5 damaging myths about addiction Myth No. 1: There is an addiction gene. There is no single gene, or set of genes, that determines whether or not a person will become an addict. And even if a person's parents are addicts, it doesn't mean they will be too. Current addiction research shows that roughly 50% of addiction tendencies are attributable to genes.

The Big Question: Why Do Some People Get Addicted and Others Donât? Vulnerability to this disease varies and is based on differing factors. It can affect one person and pass another. It can take hold of one family member’s life, but make no impact on his brother’s. It can skip generations or show first signs in a family with no history of addiction present. Primary factors are genetics (family history of addiction), age of first use, environment and existing mental health problems.

The University of Texas at Dallas Barnes said there is no gene for criminal behavior. He said crime is a learned behavior. “But there are likely to be hundreds, if not thousands, of genes that will incrementally increase your likelihood of being involved in a crime even if it only ratchets that probability by 1 percent,” he said. “It still is a genetic effect.

Understanding Addiction Dopamine not only contributes to the experience of pleasure, but also plays a role in learning and memory—two key elements in the transition from liking something to becoming addicted to it. According to the current theory about addiction, dopamine interacts with another neurotransmitter, glutamate, to take over the brain’s system of reward-related learning. This system has an important role in sustaining life because it links activities needed for human survival (such as eating and sex) with pleasure and reward.

- For many decades it's been widely accepted that alcoholism (or addiction) is a disease. The disease concept is taught in addiction training programs and told to patients in treatment programs. It is unquestioned by public figures and the media. agree that addiction is not a disease, but believe that it IS an illness. The reward-seeking element can rapidly disappear, even if this is what got an addict started in the first place. This is rapidly replaced by a physical need, mainly a need to avoid the intense pain of withdrawal.

- Although variations in several of these genes have been associated with opioid addiction, it is unclear how these genetic changes influence the way in which the nervous system responds to opioids. Opioid addiction is a complex disorder, and nongenetic factors also play a critical role. Factors that have been shown to increase the risk of opioid addiction include a history of substance abuse; depression or other psychiatric disorders; childhood abuse or neglect; and certain personality traits, including impulsivity and sensation-seeking.

Is Addiction a Disease? Whether or not addiction is a disease has other consequences as well. If addiction is a disease, then it isn’t a moral failure or a character flaw. Although the results of addiction may be criminal charges and toxic behaviors, if it is a disease, the root cause cannot be blamed on a spiritual defect alone.

Researchers Identify Alcoholism Gene The gene is also involved in the process of alcohol tolerance, dependence, and withdrawal symptoms, writes Pandey. A section of the brain -- called the central amygdala -- is another piece of this puzzle. Both the CREB gene and the central amygdala have been linked with withdrawal and anxiety.

How neurons talk to each other Many genes with roles in addiction were identified with the help of animal models, especially mice. Because the reward pathway—and many of the genes that underlie it—functions in much the same way in mice as it does in people, mice are leading the way in identifying addiction genes.ot every addict will carry the same gene, and not everyone who carries an addiction gene will exhibit the trait. However, multiple lines of research show that addiction is influenced by genes. There are many ways that genes could cause one person to be more vulnerable to addiction than another.

Male Impulsivity & Addiction Linked to One Gene Addiction and impulsivity have a genetic link in men, according to a new study. The gene, a snippet of DNA called NRXN3, has previously been linked to nicotine dependence, as well as alcohol dependence, opiate addiction and obesity. The new research suggests a common denominator of impulsivity underlies all of these troubles.

Causes & Risk Factors Causes & Risk Factors. When it comes to any type of addiction there are still debates among experts as to the underlying causes. Part of what muddies the waters is the disagreement over whether an addiction is a disease or a habit. An addiction to sex, which is still not fully recognized as a true addiction by many, is certainly not immune to the controversy.

Binge-eating is in the genes Binge-eating is in the genes. by ROSALIND RYAN, femail.co.uk. Binge-eaters often say they have no control over their eating habits - now science has managed to prove them right. New research has found that a faulty gene, rather than feeble willpower, could be responsible for binge-eating. Binge-eaters frequently and compulsively stuff themselves with food, often in secret, and tend to feel ashamed afterwards. They are usually, but not always, overweight.
