The inSignificance of the Addiction Debate SpringerLink

Ask the mother who lost her 19-year-old son — the laughing family prankster who earned a full-ride college scholarship as a solid student and star second baseman — to drugs. When it is an addiction, a person might have triggers, such as places or interactions linked to their drug use. Cravings can last for years and feel uncontrollable even if and when the person becomes sober. Dopamine causes euphoria and encourages the person to repeat pleasurable behaviors.

Whether addiction is caused by pathological brain dysfunction is not as obvious, however, as it apparently appears to many scientists. There are scientific accounts of addiction according to which it does not involve any brain pathology at all. On the theories I have in mind, explaining addiction requires us to postulate non-pathological brain mechanisms.

Berridge, 2007 suggests that the role of dopamine is incentive salience, not learning. Berridge points out that learning about the relationship between a stimulus and a reward can occur without dopamine. In mice genetically engineered to be unable to synthesize dopamine, normal learning seems to occur. It also occurs in mice that have virtually no mesolimbic dopamine due to neurochemical lesioning. Further, activation in the ventral pallidum, downstream of the mesolimbic dopamine system, is stronger in response to a second, redundant, predictor of reward than in response to the first. Since the second predictor adds no new information, we ought to expect a smaller response to the second predictor than to the first if the dopamine system was itself a reward prediction system.

In scientific and clinical usage, addiction typically refers to individuals at a moderate or high severity of SUD. This is consistent with the fact that moderate-to-severe SUD has the closest correspondence with the more severe Top 5 Questions to Ask Yourself When Choosing Sober House diagnosis in ICD [117,118,119]. Nonetheless, akin to the undefined overlap between hazardous use and SUD, the field has not identified the exact thresholds of SUD symptoms above which addiction would be definitively present.

Lessons from genetics

Understanding the brain’s role in addiction can help reduce negative perceptions and attitudes of those struggling with substance use disorders. Because addiction is typically a chronic disorder characterized by intermittent relapses, a short-term, one-time treatment is generally not sufficient. Individuals who enter and remain in treatment can manage their addiction and improve their quality of life. The disease model of addiction implies that addiction is like such ailments as heart disease and diabetes. Like those diseases, addiction may result from a combination of genetic factors and lifestyle choices.

In this chapter Heyman also examines factors related to the incidence of drug abuse and finds several that support his view that drug abuse results from normal choice processes. That marriage may be protective for drug abuse is consistent with his view that alternative sources of consequences for choices are crucial. The CM raises some important questions regarding the meaning of uncontrollable, compulsive and involuntary behaviour. Although not disagreeing on the neural processes that are the basis of said behaviour, it is considered a problem that addiction seems to be equated with a lack of control without explaining what that means [25]. On what basis is addiction considered to consist of fully uncontrollable actions? Heyman suspects that the assumption of involuntariness of addiction that the BDM explains is inferred from the fact that addictive behaviour is self-destructive.

An ever-increasing body of scientific evidence suggests that the transition from voluntary user to addict occurs through a combination of processes, including a series of brain changes or neuroadaptations that result from repeated drug exposure. Because changes in brain structure and function are fundamental to the development and expression of addiction, it qualifies as a brain disease–a brain disease expressed as compulsive behavior. If my claim that the neural correlates of addiction do not cause impairment in all accessible environments is true, addiction is not a brain disease in the way in which the other conditions Leshner (1997) cites are. Addiction differs from paradigm brain diseases in that its correlates do not cause impairment across all, or nearly, accessible environments. For some conditions that cause suffering, neural correlates are sufficient to cause an impairment and for some they are not; only those which fit into the former class count as brain diseases. Through a practice of self-reflection in early recovery, I started to explore some of the bad things had happened to me in my childhood.

The disease model for addiction states that these brain changes can persist after the person has stopped using a substance. Often, an addictive disorder may be referred to as a habit, compulsion, or dependency on a particular substance or action. However, the American Medical Association and the American Society of Addiction Medicine classify addiction as a disease. Clinical understanding of addiction continues to improve as the stigma surrounding these behaviors is addressed. Ultimately, there are a number of different treatments that have been proven to be effective in helping people to stop using drugs and stay clean and sober.

Addiction is not a brain disease (and it matters)

In recent decades, researchers began to label addiction as a disease rather than a behavioral choice. This decision stems primarily from how addiction affects the brain by changing it, progressively forcing an individual to crave the drug until use eventually becomes an unconscious act rather than a conscious choice. While this stigma is still common today, modern addiction can affect any person regardless of their socioeconomic class, ethnicity, and background. One use is all it takes for some drugs to set a person on the wrong course, and even legal drugs such as prescription opioids can easily catapult addiction if they are misused.

First, people may appear to remit spontaneously because they actually do, but also because of limited test–retest reliability of the diagnosis [31]. This is obviously a diagnosis that, once met, by definition cannot truly remit. Lifetime alcohol dependence was indeed stable in individuals recruited from addiction treatment units, ~90% for women, and 95% for men. In contrast, in a community-based sample similar to that used in the NESARC [27], stability was only ~30% and 65% for women and men, respectively. The most important characteristic that determined diagnostic stability was severity. Diagnosis was stable in severe, treatment-seeking cases, but not in general population cases of alcohol dependence.

Women’s Health

An unfortunate side effect of tolerance is that the person may also find less and less pleasure in other activities they enjoyed, such as eating or social events. In dire circumstances, it can contribute to conditions such as heart disease. As the person continues to use the drug, the brain must make specific adaptations.

• HCRC is a CARF accredited organization and has been providing addiction treatment services for over 32 years in the New England area.
• What is mostly contested is merely the extent to which the capacities of addicts are affected.
• However, when physically dependent and in a state of withdrawal, their choice preference would reverse [102].
• There are certainly still behavioral risk factors, which come down to an individual’s likelihood to actively seek out substances as new experiences and try drugs or overindulge in alcohol.
