontal or vertical nystagmus, unilateral or bilateral oculomotor paresis, or conjugate gaze palsy.
Ataxia mainly affects the trunk by altering gait and balance; limb ataxia and dysarthria are less common. Confusion or encephalopathic symptoms, meanwhile, develop within days or weeks and are characterised by profound disorientation, inability to concentrate, apathy, indifference, inattention, drowsiness and coma.
Other signs and symptoms are hypothermia resulting from posterior hypothalamic involvement, tachycardia or postural hypotension due to autonomic nervous system dysfunction, or polyneuropathy due to multiple vitamin deficiency.12 Diagnosis is mainly clinical.
Some additional tests can help confirm or rule out other suspicions, but should never delay the start of treatment. A thiamine blood test will show thiamine serum levels and transketolase enzyme activity in peripheral blood. This test, however, usually takes time and is of little practical use since normal ranges do not rule out a diagnosis of WE.
As far as brain imaging tests are concerned, the most useful complementary test for confirming diagnosis is magnetic resonance imaging (MRI). The most distinctive lesion is reversible cytotoxic oedema, visualised in T2, FLAIR and DWI sequences in the periventricular region and diencephalon ( Fig.1 ).
Furthermore, mammalian body atrophy, which is usually present in patients with chronic lesions, can start to be detected within the first week after onset of the disease.14 WE is a medical emergency because it is potentially reversible and delayed treatment or no treatment at all can cause serious sequelae and even death.
Treatment consists of urgent thiamine replacement. Thiamine therapy has been evaluated in a single randomised double-blind study in 107 patients, in which the efficacy of different intramuscular doses (5, 20, 50, 100 and 200 mg) of thiamine daily for 2 days was compared.
Response, defined as improved neuropsychological test score, was evaluated on the third day after treatment. The authors concluded that the 200 mg dose was superior to the other dosages.15 Although there is no clear consensus on the ideal thiamine dose, pharmacokinetic studies have shown the half-life of thiamine to be around 96 min, so 2 or 3 daily doses are considered appropriate.16 Given the higher incidence of adverse effects in intramuscular administration (high volume and painful administration), intravenous infusion of thiamine diluted in 100 ml of physiological saline or 5% dextrose over 30 min is recommended.
According to evidence from published series and the recommendations of the European Federation of Neurological Societies, the administration of between 100 and 200 mg of intravenous thiamine is considered adequate in non-alcoholic patients, while alcoholic patients require doses of up to 500 mg 3 times daily.10 Other recommendations are a speedy return to a normal diet and continuous treatment until clinical improvement is observed.
According to the literature, when untreated or insufficiently treated, WE-induced brain damage can lead to death in 20% of cases or to the chronic form of WE (Korsakoff syndrome) in 80% of cases.17 Chronic complications Korsakoff syndrome Korsakoff syndrome, which is mainly caused by malnutrition associated with chronic alcoholism, usually emerges in the aftermath of WE, although it can sometimes appear in patients with no history of WE, or with sub-acute, undiagnosed episodes.
However, it can also be a symptom of malnutrition due to other causes or a symptom of diseases involving ischaemic, neoplastic or other injury to the medial and inferomedial thalamic regions in the temporal lobes.18 From a clinical point of view, it is characterised by memory impairment that is out of proportion to other cognitive functions in an awake, attentive and responsive patient.
Important manifestations are learning deficits and memory loss, affecting both anterograde and retrograde events. Recent memory is usually more affected than remote memory, and the creation of false memories, or confabulation, in speech that can even be induced by questions about the patient’s recent activities is characteristic of this syndrome.
Other cognitive functions, such as concentration, spatial organisation, visual or verbal abstraction, may also be affected, and patients are usually apathetic and lacking in initiative, spontaneity and self-criticism.19 Korsakoff syndrome is often thought to be untreatable; however, after thiamine administration, only 25% show no recovery, 25% experience discrete improvement, 25% significant improvement, and in 25% memory is completely recovered.20 Marchiafava–Bignami disease Marchiafava–Bignami disease was first described in 1903 in Italian alcoholic wine drinkers, and since then it has been observed in other nationalities in association with abuse of any alcoholic beverage.
- It affects chronic alcoholics almost exclusively, although cases have occasionally been described in non-alcoholics with malnutrition.21 It is a rare entity that is characterised by progressive demyelination and necrosis of the central part of the corpus callosum.
- On brain imaging studies, it manifests as a well defined area of demyelination in the body of the corpus callosum, which can then extend to various regions of the subcortical white matter.
The aetiology is unknown and widely debated, with some experts suggesting the existence of a toxic factor, not yet identified, which is present in some alcoholic beverages as the culprit. However, given the low prevalence of this entity in alcoholics, and the fact that it has also been described in some non-alcoholics, it probably has an unidentified nutritional, metabolic or enzymatic aetiology.22 The clinical characteristics of this disease vary, and there is no well-defined clinical syndrome.
- Most patients present progressive dementia, usually subacute at onset, with predominance of apractic or aphasic disorders, oppositional hypertonia, dysarthria, frontal release reflexes and, sometimes, hemiparesis or signs of interhemispheric disconnection.
- Some patients also present decreased alertness and seizures.
The clinical course is variable; some patients will become comatose and die, others can survive several years with dementia, while in others partial recovery is possible.23 The diagnosis is difficult because of the wide spectrum of symptoms. Diagnosis was hitherto based on post-mortem studies, but today a history of alcoholism together with clinical manifestation and, above all, brain imaging studies, specifically MRI, are essential to confirm diagnosis.
Typical lesions seen on MRI are demyelination, swelling and necrosis of the corpus callosum, with varying degrees of subcortical white matter involvement.24 Given its uncertain aetiology, there is no specific treatment for Marchiafava–Bignami disease, although abstinence and vitamin supplements are recommended.
Good response to high doses of corticosteroids has also been reported in some studies.25 Alcohol-related dementia The term alcohol-related dementia is used to describe a form of dementia attributable to the direct effects of chronic alcohol consumption on the brain.
Studies have shown that consumption of 140 g or more of alcohol per day for a prolonged period of time can produce moderate cognitive alterations.26 However, alcohol-related dementia has never been accurately defined from a clinical or pathological perspective, and the diagnosis of this entity has sparked considerable controversy in recent years.
Furthermore, the interaction between nutritional deficiencies, consumption of other substances, psychiatric comorbidity and repeated head injuries in chronic alcoholic patients raise doubts about the existence of alcohol-related dementia per se. Some authors, therefore, prefer to use the term “alcohol-related brain damage” to describe both the aetiology and symptoms of the widely differing alcohol-related cognitive disorders presented in these patients.
Neuronal damage or depletion, from a physiopathological perspective, is believed to be related to glutamate neurotoxicity, oxidative stress and diminished neurogenesis, triggered by chronic alcohol abuse.27 Post-mortem anatomopathological studies of patients diagnosed with alcohol-related dementia often show nonspecific findings, such as predominantly frontal cerebral atrophy, typical Wernicke–Korsakoff syndrome lesions, communicating hydrocephalus, Alzheimer’s disease, or traumatic injuries of variable severity.28 From a clinical point of view, it is characterised by an insidious onset with stepwise progression of symptoms that overlap with other neurodegenerative dementias.
In the early stages, neuropsychological studies usually reveal frontal-subcortical cognitive impairment, with slowing of mental processes, attention deficit, changes in immediate or short-term memory, decline in visual spatial skills, and decline in executive functions, such as planning and organisation.29 Alcohol-related cerebellar degeneration Alcohol-related cerebellar degeneration is a common complication that affects up to 25% of alcoholics, and is one of the most frequent causes of acquired ataxia in adults.30 The pathogenesis of this entity is complex and not entirely clear, although a synergistic mechanism involving both the toxic effect of alcohol and the consequences of vitamin B1 deficiency may be involved.
Recent studies have shown the presence of anti-tissue transglutaminase 2 antibodies in chronic alcoholics, which raises the possibility of alcohol-induced hypersensitivity to gluten.31 According to the hypothesis put forward by some authors to explain this phenomenon, increased gut permeability caused by alcohol-induced intestinal mucosa lesions found in alcoholic patients could increase exposure of the immune system to pathogenic antigens (including gliadin peptides).
Then, blood–brain barrier impairment induced by chronic alcohol consumption would, by as yet unknown mechanisms, allow the passage of these antibodies to the brain, thus causing cerebellar degeneration similar to gluten-induced cerebellar ataxia.32 In fact, one study has shown a higher prevalence of anti-gliadin antibodies in patients with alcohol-induced cerebellar degeneration compared to the general population (44% vs 12%).33 From a clinical perspective, cerebellar degeneration is characterised by trunk ataxia with wide-based gait, instability and variable degrees of lower limb dysmetria.
Dysmetria in the upper limbs, dysarthria or oculomotor disturbance are less common. In most cases, cerebellar degeneration evolves over a period of several weeks or months and persists for years. Both anatomopathological and neuroimaging studies show degeneration of all the neurocellular elements of the cerebellar cortex, and particularly Purkinje cells in the anterior and superior surface of the vermis.34 Cerebellar atrophy is easily observed on CT and brain MRI scans ( Fig.2 ).
No specific treatment has been defined, although administration of vitamin supplements and abstinence from alcohol are recommended. Peripheral nervous system involvement Acute compressive neuropathy Excessive alcohol consumption is traditionally associated with ‘Saturday night palsy’, caused by compression of the radial nerve against the humerus for several hours.
- It usually occurs when the individual falls asleep with their arm hanging over the armrest of a chair, or being compressed by the weight of the body.
- Clinically, it is characterised by an inability to perform dorsiflexion of the wrist and extension of the fingers.
- Neurophysiological studies using electromyography is useful both for diagnosis and prognosis, although the condition is self-limiting and most patients recover within 3–6 months.35 Chronic alcoholic polyneuropathy Chronic polyneuropathy is the most common complication in alcoholic patients.36 Recently, strong evidence has come to light to show alcoholic polyneuropathy to be the result of a multifactorial process primarily mediated by the toxic effect of alcohol and modulated by other factors, such as genetic predisposition, thiamine deficiency, malnutrition and other systemic diseases.37 This is a predominantly axonal, sensorimotor polyneuropathy with distal, symmetric features.
The onset of symptoms is insidious and symmetric, predominantly sensory, in the form of dysesthesia, burning sensation and burning pain on the soles of the feet that later develops into cramp in the calves and the hands. Motor symptoms usually manifest later, and are characterised by muscle weakness and atrophy, especially in the distal muscles of the upper or lower limbs.
- Vegetative vascular and skin defects (sweaty, atrophic, glossy, almost hairless skin) with associated dysautonomia are also typical.
- The treatment consists of a balanced diet with vitamin supplements, rehabilitation and alcohol abstinence.
- However, recovery is slow and often incomplete.
- Patients presenting with neuropathic pain can be treated with drugs such as gabapentin or amitriptyline.
Disulfiram neuropathy Disulfiram, a drug used to facilitate alcohol abstinence, has very occasionally been associated with peripheral neuropathy. The physiopathological mechanism behind this is unknown, but it manifests as an axonal sensorimotor, dose-dependent polyneuropathy that onsets a few weeks or months after the start of disulfiram treatment.
- Clinically, it is characterised by distal paresthesias in a stocking-glove distribution together with predominantly distal muscle weakness and distal areflexia.
- Prognosis will depend on severity and the degree of axonal loss, although it is usually reversible after suspension of disulfiram therapy.38 Muscle involvement Acute or chronic alcoholic myopathy Alcohol can damage skeletal muscles by altering calcium channels or the integrity of the muscle fibre membrane or sarcolemma.
Clinically, alcoholic myopathy can be characterised by acute myalgia, rhabdomyolysis and elevated creatine kinase (CK). In severe cases, it can lead to acute kidney failure and myoglobinuria. The chronic form presents as muscle atrophy, usually proximal, which frequently coexists with neuroperipheral alterations, such as chronic alcoholic polyneuropathy.
Diagnosis is performed with neurophysiological tests (electromyography) and histopathological study of muscle biopsy. In some cases, skeletal myopathy is accompanied by dilated cardiomyopathy. Treatment is based on alcohol abstinence, physiotherapy and a balanced diet. Prognosis is cautious, since some patients experience an improvement in clinical weakness, but others do not recover muscle strength or mass.39 Hepatic encephalopathy Hepatic encephalopathy (HE) is a common, serious complication of liver cirrhosis and an indicator of poor prognosis in these patients.
It is a complex syndrome involving neurological and psychiatric manifestations, and occurs in patients with advanced liver disease and portosystemic shunting.40 Symptoms fluctuate over time and vary greatly, ranging from tremor and dysarthria to hepatic coma, and include (a) altered level of consciousness that can progress from mild confusion to coma; (b) neuropsychiatric symptoms, such as behavioural changes, mental slowness, reversal of the sleep–wake cycle, or psychomotor agitation, and (c) neuromuscular symptoms, such as flapping.
The West Haven criteria stratifies HE into 4 grades, from mild to most severe ( Table 3 ). Because the clinical manifestations of HE are non-specific and can be observed in other diseases or metabolic disorders, diagnosis is made on the basis of complementary tests that can reasonably exclude other potential causes.
Diagnosis of WE in patients with chronic alcoholism is challenging, since the differential diagnosis is extensive. Clinically, the diagnosis of WE can be difficult because, as explained previously, the classic triad is often absent. The presence of alterations in ocular motility, nystagmus and ataxia should raise suspicion of WE, while the presence of flapping or pyramidal syndrome is suggestive of HE.
Clinical findings suggestive of alcohol withdrawal are anxiety, tachycardia, visual hallucinations and postural tremor. Differential diagnosis between HE and Marchiafava–Bignami disease does not generally present any difficulty, since the latter is clinically characterised by the presence of dementia and spasticity.
Brain neuroimaging using computed tomography (CT) or MRI makes it possible to rule out structural alterations, such as space-occupying lesions, subdural haematomas or ischaemic/haemorrhagic strokes, which can be suspected when neurological focal signs are observed in the examination.
These imaging studies can also rule out viral or autoimmune encephalitis that can clinically overlap HE. A typical MRI finding in HE is hyperintense basal ganglia on T1-weighted images, especially in the globus pallidus. This is related to manganese deposits caused by portosystemic shunts, and could explain the existence of parkinsonian signs in these patients.41 An electroencephalogram, a neurophysiological test that shows the electrical activity of the brain, can rule out a non-convulsive status epilepticus or findings typical of a post-critical state.
However, HE produces alterations in brain activity that are shown on the electroencephalogram as slow frequency, high amplitude waves and three-phase waves—findings that can also be found in other metabolic comas.42 Finally, the study of cerebrospinal fluid will rule out meningitis or bacterial or viral meningoencephalitis, which should be suspected when fever and meningeal signs are present.
- Conclusions Chronic alcohol consumption can produce numerous neurological manifestations.
- The most common are polyneuropathy, cerebellar degeneration and dementia, and the most serious are WE, Korsakoff syndrome and Marchiafava–Bignami disease.
- All these are associated with significant morbidity and mortality, and therefore must be correctly diagnosed and treated in order to avoid irreversible complications.
They are caused by vitamin deficiencies, the direct toxic effects of alcohol, immune alterations and unknown mechanisms, among others. In addition, the differential diagnosis of HE can be difficult due to its similarity with alcohol-related neurological disorders.

How do you calm your nervous system after drinking?
Ways to manage and reduce hangxiety – Unfortunately, there’s no hangxiety cure, but one of the best ways to manage and reduce hangxiety is to choose alcohol-free alternatives to your favorite drinks. At Lyre’s, our looks, tastes and sashays around the palate just like the original, so you can enjoy your favorite drink without worrying about hangxiety the following day.
Eat before drinking and never drink on an empty stomach Drink plenty of water and stay well hydrated while you’re drinking – a 1:1 ratio should be maintained (1 alcohol drink per hour and 1 water per alcoholic drink) Set a limit and stick to it (i.e. two standard drinks maximum)
To manage hangxiety while you’re experiencing it, try:
Rehydrate: drink lots of water and nutrient enhancing drinks Eat a light meal: eat a meal that’s easy to digest and avoid greasy, processed foods Get some rest: If you’re able to, get some sleep and give yourself a chance to relax Take some over-the-counter pain medication: This may help with physical symptoms Practice mindfulness: Meditation and slow-breathing exercises can help overcome symptoms of anxiety Go easy on yourself: Don’t be too hard on yourself and avoid overthinking your actions (you probably weren’t the only one drinking) Talk yourself through your worries: If you have trusted friends and family, it might help to talk to them too Try stress-relieving activities: activities like taking a bath, drawing, yoga, walking, and listening to calming music or meditation can help relieve your hangxiety.
In short, hangxiety is common; while not everyone will experience the same symptoms or severity every time, you’re not alone in your concerns, worries, and emotions. If you’re experiencing severe hangxiety, there’s a growing range of fantastic you can try to enjoy a night out without the hangover! : Hangxiety and how to reduce it
Why does alcohol calm my brain?
Does Alcohol Really Help You Relax? Does drinking do what we think it does? Source: Irene Kredenets/Upsplash Announcing you need a drink when feeling stressed or worn out is usually met with enthusiastic agreement. Many of us take for granted that drinking eases and helps us relax in social settings or at the end of a hard day.
Especially in 2020, alcohol sometimes feels like a necessary vehicle for coping with an uncertain, and often scary world. But lately, it seems like our entire society might be developing a bit of a drinking problem. When “Rosé All Day” is printed on fitness wear, and so-called “Wine Moms” are said to have influenced the recent presidential election, it’s worth looking at whether drinking is doing what we think it does.
Does alcohol really “take the edge off” of our days, or does it just make things worse? According to a recent study released by the RAND corporation and supported by the National Institute of and Alcoholism (NIAAA), drinking has soared during the pandemic.
Heavy drinking for women has increased by 41 percent. “The magnitude of these increases is striking,” Michael Pollard, lead author of the study and a sociologist at RAND, “People’s increases, anxiety increases, alcohol use is often a way to cope with these feelings. But depression and anxiety are also the outcomes of drinking; it’s this feedback loop where it just exacerbates the problem that it’s trying to address.” If you are truly drinking moderately, which the defines as one 5 oz glass of wine or 12 oz beer for women and two for men, and alcohol doesn’t have a noticeable effect on your overall mood or sleep, you are probably staying clear of alcohol’s anxiety-elevating effects.
But if you are more than a “one and done” drinker, or are worried that alcohol is affecting your well-being and health, it’s worth looking at how it is affecting you. Alcohol and the Brain Alcohol has a “biphasic,” or two-phase, effect on the brain. It both increases levels (leading to feelings of euphoria) and inhibits excitatory neurotransmitters, which slows down your brain functioning.
- The slowing down of the excitatory neurotransmitter is how alcohol acts as a depressant.
- Once dopamine levels go back to normal, we’re still left with a depressed system, which often leads to another drink to get the dopamine levels back up.
- The more we drink the less effect alcohol has on our dopamine receptors, but by then our brain has learned to crave alcohol when we’re stressed.
This interference with our neurotransmitters can increase anxiety, often for the entire day after drinking. This can lead to wanting a drink the next evening to wind down, causing the entire cycle to start over again. Very often out alcohol can lead to a significant decrease in your overall anxiety.
Alcohol and Your Sleep While the sedative effect of alcohol initially might help us fall asleep, as little as one drink too close to bedtime can wreak havoc on both the quality and quantity of your sleep. Alcohol interferes with our sleep stages, especially sleep, the restorative part of our, When alcohol finally leaves your bloodstream, you’re often jolted awake as your, coming off of several hours in a depressed state, tries to achieve homeostasis by lurching into active mode.
Sleep is the ultimate self-care activity. The importance of quality sleep in all mental health issues, and overall well-being, cannot be overstated. It is the first line of defense against chronic anxiety and depression. Researcher Matthew Walker, the author of the excellent book, says it perfectly, “The best bridge between despair and hope is a good night’s sleep.” Midnight ruminating, 3 am wake-ups, night sweats, morning headaches, and brain fog, are all signs that alcohol is impacting your sleep, and bringing along the anxiety you are trying to avoid. Do You Have a Problem? We often have a binary way of thinking about alcohol use – either you’re an alcoholic and your drinking is truly out of control, or there’s no problem at all. But that isn’t an accurate picture. Most people who drink too much are not addicted and wouldn’t experience what we typically think of as withdrawal if they stopped.
They don’t need treatment or intervention. In fact, it’s likely no one around them is worried about their drinking at all. But from a mental health perspective, alcohol is still affecting them negatively. A friend recently shared that her husband expressed concern that her drinking had increased rapidly over the course of quarantining.
She told him, “I know I’ve been drinking too much. This is what I do instead of taking an,” Imagine your doctor suggesting you take a that will help with anxiety for about 30 minutes, then will make your anxiety worse. It is also highly addictive. It causes sleep problems, depression, headaches, stomach issues,, and birth defects.
Further, it markedly increases your susceptibility to many types of cancer, is associated with reckless behavior and blackouts, and is responsible for more than in America each year. Hopefully, you would find a new doctor. Alcohol as medication is a terrible idea. If your drinking is medicinal, it’s time to look for safer, more effective ways to cope.
Here are some steps to take if you’d like to shift your alcohol use. Get real about how much you’re actually drinking. Bringing to our habits is always the first step in changing them. Next time you’re drinking, use a measuring cup to pour out 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of spirits.
- That’s one drink.
- Do this with every drink you have in order to keep yourself honest.
- In a notebook, keep track of how many drinks you have each day, and rate your overall anxiety, depression, and sleep quality.
- Find other ways to relax.
- The ritual of signifying the end of the day by sitting down with a drink is hard to give up unless we have an enticing alternative.
Identify when you will most want a drink, and think about what you could do instead. Swapping in a non-alcoholic drink that you reserve for happy hour can often stand-in effectively for alcohol. Reading a book, taking a bath, connecting with a loved one, or even just going to bed early are all proven anxiety relievers.
- Take a break.
- Dryuary is right around the corner, and there are countless free or low-cost programs on-line to offer support and guidance to anyone wanting to take an alcohol time-out.
- Not drinking at all, for at least a month, is the best way to see how alcohol is affecting your life, and to decide whether it’s worth it.
Be aware that the more you’re drinking now, the longer it will take your body to truly reset and for you to feel the full impact of going without. A good rule of thumb is one month for every daily drink. If that feels intimidating, start smaller and see if you can add on as you move ahead.
Ideally, keep the time-line open. The idea of a drinking break is to diminish drinking’s importance in your life. If you are counting the days until you can drink again, it will have the opposite effect. If you decide to re-introduce drinking after this period, keep in mind that all habits grow. In the same way that we might grow an exercise habit by starting with 15 minutes a day, one daily drink can easily become three without our noticing.
Drinking mindfully for the long term will likely require a lot of attention and periodic re-assessment. None of the above suggestions replace treatment or a twelve-step program. If you experience strong resistance to any of the above steps, it’s worth getting curious about the role of alcohol in your life, and whether this is how you want to live.
- While certain people are natural moderators who never drink more than the suggested amount, the truth is, most people who drink consistently will eventually need to re-evaluate the way they are drinking.
- There shouldn’t be or stigma about wanting to slow down or stop drinking because needing to do so isn’t the exception; it’s the rule.

Does alcohol damage vagus nerve?
Alcohol, the vagus nerve and multi-organ inflammation – John Littleton The tenth cranial nerve, the vagus, is distributed throughout the body, including major divisions to all parts of the gut, and to the liver. This cholinergic nerve restrains inflammation, in all the organs to which the vagus is distributed, by the tonic release of acetylcholine (ACh) onto nicotinic receptors (nicAChRs) of the alpha7- subtype.
In addition to their presence on inflammatory cells, alpha7-nicAChRs are also present on cell bodies of the vagus in the CNS, where they cause vagal activation and neuroprotection. Since the presence of alcohol inhibits alpha7-nicAChRs, and a known chronic effect is to cause vagal neuropathy, these anti-inflammatory effects of the vagus are seriously compromised during alcohol exposure.
The primary hypothesis is that this reduced vagal function contributes to the chronic inflammation following oxidative stress, which is a common feature of alcohol-induced damage in many organs. If correct, this predicts that compounds with alpha7- nicAChR agonist properties will protect against alcohol-induced tissue damage, particularly if these compounds are also anti-oxidants.
The first specific aim of this proposal is to test the primary hypothesis in vitro by studying the interactions of alcohol and alpha7-nicAChR ligands on endotoxin-induced release of mediators from inflammatory cells (splenic, lung and peritoneal macrophages) from wild-type, and alpha7-nicAChR knock-out, C57Bl/6J mice.
The second specific aim is to test the hypothesis in vivo by exposing C57Bl/6J mice (wild-type, vagotomized, and alpha7-nicAChR knockouts) chronically to alcohol by forced consumption, and then evaluating endotoxin-induced release of inflammatory mediators in vivo.
- As part of these studies we will evaluate the therapeutic potential of the alpha7-nicAChR agonist, choline, and a methylquercetagetin which acts as a partial agonist at alpha7-nicAChRs.
- The latter was recently discovered by screening a native plant extract library, and has potent anti-oxidant activity in addition to its action at nicAChRs, where it has an affinity comparable to choline.
The ability of these compounds to inhibit endotoxin-induced release of inflammatory mediators following alcohol exposure will be studied in vitro and in vivo using the same methods as above. This project therefore tests a novel hypothesis for alcohol-induced organ damage based on the interaction between brain, gut and liver as represented by the vagus nerve, and tests a novel therapeutic approach to this.
What is considered heavy alcohol use?
Frequently Asked Questions Ethyl alcohol, or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches. Alcohol affects every organ in the body. It is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine into the bloodstream.
- Alcohol is metabolized in the liver by enzymes.
- However, the liver can only metabolize a small amount of alcohol at a time, leaving the excess alcohol to circulate throughout the body.
- The intensity of the effect of alcohol on the body is directly related to the amount consumed.
- A standard drink is equal to 14.0 grams (0.6 ounces) of pure alcohol.
Generally, this amount of pure alcohol is found in
- 12 ounces of beer (5% alcohol content).
- 8 ounces of malt liquor (7% alcohol content).
- 5 ounces of wine (12% alcohol content).
- 1.5 ounces or a “shot” of 80-proof (40% alcohol content) distilled spirits or liquor (e.g., gin, rum, vodka, whiskey).
No. One 12-ounce beer has about the same amount of alcohol as one 5-ounce glass of wine or 1.5-ounce shot of liquor. It is the amount of alcohol consumed that affects a person most, not the type of alcoholic drink. According to the, 1 adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to 2 drinks or less in a day for men and 1 drink or less in a day for women, when alcohol is consumed.
Drinking less is better for health than drinking more. Binge drinking is defined as a pattern of alcohol consumption that brings the blood alcohol concentration (BAC) level to 0.08% or more. This pattern of drinking usually corresponds to 5 or more drinks on a single occasion for men or 4 or more drinks on a single occasion for women.2 “Getting drunk” or intoxicated is the result of consuming excessive amounts of alcohol.
Binge drinking typically results in acute intoxication.2 Alcohol intoxication can be harmful for a variety of reasons, including:
- Impaired brain function resulting in poor judgment, reduced reaction time, loss of balance and motor skills, or slurred speech.
- Dilation of blood vessels, causing a feeling of warmth but resulting in rapid loss of body heat.
- Increased risk of certain, stroke, and liver diseases (e.g., cirrhosis), particularly when excessive amounts of alcohol are consumed over extended periods of time.
- Increased risk of, violence, and other injuries.
For men, heavy drinking is typically defined as consuming 15 drinks or more per week. For women, heavy drinking is typically defined as consuming 8 drinks or more per week. Excessive drinking both in the form of heavy drinking or binge drinking, is associated with numerous health problems, including
- Chronic diseases such as liver cirrhosis (damage to liver cells); pancreatitis (inflammation of the pancreas); various, including liver, mouth, throat, larynx (the voice box), and esophagus; high blood pressure; and psychological disorders.
- Unintentional injuries, such as, falls, drowning, burns, and firearm injuries.
- Violence, such as child maltreatment, homicide, and suicide.
- Harm to a developing fetus if a woman drinks while pregnant, such as,
- Sudden infant death syndrome (SIDS).
- Alcohol use disorders.3
There is a strong scientific evidence that drinking alcohol increases the risk for, including cancers of the mouth and throat, liver, breast (in women) and colon and rectum, and for some types of cancer, the risk increases even at low levels of alcohol consumption (less than 1 drink in a day).
- The evidence indicates that the more alcohol a person drinks, the higher his or her risk of developing an alcohol-associated cancer.
- The risk varies by many factors, such as the quantity of alcohol consumed and type of cancer.
- The recommends that adults who choose to drink do so in moderation – 1 drink or less on a day for women or 2 drinks or less on a day for men.
However, emerging evidence suggests that even drinking within the recommended limits may increase the overall risk of death from various causes, such as from several types of cancer and some forms of cardiovascular disease.1 According to the 2020–2025 1 some people should not drink alcoholic beverages at all, including:
- If they are pregnant or might be pregnant.
- If they are under the legal age for drinking.
- If they have certain medical conditions or are taking certain medications that can interact with alcohol.
- If they are recovering from an alcohol use disorder or if they are unable to control the amount they drink.
To reduce the risk of alcohol-related harms, the Guidelines recommend that adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to 2 drinks or less in a day for men or 1 drink or less in a day for women, on days when alcohol is consumed.
The Guidelines also do not recommend that individuals who do not drink alcohol start drinking for any reason and that if adults of legal drinking age choose to drink alcoholic beverages, drinking less is better for health than drinking more.1 By following the Dietary Guidelines, you can reduce the risk of harm to yourself or others.
Studies have shown that alcohol use by adolescents and young adults increases the risk of both fatal and nonfatal injuries. Research has also shown that people who use alcohol before age 15 are six times more likely to become alcohol dependent than adults who begin drinking at age 21.
- Other consequences of youth alcohol use include increased risky sexual behaviors, poor school performance, and increased risk of suicide and homicide.4,
- There is no known safe level of alcohol use during pregnancy.
- Women who are pregnant or plan on becoming pregnant should refrain from drinking alcohol.
Several conditions, including, have been linked to alcohol use during pregnancy. Women of childbearing age should also avoid to reduce the risk of unintended pregnancy and potential exposure of a developing fetus to alcohol.5, Generally, moderate consumption of alcoholic beverages by a woman who is lactating (up to 1 standard drink in a day) is not known to be harmful to the infant, especially if the woman waits at least 2 hours after a single drink before nursing or expressing breast milk.
- Legal limits are measured using either a blood alcohol test or a breathalyzer.
- Legal limits are typically defined by state law, and may vary according to individual characteristics, such as age and occupation.
All states in the United States have adopted 0.08% (80 mg/dL) as the legal limit for operating a motor vehicle for drivers aged 21 years or older (except for Utah, which adopted a 0.05% legal limit in 2018). However, drivers younger than 21 are not allowed to operate a motor vehicle with any level of alcohol in their system.
- Inability to limit drinking.
- Continuing to drink despite personal or professional problems.
- Needing to drink more to get the same effect.
- Wanting a drink so badly you can’t think of anything else.
Drinking is a problem if it causes trouble in your relationships, in school, in social activities, or in how you think and feel. If you are concerned that either you or someone in your family might have a drinking problem, consult your personal health care provider.

How do you know if you have nerve damage from alcohol?
Stroke – A stroke happens where there is a loss of blood flow to the brain.17 Research has shown that moderate amounts of alcohol (i.e., 7 to 14 drinks per week for females and 7 to 21 for males) and/or high amounts (i.e., 14 or more for females and more than 21 for males) have been associated with an increased risk of stroke.18 Additionally, heavy alcohol use can lead to complications that increase stroke risk, such as: cardiac disease (e.g., arrhythmias and cardiomyopathy), high blood pressure, platelet dysfunction, synthetic liver dysfunction, accelerated atherosclerosis (i.e., artery disease), acceleration of clotting cascade, direct cerebral vasoconstriction, hemo-concentration (i.e., an abnormally high concentration of blood), and hyperhomocysteinemia (i.e., high levels of homocysteine in the blood) due to folate deficiency.11 Common signs and symptoms of stroke include the sudden onset of the following: 19
Numbness or weakness in the face, arm, or leg, especially on one side of the body. Confusion, trouble speaking, and/or difficulty understanding speech. Vision problems in one or both eyes. Difficulties walking, dizziness, loss of balance, and/or lack of coordination. Severe headache without another known cause.
If someone is displaying any of the above symptoms, it’s important to call 911 right away.19 Depending on the type, stroke may be treated with medication to restore blood flow, surgical procedures, and other interventions, including rehabilitation.20
What does alcoholic nerve damage feel like?
Alcoholic neuropathy has many of the same symptoms as peripheral neuropathy. For most, this includes a tingling, burning, or painful feeling in their legs, feet, arms, and hands. They may not feel strong sensations in these areas, either, due to the damage to the nerves.
Which organ is most damaged by alcohol?
Drinking too much – on a single occasion or over time – can take a serious toll on your health. Here’s how alcohol can affect your body: Brain: Alcohol interferes with the brain’s communication pathways, and can affect the way the brain looks and works.
Cardiomyopathy – Stretching and drooping of heart muscle Arrhythmias – Irregular heart beat Stroke High blood pressure
Liver: Heavy drinking takes a toll on the liver, and can lead to a variety of problems and liver inflammations including:
Steatosis, or fatty liver Alcoholic hepatitis Fibrosis Cirrhosis
Pancreas: Alcohol causes the pancreas to produce toxic substances that can eventually lead to pancreatitis, a dangerous inflammation and swelling of the blood vessels in the pancreas that prevents proper digestion. Cancer: According to the National Cancer Institute: “There is a strong scientific consensus that alcohol drinking can cause several types of cancer.
- In its Report on Carcinogens, the National Toxicology Program of the US Department of Health and Human Services lists consumption of alcoholic beverages as a known human carcinogen.
- The evidence indicates that the more alcohol a person drinks–particularly the more alcohol a person drinks regularly over time–the higher his or her risk of developing an alcohol-associated cancer.
Even those who have no more than one drink per day and people who binge drink (those who consume 4 or more drinks for women and 5 or more drinks for men in one sitting) have a modestly increased risk of some cancers. Based on data from 2009, an estimated 3.5% of cancer deaths in the United States (about 19,500 deaths were alcohol related.” Clear patterns have emerged between alcohol consumption and increased risks of certain types of cancer:
Head and neck cancer, including oral cavity, pharynx, and larynx cancers.
Esophageal cancer, particularly esophageal squamous cell carcinoma. In addition, people who inherit a deficiency in an enzyme that metabolizes alcohol have been found to have substantially increased risks of esophageal squamous cell carcinoma if they consume alcohol.
Liver cancer.
Breast cancer: Studies have consistently found an increased risk of breast cancer in women with increasing alcohol intake. Women who consume about 1 drink per day have a 5 to 9 percent higher chance of developing breast cancer than women who do not drink at all.
Colorectal cancer.
For more information about alcohol and cancer, please visit the National Cancer Institute’s webpage ” Alcohol and Cancer Risk ” (last accessed October 21, 2021). Immune System: Drinking too much can weaken your immune system, making your body a much easier target for disease.
Is neurological damage from alcohol reversible?
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.
Can alcohol cause nervous system degeneration?
Alcoholic neuropathy – Alcoholic neuropathy occurs when too much alcohol damages the peripheral nerves. This can be permanent, as alcohol can cause changes to the nerves themselves. Deficiencies in B6 and B12, thiamine, folate, niacin, and vitamin E can make it worse. These vitamins are all needed for proper nerve function. Symptoms can include:
numbness, tingling, and prickly sensations in the arms and legsmuscle spasms and crampsmuscle weaknessmovement disordersurinary and bowel problems like incontinence, constipation, and diarrhea sexual dysfunction, such as impotence difficulty swallowing impaired speech dizziness vomiting and nausea
Why do my legs go numb when I drink alcohol?
Answer: – I believe your doctor is right. Alcohol has a direct toxic effect on the nerve fibers in the legs and arms. Alcohol can cause the degeneration of the myelin insulation of the nerve fiber as the nerve dies back from the feet and hands toward the upper leg and arm.
- Also, painful feet and weakness of the thigh muscle are part of the progression of this alcoholic polyneuropathy.
- Alcohol is the cause—no alcohol is the treatment.

- In people with alcoholic neuropathy, the peripheral nerves have been damaged by too much alcohol use.
- The peripheral nerves transmit signals between the body, the spinal cord, and the brain.
- Thiamine, folate, niacin, vitamins B6 and B12, and vitamin E are all needed for proper nerve function.
- Drinking too much can alter levels of these nutrients and affect the spread of alcoholic neuropathy.
Fortunately, abstaining from alcohol can help restore your nutritional health. This may improve your symptoms and help prevent further nerve damage. However, some alcohol-induced nerve damage is permanent.9 Celebrity Alcoholics You May Not Know About
What are 6 effects of alcohol on the brain?
ALCOHOL’S DAMAGING EFFECTS ON THE BRAIN Difficulty walking, blurred vision, slurred speech, slowed reaction times, impaired memory: Clearly, alcohol affects the brain. Some of these impairments are detectable after only one or two drinks and quickly resolve when drinking stops.
On the other hand, a person who drinks heavily over a long period of time may have brain deficits that persist well after he or she achieves sobriety. Exactly how alcohol affects the brain and the likelihood of reversing the impact of heavy drinking on the brain remain hot topics in alcohol research today.
We do know that heavy drinking may have extensive and far–reaching effects on the brain, ranging from simple “slips” in memory to permanent and debilitating conditions that require lifetime custodial care. And even moderate drinking leads to short–term impairment, as shown by extensive research on the impact of drinking on driving.
how much and how often a person drinks; the age at which he or she first began drinking, and how long he or she has been drinking; the person’s age, level of education, gender, genetic background, and family history of alcoholism; whether he or she is at risk as a result of prenatal alcohol exposure; and his or her general health status.
This Alcohol Alert reviews some common disorders associated with alcohol–related brain damage and the people at greatest risk for impairment. It looks at traditional as well as emerging therapies for the treatment and prevention of alcohol–related disorders and includes a brief look at the high–tech tools that are helping scientists to better understand the effects of alcohol on the brain.
