The brain plays a leading role in addiction, just as it plays a role in all human behavior. The choice to try a drug is a decision that that is centered in the executive portion of the brain, the prefrontal cortex. Once consumed, the drug delivers a powerful stimulus to the nucleus accumbens, a cluster of nerve cells below the cerebral cortex, which responds quickly by releasing a flood of dopamine. http://www.scoota.ru/video/509%20title= The neurotransmitter dopamine is often called “the pleasure molecule,” but it is more correctly defined as a chemical that underlies motivation. There are a few interventions derived specifically from behavioral economicssuch as EFT and enhancements of Brief Motivational Interventions. Generally, theseinterventions encourage a greater focus on and valuation of longer term prosocialreinforcers.
Psychodynamic theories
The desire for reward ultimately becomes a prison from which it is difficult—but not impossible—to escape. • the nucleus accumbens, a cluster of cells below the cortex in the basal forebrain that produces the urge to pursue a goal. Sometimes called the “pleasure center” of the brain, it is a key player in the reward circuitry of the brain and releases dopamine in response to positive experiences and the anticipation of such experiences. In addition, mounting evidence suggests that the brain changes of addiction do not reflect abnormal processes—they are the same processes involved in all learning. And the addicted brain returns to normal, gradually rewiring itself after substance use stops.
The Informants
Yes, it is clear that most people whom we would consider to suffer from addiction remain able to choose advantageously much, if not most, of the time. However, it is also clear that the probability of them choosing to their own disadvantage, even when more salutary options are available and sometimes at the expense of losing their life, is systematically and quantifiably increased. There is a freedom of choice, yet there is a shift of prevailing choices that nevertheless can kill. We therefore argue that a contemporary view of addiction as a brain disease does not deny the influence of social, environmental, developmental, or socioeconomic processes, but rather proposes that the brain is the underlying material substrate upon which those factors impinge and from which the responses originate.
2. Addiction: a behavioural disorder
- The neurotransmitter dopamine is often called “the pleasure molecule,” but it is more correctly defined as a chemical that underlies motivation.
- This theory differentiates ‘wanting’ a reward from ‘liking’ the reward and highlights the insubstantial contribution of neural adaptations to the latter (Berridge and Robinson, 2016).
- The unravelling of the cause and symptomatology of addiction has diluted morality arguments and replaced them with the concept of addiction as a brain disease (culminating in the US National Institute on Drug Abuse 1997 report) (Heilig et al., 2021).
- More importantly, this study demonstrated the mediating roles of loneliness and COVID-19 anxiety on smartphone addiction.
- These data suggest that commonly used diagnostic criteria alone are simply over-inclusive for a reliable, clinically meaningful diagnosis of addiction.
They either spoke about their parents as ‘betrayers’ and ‘bastards’ or as loving and supportive people. Siblings, grandparents, aunts, and uncles often represented stability and safety in families with parental SUD or mental health problems. The feeling of safety was closely related to violent relationships, housing, the neighbourhood or finances.
Comment on Heilig et al.: The centrality of the brain and the fuzzy line of addiction
Close to a quarter of a century ago, then director of the US National Institute on Drug Abuse Alan Leshner famously asserted that “addiction is a brain disease”, articulated a set of implications of this position, and outlined an agenda for realizing its promise [1]. The paper, now cited almost 2000 times, put forward a position that has been highly influential in guiding the efforts of researchers, and resource allocation by funding agencies. A subsequent 2000 paper by McLellan et al. [2] examined whether data justify distinguishing addiction from other conditions for which a disease label is rarely questioned, such as diabetes, hypertension or asthma. It concluded that neither genetic risk, the role of personal choices, nor the influence of environmental factors differentiated addiction in a manner that would warrant viewing it differently; neither did relapse rates, nor compliance with treatment.
The results of the study suggest that college students experiencing social isolation are at greater risk for smartphone addiction, and the core factor leading to their smartphone addiction is the subjective psychological state triggered by campus isolation and social distancing, such as loneliness and anxiety. This study enriches our understanding of why and how college students experiencing social isolation exhibit smartphone addiction. The findings also extend the theory of antecedent http://www.religare.ru/2_54800.html research on cell phone addiction in the context of public health crises. This study also provides a theoretical basis and practical guidance for addressing smartphone addiction among college students in the context of public health crises. The ability of an addiction model to account for DSM criteria is not ameasure of its potential utility or impact. If addiction were just problem behavior,a bad habit, or a physical dependence it would be readily addressable in animals andpeople.
Within human self-administration studies, the variability of addictive tendencies in patients suffering from substance use disorders can be established in research settings. Patterns of addiction characteristics such as daily drug use, bidirectionality of social factors, and drug-seeking or drug-taking behaviour depending on experimental conditions can be determined within the research setting (Venniro et al., 2016). Animal models have informed our psychological and neurobiological understanding of addiction and thus driven treatment development. In the case of alcohol use disorder (AUD), for example, results from animal experiments https://livewirerecordings.net/2024/01/29/negative-impact-of-excessive-entertainment-on-society/ were translated clinically to specifically licenced medications including acamprosate and naltrexone (Spanagel, 2017). In addressing the utility of rodent models of addiction, Crabbe describes thereductionist animal model approach to understanding a complex human behavior byfirst manipulating rodents to simulate distinct key behaviors of addiction and thensynthesizing the inferred fundamental principles into a heuristic model. In keepingwith the article theme, Crabbe discusses the extent to which rodent models canelucidate each of the diagnostic criteria of DSM-5 (American Psychiatric Association, 2013) SUD diagnoses.
Usage and gratification theory and CIU theory suggest that smartphone addiction in college students is a positive response to stressful events such as public health emergencies in an attempt to meet psychological needs, although it may lead to negative outcomes (e.g., addiction). People use smartphones for a variety of purposes (Katz et al., 1974), including information retrieval, facilitating social engagement, alleviating boredom, providing distractions, mitigating negative feelings, and enhancing positive emotions (Brailovskaia et al., 2020). Notably, loneliness mediated the relationship between social isolation and smartphone addiction. Individuals with high levels of loneliness are prone to develop cell phone addiction (Shen and Wang, 2019). In addition, COVID-19 anxiety mediated the relationship between social isolation and smartphone addiction.
- Instead, research indicates that it is more related to what else is, or isn’t, going on in a person’s life that makes the sensation a substance induces so attractive.
- Synthesized, the notion of addiction as a disease of choice and addiction as a brain disease can be understood as two sides of the same coin.
- However, as we will see below, in the case of addiction, it contributes to large, consistent probability shifts towards maladaptive behavior.
Addiction is described as a defensive strategy to avoid feeling of helplessness or powerlessness. The addict tries to compensate via addictive behavior for painful subjective states of low self-esteem, doubts, and anxiety. An addict substitutes an imaginary world, where he is in complete control, for the real world, where he feels useless and out of control. The addiction problem prevents the user from understanding her distress, as well as the development of an emotional capacity to self-soothe. For Freud, the goal of psychoanalysis was to strengthen the ego, and to give it more control over the id and more independence from the superego. He believed that most mental disorders (e.g., anxiety) were due to the effect of unrestrained feelings.
