Understanding the Biological Model of Addiction Nova

Such prevention and treatment interventions would be most effective with policies and related resources that facilitate their enactment, and this may be particularly difficult in countries that devote limited resources to mental health interventions [5, 204]. Evidence that a capacity for choosing advantageously is preserved in addiction provides a valid argument against a narrow concept of “compulsivity” as rigid, immutable behavior that applies to all patients. If not from the brain, from where do the healthy and unhealthy choices people make originate? To resolve this question, it is critical to understand that the ability to choose advantageously is not an all-or-nothing phenomenon, but rather is about probabilities and their shifts, multiple faculties within human cognition, and their interaction. 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.

• The addict’s choice of drug is a result of the interaction between the psychopharmacologic properties of the drug and the affective states from which the addict was seeking relief.
• This is the idea that the biological effects of a substance cause a person to experience a positive sensation.
• The National Survey on Drug Use and Health (NSDUH) reports on substance dependence/abuse rates in various population demographics across the United States.
• The authors outlined an agenda closely related to that put forward by Leshner, but with a more clinical focus.

For instance, they have established that the genetic underpinnings of alcohol addiction only partially overlap with those for alcohol consumption, underscoring the genetic distinction between pathological and nonpathological drinking behaviors [50]. The ambiguous relationships among these terms contribute to misunderstandings and disagreements. Fundamentally, we consider that these terms represent successive dimensions of severity, clinical “nesting dolls”. Not all individuals consuming substances at hazardous levels have an SUD, but a subgroup do. Not all individuals with a SUD are addicted to the drug in question, but a subgroup are. At the severe end of the spectrum, these domains converge (heavy consumption, numerous symptoms, the unambiguous presence of addiction), but at low severity, the overlap is more modest.

For example, males as compared to females tend to more frequently encounter problems with addiction, although the gender composition varies somewhat according to addictive substance or behavior and developmental stage. For example, alcohol and cocaine dependence and pathological gambling are typically male predominant whereas compulsive shopping is more typically identified in females across the lifespan [122]. However, some recent US data have found that girls ages years have rates of alcohol and illicit drug abuse or dependence equal to or greater than those for boys [123, 124]. Despite these differences, some gender-related differences appear relatively consistent across disorders. Differences in motivations for engaging in addictive behaviors also exist between females and males, with women more likely to participate to escape from negative mood states (negative reinforcement) and men more likely to participate to experience positive feelings (positive reinforcement) [ ].

Still, not every biological scenario is as cut and dry as “being born this way.” Many people are born with genetic markers that may not be enough, on their own, to open the door to addiction, but could increase its likelihood when combined with other factors. It all depends on how a gene is “expressed” (i.e., how the specific aspects of its DNA get activated). It’s important to understand the neurological basis of addiction and drug use because it can be helpful in understanding why one person may develop an addiction and another may not. Understanding the causes can help empower you to understand your own circumstances, but let’s not let it limit you in your beliefs about making positive changes in your life. It’s a reciprocal relationship, whereby your experiences shape your brain function, and your brain function shapes your experiences.

So…Is Addiction Really a Biological Disease?

Doing this can help reduce the rate of overdoses, decrease the transmission of needle-related diseases, and connect people to substance use education. People may be addicted to many different things, ideas, or actions at the same time, and society will be unable to identify such dependence. A gene may have all kinds of different https://curiousmindmagazine.com/selecting-the-most-suitable-sober-house-for-addiction-recovery/ biological possibilities but only actually “express” a few. But outside factors can act as catalysts, working to flip genetic switches that can turn other aspects of a gene’s DNA on and off. Getting the right treatment for your child is a process, and navigating the current system requires determination and careful review.

Individuals who are genetically predisposed for addiction enter the world with a greater risk of becoming addicted at some point in their lives. The growing body of data on the neurobiology of addiction has the potential to address more effectively one of the major public health problems facing societies today. A neurodevelopmental perspective with a focus on youth vulnerability could help advance efforts related to early interventions. To treat addiction, scientists have identified several medications and behavioral therapies—especially when used in combination—that can help people stop using specific substances and prevent relapse. Unfortunately, no medications are yet available to treat addiction to stimulants such as cocaine or methamphetamine, but behavioral therapies can help.

Rhesus Monkeys and Biological Addiction

According to Duncan, drug dependence is an avoidance behavior, where an individual finds a drug that produces a temporary escape from a problem, and taking the drug is reinforced as an operant behavior. Some aspects are universal (e.g., the activation of the reward system by drugs of abuse). Yet many other elements are idiosyncratic, such as the intensity of the experience of reward and the functioning of the individual’s mesolimbic dopaminergic pathway in the brain. The biopsychosocial model provides a means of considering the myriad of factors that can contribute to the risk of addiction.

Longitudinal studies that track patient trajectories over time may have a better ability to identify subpopulations than cross-sectional assessments [13]. Risky (hazardous) substance use refers to quantity/frequency indicators of consumption; SUD refers to individuals who meet criteria for a DSM-5 diagnosis (mild, moderate, or severe); and addiction refers to individuals who exhibit persistent difficulties with self-regulation of drug consumption. Among high-risk individuals, a subgroup will meet criteria for SUD and, among those who have an SUD, a further subgroup would be considered to be addicted to the drug.

Internationally, the United States and Eastern Europe contain the countries with the highest substance abuse disorder occurrence (5%-6%). Africa, Asia, and the Middle East contain countries with the lowest worldwide occurrence (1%-2%). Across the globe, those that tended to have a higher prevalence of substance dependence were in their twenties, unemployed, and male. The National Survey on Drug Use and Health (NSDUH) reports on substance dependence/abuse rates in various population demographics across the United States.

This paper, too, has been exceptionally influential by academic standards, as witnessed by its ~3000 citations to date. What may be less appreciated among scientists is that its impact in the real world of addiction treatment has remained more limited, with large numbers of patients still not receiving evidence-based treatments. Along with genetics, another contributing factor to the risk of addiction is one’s psychological composition. Some individuals may be more affected by the rewarding effects of drugs of abuse because they are trying their best to regulate painful emotions. Importantly, policy may be informed across addictive behaviors in a manner that benefits from effective interventions in other domains. For example, effective tax strategies that have helped curtail tobacco use particularly amongst adolescents and young adults may be used to model similar efforts with respect to food taxation [31, 206].
