Taylor Greubel Mrs. Garrels Biology May 19, 2014 The Addictive Mind The human brain is the moist complex and sensitive organ in the entire body. It is constructed of a complex network or billions of sensitive nerve cells called neurons. Neurons are electrically excitable cells that process and transmit information through electrical and chemical signals. One of the down falls of this incredible organ, is the neurological condition that the brain is so prone to, known as addiction. Addiction is the dependency of a particular substance, thing, or activity. Unfortunately, you can become addicted to almost anything in the world. The most common substances the brain becomes addicted to would be caffeine, nicotine, alcohol, and controlled substances. Addiction is truly a disease; addiction is a chronic relapsing disease that affects your brain and neurotransmitters. Certain things the brain can become addicted to, like for example drugs and alcohol, can change the brains structure and function after repetitive use many people believe that addiction is a choice the addict makes which is untrue. The initial intake of the substance is usually always a conscious decision, but the dependence on a certain substances different for everybody. It may only take one time for the addict to become addicted; every person has a different tolerance level. After the initial intake, the substance is already causing changes in the brain that corrode the self control and ability to make the right behavioral choices. Some may not become addicted while others do; it all depends on the person’s biology. Scientist have discovered that the genetic coding of a person accounts for about 50% of the addicts vulnerability to addiction while the other 50% is the en... ... middle of paper ... ...Depending on the substance, drugs and alcohol will transform your brains shape and functional ability, but with any substance you can become addicted to, there is always a “need” aspect. The caffeine addiction experiment Jennifer Temple conducted shows that the caffeine intake caused the children to perform at a different level than they would have with no caffeine in their bodies. When caffeine enters your body it mimics the chemical adenosine that is produced by neurons. When you drink caffeine, the neurons are released throughout the entire day and as it produces more, it starts to shut down your nervous system. Caffeine, drugs, alcohol, and nicotine are all just chemical substances used to mimic different natural chemical substances and process to trick our mind. The most complex organ in our body can be so easily tricked and destroyed by man-made creations.
George F. Koob defines addiction as a compulsion to take a drug without control over the intake and a chronic relapse disorder (1). The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association defined "substance dependence" as a syndrome basically equivalent to addiction, and the diagnostic criteria used to describe the symptoms of substance dependence to a large extent define compulsion and loss of control of drug intake (1). Considering drug addiction as a disorder implies that there are some biological factors as well as social factors.
According to Leshner, drug addiction is a chronic brain disease that is expressed in the form of compulsive behaviors (Leshner, 2001). He believes that drug addiction is influence by both biological, and behavioral factors, and to solve this addiction problem we need to focus on these same factors. On the other hand, Neil Levy argues that addiction is not a brain disease rather it is a behavioral disorder embedded in social context (Levy, 2013). I believe, drug addiction is a recurring brain disease that can be healed when we alter and eliminate all the factors that are reinforcing drug addiction.
Before giving a broad overview on the definition of the Biopsychosocial (BPS) Model of Addiction, it must be understood that there is no simple unified theory of addiction that is universally accepted in the health world. This makes the definition of the BPS Model of Addiction not just a simple, one to two sentence definition of what this is, but rather a description of the components within the BPS model of addiction. In a broad sense, this model takes the stand that biological, psychological, and social aspects all contribute to the understanding of addiction. In short, the BPS model of addiction is an attempt to further explain addiction – how it occurs, and how it is maintained. Below is an image (Basic Representation of the BPS Model, 2017) representing this model
Addiction /ə-ˈdik-shən, a-/ noun 1. A strong and harmful need to regularly have something (such as a drug) or do something (such as gamble), 2. An unusually great interest in something or a need to do or have something (Addiction). Addiction can cause a person to sabotage their lives in order to get their next fix, whether that be scoring another gram of coke or a double with cheese, a large fry, and a large soda. Addicts are stuck in a constant cycle of getting cravings, going through with their ritual, using, experiencing guilt, and being emotionally triggered, thus bringing them back to the beginning. Now, most people when they hear the word “addiction”, the first thing that comes to their mind is drugs. However, if a vast majority of individuals
The fact that addiction is a brain disorder is a new detail that I learnt from the HBO video. As pointed out by Dr. Volkow, addiction as a brain disease renders the addicts unable to control themselves in relation to curbing their addiction problem. In conceptualizing addiction as a brain disease, Volkow illustrates this standpoint with the fact that the brain has a “natural reward system” that facilitates the learning of “behaviors that are necessary for survival” (NIDA 2006). Learning that the abused drugs take over this system – the dopamine system of the brain - was pivotal in finally grasping the rationale behind referring to addiction as a brain disorder. The brain with time becomes dependent on the abused drugs. This arises from the fact that natural rewards no longer have the capability to produce “normal levels of dopamine or pleasure” (NIDA 2006). As time goes on, the continued intake of drugs subsequently makes the addict lose all control over their use and dependen...
Addiction is a disease that causes many neurological effects on the brain. In fact, addiction is included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is the standard reference for psychiatric illnesses (DSM-5) and it affects ten percent of the population (Understanding). Most drugs release chemicals that effects the mid-brain and changes its chemical make up. Specifically, nerve cells in the brain release dopamine when humans engage in pleasurable activities, like eating good food, exercise, and sex (Understanding). This causes the person to seek out that pleasurable activity again and again (Substance Abuse). Drugs, from alcohol and marijuana to heroin, also cause the brain to release dopamine, but faster and stronger than most activities. (Mandal) With repeated use, the addict becomes accustomed to this stronger, quicker pleasure sensation and can no longer feel the milder pleases of normal activity. In this way, the brain becomes “broken,” and the addict continues to seek that good feeling only experienced with drugs (Substanc...
The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
Specific Purpose: To inform my Audience on how addiction works in the brain, how it is related to survival, why some people are more vulnerable to addiction than others, and why addiction should be treated as a disease.
“Addiction is a brain disease expressed in the form of compulsive behavior,” says by Alan Leshner in his article, “Addiction Is a Brain Disease” featured in the book Drug Abuse: Opposing Viewpoints. Addiction has a variety of meanings depending on what your viewpoint of addiction. According to dictionary.com, the concrete definition of the word addiction is, “the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming, as narcotics, to such an extent that its cessation causes severe trauma.” Basically various doctors and therapist consider addiction to be a genetic disorder. “Provocative, controversial, unquestionably incomplete, the dopamine hypothesis provides a basic framework for understanding how a genetically encoded trait — such as a tendency to produce too little dopamine — might intersect with environmental influences to create a serious behavioral disorder. Therapists have long known of patients who, in addition to having psychological problems, abuse drugs as well. Could their drug problems be linked to some inborn quirk?” (Nash, and Parker, pg 2 of 8). Along with addiction being possibly a genetic disorder, a minority of scientist believe that the word ‘addiction’ is too broad in its denotation. “If addiction means ‘compulsive, out of control use of a dangerous drug’ is this the same as a person’s being ‘addicted’ to a cell phone? Scientist cannot work or live with this imprecision.” (Erickson, 2 of 253). They believe that the word is misunderstood in denotation. “It is important to correct the common misimpression that drug use, abuse and addiction are points on a single continuum along which one slides back and forth over time, moving from user to addict, th...
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. Addiction is a brain disease expressed in the form of compulsive behavior (Leshner.) Both devolping
Addiction is a condition that develops from a simple immoral act or increased dependency on drugs for normal functioning of the body. While it has traditionally been considered as a condition brought by behavioral problems, addiction is a disease of the brain as evident in the findings in neuroscience, genetics, and biological studies. The condition is a disease because of the significant effects it has on the structure and function of the brain.
Addiction is a chronic brain disease characterized by compulsive drug and substance use. Despite its harmful consequences to the human body, addicts continue to seek for more drugs to keep their systems active. Millions of people abuse drugs and substances in the world today. As a result of substance abuse, addicts can easily lose control of their actions. Addiction is a long-lasting brain illness that disrupts the normal body functioning. It holds the brain hostage.
Addiction is a very strong word that brings along many negative connotations. When we think of an addiction we imagine someone who depends on a certain substance, most likely alcohol to have their needs met. Addiction is defined by the Webster dictionary as, "a compulsive need for and use of a habit-forming substance (as heroin, nicotine, or alcohol) characterized by tolerance and by well-defined physiological symptoms upon withdrawal." Even though our society sees addiction and only applies the word to drug addicts and alcoholics, there is a much wider range of subjects that fall under the umbrella of what an addiction truly is. An addiction is a dependency on any kind of materialistic object that you use on a day to day basis that brings
So, it is clear that addiction is all around us and can attack anyone of us at any given time. Even studies conducted show that people neglect to speak around their dependency for two primary reasons. Foremost, because people do not comprehend, or they bear a total misconception to their addiction, that they do not realize that addictions can be critical to their overall wellness. Moreover, second, many people believe being an addict will never happen to them, but, in reality, most addictions start off as simple little habits. Such as starting with one drink after dinner and before you know it you are drinking several drinks a day. However, one does not opt to be addicted to a substance, because addictions are physical defects in the brain, a disease, and not one’s choice.
Drug abuse and addiction are issues that affect people everywhere. However, these issues are usually treated as criminal activity rather than issues of public health. There is a conflict over whether addiction related to drug abuse is a disease or a choice. Addiction as a choice suggests that drug abusers are completely responsible for their actions, while addiction as a disease suggests that drug abusers need help in order to break their cycle of addiction. There is a lot of evidence that suggests that addiction is a disease, and should be treated rather than punished. Drug addiction is a disease because: some people are more likely to suffer from addiction due to their genes, drug abuse brought on by addictive behavior changes the brain and worsens the addiction, and the environment a person lives in can cause the person to relapse because addiction can so strongly affect a person.
