Scientific facts about the effect of alcohol on the human brain - does it destroy neurons and cells? The effect of alcohol on the nervous system and brain.

In this article, we will try to tell only about a small list of problems that alcoholism leads to, if we consider this disease in the context of the impact on the most important human organ - the brain.

Alcohol greatly affects our brain and nervous system . Let's look at the specific elements that are most impacted.

At regular use alcohol in humans:

Speech deterioration. It is harder for a drunk person to link words in a sentence and harder to pronounce them;
Deterioration of coordination . A drunk person does not have 100% control over his body. It becomes harder for him to move;
Distorted reality . For a drunk person, reality is not real. He sees the world differently. He may not realize the seriousness of the situation. This occurs because when drinking alcohol, the brain receives signals from the stimulating acid it contains;
Deterioration cognitive functions of the brain ;
Narrowing your focus perceived information. It is very difficult for a drunk person to concentrate, it is difficult to listen and generally perceive any information;
A person who has consumed wine or vodka (and, in fact, any type of alcoholic drink) has no opportunity to sanely and adequately assess the situation . Again, because his reality is not real;
Increased aggression . For drunk people, all moral barriers disappear. Therefore, noisy feasts often end in fights.

So remember before you decide to drink. Such imaginary happiness is not worth the problems it can lead to.

With prolonged use of alcohol, a person is impaired work of brain centers , which is responsible for cognitive abilities, memory and attention deteriorate. People who abuse alcohol experience vitamin B1 deficiency , due to this deficiency the organ does not function properly. It is worth noting that a low-grade drink is no less harmful.

If you do not stop regularly drinking alcohol in time, then this can lead to such diseases , How:

dementia;
Karsakov's disease;
encephalopathy of alcoholic origin;
paranoia;
hallucinations;
apathy.

If you can’t live without alcohol, then know that there are certain consumption standards alcohol per day.

Narcologists say that with such standards the body will not feel bad. However, safe doses of alcohol depend on the individual capabilities of the body. Therefore, it is better to consult a doctor. Below are the average standards.

For men from 30 to 40 with a weight of 75 kg:

beer- 0,5 liters;
fortified wine - 200 gram.

For women from 25 to 35 with a weight up to 70 kg:

beer- 0,3 ;
fortified wine - 150 gram.

However, it is worth remembering that even such alcohol consumption in the long term , will backfire on you and your brain.

The earlier a teenager starts drinking alcohol, the faster the thinking organ is destroyed. All those problems that are typical for adults typical for teenagers . But due to the fact that it is during adolescence that the brain and central nervous system complete their development, this has a more detrimental effect on a person.

Due to high metabolism alcohol is absorbed faster into the circulatory system and, increasing its destructive effect, destroys the teenager’s brain:

Coming delay intellectual and emotional development;
Comes almost instantly degradation personality;
Neurological and mental deviations;
Very fast addiction to alcohol develops.

Addiction formed in two to three years regular alcohol consumption. In order not to treat the child’s addiction later, you need to think about it now.

Psychologist's advice! If you often drink alcohol and your child has started doing the same, then show by example that there are things more interesting and entertaining than alcohol. First of all, give up all types of alcohol-containing drinks yourself. Secondly, try to walk more, go to the cinema, play sports games. Thirdly, help your child find interests and hobbies. If he has an interesting pastime, he will have no time left for drinking.

Remember, children always take example from your parents . Who your child becomes depends only on you.

There is no danger to the body, the habit of drinking is typical for many people, but in the specified quantities and with the specified parameters of the patient, it does not cause any harm to the body. Many people relieve stress with alcohol on holidays and after work, but are not addicted to it.

The patient sees alcohol as a way out of difficult situations and resorts to hard drinks more and more often. This stage is dangerous because in any difficult situation in life, this stage can smoothly transition into the next one, which is much more dangerous to health.

At this stage, an addicted person can no longer do without alcohol, but is firmly convinced that he is able to quit at any time, but not today. Already here complications with the liver and other difficulties with organs and well-being may begin.

Special treatment and a short course of rehabilitation, plus the support of relatives, can bring you out of this stage. This stage can provoke very serious problems with the liver and other organs, which will lead to illness for the rest of life.

This stage is not hopeless, but it requires an extremely serious approach to treatment and a long period of rehabilitation, with regular medical procedures, many medications and, often, expensive treatment.

The effects of drinking alcohol on the brain

Long-term and regular use of alcohol leads to to the death of billions of nerve cells . After only 4 years, the brain of a drunkard decreases in size, which has a bad effect on a person’s mental abilities. Also, the weight of the organ also decreases - he dries up.

Organic lesions of an alcoholic's brain affect the functioning of the main functions, incl. thinking:

Elementary becomes difficult brainwork , the criticality of thinking decreases, the thought process itself narrows and worsens.
Character deteriorates, prevails irritability , aggression.
Due to the release of large amounts of dopamine when consuming various alcoholic beverages, ethanol is formed fast addiction , alcoholism occurs, which is difficult to treat.
Regular consumption of alcohol leads to a complete shutdown of highly organized brain structures. Human activity becomes subject to the subcortex, drunkard deteriorates as a person .

Rise above it all do not abuse wine, vodka, cognac and beer drinks . If you have such problems, then there is no need to despair.

Doctors say that you can return to a full and healthy life only after complete abstinence from alcohol , while the brain recovers completely within a couple of years.

You there is a chance to return to a fulfilling life. In the next paragraph we will examine treatment methods in more detail.

Treatment options

In modern medicine there are many ways to get rid from alcohol addiction:

hemming;
coding;
hypnosis;
hardware impact;
psychotherapy;
various non-traditional methods of treatment.

Let's look at each method in more detail, remembering that only after being cured can you get your brain back in order:

Hemming. Binding for drunkenness is one of the old treatments. A certain drug is sewn under the skin or injected intravenously into the patient. If a person drinks, the drugs release toxic substances that lead to vomiting and nausea. The goal of this method of treating alcoholism is to create in the patient an aversion to alcoholic beverages.
Coding. One of the most effective methods of treating addiction is coding - emotional stress psychotherapy. With the help of mental influence on the patient, a ban on alcohol is created. Using an emotionally stressful conversation, the doctor convinces the patient that even if he drinks small amounts of alcohol, he will face serious, dangerous consequences that threaten his life.
Hypnosis. In the treatment of a bad habit, hypnosis is used, which gives good results, but is not suitable for everyone. If a person is not suggestible, the session will not help to give up alcohol. In a state of hypnosis, the patient is instilled with disgust or indifference to alcoholic beverages and severe consequences after consuming it. The complexity of the method is that the patient must come to the appointment as a completely sober person, otherwise he will not perceive the information. For people less susceptible to hypnotherapy, physical measures can be used.
Hardware Impact - a modern method of treating alcohol addiction using special medical equipment that acts on the patient’s brain. With the help of this treatment, the functioning of the organ is restored and the activity of the centers responsible for the desire for alcohol is blocked. The desire to drink is eliminated and the patient can start life anew.
Psychotherapy has long established itself as an effective way to treat addiction. This includes Malkin’s original treatment methods, Rozhnov’s psychotherapeutic method, collective sessions and other techniques. The patient is influenced by psychotherapeutic guidelines to maintain an emotional-volitional state. Can be used independently and in parallel with other treatment methods. For the rehabilitation process to be more effective, the patient’s family must participate in it.
Other rehabilitation methods other than coding include traditional medicine recipes . Since ancient times, people have been treated for alcohol addiction with the help of herbs and plants. Some medicinal herbs reduce the desire for certain drinks, such as: creeping thyme, centaury, St. John's wort, wormwood, angelica. They are not considered a complete remedy for drunkenness, but their use helps support the body during difficult periods and restore strength.

Do not forget that the person himself is very difficult to decide on treatment .

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:

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.
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.
Genitourinary system: ethanol poisons the reproductive cells, easily penetrates the ovaries, sperm, and also passes through the placenta and enters milk.
Liver: when drinking alcohol, liver poisoning occurs, 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 cirrhosis of the liver and its edema.

Also, the effect of alcohol can provoke oncological diseases, 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. Suffice it to say that when the concentration of alcohol in the blood is equal to one part, the liver already contains 1.45 parts, the cerebrospinal fluid - 1.5 parts, the brain - 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 the 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 demand 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:

Ethanol exposure leads to the death of neurons in the cerebral cortex and cerebellum;
Then they die off, mental activity decreases, brain volume and memory decrease, and there is a high probability of edema;
Dead cells begin to rot inside the brain, leading to headaches and hangovers;
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:

The process of personality degradation begins;
There is a deterioration in memory and intelligence, with a particularly strong impact on short-term memory;
The processes of long-term memorization are deformed;
The activity of the entire nervous system is disrupted;
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:

Mental activity slows down, especially complex mental processes;
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;
The process of criticism and judgment weakens, but there is an increase in feelings of self-confidence and boasting;
The reasons described above lead to increased sensitivity and emotional component: this includes unexpected confessions and intimate conversations.

From this article you will learn about the scale of the tragedy called alcoholism, as well as:

The scale of the tragedy

Unfortunately, recent studies confirm the high dangers of alcohol. Thus, research by David Nutt, a famous psychiatrist and pharmacologist, identified alcohol as the most dangerous substance, with a clear negative effect on a person’s psychological and physical health. The scientist found that prolonged consumption of alcohol has a greater effect on the body than the use of hard drugs, LSD and other hallucinogens. Have you ever thought about how many people drink?

Some statistics

More than 85% of people on planet Earth have consumed or regularly consume alcohol;
Every fourth adult resident of Russia suffers from domestic alcoholism;
65% of adolescents under 13 have tried alcohol;
40% of minors aged 13-18 regularly drink alcohol;
According to WHO estimates, Russians consume more than 15 liters of pure ethyl alcohol per capita per year;
For comparison, at the beginning of the 19th century in Russia, consumption did not exceed 3.5-4 liters per capita.

To summarize, according to WHO data for 2014, every second person drinks alcohol periodically. If we take the total damage to humanity, the years of exposure to alcohol have resulted in colossal damage, not comparable to the damage from all known drugs combined.

The effect of alcohol on the human brain

The use of alcohol to affect the brain began at the dawn of civilization. The addiction, legalization and popularization of alcohol consumption has become a great tragedy for humanity. Having fun, raising your mood with new doses of cocktails and strong drinks, a person does not think that lack of coordination, slurred language, memory loss and aggression are the results of the negative impact of alcohol on the body.

About 20% of alcohol is absorbed by the stomach, the rest enters the small intestine. This leads to the fact that strong drinks “go to your head” faster, and if you eat heavily before a feast, intoxication will not occur so quickly. As soon as the absorption of alcohol begins, it is instantly distributed throughout the body through the human circulatory system.

A decrease in the level of neurotransmitters (substances responsible for transmitting impulses from neurons to muscle tissue) leads to a deterioration in reactions and impaired coordination. Moreover, changes in the balance of neurotransmitters can lead to stimulation of brain activity, or vice versa – to suppress it. As a result of taking it “on the chest”, some people become calm and may even feel sleepy, some show aggression, lose common sense, and behave inappropriately to the situation.

Another effect was discovered in 1961 by American scientists. They discovered that a drunk person has a huge number of microthrombi, consisting of hundreds and thousands of blood cells, in the blood. This phenomenon is called "bunches of grapes." The reason for this phenomenon is the presence of alcohol in the blood. By drinking beer, vodka, wine, and after absorption into the blood, the blood thins, it increases its fluidity, which leads to changes in cell membranes in neurons.

The next stage is dehydration, paradoxically, but it is not possible to compensate for the loss of fluid by additional consumption of water, again due to the aggregation (sticking together) of red blood cells. The body begins to show the first signs of fluid loss.

Oxygen starvation is the euphoric effect for which some people love to “step on a traffic jam.” A dehydrated body and capillaries clogged with large plaques disrupt the oxygen supply to the cerebral cortex. This leads to suppression of self-control, confuses logical thinking, reduces intellectual abilities significantly, and in some cases, can even lead to loss of consciousness.

Hangover syndrome. You have to pay for everything; in the case of drinking alcohol, this payment is acidification of the blood. Naturally, a hangover is a temporary phenomenon, but depending on the scale of the celebration, there may be prolonged and painful cramps, active sweating, headaches, temporary loss of coordination, and memory loss.

Do you know why it is so important for alcoholics to get over their hangover? As a result of the regular influence of alcohol on the brain, ischemic stroke occurs. It occurs due to the fact that the blood does not carry oxygen to the cerebral cortex. The use of a new dose of poison increases the heartbeat, increases blood fluidity, and only under such conditions is the supply of neurons partially resumed. Partial plaques in the blood do not have time to be eliminated, and the pressure on the walls of the capillaries increases. This situation ends with the rupture of blood vessels, which becomes the cause of a stroke or heart attack.

What parts of the brain are damaged?

Occipital part of the brain. The result is poor coordination when walking, frequent falls, injuries, one of the reasons for such a high mortality rate from the effects of alcohol.
The centers responsible for common sense, decency, and moral behavior are blocked. The result is immoral behavior, an increase in the crime rate while intoxicated, and suicides.
The mechanism for recording and reproducing memory is disrupted. The result is memory lapses and fragmentary memories.

Do not forget about psychological deviations, such as “delirium tremens”, the appearance of manias and phobias, chronic alcoholism, and aggression. Alcohol has been consumed by humans since time immemorial and is one of the most popular forms of “relaxation,” but it is worth understanding the seriousness of the consequences. If you cannot give up alcohol completely, reduce the amount you drink and watch for a decrease in its negative effects:

Do not exceed doses of more than 50 ml of alcohol;
Drink more water, eat more food;
Do not drive or drive in dangerous conditions;
Try to limit yourself in behavior, control your condition during the feast;
Do not drink cheap strong alcohol;
Do not mix medications, drugs and alcohol.

Drinking alcohol is very similar to a bomb exploding in the body. Absolutely all organs are completely damaged due to influence at the cellular level.

The effect on the human brain has long been proven and comprehensively studied. However, as numerous studies show, in each alcoholic, organic brain damage manifests itself with varying degrees of severity. Some people develop extremely serious problems, while others who drink do not suffer from such problems. But, be that as it may, under any circumstances, the effect of alcohol on the human brain remains purely negative.

The mechanism of the effect of alcohol on the human brain

Almost all organs of the human body are exposed to the negative effects of alcoholic beverages. But it is the brain that suffers the most. The alcohol contained in any alcoholic beverage travels very quickly through the bloodstream to the brain. Under its influence, intense destructive processes begin.

Even after drinking a small amount of alcohol, blood “thinning” is observed. Fluidity increases, red blood cells become more mobile, and aggregation decreases. When alcohol gets into nerve cells and brain cells, the normal structure of their membranes is disrupted.

By increasing the dose of alcohol, a person causes enormous harm to his body. The blood becomes dehydrated and thickens. This occurs against the background of suppression of antidiuretic hormone. The parallel use of non-alcoholic liquids can compensate to some extent for the damage, but the amount of water in the body will not increase from this.

At the same time, ethanol - the main component of any alcoholic beverage - is an excellent solvent. Due to these properties, it can dissolve the membranes of erythrocytes - one of the most important cells in human blood. Blood cells stick together, resulting in thrombosis. Under normal conditions, red blood cells have a negative charge, which allows them to repel each other. Under the influence of alcohol, the thin protective layer of cells is destroyed, the charge is disturbed and the red blood cells stick together.

As a result, stuck together cells clog the capillaries, and this already leads to oxygen starvation and tissue dehydration. It is against the background of such changes that a feeling of euphoria familiar to every drinking person appears, often accompanied by a decrease in the ability to think logically.

Almost everyone who has drunk alcohol at least once in their life has encountered such an unpleasant condition as a hangover. Here, too, there is very strong aggregation (sticking together). A hangover is inevitably accompanied by a process of blood acidification, leading to a decrease in the negative charge of red blood cells and their clumping. Additionally, blood thickening and dehydration are noted. If a person drinks alcohol rarely, then it does not cause him any significant harm. However, those who drink regularly and in very large doses develop extremely serious brain diseases.

What are the consequences of drinking alcohol?

The harmful effects of alcohol on the human brain can be very diverse. It was previously noted that blood clots form under the influence of alcohol. At the same time, alcohol leads to vasodilation and a decrease in the intensity of red blood cell aggregation. Here everything largely depends on the individual characteristics of the alcoholic’s body. However, there is nothing good about this. Against the background of brain bleeding, ischemic stroke may occur, which is an extremely serious disease.

There is another side to the coin. When drinking alcohol, not only does the blood thin, but also the heart rate increases. As a result, blood begins to flow at a much higher speed. It can be compared to a pipeline through which water was released under very high pressure. New pipes usually pass this test, but old ones can behave unpredictably. Especially considering the fact that red blood cells “stick together” due to alcohol and create “congestion.” As a result, the pressure in the vessel increases, to the point that it bursts. The space around fills with blood and a stroke or heart attack occurs.

Under the influence of alcoholic beverages, various dysfunctions of the cerebral cortex appear, which is why alcohol intoxication occurs. At the same time they suffer:

Occipital part of the brain. It controls the vestibular apparatus. It is because of this that drunk people have impaired normal coordination of movements.

The so-called “moral center”. Drunkards change their understanding of morality, ethics and rules of behavior. Even when drinking a small dose of alcohol, the feeling of shame is dulled and the person becomes more relaxed. What can we say about alcoholics who drink a lot and regularly.

The part of the brain responsible for memory and memories. How many times have you heard from other people that they do not remember the events surrounding yesterday's drinking session? Or maybe you noticed this in yourself? All these are consequences of the negative effects of alcohol on the brain.

Against the background of alcoholism, the normal functioning of the brain centers slows down and is disrupted; memory and attention suffer greatly. These changes result in profound changes in the character and overall psyche of a person. There is a gradual destruction of normal thought processes, a radical change in personality occurs, and it begins to degrade. If you do not stop drinking in time, the harmful effects of alcohol on the brain can be so strong that the degradation is irreversible.

With an average degree of intoxication, which is characterized by an alcohol concentration of 0.2%, a person experiences impaired coordination of movements and speech. With an alcohol concentration of 0.4%, the drunkard’s state is already close to comatose. An increase in alcohol content to 0.6-0.7% leads to respiratory arrest and death in most people.

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

The negative effect of alcohol on the human brain can be proven without any medical research. The legs become tangled, the reaction becomes slow, incoherent speech and memory loss appear - all this is a clear confirmation of the harmful effects of alcoholic beverages. For people who are not alcoholics, all this goes away quite quickly; you just need to stop drinking alcohol and sober up. If alcohol is consumed frequently and in large quantities, its harmful effect on the brain remains even long after the immediate effect of ethanol has ended.

That is, alcohol abuse initially lays the foundation for negative, long-term, consequences for the human body as a whole and its brain in particular. The harm of alcoholic beverages manifests itself, ranging from simple short-term memory loss to fatal diseases. The results of recent medical research and qualified tests confirm that even with moderate alcohol consumption, very serious changes occur in the human brain.

The degree of influence of ethanol on brain cells depends on a number of factors, namely:

The amount of alcohol consumed and the frequency of its use.

The age at which the alcoholic began drinking and the length of the period during which he drank alcohol on a regular basis.

The age of the drunkard, his gender, education, hereditary predisposition to alcoholism. It has been observed that people whose close relatives abused alcohol are more at risk of developing alcoholism.

Attitude to alcoholic beverages on the part of a person’s mother during her pregnancy. It has been established that prenatal alcohol poisoning significantly increases the likelihood of developing alcoholism.

General health status.

As a result of the harmful effects of alcohol on the human brain, many different diseases develop. Special attention should be paid to such a problem as alcoholism among women. The characteristics of the body of representatives of the fairer sex are such that alcohol causes them significantly more harm. More on all this later.

Problems with memory and consciousness

Even after drinking a small amount of alcohol, a person may experience memory problems. And the more he drinks, the harder and longer these failures will be. The harmful effect of alcohol on the human brain is also manifested in the fact that in a state of intoxication, the mind becomes clouded, and the drunkard becomes unable to fully account for his actions. The reaction to the environment becomes inadequate and biased. In some situations, a person is unable to normally perceive the actions and speech of other people, which becomes the most common cause of fights while intoxicated.

It has been established that short-term lapses in consciousness due to alcohol consumption occur much more often than previously thought by medicine. Moreover, this effect does not depend on the person’s age or the presence of symptoms of alcoholism. A large-scale study was conducted to determine the harm of alcoholic beverages associated with short-term clouding of reason. More than 700 young people, students of higher educational institutions, were asked only one question: “Has it ever happened to you that in the morning you could not remember the events of yesterday’s drinking?” More than half of those surveyed answered in the affirmative. Some even admitted that, under the influence of alcohol, they committed actions that they would never have agreed to if they were sober, and in the morning, analyzing the events that took place, they felt a huge sense of shame. Some even developed depression, which, by the way, is also one of the manifestations of the harmful effects of alcohol on the human brain.

As for the older audience of respondents, its representatives also reported short-term memory lapses. Such disorders were observed in representatives of both sexes, although according to statistics, men drink alcohol more often than women, and in much larger quantities. Thus, we can conclude that alcohol is more harmful for women than for men. In a state of intoxication, women are much more likely to lose control of themselves and, after the effects of alcohol wear off, cannot remember the events that took place. All this is caused by different mechanisms for the absorption of ethanol by female and male organisms. When drinking alcoholic beverages in equal quantities, a woman is more likely to forget what happened than a man.

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

Representatives of the fairer sex are much more difficult to tolerate the effects of alcohol. Numerous clinical studies have found that female alcoholics develop heart disease, cirrhosis, problems with the nervous system and other disorders resulting from alcohol abuse much faster than men.

Alcohol becomes especially dangerous during pregnancy. Because of it, not only the woman’s body suffers, but also the developing fetus. In the future, the child may develop serious brain diseases. In the most difficult situations, the so-called fetal alcohol syndrome. This is a complex of symptoms that appear in children due to their mother's alcohol abuse during pregnancy. Such children often develop defects of external organs, they develop and grow more slowly compared to their healthy peers. In some situations, there is an increase in the size of the brain, but there are noticeably fewer brain cells than in healthy children. Impaired function of neuronal cells in the brain in children with this syndrome leads to a variety of behavioral abnormalities and cognitive impairment.

What brain diseases does alcohol cause?

Under the influence of alcohol, many brain diseases develop, primarily associated with 2 factors of the effect of ethanol on the body:

Alcohol is characterized by a neurotoxic effect, i.e. under its influence, the death of cells in the cerebral cortex occurs.

Against the background of alcoholism, there is a deficiency of vitamin B1, the deficiency of which leads to disruption of basic brain functions.

With prolonged drinking, the factors mentioned above lead to a severe organic brain disease known as alcoholic encephalopathy. Characteristic symptoms of this disease are emotional instability, memory loss, apathy and indifference, and general malaise. Signs of encephalopathy are confirmation of the transition of clinical alcoholism to its final stage.

Korsakoff's disease is one of the most severe brain diseases that develops against the background of alcohol abuse. It is characterized by the simultaneous presence in the patient of alcoholic encephalopathy, accompanied by dementia and severe memory problems, and polyneuritis. Alcoholics with this disease do not orient themselves in time at all, they cannot determine not only the day, but also the year, and sometimes the season, they are incapable of basic arithmetic calculations, it is difficult for them to move, and the muscles of the limbs atrophy. As a result, the alcoholic becomes severely disabled, unable to live without outside care.

Quite often, alcoholics develop another very serious disease - alcoholic epilepsy. With alcoholic epilepsy, in contrast to the true form of the disease, seizures appear only in a hangover state. If a person stops drinking, they do not recur. However, once it appears, such an attack can easily occur with any hangover in the future. If seizures are repeated, the person will gradually develop dementia. Alcoholic epileptic seizures usually begin suddenly and are accompanied by loss of consciousness. That is why alcoholics are categorically not recommended to climb to heights, relax on bodies of water, drive vehicles, or work with various types of moving mechanisms, even in a state of slight hangover.

The brain is directly connected to the human nervous system, so the negative effects of alcohol are reflected here too. In particular, many problems arise in patients with a disorder of the autonomic nervous system. These are very severe attacks, which are characterized by increased heart rate, a feeling of suffocation, increased blood pressure, various strange sensations, a feeling of fear, depression, etc.

Alcoholics inevitably develop a variety of mental illnesses. At the same time, deviations of varying degrees of severity are found in each addict. In mild cases, everything is usually limited to general neurotic disorders, which include the following symptoms:

Sleep problems.

Fatigue, feeling of general malaise.

Mood changes, irritability.

Alcoholics experience negative personality changes. Their range of interests narrows literally to drunkenness, they become deceitful and irresponsible. Over time, changes in the drunkard's personality will only progress, in some cases reaching complete degradation. Alcoholic homeless people at the station are a prime example of such changes.

Severe mental illnesses of alcohol origin include a variety of psychoses. Most often this is:

Delirium tremens.

Delirium of jealousy developing against the background of alcoholism.

Alcohol paranoia.

Alcoholic hallucinosis.

As for alcoholic delusions of jealousy, in its case everything becomes clear from the name. As a rule, this is a chronic disorder that remains strong for many years, almost throughout life. At best, emotional intensity decreases only towards retirement age. Both the alcoholic himself and the object of his jealousy suffer from this disorder. You can forget about a normal life with a person. These are constant showdowns, reproaches and threats, assault and other “charms”.

An equally common mental illness of alcoholic origin is the so-called. delirium tremens. The disease is not fun at all, although it has become the hero of many jokes. The more scientific name is delirium delirium. Occurs in alcoholics who suddenly stop drinking. This is exactly the case when the statement that you cannot suddenly stop drinking turns out to be correct. In a state of delirium tremens, an alcoholic is dangerous to himself and the people around him. He needs urgent hospitalization and comprehensive treatment.

No less common types of acute psychoses that develop in alcoholics are paranoia and hallucinosis. They have some similar features with delirium tremens; for example, they also begin to develop with a sharp refusal of alcohol, but are characterized by less pronounced stupefactions. Patients begin to experience auditory hallucinations and begin to hear various “voices.” The alcoholic believes in the reality of the voices and begins to look for their source, while experiencing confusion and bewilderment. Hallucinations can have a wide variety of contents. Menacing voices often appear, because of which, over time, the patient develops very strong fear. The consequences can be unpredictable. The patient requires mandatory hospitalization and qualified treatment.

It has been proven that there is not a single organ or system in the human body that is not susceptible to the harmful effects of alcohol. But the brain, as studies show, suffers the most. Alcoholism is also dangerous because many addicts simply do not realize their problem. They create a feeling of illusory well-being. If timely measures are not taken, the consequences will be unpredictable. Therefore, if you already drink alcohol, do it in moderation, be sure to monitor the condition of people close to you and try to prevent them from becoming alcoholics. Be healthy!

The alcohol lobby is doing its job. And there are people who believe in this...

You can often hear the statement that alcohol in small doses is beneficial, it helps dilate blood vessels and improves blood circulation. Research on the effect of alcohol on the human brain has been ongoing for a long time, comparing the blood vessels, heart and brain of an alcoholic with the organs of a non-drinker. Studies have found that ethanol has harmful and often irreversible effects on the brain.

It has been established that ethyl alcohol affects the human nervous system and brain in 3 stages:

at the first stage there is a feeling of euphoria or aggression;
at the second stage, the death of millions of neurons and poisoning of the body occurs;
on the third, degradation of the central nervous system and brain occurs. It is very difficult to restore full brain function after this stage. Often a person permanently loses some abilities.

Euphoria stage

Any alcoholic drink - beer, wine, vodka, cognac, brandy, rum - contains ethyl alcohol. Once in the stomach, it is partially broken down by the enzyme alcohol dehydrogenase; the remaining ethanol is quickly absorbed into the blood and distributed through the bloodstream throughout the body. The liver takes the first hit. It produces a large number of enzymes called acetal dehydrogenase, which neutralize some of the toxins to acetic acid, but the remaining alcohol continues to travel through the circulatory system. Ethyl alcohol is primarily absorbed in the reproductive and nervous systems.

Under the influence of ethanol, the blood vessels of the brain dilate. The rush of blood has a stimulating effect on all brain centers, the medial forebrain bundle or pleasure center is especially sensitive. As a result, the production of endorphins, the hormones of happiness, is stimulated, so the drinker experiences a feeling of euphoria. Depending on individual physiological and mental characteristics, stimulation of this group of neurons causes aggression in some people.

The expansion of blood vessels and their filling with blood at the first stage causes a short-term decrease in pressure, so doctors do not prohibit alcohol in small doses for hypertensive patients. But vasodilation lasts an average of 30 minutes, and the complete breakdown of ethyl alcohol into safe components in the human body occurs at an average rate of 30 grams per hour, so the second stage soon begins - the toxic stage, when the harmful effects of alcohol on the human brain are noted.

Stage of poisoning

Enzymes continue to slowly break down ethanol, so alcohol continues to poison the body (the breakdown products also have toxic effects). After dilating the blood vessels, it begins to affect the blood. Ethyl alcohol dissolves the membranes of red blood cells, causing them to stick together, forming clots, a process called “sludge.” When blood sludges, the resulting clots clog the capillaries, including those in the brain. Unable to withstand the blood pressure, such capillaries burst, and many microscopic hemorrhages form in the brain.

In addition, “spoiled” blood can no longer fully perform its functions and sufficiently fill tissues with oxygen and nutrients. This is especially detrimental to the brain, since oxygen starvation leads to massive death of nerve cells. Alcohol literally destroys the brain.

Dead cells are excreted from the body in the urine after about one day. Brain recovery occurs very slowly, this explains the inhibition and poor reaction of a person, a decrease in his intelligence over the course of 2 weeks after taking a large dose of alcohol.

The harmful effect of alcohol on the brain is accompanied by a malfunction of the entire central nervous system. The subcortical centers and frontal lobes perceive impulses chaotically, which causes changes in behavior - drunk people cease to control their actions: euphoria gives way to apathy (the emotional background is reduced) or aggression, consciousness is confused, thoughts lose clarity, reflexes slow down, the tongue becomes slurred.
Already at this stage, the harm of alcohol is strongly pronounced, but ethyl alcohol does not stop its effect. It is absorbed into all parts of the brain - the hypothalamus, thalamus, cerebellum, midbrain and medulla oblongata, disrupting their functions.

Fact! With large doses of alcohol, blood sludge becomes irreversible, which causes strokes and heart attacks.

Degradation stage

Damage to brain cells, death of millions of neurons, and massive hemorrhages cannot pass without leaving a trace for a person. With prolonged drinking of alcohol in large quantities, brain cells die faster than they are restored. As a result, there are fewer and fewer of them, and the alcoholic’s brain seems to dry out. Autopsies confirm that the brain of a chronic alcoholic is smaller in size and weight compared to the brain of a healthy person. Histological studies have revealed that serious destructive changes occur in the brain of a drinker, which entail an accelerated transmission of nerve impulses. In life it looks like overexcitement, nervousness, and aggressiveness. The described mechanism of action of alcohol includes 3 stages of influence on the human body in general and the brain in particular.

But sometimes events develop in a different way: a single intake of a large amount of alcohol does not give the body time to cope with the toxins that are released at the first stage of the breakdown of ethanol; the poison damages the medulla oblongata, which is responsible for respiratory function. This is very dangerous, since the destruction of this section can cause respiratory spasms, coma and death. However, too much alcohol often causes vomiting. In this case, vomiting is a protective reaction of the body that allows you to quickly remove excess ethanol from the body.

Effects of alcohol consumption on the brain

This is what happens to the brain when drinking alcohol:

Drinking alcohol in any quantity leads to the death of brain cells - neurons, and the number of dead cells is directly proportional to the alcohol consumed.
Blood sludge (clumping of red blood cells) causes capillary thrombosis, which causes numerous small hemorrhages in the brain or stroke.
Over time, the appearance of the organ changes: the brain decreases in size, its convolutions become smoother.

Intense brain poisoning with alcohol leads to the following consequences:

coordination of movements is impaired;
adequate assessment of reality decreases;
memory and intelligence are impaired;
thought processes slow down;
vision and hearing become dull;
difficulties arise in navigating the terrain;
the person is unable to cope with outbursts of anger;
heart rate increases, dizziness appears;
sensitivity to pain is lost.

In case of severe poisoning, alcohol acts as a hallucinogen: a person begins to see unreal images and non-existent objects.

After 3-4 years of constant drinking, the effect of alcohol on the brain causes:

difficulties even with simple mental work;
the thought process becomes extremely limited;
critical thinking decreases;
the person becomes extremely unstable emotionally: attacks of irritation are replaced by apathy, alcoholic depression may develop;
As a result of the fact that alcohol kills brain cells, diseases such as dementia, dementia, and Alzheimer's disease develop.

The process of brain restoration is possible, although it is extremely slow.

Prevention and recovery of the brain after alcohol

After giving up alcohol, returning to a normal life is very difficult, but possible. The first step is to ensure that ethanol no longer enters the body, and over time it will be cleared of harmful substances. To quickly cleanse the body, it is recommended to detoxify it with the help of medications. Next, you need to lead a healthy lifestyle, take a course of vitamins, and, if possible, undergo a course of sanatorium treatment. This will help the body poisoned by alcohol to regain strength and health.

After quitting alcohol, all organs recover differently, but the nervous system and brain return to life the slowest. To fully restore their functions, it will take several years after completely stopping drinking alcohol. Scientists, studying the effect of alcohol on the brain, come to the conclusion that it will not be possible to completely return 100% to their former capabilities, and even after 10 years, it will be possible to recognize someone who at one time abused alcohol by their characteristic behavior and reduced intelligence. But this only applies to chronic alcoholics. If a person takes moderate doses of alcohol, then brain function will be only slightly impaired and no recovery is required.

Safe doses of alcohol depend on the individual capabilities of the body. Average levels of permitted alcoholic drinks per day for a man aged 30 to 40 years weighing 75 kg:

beer - 0.5 liters,
fortified wine - 200 grams,
vodka - 50 grams.

For women aged 25 to 35 years weighing 70 kg per day, without harm to health, you can drink:

beer - 0.3 liters,
fortified wine - 150 grams,
vodka - 30 grams.

At the same time, at least 3 days a week must be completely “sober”.

The destructive process of alcohol’s effect on the brain and central nervous system can lead to irreversible consequences and complete personality degradation. You can return to a full and healthy life after completely giving up alcohol, and the brain is fully restored within several years.
