“…The contrast between the failure of any of these scales to predict relapse and the predictive significance of several behavioural indices is consistent with other evidence of such dissociations in the context of impulsivity and substance use (e.g. McDonald et al, 2003;Reynolds et al, 2006;Verdejo-Garcia et al, 2008). In particular, Krishnan-Sarin likewise found neurocognitive measures of impulsivity to outperform trait measures in predicting relapse to smoking, as did Goudriaan et al (2008) in relation to gambling.…”

Rationale: Neurobiological models of addiction suggest that abnormalities of brain reward circuitry distort salience attribution and inhibitory control processes, which in turn contribute to high relapse rates. Objectives:To determine whether impairments of salience attribution and inhibitory control predict relapse in a pharmacologically unaided attempt at smoking cessation.Methods: 141 smokers were assessed on indices of nicotine consumption / dependence (e.g. the FTND, cigarettes per day, salivary cotinine), and three trait impulsivity measures. After overnight abstinence they completed experimental tests of cue reactivity, attentional bias to smoking cues, response to financial reward, motor impulsiveness, and response inhibition (antisaccades). They then started a quit attempt with follow-up after 7 days, 1 month, and 3 months; abstinence was verified via salivary cotinine levels ≤ 20ng/ml. Results:Relapse rates at each point were 52.5%, 64% and 76.3%. The strongest predictor was pre-cessation salivary cotinine; other smoking / dependence indices did not explain additional outcome variance and neither did trait impulsivity. All experimental indices except responsivity to financial reward significantly predicted one week outcome. Salivary cotinine, attentional bias to smoking cues and antisaccade errors explained unique as well as shared variance. At one and three months, salivary cotinine, motor impulsiveness and cue reactivity were all individually predictive; the effects of salivary cotinine and motor impulsiveness were additive.Conclusions: These data provide some support for the involvement of abnormal cognitive and motivational processes in sustaining smoking dependence and suggest that they might be a focus of interventions, especially in the early stages of cessation.2

“…A major feature common to gambling and substance‐related disorders is impaired impulse control, which may be fundamental to both the development and maintenance of addictive disorders (Bechara 2005; Lawrence et al 2009; Verdejo‐Garcia et al 2008). We have previously shown that Negative Urgency (NU) derived from the UPPS‐P impulsivity scale is related to dopamine D2/3 receptor availability in GD (Clark et al 2012) and also to MOR availability (Mick et al 2015).…”

Evidence for GABA‐A receptor dysregulation in gambling disorder: correlation with impulsivity

et al. 2016

As a behavioural addiction, gambling disorder (GD) provides an opportunity to characterize addictive processes without the potentially confounding effects of chronic excessive drug and alcohol exposure. Impulsivity is an established precursor to such addictive behaviours, and GD is associated with greater impulsivity. There is also evidence of GABAergic dysregulation in substance addiction and in impulsivity. This study therefore investigated GABAA receptor availability in 15 individuals with GD and 19 healthy volunteers (HV) using [11C]Ro15‐4513, a relatively selective α5 benzodiazepine receptor PET tracer and its relationship with impulsivity. We found significantly higher [11C]Ro15‐4513 total distribution volume (VT) in the right hippocampus in the GD group compared with HV. We found higher levels of the ‘Negative Urgency’ construct of impulsivity in GD, and these were positively associated with higher [11C]Ro15‐4513 VT in the amygdala in the GD group; no such significant correlations were evident in the HV group. These results contrast with reduced binding of GABAergic PET ligands described previously in alcohol and opiate addiction and add to growing evidence for distinctions in the neuropharmacology between substance and behavioural addictions. These results provide the first characterization of GABAA receptors in GD with [11C]Ro15‐4513 PET and show greater α5 receptor availability and positive correlations with trait impulsivity. This GABAergic dysregulation is potential target for treatment.

“…Aspects of impulsivity may both predispose to and be exacerbated by addictive behaviors. Impulsivity predicts development of AUDs; is higher in FHPs with more alcohol-dependent relatives (ie higher family-history load); and partially mediates the relationship between FHP and alcohol and substance use disorder (for review, see de Wit, 2009;Dick et al, 2010;Lejuez et al, 2010;Verdejo-Garcia et al, 2008). Other less well-studied impulsivity-related constructs (eg, sensationseeking, risk-taking, compulsivity, behavioural activation/ inhibition, reward/punishment sensitivity) have been related to addiction vulnerability, and addictions therefore warrant consideration (eg, Meda et al, 2009).…”

Individuals family-history positive (FHP) for alcoholism have increased risk for the disorder, which may be mediated by intermediate behavioral traits such as impulsivity. Given the sex differences in the risk for and clinical presentation of addictive disorders, risk for addiction may be differentially mediated by impulsivity within FHP males and females. FHP (N ¼ 28) and family-history negative (FHN, N ¼ 31) healthy, non-substance-abusing adults completed an fMRI Go/No-Go task and were assessed on impulsivity and alcohol use. Effects of family history and sex were investigated as were associations between neural correlates of impulse control and out-ofscanner measures of impulsivity and alcohol use. FHP individuals showed greater activation in the left anterior insula and inferior frontal gyrus during successful inhibitions, an effect that was driven primarily by FHP males. Higher self-reported impulsivity and behavioral discounting impulsivity, but not alcohol use measures, were associated with greater BOLD signal in the region that differentiated the FHP and FHN groups. Impulsivity factors were associated with alcohol use measures across the FHP and FHN groups. These findings are consistent with increased risk for addiction among FHP individuals being conferred through disrupted function within neural systems important for impulse control. Keywords: impulsivity; family history of alcoholism; insula; inferior frontal gyrus (IFG); addiction; sex differences. INTRODUCTIONAlcohol use disorders (AUDs) are prevalent and associated with detrimental health and societal outcomes (Li, 2008). Individuals with a family history of alcoholism (familyhistory positive (FHP)) have increased risk for alcoholism driven by genetic and environmental factors (Lieb et al, 2002;Slutske et al, 2002). Healthy FHPs model addiction vulnerability without confounding effects of excess alcohol on cognition and brain function.Increased AUD risk among FHPs may be conferred via heritable impulsive tendencies (Dick et al, 2010;Tessner and Hill, 2010). Impulsivity is a multi-factorial construct, where distinct sub-components appear to have differential neural bases and relationships with addiction (de Wit, 2009;Lejuez et al, 2010;Rogers et al, 2010). Aspects of impulsivity may both predispose to and be exacerbated by addictive behaviors. Impulsivity predicts development of AUDs; is higher in FHPs with more alcohol-dependent relatives (ie higher family-history load); and partially mediates the relationship between FHP and alcohol and substance use disorder (for review, see de Wit, 2009;Dick et al, 2010;Lejuez et al, 2010;Verdejo-Garcia et al, 2008). Other less well-studied impulsivity-related constructs (eg, sensationseeking, risk-taking, compulsivity, behavioural activation/ inhibition, reward/punishment sensitivity) have been related to addiction vulnerability, and addictions therefore warrant consideration (eg, Meda et al, 2009).Sex differences are important to consider as they are observable for rates, clinical presentation, and health cons...
