Although alcohol may give you a feeling of elation and aroused senses due to a lessening of inhibitions during the early stages of alcohol intoxication, alcohol is a depressant. It depresses the central nervous system—leading to slowed reactions, slurred speech, and ultimately, to unconsciousness. Alcohol progressively affects different brain areas. Alcohol first affects the part of the brain that controls inhibitions. When people lose their inhibitions, they may talk more, get rowdy, and do foolish things. After several drinks, they may feel “high,” but really, their nervous system is slowing down.
Alcohol acts fast because it is not digested like food. Instead, it moves directly into the bloodstream from the stomach and small

ARE WOMEN MORE VULNERABLE TO ALCOHOL’S EFFECTS ON THE BRAIN?
Women are more vulnerable than men to many of the medical consequences of alcohol use. For example, alcoholic women develop cirrhosis (5), alcohol–induced damage of the heart muscle (i.e., cardiomyopathy) (6), and nerve damage (i.e., peripheral neuropathy) (7) after fewer years of heavy drinking than do alcoholic men. Studies comparing men and women’s sensitivity to alcohol–induced brain damage, however, have not been as conclusive.
Using imaging with computerized tomography, two studies (8,9) compared brain shrinkage, a common indicator of brain damage, in alcoholic men and women and reported that male and female alcoholics both showed significantly greater brain shrinkage than control subjects. Studies also showed that both men and women have similar learning and memory problems as a result of heavy drinking (10). The difference is that alcoholic women reported that they had been drinking excessively for only about half as long as the alcoholic men in these studies. This indicates that women’s brains, like their other organs, are more vulnerable to alcohol–induced damage than men’s (11).
SUMMARY
Alcoholics are not all alike. They experience different degrees of impairment, and the disease has different origins for different people. Consequently, researchers have not found conclusive evidence that any one variable is solely responsible for the brain deficits found in alcoholics. Characterizing what makes
The pathophysiology of alcoholism begins after alcohol the ingestion of alcohol. It is absorbed and unaltered through the stomach and intestines. Next it is distributed throughout the body through the blood and absorbed by all tissues and fluids (Huether, 2012, p. 72). Furthermore, in the liver the alcohol blood content is metabolized into acetaldehyde by the enzymes process of alcohol dehydrogenase (ADH), the microsomal ethanol oxidizing system (MEOS), and catalase (Huether & McCance, 2012). Next, the metabolizing effects the central nervous system (CNS) and exhibits a depressant action. It is first expressed in the subcortical structures of the brain. This has an effect of disorientation of motor skills and intellect. With an increase in blood alcohol concentration, the medullary centers become depressed and as a result affects respiration (Huether & McCance, 2012). In addition, the effects of alcoholism encourage hepatic and gastric changes. The hepatic effect is caused by acetaldehyde, in which, induces inflammation, fatty deposits and enlargement of the liver (Huether & McCance, 2012).
Alcohol impairs judgment, memory, concentration and coordination, as well as inducing extreme mood swings and emotional
Alcohol is a liquid substance that can which when consumed slows down the brain. It also alters the brain to increase the risk of depression and anxiety. When too much alcohol is consumed it can cause memory loss.
As a college student, alcohol is a very real and prevalent temptation. It is a normal occurrence for a Friday night to be filled with friends, a bonfire, and alcohol out on the lake. Unfortunately, not many students know the effects of alcohol on their brain. I took a personal interest in this subject because alcoholism runs deep in my family. I want to know what effects my personal consumption of alcohol have on my brain and how they will affect my life if I continue to drink or choose to stop.
Drinking heavily and binge drinking leads to short-term as well as long-term health consequences in males and females. Both women and men can suffer the short-term
Alcohol can cause alterations in the structure, and the consequences may be evident beyond adolescence. Even though alcohol appears to be a stimulant, really it is a central nervous system depressant, depressing the brains inhibition control center (“too smart to start”). Neuron connectivity is vital to every human. Connectivity can be slowed down by alcohol consumption, which leads the person to think, speak, and move slower (“too smart to start”). Long term effects include memory loss and continuity of poor judgement. The cerebral cortex works with the senses; when the senses are debilitated, information is forgotten and senses do not function properly. The hippocampus regulates a person’s memories. When consuming too much alcohol, or even just one or two drinks, the hippocampus will damage, and a person will struggle remembering minor and large details. Teenagers often gloat over not being able to remember the night before. Even though their night may have been an “awesome blackout” their hippocampus has already been permanently damaged. The person now, can not hold on to knowledge and learn the same as before. The cerebellum controls coordination, thoughts and awareness (“too smart to start”). On most occasions, people have problems with these skills when consuming alcohol. In grade school, D.A.R.E. representatives brought “drunk goggles” to school. Studies show that alcoholism in the cerebellum
Alcohol affects the brain for a short-term– but repeated drinking may have an impact down the road, especially as a person’s brains grow and develop (NIDA, 2016). When a person is under the influence, he or she may feel their bodies having less aware of their surroundings. A person also may feel very relaxed and perform risky behavior, without even realizing. Long- term effects of alcoholism can cause a person to have trouble processing, learning, or a dependence on
After alcohol reaches the brain, it numbs the frontal lobe, which has direct control over the judgment, visual perception and decision making skills. Scientists believe this is what makes alcoholics believe they can conquer any task put before them. After drinking a good number of drinks everyday over a long period of time, many things can happen. Cirrhosis of the liver can occur, which means the liver tissues become hardened. Scientists also report that irreversible brain damage can occur before cirrhosis of the liver is even detected. Also, cancer of the liver, mouth, esophagus as well as lungs and pancreatic cancer often occur as a result of alcoholism. Alcohol also has an affect on the mind as well as the body. Alcoholics often report that they feel inferior to people and believe they can do anything. Many people believe that alcohol acts as a "social lubricant." Increased social pleasures, assertiveness talkativeness and even happiness are all expected by many, when they drink in these situations. Alcohol is said to reduce tension and anxiety. This in turn allows drinkers to feel more relaxed and comfortable in social situations. However, this also encourages the drinker to drink more when under more stress.
That scenario shows only a few of the side effects alcohol can cause to a person. Alcohol creates a disruption regarding the connection of the brain. The brain controls physical and psychological actions. Many people do not think about the possible outcomes that alcohol can cause to themselves. Most american’s drink occasionally and some frequently.
Alcohol is primarily absorbed through the stomach and the small intestines. It is considered a food because it has calories, but does not need to be digested and proceeds directly into the body through the digestive system. After ingestion it is carried through the blood stream and crosses the bloodbrain barrier, at which time impairment begins. A greater amount of ingestion causes greater impairment to the brain, which, in turn, causes a person to have a greater degree of difficulty in functioning. The majority of alcohol in the body is eliminated by the liver. Ninety percent is eliminated through the body, while ten percent is eliminated through
In Jill Dombrauckas’s (2015) report, she discussed that the Pennsylvania DUI Association made a large amount of researches about alcohol’s effect on body systems. In one research, alcohol affects the central nervous system which means when the individual drink alcohol, the messages that are carried to and from the brain and the body’s muscles can be slowed delivery. For example, the incoming signals from the brain, like the painful sensory that will decrease the injury’s awareness. Also the signals from the brain to the muscles will lead the motor skills becoming insensitive.
Alcohol dependence is known to be the most severe form of alcohol abuse. A person becomes so dependent on alcohol consumption that he/she loses sight of all the other important things going on around him/her. Family matters and social responsibilities become secondary worries to his/her primary concern for existence, which is drinking (Stephens, 2007). Nearly fourteen million Americans are somewhat dependent on alcohol. Alcohol dependence is more prominent in men, and young adults ages 18-29 (Stephens, 2007). According to a study done by Saitz “85,000 deaths, along with substantial disability from medical and psychiatric consequences, injuries and “secondhand” effects (ex: motor vehicle crashes) are attributed to the use of alcohol” (Saitz, 2005).
Ethyl alcohol, which is the type of alcohol found in alcoholic drinks, enters the bloodstream through the walls of the gastrointestinal tract, mostly from the walls of the stomach and of the small intestines. Once ethyl alcohol enters the bloodstream, it passes through the brain and bathes the brain cells. This is how alcohol "kill" brain cells and damages the brain. (5) Different levels of alcohol in the blood have different effects on the behavior of a person; however, these effects are not predictable. At low levels, the inhibitory centers are usually suppressed and there is a "false sense of increased confidence and a feeling of well being." The depressing effects of alcohol on the brain may relax a person but equally likely, may make a person irritable, mistrusting, and very sensitive. (3) (4) (5) (6) While feeling relaxed is generally good for a person, it carries negative effects when a person gets in trouble from being overly relaxed. For example, there are cases in which women are raped as a result of being too comfortable with the men they drink with. Studies show that a substantial percentage of victims of violent crimes were intoxicated at the time of their assault (2). Offenders may
Alcoholism is a very serious disease, which can cause illness, death, injuries, schooling problems, family breakups, and crime. It is a proven fact the alcohol kills more people than any other illegal drugs combined. However, alcohol courses freely through American society, from college bars to corporate lunches. In a recent journal article by The Scientist, it is stated, "Technology shows alcohol abuse changes brain's molecular programming and circuitry? (Scientist). Thus revealing that alcohol is a quick fix that will hurt us all in the long run.
Many believe that alcohol affects women much more than it does men. This can sometimes be because men are much bigger than women are but at the same time, men usually metabolize faster when means that their bodies can break down the toxins much quicker. Studies have shown that women are more vulnerable than men are too many of the medical consequences of alcohol use. For example, alcoholic women develop cirrhosis, alcohol induced damage of the heart muscle (i.e., cardiomyopathy), and nerve damage (i.e., peripheral neuropathy) after fewer years of heavy drinking than do alcoholic men (National Institute on Alcohol abuse, 2004). Studies comparing men and women’s sensitivity to alcohol-induced brain damage, however, have not been as conclusive.
