How alcohol affects the brain. The dangerous effect of alcohol on the human brain and its irreversible consequences

Contents of the article: classList.toggle()">toggle

Alcoholic drinks contain ethanol, which is the most “universal” poison; its effects are harmful to the entire body. And if organ damage remains invisible for the time being, the effect of alcohol on the brain becomes obvious after the first drink.

But these are only external signs - a change in behavior when a person becomes strange, funny or aggressive. Much more dramatic is how alcohol affects the human brain, and as a rule, this leads to serious consequences.

The effect of alcohol on the human brain

What happens to the brain when drinking alcohol? Everyone knows that using alcohol you can easily remove a grease stain. But the brain is 70% fat (lipids), and only 30% protein. The alcohol contained in alcoholic drinks is absorbed into the blood unchanged, enters the brain tissue and, having done its dirty work, breaks down into toxic substances.

Lipids are part of both the nerve cells themselves and their membranes, the myelin substance. As a result of the influence of alcohol, the viability of cells (neurons) is impaired and they become unprotected. The connections between neurons are also disrupted, making the transmission of nerve impulses difficult. This can be seen very clearly in the example of memory loss in a drunk person.

Alcohol has a dual effect on brain cells: it destroys lipids and has a toxic effect.

Fatty substances are also part of the cell membranes of any tissue, in particular blood vessels and blood cells. As a result of damage and partial paralysis of the vascular wall, blood circulation is disrupted.

Red blood cells with a damaged membrane reduce their ability to transport oxygen to tissues. Both lead to insufficient oxygen supply to the brain and the development of oxygen starvation of cells - hypoxia.

The youngest and most vulnerable part of the brain, the cerebral cortex, or the so-called gray matter, suffers the most. It is represented by cells that control the processes of movement, sensitivity, emotions, and actions. It is precisely because alcohol destroys these brain cells that drinkers primarily experience changes in behavior, character and motivation of actions.

Intensity of negative effects on the brain

The effect of alcohol on the human brain has its own characteristics, which are influenced by the following factors:

  • Age, gender;
  • Physical parameters of the body;
  • Strength of the drink;
  • Amount drunk;
  • Calorie content of drinking;
  • Frequency of use;
  • Attitude towards food intake;
  • Health status.

The brains of children and the elderly are most vulnerable to the effects of alcohol. The brain of women suffers to a greater extent due to the structural characteristics of the nervous tissue - it is more sensitive. Height and weight matter: the smaller a person’s weight and height, the more he is exposed to alcohol.

As for the strength of the drink, it is directly related to its quantity. What matters is the total amount per ethyl alcohol. For example, 100 g of cognac with a strength of 40° will have the same effect on the brain as 500 ml of beer with a strength of 8°. The speed of drinking is of great importance.

Rapid absorption of large amounts of alcohol is more detrimental to the brain than the same amount drunk intermittently over a longer period of time.

The alcohol does not have time to be excreted, and its concentration is higher. For the same reason, frequent drinking is much more harmful than occasional drinking; the body does not have time to recover from drinking before a new dose arrives. How alcohol affects the human brain can be found in the video:

Alcohol is more dangerous on an empty stomach. You should eat before taking it, or immediately after taking it. Health status plays a huge role. For example, with liver and kidney diseases, alcohol is less readily excreted from the body. For people with vascular diseases, nervous system diseases, consequences of skull injuries, as well as concussions, alcohol is extremely dangerous.

Physiological consequences of alcohol consumption

Scientists have found that just 100 grams of vodka, entering the body, leads to the death of 8,000 tissue cells of various organs and systems:

  • nervous;
  • cardiovascular;
  • hematopoietic;
  • endocrine;
  • digestive.

Nervous system

The nervous system is the most vulnerable to the influence of alcohol, and the brain is the main target of the effects of alcohol. Alcohol kills brain cells. Of the 8 thousand cells that die from ethanol, the majority are brain cells. It is well known that nervous tissue has the lowest ability to recover, so regular alcohol consumption causes irreparable harm. Read more about how alcohol affects the human nervous system.

The effects of alcohol on the human brain and nervous system lead to the development of chronic diseases such as alcoholic encephalopathy - damage to the central nervous system, alcoholic polyneuropathy - damage to peripheral nerves, and in severe cases, paralysis can develop.

The cardiovascular system

Damage to the vascular wall leads to blood stagnation and the early development of atherosclerosis against this background. Damaged red blood cells adhere to the affected walls of blood vessels, forming blood clots. As a result of exposure to ethanol, all this leads to impaired blood circulation and the creation of conditions for the development of stroke, heart attack, and gangrene of the extremities. Myocardial dystrophy develops in the heart muscle, muscle fibers are replaced by connective tissue.

Blood-forming organs

Alcohol has a toxic effect on the bone marrow and lymphatic system, where the formation of blood elements - red blood cells and white blood cells - occurs. As a result of the influence of alcohol, their number decreases and functional abilities decrease. This leads to anemia and a decrease in the body's protective properties.

Endocrine system

The sex glands are most sensitive to the effects of alcohol. Their hormonal function decreases - both in men and women. Against this background, tumors of the genital area develop, and the ability to conceive decreases. The thyroid gland suffers from the harmful effects of alcohol; a decrease in its function leads to the development of hypothyroidism with a sharp decrease in metabolism. The function of pancreatic insular cells is inhibited, which leads to the development of diabetes mellitus.

Digestive organs

The liver takes the main blow, being the “beating boy” among all digestive organs. Under the influence of ethanol, its cells are destroyed, first replaced by adipose tissue, and fatty liver degeneration develops.

If alcohol intake continues, fatty liver degeneration progresses to cirrhosis - replacement of the parenchyma with scar tissue.

These changes are irreversible. In addition, cancer often develops against the background of cirrhosis. In addition to the listed systems, the genitourinary organs are also affected, their function decreases, an inflammatory process, tumors, and impotence develop. Changes also occur in the musculoskeletal system: cartilage nutrition is disrupted, arthrosis develops, tone decreases and muscle atrophy occurs.

Psychological consequences of alcohol abuse

It is not by chance that such expressions exist: “a drinking person urinates his brains,” or “he drank all his brains away,” and they are close to the truth. Brain cells destroyed by alcohol begin to decompose and toxins are formed.

To get rid of toxins, the body sends an increased amount of fluid to the brain, it flushes them out, and as a result, all cell remains are excreted in the urine. This can explain headaches from a hangover, frequent urination, dry mouth, and increased thirst.

What happens to the cerebral cortex, which regularly loses its cells? It gradually atrophies and decreases in volume. Accordingly, its functions are also lost. Initially, this manifests itself as psychological disorders, which are gradually replaced by deeper, mental disorders.

Psychological disorders from the effects of alcoholic beverages

There is an expression: “he is in the subcortex,” as they say about a disinhibited person. The subcortex is usually called the accumulation of nerve cells located under the cortex of the hemispheres; they contain the centers of natural instincts, emotions, and sensitivity.

The cerebral cortex has a regulatory effect on these centers and inhibits their activity.

When the cells of the cortex die, the subcortex is disinhibited, a person’s behavior changes, his attitude towards the world around him and his assessment of himself in it.

These are psychological disorders under the influence of alcohol.

They manifest themselves depending on alcohol, the overwhelming desire to drink in order to have fun, to relax, regardless of the environment. Such people become self-confident and assure everyone that they will quit at any moment. In fact, they are becoming increasingly dependent.

Further, when they cause problems in the family and at work, a feeling of guilt appears. But instead of correcting the situation, they again resort to alcohol in order to drown out this feeling. Subsequently, it gradually disappears and, on the contrary, the drinking person begins to blame his loved ones for his drinking.

Memory decline occurs very quickly, even to the point of “failures.” The drunken high and euphoria give way to depression, which prompts them to drink again. Irritability, lack of restraint, rudeness and often aggressiveness appear.

A person becomes asocial, ceases to take into account those around him, is capable of easily offending, stealing, just to drink again. This is how psychological dependence and alcohol degradation of personality are formed.

The effect of alcohol on the human psyche

From the effects of alcohol, mental disorders in drinkers are varied. This can be deep depression, often with suicidal attempts, or, conversely, aggressiveness to the point of committing crimes. Most often, the psyche suffers when an alcoholic tries to quit, reduces the dose, or simply cannot find something to drink.

Withdrawal syndrome develops—alcoholic delirium, the so-called “delirium tremens.” Its characteristic manifestations are visual and auditory hallucinations, most often of a zoological nature.

It is during delirium tremens that drinkers most often die.

The patient sees various animals, insects, and a feeling of fear and delirium arises. The effect of alcohol on the autonomic nervous system is expressed by the following disorders: drop in blood pressure, cold sweat, palpitations, uncontrollable trembling. In severe cases of hangover, seizures may develop.

Features of the influence on adolescents

Teenage alcoholism is an extremely serious problem. A fragile, immature psyche is very susceptible to the effects of alcohol and the formation of addiction. Active metabolism and high hormonal levels in adolescents only create favorable conditions for alcohol intoxication.

The cells of the cerebral cortex that have not yet matured are very quickly destroyed, and personality degradation occurs just as quickly, and mental abilities sharply decrease.

Alcohol addiction in adolescents develops very quickly, and all the consequences associated with it are much more severe than in adults.

If qualified assistance is not provided in the first 2 years of drinking alcohol, then the hope for a cure in the future is very doubtful.

Recovery of brain cells after quitting alcohol

Do brain cells recover after quitting alcohol? Nerve cells have the ability to recover, but this process is very slow, and one cannot count on a complete renewal of the cortex. And all drug treatment practice suggests that after just a year, a person who has stopped drinking changes significantly. Memory, thinking abilities, behavior in family and society improve.

In order for the recovery process to be more successful, you must strictly adhere to the following rules:

Even the most seemingly hopeless drinkers always make sense to stop before tragedy occurs. Specialists will provide psychological and medicinal assistance, which, coupled with the patient’s wishes, will certainly have an effect.

How to reduce the negative effects of alcohol before a feast

Life is life, and there are often situations in it when you have to “sip” at least a little. To prevent alcohol from having such a detrimental effect, you need to prepare in advance. 4-5 hours before the upcoming drink, you need to drink a small amount of alcohol and eat a hearty meal.

This is the so-called alcohol vaccine; it promotes the production of the enzyme alcohol dehydrogenase, which destroys alcohol. The body will be prepared for the new dose, and it will not be so dangerous.

The “vaccination” can be done by replacing alcohol with 1 tablespoon of Eleutherococcus (medicinal plant), and if you have high blood pressure, you need to drink hawthorn tincture.

To reduce the absorption of alcohol before the banquet, you need to eat a hearty sandwich with butter, drink a raw egg, strong coffee or tea with lemon.

If preparation was not possible, then the following rules must be followed:

  • Drink in small doses, spread over time;
  • Do not mix different drinks, give preference to one;
  • It’s good to have a snack, not forgetting about greens and citrus fruits;

Immediately before and immediately after a feast, it is good to drink Nutriclins, Zorex or glutargin; they help remove alcohol faster and reduce its toxic effect. Alcohol consumption should be avoided. Temporary “relaxation” can cost the health and even the life of the drinker and his loved ones.

Drinking alcohol, even in small dosages, has a detrimental effect on the functioning of almost all systems of the human body. Thus, the effect of alcohol-containing drinks on the brain deserves special attention: one of the negative consequences of prolonged use of strong drinks is blood agglutination (adhesion of red blood cells), leading to a disruption in the processes of nutrition and respiration of the cells of the main organ of the nervous system. Find out what else is fraught with regular alcohol consumption.

What is alcohol

This term can be used in two senses. Firstly, alcohol is ethyl alcohol, which is a colorless liquid substance with an extremely specific odor. This substance is actively used in medicine as a disinfectant. Secondly, alcohol is usually understood as a variety of alcoholic beverages obtained naturally or artificially. The latter are often used systematically by individuals, which has very unpleasant consequences for human health.

The effect of alcohol on the human nervous system

When drinking alcohol, the brain receives signals from the stimulating acid (glutamate) it contains, which, when it enters neuron receptors, disrupts speech, coordination, and creates a distorted perception of existing reality. In addition, the negative effect of alcohol on the human brain causes inhibition of cognitive functions. In the scientific community, this condition is usually called alcoholic myopia.

An additional aspect of the harmful effect of alcohol on the human nervous system is the narrowing of the focus of perception of information received from the outside. The inability to fully analyze any situation makes a drunk person inadequate. Thus, in a sober state, a subject of social relations can restrain his ardor while being next to an aggressive interlocutor.

A drunk person completely loses the ability to interpret the situation in a broader context, becoming an asocial person without any moral barriers. On top of that, the situation is complicated by the fact that drunk people tend to perceive the actions of the objects of their antipathy as deliberately thought out and intentional. For this reason, noisy feasts often end in a showdown.

How alcohol affects the brain

With prolonged use of alcohol, disruption of the centers responsible for cognitive abilities develops. When answering what happens to the brain when drinking alcohol, experts mention memory and attention disorder syndromes. The toxic effect of 40% ethanol has a suppressive effect on the cellular structures of the main organ of the central nervous system. Moreover, 100% alcohol affects the brain in a destructive way. In addition, prolonged intake of ethanol leads to a lack of vitamin B1, without which areas of the brain cannot function properly.

The effect of alcohol on blood vessels

It is known that strong drinks tend to thin the blood, which is even useful in some situations. Meanwhile, the effect of alcohol on blood vessels is such that with prolonged use, the opposite situation occurs. Against the background of regular intake of ethanol into the body, the integrity of the erythrocyte membranes is disrupted, leading to their gluing. Due to the presence of red cell clots in the blood, areas of thrombosis begin to form in the vessels.

As a result of arterial obstruction (blockage), brain hypoxia occurs, externally manifested by sensations of excitement and intoxication. In addition, ethyl alcohol increases the permeability of capillaries, which creates a risk of developing edema of the main organ of the central nervous system. During autopsies of people who died from alcohol addiction, experts found that ethanol leads to the following changes in the brain:

  • the occurrence of multiple hemorrhages (due to obstruction of blood vessels by adhered red blood cells);
  • smoothing out convolutions;
  • reduction in organ volume.

Effect of alcohol on memory

Drinking alcohol negatively affects the functioning of the hippocampus. The adverse effects of alcohol on the brain negatively affect memory and attention. It is worth saying that the irregular intake of ethanol into the body gives the body time to eliminate the toxic effects of this substance. With a regular influx of alcohol, the negative effect of alcohol on memory is aggravated, and the person gradually degrades. Over time, the solution to all problems for a drinker moves into a glass of alcohol.

Features of the influence of alcohol on a woman’s brain

During clinical studies, it was found that women who drink strong drinks are more susceptible to pathologies of the liver, heart, and other organs. In addition, the particular effects on a woman’s brain are determined by the increased emotional sensitivity of the weaker sex. Drinking alcohol during pregnancy requires special consideration. Such a rash act by the expectant mother can lead to serious pathologies in the development of the fetus.

What determines the intensity of the negative impact on the brain?

Alcohol abuse is the foundation for the development of many pathological processes in the body. The harm of ethyl alcohol can be proven without any medical research. A person under the influence of alcohol is characterized by inappropriate behavior, incoherent speech, and confusion. The focus of perception of such a subject shifts from distant tasks towards closer ones, which often only worsens the situation. The intensity of the effect on the brain depends on the following factors:

  • general health;
  • quantity and quality of alcoholic drinks consumed;
  • alcoholic age;
  • the duration of the period of regular drinking;
  • the body's ability to recover.

What brain diseases does alcohol cause?

Alcohol abuse often leads to irreparable impairment of a person’s cognitive abilities, which is expressed in the loss of clear thinking, a decrease in the level of mental development and other negative consequences. It is important to note that the brain suffers from weak alcoholic drinks in the same way as from strong ones, so you should not think that long-term drinking of wine or beer does not threaten your health. Regular alcohol consumption leads to the following serious illnesses:

  • dementia;
  • Korsakoff's disease;
  • encephalopathy of alcoholic origin;
  • paranoia;
  • hallucinosis;
  • apathy;
  • delirium of jealousy.

Everyone knows about the dangers of alcohol. Excessive consumption causes health problems, leads to family discord and moral decay of a person. Problems caused by alcohol are not only physiological, but also psychological in nature - this is the so-called alcohol dependence, leading to encephalopathy and edema. The brain of an alcoholic is significantly different from that of a sober person.

Harm caused by alcohol

The greatest harm to the body is caused by ethanol, a toxic substance that poisons almost all organs and is the main cause of serious diseases. Ethanol poisoning leads to encephalopathy and permanent swelling, and even death in abusers. Affected organs include:

  1. Cardiovascular system: Alcohol destroys red blood cells, which leads to toxic hemolytic anemia and cardiac arrest, the development of arrhythmia and cardiomyopathy. Internal hemorrhages also occur, and the formation of blood clots increases, which can subsequently clog the vessel and cause intracerebral edema, stroke or heart attack.
  2. Stomach and gastrointestinal tract: Damage occurs to the mucous membrane of the stomach and small intestine, the absorption of water and substances is impaired, and severe swelling occurs. Long-term use can lead to cancer of the esophagus, stomach or rectum, and the development of gastritis.
  3. Genitourinary system: ethanol poisons the reproductive cells, easily penetrates the ovaries, sperm, and also passes through the placenta and enters milk.
  4. Liver: when drinking alcohol, the liver is poisoned, some of the cells die, and fat cells form in their place. This leads to a decrease in the useful volume of the liver and an increase in the load on the remaining cells, inflammation and the formation of liver cirrhosis and edema.

Also, the effect of alcohol can provoke cancer, diabetes, cerebral encephalopathy, edema, various forms of cancer and diseases associated with the cardiovascular system. The health forecasts for abusers are very negative.

The effect of alcohol on the brain

The most powerful effect of even small doses of alcohol is on the brain. It is enough to note that with a blood alcohol concentration equal to one part, the liver contains 1.45 parts, the cerebrospinal fluid contains 1.5 parts, and the brain contains 1.75 parts, that is, almost two times. Immediately after alcohol enters the stomach, it enters the bloodstream and is transferred to the skull, where it begins to poison cells, leading to encephalopathy and edema.

Negative properties that cause harm include:

Studies have also shown that the brain of an alcoholic is significantly different: their nerve cells had altered nuclei and protoplasm, that is, they were no longer able to return to their normal state. Encephalopathy occurs.

A particular danger lies in its narcotic properties: the brain does not die easily, but also begins to require a second dose. There is no need to even talk about the dangers of this.

What happens to the brain when alcohol enters and what is the result?

Alcohol affects the brain in the following ways:

  1. Ethanol exposure leads to the death of neurons in the cerebral cortex and cerebellum;
  2. Then they die off, mental activity decreases, brain volume and memory decrease, and there is a high probability of edema;
  3. Dead cells begin to rot inside the brain, leading to headaches and hangovers;
  4. To cleanse itself, the brain pumps large amounts of water through itself (hence morning thirst and frequent trips to the toilet).

The result of regular alcohol consumption is deplorable: while most organs are able to recover and revive dead cells, the brain is incapable of this. Its cells die completely along with the information stored inside. This leads to a variety of consequences:

  1. The process of personality degradation begins;
  2. There is a deterioration in memory and intelligence, with a particularly strong impact on short-term memory;
  3. The processes of long-term memorization are deformed;
  4. The activity of the entire nervous system is disrupted;
  5. The brain decreases in volume, “dries out,” and begins to decompose—this is especially noticeable in alcoholics.

On average, 100 grams of vodka kills 8 thousand cells. Poisonous substances are eliminated from the body within 20–30 days.

Complete recovery of brain cells may take several years, but this probability is extremely low. It is necessary to completely give up any alcohol so that the cells can return to their usual volume.

The effect of alcohol on memory and mental activity

Alcohol consumption not only interferes with the functioning of the brain, but also reduces mental activity, which leads to personality degradation and encephalopathy. The changes that occur are practically not subject to subsequent adjustments; it can be quite difficult to fully recover, that is, the damage caused turns out to be extended over time:

  1. Mental activity slows down, especially complex mental processes;
  2. It is worth noting that false “brilliant” conversations and the search for solutions are a consequence of the deterioration of brain activity: a person does not become smarter, the brain simply suggests a simpler solution, since it is not able to come up with a more complex one;
  3. The process of criticism and judgment weakens, but there is an increase in feelings of self-confidence and boasting;
  4. The reasons described above lead to increased sensitivity and emotional component: this includes unexpected confessions and intimate conversations.

Alcohol abuse provokes pathological changes in the brain: smoothing of convolutions, reduction in its size, resulting in the development of such dangerous diseases as alcoholic epilepsy and encephalopathy. It is a scientifically proven fact that alcohol has a negative effect on the human brain, and complications often arise even as a result of taking small doses of alcohol.

The mechanism of alcohol's effect on the brain

Alcohol contains substances that poison the entire body and disrupt its functions. The brain also suffers, in which various cells begin to die. Ethyl alcohol enters here through the vessels from the stomach, instantly attacking the cerebral cortex and disrupting its functions. As a result, a state of alcoholic intoxication develops, accompanied by damage and death of cells in different parts of the brain:

  1. In the occipital part with the vestibular zone.
  2. At the moral center.
  3. In the hippocampus.

Damage to nerve cells in the area of ​​the vestibular apparatus causes deterioration in coordination, as a result of which a drunk person develops a characteristic gait. The death of cells in the moral center leads to emancipation, the loss of feelings such as shame and fear. Under the influence of alcohol, the cells of the hippocampus responsible for memory also die. As a result, the next morning a person cannot reconstruct yesterday’s events: what he did, where he managed to visit.

Normally, blood in the brain circulates through very thin vessels and capillaries, due to which a sufficient volume of oxygen is supplied to each part of the organ. However, alcohol creates significant obstacles to normal blood circulation: the ethyl alcohol it contains constricts blood vessels and sticks red blood cells together, which promotes the formation of blood clots. Microscopic capillaries become clogged, and cells begin to experience oxygen starvation and die. At the same time, a person feels euphoria and does not even suspect the development of pathological processes.

Effects of drinking alcohol on the brain

If the liver is capable of regeneration after alcohol withdrawal, then the cells of the gray matter are not restored. How strongly alcohol affects a person’s brain always depends on the doses of alcohol: the larger they are, the faster personality degradation occurs. The patient himself does not notice the negative effects of alcohol, since the state of intoxication is accompanied by mild euphoria. However, pathological studies of deceased alcoholics confirm that systematic alcohol abuse causes irreversible changes:

  1. Decrease in organ size.
  2. Formation of voids.
  3. Straightening the convolutions.
  4. The appearance of microscopic hemorrhages.

For your information:

Even a single dose of alcohol causes damage and death of brain cells. The negative effect on the brain increases with liver disease, since it is in this organ that the breakdown of ethyl alcohol occurs.

With the help of many years of research, scientists were able to prove that when drinking 100 g of vodka, 8,000 brain cells instantly die. At the same time, the structure of the organ is damaged, which decreases in size and becomes covered with scars and ulcers. Under a magnifying glass, an alcoholic's brain looks like the lunar surface with its many craters.

Cognitive impairment

The destructive effect of alcohol on the human brain begins with the first glass, resulting in a decrease in the field of perception and other cognitive impairments. The person loses the ability to make an objective assessment and suffers from hallucinations that do not go away even after sobering up. Ethyl alcohol causes the most severe damage to the cerebral cortex, which is responsible for higher nervous activity. In this case, characteristic symptoms are observed:

  • foggy thoughts;
  • decreased IQ;
  • cheeky behavior, lack of shame;
  • impaired coordination of movements;
  • memory impairment and confusion.

Ethyl alcohol also affects the pituitary gland and hypothalamus, which reduces the production of vital hormones. The body gradually gets used to and adapts to the constant supply of alcohol, slowing down mental activity, “turning off” memory, attention, moral principles and creativity.

What brain diseases does alcohol cause?

Due to the harmful effects of alcohol on the human brain, severe physical and mental illnesses are formed, which cause disability. Pathological processes are based on two main factors: the neurotoxic effect of alcohol and vitamin B1 deficiency, without which normal brain functioning is impossible. For these reasons, particularly severe and dangerous diseases develop:

  1. Alcoholic encephalopathy.
  2. Alcoholic epilepsy.
  3. Korsakoff's disease.

Signs of encephalopathy appear at the last stage of alcoholism: the patient becomes emotionally unstable, indifferent to everything, and constantly experiences weakness. Symptoms of alcohol-induced epilepsy only occur during a hangover, and if they become regular, the person develops dementia. Since attacks are spontaneous and may be accompanied by fainting, alcoholics are prohibited from climbing to heights, swimming in rivers and driving vehicles.

With Korsakoff's disease, there are signs of encephalopathy, dementia and polyneuritis. A person completely ceases to navigate in time and loses the ability to perform any arithmetic operations. Muscle atrophy gradually sets in, leading to severe disability. The patient can no longer care for himself and requires outside care.

For your information:

With constant consumption of alcohol, the structure of neurons is destroyed and connections between them disappear. As a result, the alcoholic not only has a decrease in intelligence, but at a certain point he completely degrades as a person.

Mental illnesses arising from alcohol abuse are detected in all alcoholics, although the pathologies themselves differ in diversity. Starting with insomnia and irritability, mental disorders progress and serious illnesses develop:

  1. Delirium tremens.
  2. Alcohol paranoia.
  3. Hallucinations.
  4. Delirium of jealousy.

Delirium tremens, also known as delirium tremens, develops after coming out of a long binge and is characterized by a pronounced clouding of consciousness - a person becomes dangerous to himself and to society. Paranoia and hallucinations also arise after a sudden cessation of alcohol: the patient hears certain voices that often threaten him, causing severe fear. Delusions of jealousy always occur in a chronic form, and only in old age do its manifestations weaken. The patient is jealous of his partner, provokes scandals, uses threats and physical force.

Brain swelling

The most severe complication after drinking alcohol is cerebral edema, which occurs as a reaction of the body to severe intoxication. Due to the high permeability of the vascular walls through which blood circulates, excess fluid accumulates in the brain tissue. This condition occurs with characteristic symptoms:

  • headache;
  • nausea and vomiting;
  • dyspnea;
  • loss of sensation in some areas of the body;
  • coordination problems;
  • convulsions;
  • fainting;
  • memory impairment;
  • difficulty speaking;
  • high pressure;
  • paralysis.

The disease develops even due to moderate alcohol consumption. The provoking factors in this case are the general condition of the body, the stage of alcoholism, and individual characteristics. Depending on the location of the edema, it can affect vital centers of the brain, which directly threatens a person’s life. The only prevention of complications is a complete abstinence from alcohol-containing drinks.

In Russia alone, about 80,000 people die every year from the consequences of drinking. They are poisoned by surrogates, suffer strokes and heart attacks, freeze in cold snowdrifts, and die from liver failure. And what are the memory loss and ugly behavior, and the appearance of an alcoholic?

Alcohol destroys not only self-awareness, ethanol mercilessly deals with the human brain, turning a person into a real faceless animal. The negative, destructive effect of alcohol on the human brain, unfortunately, in most cases is irreversible.

Ethyl alcohol destroys all parts of the brain

The structure of the human brain is extremely complex. The brain consists of five parts, which are interconnected by billions of neurons (nerve cells). Nature has provided natural protection for this sensitive and very fragile system. The medulla is protected from blood flow by a certain physiological barrier.

The natural blood-brain barrier, which successfully protects the brain from the penetration of viruses, bacteria, and toxins, is not able to save it from ethyl alcohol.

Ethanol, being an excellent solvent, penetrates into the brain matter without any problems through all existing membranes. Once there, ethyl alcohol acquires extremely low enzymatic ability. That is, the breakdown of alcohol compounds to acetaldehyde in the medulla is extremely slow.

Ethanrol easily penetrates the protective membrane of the brain

Given the ability of neurons to accumulate (accumulate) ethanol metabolites, the brain will retain the remains of alcohol even after a month. Let's look at how alcohol affects the human brain, in particular its parts.

Cerebellum

This structure is responsible for the sense of balance and coordination of all movements. Alcohol metabolites accumulate the most in the cerebellum, causing serious harm to this department. This explains the awkward gait of a drunken person and his lack of balance.

Cerebral cortex

This department is responsible for the individual’s ability to plan something, be responsible for their actions, think and reason. Ethanol, even in minute quantities, is detrimental to this department, causing:

  1. Memory impairment.
  2. Loss of concentration.
  3. Problems recognizing objects.
  4. Decreased intellectual capabilities.
  5. Inability to judge the distance to objects.

The prolonged effect of alcohol on the brain leads to complete personality degradation. The cerebral cortex, due to the massive death of neurons, ceases to function normally, and the person “loses his face”.

Alcohol affects all parts of the brain

Medulla

The individual’s ability to breathe, regulate temperature and be aware of reality depends on the healthy functioning of this department. What happens if the neurons of a given brain region die? A person’s temperature drops, he experiences severe drowsiness and dizziness, and may lose consciousness. It is for this reason that tipsy people freeze on the street, falling into snowdrifts.

What happens during a hangover

How do events unfold after massive neuronal death? The hangover phase begins, accompanied by a number of unpleasant symptoms. A person is especially tormented by thirst and headache. These processes occur due to the body’s active attempts to get rid of the accumulation of dead neurons.

With a hangover, intracranial pressure increases, which provokes an influx of fluid and the development of a severe headache. All this is evidence of the body’s attempts to remove dead neurons.

Ethanol affects not only parts of the brain, but also its blood vessels. Under the influence of alcohol metabolites, they sharply expand and then contract. This dangerous situation can lead to blood vessel rupture and stroke. A person faces disability, and in severe cases, death.

How does alcohol affect the brain?

In addition to deadly thrombosis, ethanol metabolites cause a huge number of various disorders associated with the functioning of the brain. A person who abuses alcohol faces an impressive list of major pathological changes that negatively impact the personal identity and behavioral reactions of the drunkard:

  1. The center responsible for morality is destroyed. That is, people dependent on alcohol forget about moral values ​​and culture of behavior. Even a small dose of alcohol dulls a person’s sense of shame and completely liberates him. And prolonged drunkenness leads to a complete loss of all moral principles.
  2. There is a global disturbance of the vestibular apparatus. A person loses a sense of reality and a sense of balance.
  3. Alcohol kills brain cells responsible for memory. Often, after particularly stormy parties, many individuals cannot remember all the events of the past holiday. These are echoes of global brain poisoning with alcohol metabolites.

Alcoholism and the cerebral vascular system

If a person suffers from chronic alcohol addiction, the activity and functioning of the brain centers gradually fades. This immediately affects the ability to remember, think and understand. But this situation is not so bad. Under the influence of ethanol metabolites, irreversible changes occur in the vascular structure of the brain.

What does a brain damaged by alcohol look like?

What does this mean? Various mental disorders. Alcohol has different, but always detrimental effects on the blood vessels of the brain. Ethanol breakdown products:

  • destroy the brain regions that respond to the regulation and stabilization of vascular tone;
  • upset endocrine functions, forming obesity or exhaustion, atrophy of the reproductive system, and neuropsychic disorders;
  • disrupt the functioning of the autonomic system, which leads to allergies, neuroses, problems in the gastrointestinal tract, skin diseases, pain in the joints and muscles.

All these changes ultimately lead to the formation of hypertension, hypertensive crisis and various vascular pathologies of the brain. The risk of cerebral edema increases significantly.

Even a small dose of alcohol leads to irreversible consequences in the functioning of the brain.

Pathologists working with chronic alcoholics often note various changes in the brain structure at autopsies of people who died from drinking. Namely:

  • numerous hemorrhages;
  • a sharp decrease in the volume of the entire brain;
  • smoothing and disappearance of cerebral convolutions.

What happens to the brain when drinking alcohol is that it literally dries out, significantly decreasing in size. And what happens to the person himself? Complete degradation of personality without the right to recovery. Moreover, even moderate and light drinkers mercilessly destroy their own brains.

What diseases come

The negative, destructive effect of alcohol on the brain and nervous system is truly colossal. Ethanol is a powerful toxic compound; it destroys the functioning of all internal systems and organs, provoking the development of many diseases, most of them fatal.

The mechanics of the development of these pathologies is based on the massive death of neurons, brain cellular structures and a major deficiency of vitamin B1 (thiamine). This vitamin is extremely important for the normal functioning of all parts of the brain. What pathologies can threaten a drinker of alcoholic beverages?

  1. Alcoholic encephalopathy. Severe brain pathology of organic nature. This disease, occurring against the background of global memory impairment, mental problems, apathy and complete indifference to everything, indicates that the patient has the last stage of alcoholism.
  2. Korsakoff's disease. A disease that occurs on the basis of the development of dementia, amnesia and the simultaneous addition of polyneuritis. Such patients are unable to answer trivial questions about what year it is and what time it is. They cannot solve the simplest problems and do not remember their name. With this disease, complete depletion of muscle tissue occurs, the person loses the ability to move and becomes disabled.
  3. Alcoholic epilepsy. A seizure condition in a patient occurs with this disease only against the background of a hangover syndrome. With numerous epiconvulsions, a person gradually develops complete dementia and personality degradation occurs.
  4. Delirium. This disease is better known as “delirium tremens”. As a rule, it develops with a sudden and sharp refusal of alcohol. While under attack, an alcoholic poses a great danger both to himself and to the people around him. In this case, the patient needs emergency hospitalization.
  5. Hallucinosis. A condition that occurs against the background of alcoholism, in which the alcoholic clearly hears voices and experiences hallucinations. This condition usually develops during abstinence and requires urgent and long-term treatment.
  6. Paranoia. Formed against the background of a sudden refusal of alcohol. But in its manifestations and symptoms, this pathology is more similar to delirium tremens or hallucinosis.

Often, with alcohol addiction, various neurotic disorders develop. A person is plagued by global problems with sleep, up to complete insomnia and the development of hallucinations as a result of this. Alcoholism destroys both the physical/mental brain functions and the cognitive capabilities of the individual (problems with the ability to express one’s thoughts, reasoning abilities, logical perception, etc.).

Does the brain recover after quitting alcohol?

The first to suffer from ethanol metabolites are the brain functions responsible for memory, thinking potential and intellectual level. Unfortunately, it is not possible to completely revive dead neurons in these areas. But partial recovery is quite possible.

Comparison of the brain of a healthy person and an alcoholic

The human brain is a very flexible structure. The brain regions are able to restore the functioning of damaged areas through the formation of new neural connections.

The first sign that the brain has begun to recover is the disappearance of depression symptoms. Memory gradually improves, the mind becomes more flexible, and intelligence increases. Brain recovery after quitting alcohol takes on average about 1-1.5 years. Of course, provided that you completely stop drinking alcohol and recover from alcoholism.

But with the return of the ability to navigate, sense space and have visual recognition (the ability to create a mental image in the mind), things are much worse. The brain areas responsible for such abilities die in the last stages of alcohol addiction.

It will take 4-5 years to restore these areas of the brain. And then only on condition of long-term work on yourself. The best results can be achieved by adding special brain training exercises to the rehabilitation program. These classes are conducted by a psychotherapist, but they also need to be done at home.

But these improvements are not guaranteed. It all depends on the degree and duration of alcohol abuse, as well as on the initial state of the person’s health. When pathological changes occur in the brain (if a person continues to drink), disturbances develop in the functioning of the spinal cord and medulla oblongata. In this case, the result of alcoholism is coma and subsequent death of the person.
