Gambling definition marked by the alpha

Postby Meziktilar В» 03.02.2020

.

For many, gambling is a recreational activity that is performed periodically without ill effects, but for some, gambling may interfere with life functioning. A diagnostic entity, pathological gambling, is currently used to define a condition marked by excessive and problematic gambling.

In this review, the current status of understanding of the neurobiologies of gambling and pathological gambling is described. Multiple neurotransmitter systems norepinephrine, serotonin, dopamine, opioid and glutamate and brain regions ventral striatum, ventromedial prefrontal cortex, insula, among others have been implicated in gambling and pathological gambling.

Considerations for future directions in gambling research, with a view towards translating neurobiological advances into more effective prevention and treatment strategies, are discussed. Gambling, defined as placing something of value at risk in the hopes of gaining something of greater value, is a widely prevalent behavior that has been popular for millennia. Those with more severe gambling problems may meet criteria for pathological gambling PG , a diagnostic entity introduced in the Diagnostic and Statistical Manual DSM in [ 1 ].

For comparison, a diagnosis of a substance-use disorder in DSM-5 may require meeting 2 or more inclusionary criteria. This proposed reclassification is based on data from epidemiological, clinical and neurobiological domains [ 3 , 4 ]. Given the recently proposed changes to PG, this article will review the neurobiology of gambling and PG within the context of this changing landscape and will discuss future directions for research, with a view towards translating improved neurobiological understandings into better prevention and treatment strategies.

Here, we will summarize main findings from neurochemical and neural research of PG and subsyndromal gambling, using the tables to provide detailed information, and consider future directions. Multiple neurochemical systems have been implicated in gambling and PG Table 1. Data exist consistent with these proposed roles see Table 1 , although there appears to be a more complex relationship e.

As such, there exists significant need for translating information about the neurobiological underpinnings of PG into treatment advances. Multiple cognitive processes have been linked to propensities to gamble and to the severity of gambling problems Table 2. Although individuals with PG often score within normal range on intelligence tests and may show fewer cognitive deficits as compared to individuals with substance addictions [ 10 ], they often score highly on measures of impulsiveness and low on measures of self-control [ 6 ].

Additional behavioral measures e. Much of this literature supports relatively diminished activation of the prefrontal cortex particularly ventromedial but also ventrolateral and orbitofrontal and subcortical regions particularly the ventral striatum Table 2. However, reports of relatively increased activation exist, particularly in response to gambling cues, although the findings are not uniform across studies Table 2. In addition to the regional brain activation findings tabulated, preliminary data have identified regions of poorer white matter integrity in PG, with poorer integrity linked to behavioral tendencies in PG e.

These findings suggest that brain circuits, particularly those involving ventral prefrontal, ventral striatal and limbic regions, may contribute importantly to reward-related decision-making that drive gambling behaviors and underlie PG.

Different thresholds have been proposed, ranging from non-gambling to PG Figure 1 [ 13 ]. Different thresholds for defining groups based on problem-gambling severity have been identified using data-driven methodologies e. Data also indicate that people transition through different stages based on levels of problem-gambling severity [ 17 ], although the factors that promote transitions from lesser to greater levels of problem-gambling severity or vice-versa are not well understood and represent an important and needed area of investigation.

Schematically diagrammed are different stages of problem-gambling severity ranging from non-gambling to pathological gambling. Many factors likely influence decisions not to gamble as well as the nature and extent of gambling, including participation in specific levels of gambling falling along a spectrum of problem-gambling severity pictured on top. Domains of factors with specific examples of factors within each domain are provided pictured on bottom.

Domains may operate in main or interactive manners indicated by a main bidirectional arrow that contains within it multiple bi-directional arrows , and may do so in ways that vary across development. Domains may influence any of the identified severity levels or stages, as schematized with the multiple bi-directional arrows.

Multiple factors likely influence these transitions. Life experiences may also influence transitions in both detrimental and protective fashions. For example, resiliency factors may include being married, having strong social networks, being more educated, having larger incomes, participating in religious services utilizing protective cognitive and behavioral strategies [ 19 ].

On the other hand, risk factors may include trauma and stress including early childhood adversity , early exposure to and initiation in gambling, truant or delinquent behaviors, impulsive tendencies, substance-use behaviors, and other psychiatric or medical conditions [ 19 - 21 ].

These factors may also interact in important manners. Commonly occurring allelic variants may demonstrate clinically relevant interactions with environmental factors to confer risk or protection in manners that could influence gambling transitions. For example, the gene coding for the serotonin transporter SLC6A4 has commonly occurring short and long variations in the promoter region that lead to differential protein expression and are associated with different patterns of amygdala responsiveness and vulnerability to depression based on childhood maltreatment [ 23 , 24 ].

The identification of specific epigenetic factors underlying such vulnerability and resilience and the extent to which such factors may influence gambling transitions and trajectories warrant direct investigation. In order to investigate such phenomena more precisely, a better understanding of the genetic underpinnings of gambling and PG is warranted.

Multiple constructs e. Specific aspects of impulsivity e. These constructs may also be sensitive to environmental factors e.

Impulsivity-related constructs may be multi-faceted and associate in specific fashions with gambling transitions and trajectories at different developmental epochs [ 22 ].

As temperamental and related behavioral characteristics at early ages have been linked prospectively to multiple behaviors and phenomena substance use, academic performance, and brain responses [ 27 ], the extent to which such factors relate to gambling behaviors should be examined directly as such factors may influence prevention and policy efforts e.

Integrating neuroimaging measures into randomized clinical trials offers the opportunity to understand the mechanisms underlying effective treatments and their active ingredients. Such data could provide a stronger foundation for modifying and adapting therapies or combinations thereof in order to improve their efficacies.

Further research is needed to examine these hypotheses and to translate the findings into improved treatments. As an increasingly large and diverse array of biotechnologies permit the acquisition of data from multiple domains, it is increasingly important to gather and synthesize information from multiple areas in order to understand gambling behaviors. Arguably, this work has progressed further in understanding non-gambling conditions e.

Important areas to consider include the integration of genetic and neuroimaging measures and the concurrent and integrative use of multiple imaging modalities e. Critically important in this work is the inclusion of careful phenotypic assessments diagnostic, behavioral, and self-report that can be linked to imaging measures in order to understand how individual differences might relate to biological measures underlying gambling behaviors. Advanced analytical techniques also deserve attention, particularly those that consider connectivity or identify brain circuitry.

The identification of circuitry relating specifically and perhaps differentially to pathology and treatment outcome should improve our understanding of treatment mechanisms and lead to better therapies.

Translational efforts involving animal models of gambling behaviors have only begun to be examined in gambling. Rat models examining near-miss and gambling task phenomena have been developed and used to examine neurochemical contributions to these processes [ 31 , 32 ].

Given advances in targeted gene expression in rodents [ 33 ], such techniques may help better understand how specific molecular entities within specific cells and neuronal circuits influence gambling behaviors. As animal research permits alternative and complementary avenues of investigation, it should help promote a better understanding of the pathophysiology of PG and identify novel targets for treatment development.

Using neuroscience to influence policy remains a goal for gambling. While specific avenues of research have direct policy implications e. While the past decade has witnessed a significant advance in our understanding of the neurobiology of gambling and PG, there remain many poorly understood aspects.

Important gaps exist with respect to integrating information from multiple domains and understanding how specific factors relate perhaps in interactive fashions to gambling transitions and trajectories across the lifespan. While empirically validated treatments for PG have varying degrees of support, little is known about their mechanisms of action or how specific therapies might work better for specific individuals. Generating improved prevention, treatment and policy efforts from a better understanding of the neurobiology of gambling and PG seems an attainable future goal.
