Mankind has endured the pangs of addiction arising out of consuming alcohol since ages. Alcohol is one of the oldest drugs familiar to man the physiological methods through which it triggers intoxication and chasing it have not yet been confirmed. (Researchers Study Mechanism of Alcohol's Effects -- One Cell at a Time) Alcohol abuse and alcoholism happen irrespective of gender, race and ethnicity. About 14 million people in the United States -- in 13 adults -- alcohol or have alcohol addiction. On the average nevertheless, men compared to women have affinity for alcohol or possess alcohol related problems. Moreover, it is most prominent among the young adults in the 18-29 age brackets and least among the older adults who are 65 years and more than that. Further, people who begin drinking at an early age for instance 14 years or younger -- increase the possibilities that they will develop alcohol related problems at some stage of their lives. (Alcohol Abuse) Precisely in the manner in which alcohol impairs the brain and the possibility of overturning the influence of maximum drinking on the brain continue to be widely discussed subjects in alcohol research currently. (Researchers Study Mechanism of Alcohol's Effects -- One Cell at a Time) In this paper we shall understand as to why it is necessary to study the effects of alcohol on brain and behavior.
The need to research the impact the influence of alcohol on the brain and behavior lie exactly on its sweeping effects on the human population. With alcohol affecting the brain, some of the damages are diagnosed following only one or two drinks and rapidly resolves when he stops drinking. Extreme drinking might have wide-ranging and sweeping impacts on the brain, which might range from mere "gaps" in memory to long-term and incapacitating state that need safekeeping care for the entire life. (Alcohol's Damaging effects on the Brain) Long-term drinking might lead to irreversible impairment to the brain, severe emotional disarray and alcohol intoxication. One of the lasting impacts of alcohol on the brain is to lower the quantity of brain tissue and to swell the size of the ventricles in its place.
Extensive heavy drinking might result in decrease in the volume of the brain and the shortage of fibers which transmit information among the brain cells. Another way through which alcohol consumption impacts the brain is denying it of food materials like vitamins. The cause behind this is that heavy drinkers frequently overlook their diet, resulting in shortage of vitamins. Thiamine, one of the 'B' vitamins is most usually not found in the daily food and can be responsible for severe mental disorder. The work of alcohol is that it behaves as a sedative on the Central Nervous System, subduing the nerve cells inside the brain, numbing, changing their capability to react. Heavy consumption results in sleep, anesthesia, and failure of the respiratory organs, coma and death. (Alcohol - Effects on the Body) Plus, even reasonable drinking results in short-term damage, as revealed through wide-ranging research on the impact of drunken driving. (Alcohol's Damaging effects on the Brain)
Huge amount of alcohol consumption done in one go and in empty stomach, have every chances of affecting a blackout, or a time span in which the drunken person will fail to recollect important finer points of information or even the entire sequence of events. Blackouts appear to be more widespread among those who drink on social occasions compared to what have been understood in the past and must be taken as a possible impact of severe intoxication irrespective of age or in case the drinker is medically dependent on alcohol. Women have increased chance of susceptible compared to men and in respect of several of the clinical effects of alcohol consumption. Computerized tomography through the use of images, contrasted brain shrinkage, a frequent pointer to brain damage, in case of alcoholic men and women and stated that male as well as female alcoholics revealed considerably higher brain shrinkage compared to control subjects.
Researches reveal that men as well as women possess identical difficulties in learning and memory due to excessive drinking habits. The dissimilarity remains that alcoholic women stated that they had consumed heavily for just half the period as alcoholic men in these studies. This shows that the brains of women, similar to other organs, have increased susceptibility to impairment due to alcohol compared to men's. Researches contrasting men and women's reaction to brain impairment due to alcohol, nevertheless, have not been convincing. These show the need to continue studying the effects on brain and behavioral changes. Drinking while pregnant can result in varied physical, learning, and behavioral impacts in the fetal brain which is slowly developing, the most severe of which is a group of symptoms called as Fetal Alcohol Syndrome of FAS. Children affected with FAS might have different features in the facial region. FAS infants are also prominently smaller in size compared to the average. Their brains might have less overall mass. Plus, they might have lesser quantities of brain cells or fewer neurons which work properly, resulting to long-term impairment in learning and behavior. (Alcohol's Damaging effects on the Brain)
The adolescent brain is meant for learning; nevertheless the same flexibility which is responsible for automation of the nervous system also makes it susceptible to the detrimental effects of alcohol. Alcohol, still, can upset the adolescent brain's capability to learn life skills. Therefore, extensive alcohol consumption during this stage of life can get the victim into hordes of difficulty through behavior like risk taking and drunken driving, but it can even render the brain less capable to learn vital proficiencies in life which can aid one avert problems in later life as an adult. The neurochemical, cellular, synaptic and structural build up of the adolescent brain renders it more helpless compared to the adult brain to distraction of activities like overindulged drinking. Studies has recognized delicate but vital changes happening inside the adolescent brain with Alcohol Use Disorder or AUD, leading to lessened capability in solving problem, verbal and non-verbal recall, visuospatial competence, and functional memory. Alcohol caused damage to memory; like "blackouts" are especially normal among the young drinkers and the reason behind might partly be because of snapped neural flexibility in the hippocampus that is responsible to the core in the development of autobiographical memories.

Research professionals have revealed that the brains of alcoholics are tinier in size and brain tissue loss is found to be more than his non-drinker counterpart. Familiar as the premature aging hypothesis, the effects of alcohol is known to "speed up normal aging" process and the make the young drinkers appear more in age than they actually are. This type of ageing on account of alcohol enables the non-drinkers of the same age, quick fire and agile in cognitive abilities. (Alcohol and its effects) However, the adolescent brain continue to be a work in progress, stated by Peter M. Monti, seminar organizer and Professor of medical science and Director of the Centre for Alcohol and Addiction Studies at Brown University, which reveals the urgency to pursue with the research. Urgency is required to arrive at trans-disciplinary and translational science to tolerate on the influences of alcohol on the adolescent brain.

Consumption of alcohol puts a severe effect on the behavioral levels of persons as well. After consuming a few drinks, the speed at which mental faculties work slows down. Our potential to pay attention on a particular work or to share our attention between two tasks lessens. At this stage consuming a few more drinks can damage your capability to accomplish tasks which generally need little thinking ability or expertise. Feelings of tension, violence and antagonistic behavior, or gloominess can go up due to drinking. (How Alcohol Affects Your Behavior) Consumption of alcohol induces mild ecstasy and loss of self-consciousness since alcohol damages areas of the brain responsible for behavior and emotions. Alcohol damages power of decision, memory, attentiveness and dexterity; as also causing tremendous mood swings and emotional eruptions. Due to alcohol ability to take judgment suffers and can augment our readiness to take risks. (Alcohol - Effects on the Body)
Alcohol is understood to damage a person's capability to control their behavior. Drinkers might at times exhibit silly, wrong or damaging behavior which they might refrain from when they are sober, according to Muriel Vogel-Sprott, professor of psychology at the University of Waterloo. Alcohol has the powers to weaken cognitive control of response reticence and that susceptibility to these non-reticence changes among persons. Apart from this, a lot of personal characteristics are existent-like reacting to impulses, symptoms of attention deficit disorders, and the potential to remember the appropriate information required to steer behavior which are associated with lower reticence under the influence of alcohol. It appears that alcohol lowers the capability to prevent some activities. This is vital since everybody among us is required…
