Abstract Over the past 40 years, rigorous examination of brain function, structure, and attending factors through multidisciplinary research has helped identify the substrates of alcohol-related damage in the brain. One main area of this research has focused on the neuropsychological sequelae of alcoholism, which has resulted in the description of a pattern of sparing and impairment that provided an essential understanding of the functional deficits as well as of spared capabilities that could be useful in recovery. These studies have elucidated the component processes of memory, problem solving, and cognitive control, as well as visuospatial, and motor processes and their interactions with cognitive control processes.
Ethyl alcohol ethanol is the active ingredient in all alcoholic drinks. If you take any alcoholic beverage and remove the ingredients that give it taste and colour, you get ethyl alcohol. Remove the water from ethyl alcohol and you get ether.
Ether is an anaesthetic that works on the brain and puts it to sleep. The same symptoms surgical patient experiences under ether are those experienced by a person drinking alcohol.
Alcoholism Alcohol consumption is a learned behaviour- no one likes the taste of alcohol at first. Alcoholics are perceived as being weak people or as having bad habits.
Alcoholism is the disease produced by the repeated misuse of ethyl alcohol. It is a Primary disease: It is a chronic disease: It is a Progressive disease: It is a potentially Fatal disease, if the drinking is not interrupted.
A primary characteristic of an alcoholic is a loss of control- once an alcoholic starts to drink, he or she is not able to predict things or situations in a normal way. There are at leastalcoholics in Australia and 1 person in 10 who drinks at all will become an alcoholic.
Once alcohol is absorbed into the bloodstream, it is rapidly distributed throughout the body. It affects almost every cell, every organ, and every level of human functioning. The most profound early effect is on the central nervous system, where it acts as a sedative, producing relaxation and sense of well-being.
It impairs the intellect, physical abilities and metabolism. When alcohol is taken regularly, in large amounts over many years, permanent physical damage will occur.
This damage is often aggravated by the lack of vitamins because most alcoholics have poor eating habits. Alcohol can also damage the liver, brain and other parts of the nervous system.
Alcohol and the brain Any chemical that alters mood, feelings, co-ordination, perception, or behaviour, alters the cells in the brain and disrupts their normal chemical behaviour. When alcohol enters the blood stream it travels to the brain.
Alcohol can affect millions of nerve cells and change communication patterns throughout the brain. Deep inside the brain alcohol can affect the areas that control aggression, hunger and thirst, pleasure and pain, and body temperature.
These effects are produced because alcohol inhibits blood from transporting oxygen to brain cells. When brain cells are deprived of oxygen, they become impaired and possibly die!
Because the brain matures more slowly than other organs of the body, it may be even more susceptible to certain permanent, irreversible effects of alcohol.
The hypothalamus is the portion of the brain that controls lour automatic reflexes: When alcohol is present in the blood stream it directly affects the hypothalamus, possibly damaging it, particularly during the adolescent years.
In addition, alcohol has a profound effect on the frontal lobe- the part of the brain that allows us to analyse and program our behaviour. These processes require a tremendous amount of energy. The depressant nature of alcohol directly lowers die energy centre in the brain.
Those who lower the energy levels in the brain by using alcohol or other toxic chemicals, lose not only mental capacity, but their ability to realise they have lost it. Adolescence is a time of changing attitudes, perception and behaviour.Alcohol’s activity on the dopamine site in the brain’s reward center produces the pleasurable feelings that motivate many people to drink in the first place.
As a Psychology Today article on this topic discusses, the degree to which alcohol impacts a person’s mood, behavior, and neurological functioning depends in part on whether the blood alcohol content (BAC) is elevating or decreasing. | Effects of Alcohol on The Brain | Biology | | | This paper is on the effects of alcohol on the brain, the damage that it causes to the nervous system and other organs, and the long term effects of alcohol dependency.
