Over time, the transfer of memory between short term (a few minutes) to long term (just a few months or possibly forever) becomes distorted and the brain is unable to store long term memories or knowledge anymore [2, 12].

Effects on Motor Control

A serious consequence of drinking is damage to the central nervous system (CNR). When a person decides they want their body to perform an action, the CNR sends a signal to the brain which will relay this information to the part of the body needed to perform the action. Since alcohol is a depressant of the CNS, it significantly slows down the signals (neurons) and as a result the person will begin thinking, speaking and moving slower; as you can see in the figure below [19]. After continuous damage to the
CNR, different neurotransmitter receptors will become permanently damaged; to list a couple: serotonin(associated with receptor depression) and dopamine receptor (emotional hormone). When these receptors are damaged, the brain can no longer function properly causing shaking

    Alcohol Annotated Bibliography

    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.…

    The Effects Of Alcohol On The Brain

    Through the years scientists have discovered that there is more to the brain than previously thought. They have learned that inside the brain there is a synapse or an area that is open between the axon of a nerve and the dendrite of another nerve. The synapse entails the neurotransmitters, mitochondria, postsynaptic ending that has receptors sites for the neurotransmitters, and a synaptic cleft.…

    Effects of Chronic Alcohol Consumption on Cardiovascular Autonomic Functions

    Chapter 1 INTRODUCTION Alcohol drinking has been practiced in the majority of human society since early times. Alcohol (ethyl alcohol) is a drug which acts principally as a depressant on central nervous system. Its effects on behavior are well known and regular use gives rise to an increased tolerance, so that the drinker needs to take gradually increasing amounts to obtain the same effect. Chronic excessive alcohol consumption leads to life threatening hazards (Best, 1999). Alcohol related diseases are rising rapidly in Western countries as well as in Asia. According to the World Health Organization (2008), there are about 2 billion people worldwide who consume alcoholic beverages and 76.3 million with diagnosable alcohol related disorders. Alcohol consumption is the leading risk factor for disease burden in developed countries and the third largest risk factor in developing countries (WHO, 2008). Excessive alcohol intake has detrimental effects on the cardiovascular system leading to cardiomyopathy, coronary heart diseases, hypertension and hemorrhagic stroke (Klatsky, Armstrong and Friedman, 1990). As Schuckit (2008) described, alcohol can also damage the liver, pancreas, stomach, intestine and central nervous system. The effects of alcohol on central nervous system are generally proportional to blood ethanol concentration. However, individuals who are habituated to alcohol may have few symptoms, despite massive blood ethanol concentration. Young people who are not accustomed to alcohol may become comatose at more modest blood ethanol concentration (Johnson and Robinson, 1988). Peripheral neuropathy is a common finding in chronic alcoholics. There also is a population having autonomic neuropathy in chronic alcoholics (Duncan et al., 1980). Johnson and Robinson (1988) reported that vagal neuropathy in chronic alcoholics is associated with significantly higher mortality than in general population. They also suggested that the major cause of death in chronic…

    Teenage Life

    In the human body, ethanol affects the gamma-aminobutyric acid (GABA) receptors and produces a depressant (neurochemical inhibitory) effect. Ethanol is similar to other sedative-hypnotics such as barbiturates and benzodiazepines both in its effect on the GABAA receptor, although its pharmacological profile is not identical. It has anxiolytic, anticonvulsant, hypnotic, and sedative actions similar to many other sedative-hypnotic drugs. Ethanol is also cross-tolerant with benzodiazepines and barbiturates.[3] In fact, a synthetic alcohol based on benzodiazepines is currently developed by a team at Imperial College London, led by Professor David Nutt (chair of ISCD). The alcohol substitute give the drinker the effects of drunkenness without many of the risks of alcohol;[4] Accordingly to ISCD alcohol was the most harmful of all drugs considered, scoring 72%. Alcohol is the most available and widely abused substance and its chronic consumption causes neurobehavioral disorders.[5] A high-functioning alcoholic (HFA) is a…

    Effects of drinking Alcohol

    Alcohol has many short-term affects and a few long-term effects on a person’s brain. A few short term affects include: difficulty walking, slowed reaction time, slurred speech, blurred vision, and impaired memory. These are usually noticeable after a few drinks and can easily be resolved when the drinking stops. On the other hand, the long term effects on the brain handicap an individual even after they have sobered up. A few factors that can determine the extent of what alcohol can do to the brain are: a person’s age, gender, general…
