Alcohol and Your Brain


The brain is the control center of the body. You are allowed to run and play, learn new facts and ideas, and you can feel a range of emotions. The brain can process information, hearing the smell, taste, and feeling, the five senses – seeing through the collection. Major life processes such as breathing and maintaining a regular heartbeat, even if you listen to sleep, make sure you also maintain a part of the brain.

The brain is part of the body system called the central nervous system or CNS. The central nervous system consists of a billion number of brain and spinal cord, nerve cells, or neurons. Peripheral nervous system, including neural cells, form a network of communicating information about the neck and arms, torso, legs, muscle and internal organs.

What happens after surgery CNS is? Despite all body systems can feel the effects of alcohol, SNC is particularly sensitive. Alcohol goes directly to nerve cells, blood – because it can pass through the brain barrier. Once the alcohol is in contact with the cells, which are changed as a result of a change in behavior.

The nervous system and brain Let’s learn more about the effects of alcohol.

Central Nervous System (CNS)

Central Nervous System

The central nervous system is responsible for taking the information through the senses, motor skills, thinking, understanding and reasoning. The system also controls emotions. The central nervous system includes nerves from the brain, spinal cord, and it. The most important part of the central nervous system is protected by the bones. The skull protects the brain and spine protects the spinal cord.

Alcohol is a central nervous system depressant. That means that alcohol causes nerve cells in the brain will slow are less excited. Are you surprised? Because people booked less frequently drink alcohol more animations that experience “”pick-me-up for.”” Because increases the level of detail increases in the first animation region is affected by the amount of alcohol, and are not related to behavioral inhibition, which could lead to more social. But the brain is slow there are many signs. Here are a few:

  • changed speech
  • nebulous
  • slow response time
  • boring hearing
  • vision problems
  • Muscle weakness
  • memory fog

Exactly how much the speed of brain activity depends on a variety of factors it slows. Other drugs, how much and how quickly a person drinks, as if shot like marijuana is significant. Its size, weight and sex acts with their genes. Alcohol abuse is when it runs in the family, you are, the greater the risk is too much trouble.

The Brain

The Brain

The brain consists of more than 100 billion nerve cells. Respectively, the tens of thousands of connections. Changes in damage alcohol, or possibly still developing in the development of the adolescent brain, can kill nerve cells.

The blood-brain barrier because it can pass through alcohol can penetrate the brain. means that you can move to the brain cells, blood circulation. Because it can directly touch the brain cells, sometimes when brain cells die, they used to think that you can not go back, scientists use ” alcohol kills brain cells,” but the new study says this does not It may be true. Now scientists believe that in some areas of the brain, cell regeneration, or to return.

Another idea for change in the brain is the time it takes to develop. The researchers developed will be used to think that occurred during the first years of life. The new study, however, showed that significant changes are taking place in the twenty years of puberty and people. For example, to help youth part of the brain, which can control the emotional decisions and control their impulses they are not yet formed. Many features of adolescence, such as changing these feelings, in part, can result in brain development.

This summary is what the role of different parts of the brain, alcohol provides information that affects its function.

Striatum (striatum) of brainpartsVentral and prefrontal cortex: This section is to configure the connections in the brain’s reward system and control impulsive behavior. The young people drinking too much alcohol can affect this connection has not yet been developed to complete. As a result, young people can be impulsive probably not in normal circumstances. Striatum is also a part of the brain receives the first impact, causing less protection operation is released.

Hippocampus: This is part of the brain stores memory. However, to mature in adolescence. Even small amounts of alcohol are not teenagers, or you can forget what they learned while drinking.

Cerebellum: This section acts as the primary motor cortex to control the dynamic balance and complex motor skills. The drinking motor function can reduce the slow response time. For example, can not stand or walk in a straight line when the person is drunk.
Frontal Lobe: This section controls judgment, behavior, and emotion. Alcohol, crying, fighting, or otherwise can affect feelings that lead to a desire to close.

Reticular activating system: This part of the midbrain controls waking from sleep, that is. Alcohol can cause the system to depress the people stunned.

Water quality is a part of the back of the brain, which controls heart rate, breathing, and other functions. While drinking, which can slow endanger the lives of people or not at all.

Neurons: These are nerve cells. Enter your cell damage, and this reaches the alcohol, or enough to kill a high level.

Vascular: alcohol is the vasodilator and expanded. At higher levels, it was worse conditions such as a migraine; it can constrict blood vessels and increase blood pressure.

Alcohol Can Be Dangerous

You can immediately see the effects of alcohol on all parts of the brain and nervous system. Other parts of the brain to “”shut down”” of alcohol abuse, can not participate in the good deeds for young people. Here are some activities that young people can find “”under the influence”” in their day to include:

Bad decision. Since immature prefrontal cortex, alcohol can impair the ability of young people to the weight of reason and choice. Fun or it can be a teenager simply because something instead of feeling good.
Generally, they will not be willing to take risks. Since the connection between the prefrontal cortex and the ventral side is not yet mature, alcohol can affect this connection. As a result, young people can do this kind of impulsive sex is not drinking and driving, or protection. All these activities can lead to negative consequences.

Interfere with prescription medications. Some young people who take drugs for conditions such as attention deficit disorder (e.g., Ritalin); Bipolar disorder (lithium); Depression (Prozac). It can increase the effectiveness of some of these drugs. For example, it may damage the Ritalin mixed with alcohol on the ability of young people to perform a task that requires total concentration. Amount of judgment thought and lithium mixed alcohol and can have a reduced capacity.

Sometimes, too, people often drink is not too dependent on alcohol may not function properly. In this case, the person has crossed the binging in new areas. Now he suffers from the disease of alcoholism. If a person with addiction, which he or she may also be considered addicted to it.

Why do some people have more alcohol problems than others? From the early onset of drinking it refers to the study of the relationship between alcohol-related problems. There is evidence that young people start drinking earlier and earlier. In 2003, the average age of first use of alcohol is four times was about 14 years, compared to those individuals 17½ 1965 for years before you start to see the liquor possibly 15 years reported having symptoms of alcohol dependence at some point is your life. New research shows that in general a serious drinking problem (including the so-called alcoholic) associated with young middle-aged adults, even during puberty begin to appear much earlier.

He continued his brain to drink a lot of people go on to develop a tolerance for the use or alcohol. This means they need more alcohol to achieve the same effect as before. Throughout the nervous system, what is happening is that alcohol is a cause of nerve cells slows. To compensate, the brain pushes these cells go faster. The brain is used more alcohol pushes nerve cells. Noun eventually pushes the nerve cells that sense the need to drink slowly working properly. They are the reason why some alcoholics long term, even before the start of the day you need to drink.

The highest rate of reported alcohol abuse among adolescence and early youth. The second group has a high ratio defined as having 4-5 drinks for two hours at 12 years of age to participate in binge drinking 17 high school and college students, young teenagers.

New research indicates that heavy drinking may fall teenager can last more than a few of the party. Neuroscientist Susan Tapert, California, the University of San Diego, studied the effects of excessive alcohol consumption on the brain development of young people. Not binge drinkers and comparison of brain MRIs drinkers binge drinking, the information of the protein part of the brain responsible for its rapid found and not so well trained.

After observing these changes, changes in the target issue, Dr. Tapert wanted to know the impact on functionality. She has a different kind of group of tests that measure the ability to perform a specific task. What was particularly interesting about him is that his findings were different for boys and girls. Girls are less performing the test to measure the spatial characteristics such as the ability to copy a difficult puzzle. Boys, on the other hand, tend to perform tasks that require less attention. This is boring, but the type of activities to be carried out. The difference was about 10% which can be converted to a difference between the A or B

Is it these effects are permanent? At this point, researchers do not know. But they continue to study the impact of adolescent heavy drinking, so they will soon have to see the answer.

Alcohol abuse is a problem that can lead to significant health – can affect the ability to learn and perform well. The best way to protect yourself from these problems never wholly starts drinking. It is a foolproof method that works all the time.

How alcohol affects the body

Path alcohol through the body

Alcohol moves through the body in the circulatory system, brain, kidneys, lungs, liver, stomach. As alcohol consumption and absorption, can cause the following cases:


Alcohol can be stimulated if the alcohol content is high enough to pass the sensitive film
Heavy drinkers run a much higher risk of mouth and throat cancer


    • Alcohol can easily pass through the stomach lining, which need not be digested molecules are very small
    • If the stomach is empty, alcohol is delivered directly into the bloodstream
    • If the above is highly food, protein food, especially not leave only slow the rate of alcohol absorption
    • Can be mixed with alcohol, carbonated drinks are alcohol absorption rate
    • Stimulate appetite, increase the flow of gastric juice, because of a small amount of alcohol
    • Due to the large amounts of alcohol can cause as much appetite blunted and malnutrition in the production of gastric juice
    • Excess alcohol from above facilitate the flow of gastric juice, and irritation of the gastric mucosa and ulcer due to the high alcohol content combined
    • It is a sufficiently high concentration of alcohol and gastric juice if the stimulus is increased, the vomiting reflex stimuli are some of the runs as a way to relieve body coating
    • 20% of the alcohol is consumed and absorbed into the bloodstream through the stomach and 80% ( the rest is alcohol) absorbed from the intestine into the bloodstream

Circulatory System

Once in the bloodstream, alcohol is rapidly distributed and uniformly throughout the body
Alcohol is to inflate or cause blood vessels to widen blood:
The large flow of blood on the surface of the skin (flushing)
temporary feeling warm
Reduce heat loss and increased body temperature, fast
Pressure drop


When alcohol reaches the brain, affecting the brain that controls body functions and immediate action
An alcohol concentration (BAC level) of the blood flow, increasing the functionality, and behavioral changes of the body
Impact on specific BAC levels are as follows:
BAC of 0.02% or judgment, self-control, and emotions began to be affected, and the result is greater relaxation and talking excessively
0.06% BAC reaction time adjustments reduce the impact, but both can be very clear
BAC of 0.10% or vision, speech, balance, awareness, and self-control are affected
0.18% BAC significantly affected walking and standing. (Film buttoning walk straight)
BAC 0.20% or memory, intelligence, and damage to the emotional center of the brain, sensory-motor skills are affected; And excited to think clearly, or can not easily be furious
0.30% BAC body was thrown into a complete state of confusion, and no signs: walk normally speech, double vision, hearing impairment, aging and mood swings faster, difficult or impossible to determine the distance
BAC is 0.40% of the brain nervous system, can hardly act inefficiently; This man is unconscious or nearly unconscious; The body can cause uncontrolled urination can barely move they seem frozen or vomiting,
0.50% BAC who have fallen into a coma; Breathing, heart function, blood pressure can be controlled by brain temperature is drastically reduced by low-risk points; Does death can be frequent
Brain For more information about the effects of alcohol.


It means diuretic effect alcohol, which increases urine output
People will urinate more frequently, causing dehydration and thirst


The gaseous alcohol can be absorbed from the lungs into the bloodstream quickly to go there
5% of the alcohol is taken into the body lungs, kidneys, leaf through the skin; The rest is removed from the cross


95% alcohol in the body when the body leaves the oxidation in the liver
Oxide is converted into water and carbon dioxide alcohol
The liver can oxidize about one drink per hour. (This is the only reason for time to calm people down.)
Alcoholic liver damage consumed regularly. Damage caused is as follows:
fatty liver
Alcohol interferes with the function of the liver to break down fat accumulates in the liver
If you stop drinking, the condition usually reverses
Excessive alcohol use is destroying the normal liver tissue replaced by scar tissue.
Cirrhosis liver function and blood flow is diminished
progressive cirrhosis (scarring or cirrhosis)

Alcohol and Health

A low dose of alcohol is both a 80% reduction in risk beverage consumption and reduce the risk of coronary heart disease (20 g alcohol) per day
Risk of heart disease increases two drinks more than a week of daily risk, beyond
To drink, what potential benefits are overwhelmed by the increased risk
