Definition: Addiction Help

nnAddiction was a term used to describe a devotion, attachment, dedication, inclination, etc. Nowadays, however, the term addiction is used to describe a recurring compulsion by an individual to engage in some specific activity, despite harmful consequences to the individual's health, mental state or social life. The term is often reserved for drug addictions but it is sometimes applied to other compulsions, such as problem gambling, and compulsive overeating. Factors that have been suggested as causes of addiction include genetic, biological/pharmacological and social factors.n

nTerminologynNot all doctors agree on what addiction or dependency is. Traditionally, addiction has been defined as being possible only to a psychoactive substance (for example alcohol, tobacco and other drugs) which ingested cross the blood-brain barrier, altering the natural chemical behavior of the brain temporarily. nnIt is generally accepted that addiction is a disease, a state of physiological or psychological dependence or devotion to something manifesting as a condition in which medically significant symptoms liable to have a damaging effect are present.n

nnPhysical dependencynnPhysical dependence on a substance is defined by the appearance of characteristic withdrawal symptoms when the substance is suddenly discontinued. Opiates, benzodiazepines, barbiturates, alcohol and nicotine induce physical dependence. On the other hand, some categories of substances share this property and are still not considered addictive: cortisone, beta-blockers and most antidepressants are examples. So, while physical dependency can be a major factor in the psychology of addiction and most often becomes a primary motivator in the continuation of an addiction, the initial primary attribution of an addictive substance is usually its ability to induce pleasure, although with continued use the goal is not so much to induce pleasure as it is to relieve the anxiety caused by the absence of a given addictive substance, causing it to become used compulsively. nnThe speed with which a given individual becomes addicted to various substances varies with the substance, the frequency of use, the means of ingestion, the intensity of pleasure or euphoria, and the individual's genetic and psychological susceptibility. Some people may exhibit alcoholic tendencies from the moment of first intoxication, while most people can drink socially without ever becoming addicted. Opioid dependent individuals have different responses to even low doses of opioids than the majority of people, although this may be due to a variety of other factors, as opioid use heavily stimulates pleasure-inducing neurotransmitters in the brain. nnPsychological dependencynnPsychological dependency is a dependency of the mind, and leads to psychological withdrawal symptoms (such as cravings, irritability, insomnia, depression, anorexia etc). Addiction can in theory be derived from any rewarding behaviour, and is believed to be strongly associated with the dopaminergic system of the brain's reward system (as in the case of cocaine and amphetamines). Some claim that it is a habitual means to avoid undesired activity, but typically it is only so to a clinical level in individuals who have emotional, social, or psychological dysfunctions (psychological addiction is defined as such), replacing normal positive stimuli not otherwise attained.nnIt is considered possible to be both psychologically and physically dependent at the same time. Some doctors make little distinction between the two types of addiction, since the result, substance abuse, is the same. However, the cause and characteristics of each of the two types of addiction is quite different, as is the type of treatment preferred.nn

nMethods of CarenWhile addiction or dependency is related to seemingly uncontrollable urges, and arguably could have roots in genetic predispositions, treatment of dependency is conducted by a wide range of medical and allied professionals, including Addiction Medicine specialists, psychiatrists, and appropriately trained nurses, social workers, and counselors. Early treatment of acute withdrawal often includes medical detoxification, which can include doses of anxiolytics or narcotics to reduce symptoms of withdrawal. An experimental drug, ibogaine,[2] is also proposed to treat withdrawal and craving. Alternatives to medical detoxification include acupuncture detoxification. In chronic opiate addiction, a surrogate drug such as methadone is sometimes offered as a form of opiate replacement therapy. But treatment approaches universal focus on the individual's ultimate choice to pursue an alternate course of action.nnTherapists often classify patients with chemical dependencies as either interested or not interested in changing. Treatments usually involve planning for specific ways to avoid the addictive stimulus, and therapeutic interventions intended to help a client learn healthier ways to find satisfaction. Clinical leaders in recent years have attempted to tailor intervention approaches to specific influences that affect addictive behavior, using therapeutic interviews in an effort to discover factors that led a person to embrace unhealthy, addictive sources of pleasure or relief from pain.nn
