Alcohol is a substance that can cause diseases to spread throughout the body and brain that may cause eternal damage to the organs. The effects of alcohol consummation may vary with damage to the brain, organs, and appearance. "Alcohol travels through your bloodstream and can damage your brain, stomach, liver, kidneys, and muscles". ("Above The Influence") With knowing that this substance is this powerful to cause damage to these internal and external organs there are several affects that comes behind them as well. The act of alcohol on the brain has a major effect because it inhibits a person’s thought process.
Some people feel that addiction is really a brain disease that affected individuals cannot control, while others feel that it is a test of strength and will. Both arguments have valid points that can be discussed further. Is addiction... ... middle of paper ... ...t is so hard for addicts to quit on their own. Quitting is not just a sheer force of will. When your brain is affected and changed it makes it even harder.
It tends to excite the functions of inhibitory neurotransmitters, such as GABA, glycine, and adenosine, ... ... middle of paper ... ...ppocampus of alcoholics. This was found through careful analyses of brain structures and contiguous MRI slices of the target brain structure (Sullivan et al., 1995). The hippocampus is involved with processes such as memory formation, spatial orientation, and formation of emotions/responses. Damage to this structure of the brain could attribute to some of the behaviours that are associated with alcoholism, such as difficulties in recovering memories, confusion, and heightened emotional states. In conclusion, the use of alcohol has many short and long term effects.
It relieves anxiety, stress, and enhances the feeling of euphoria. Although alcohol is considered as a drug, it depresses vital functions of the human body and affects each single organ of it. Mainly, the central nervous system (CNS) is affected by alcohol since it crosses the blood brain barrier. There are several neurotransmitters in the brain that are modulated by alcohol. However, researchers' attention was mostly focused on the glutamate and γ-aminobutyric acid (GABA), the main excitatory and inhibitory neurotransmitters in the CNS, respectively.
All drugs negatively affect the brain. That is why drugs can make your body feel high, low, slow, or fast, or make the user see things that are not truly there. Some drugs can hurt your brain and affect how you act and how your body feels. These problems might last just a little while, or for the rest of your life. Drug abuse and addiction will often change your brain chemistry (Effects of Drug Abuse).
Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, according to the National Institute on Drug Abuse. Addiction is normally thought of as drug abuse and alcoholism but people can also be addicted to things such as gambling and sex as well. The controversy on if addiction is a disease or a choice is a continuous debate. Everyone has an opinion on this topic, one side believes it’s a disease, while the other believes it is a choice. Although addiction has been assumed to be a lack of willpower and a weakness, addiction is actually a complex disease that changes the wiring of the brain.
They are compelled to abuse drugs to bring their dopamine function back up to normal, which inquires a larger amount to achieve the normal dopamine high (this can be defined as tolerance). There are many changes in neurotransmitters other than dopamine. Long-term drug abuse causes changes in other parts of our brain chemical system, for example the glutamate which is a neurotransmitter that influences the ability to learn and again it influences the reward circuit. When the optimal concentration is altered by the drug abuse the brain tries to compensate which can cause impairment in cognitive functions. One must remember that changes areas of the brain that are critical such as our judgment, memory, learning, behavior control, and decision making.
The areas most predominately affected in addict’s brains consist of the (1) Pre-frontal cortex region, the (2) and the central-brain. The Mid Brain is responsible for memory and learning, thus the mid brain is where the addiction is created. The areas mentioned above are underactive when sober, yet when the addict “uses” these regions of the brain are stimulated and flooded with massive amounts of dopamine, and serotonin creating an instinctual “reward system”. Unfortunately as the drug raises dopamine to unnaturally high levels the addict finds that the only way to achieve a balance is to continue to use the drug. This changes the hierarchy of important survival needs that release dopamine such as food, water, sex, the mid brain is literally telling the addict they need the drug to survive more so than anything else.
Dopamine-mediated neurotransmissions in various regions plays a key role in mediating the dysphoria associated withdrawal from alcohol and thus reduced function alters perception of alcohol effects. These physiological changes result in withdrawal symptoms, including seizures, anxiety, toxic effects on nerve cells, and altered perception of alcohol’s effects. Any of those symptoms may increase the patient’s potential for relapse and vulnerability to brain damage. With a drinking pattern of repeated bingeing and abstaining, the imbalance occurring during withdrawal may intensify with each successive episode and may culminate in a state of persistent CNS hyperexcitability seen as a augmented withdrawal response.
“ Alcohol mimics the effects of our neurotransmitters, thus provides us with temporary, but artificial boost.” (P10). The outcome of sever alcohol abuse justification of having liver failure, damage to the pancreas, stomach and the way the digestive tracts. Numerous of alcoholics happen to be exceedingly malnourished due to lack of sleep and lack of eating. Alcoholism creates the ability to have a careless outlook for an individual to make bad choices emotionally and physically. Some are convinced that alcohol is an addiction because of the critical chemicals that are in the human brain that has the parts of feelings and responding.
