Abstract

Pathological gambling (PG) is a behavioural addiction associated with elevated impulsivity and suspected dopamine dysregulation. Reduced striatal dopamine D(2)/D(3) receptor availability has been reported in drug addiction, and may constitute a premorbid vulnerability marker for addictive disorders. The aim of the present study was to assess striatal dopamine D(2)/D(3) receptor availability in PG, and its association with trait impulsivity. Males with PG (n=9) and male healthy controls (n=9) underwent [11C]-raclopride positron emission tomography imaging and completed the UPPS-P impulsivity scale. There was no significant difference between groups in striatal dopamine D(2)/D(3) receptor availability, in contrast to previous reports in drug addiction. However, mood-related impulsivity ('Urgency') was negatively correlated with [11C]-raclopride binding potentials in the PG group. The absence of a group difference in striatal dopamine binding implies a distinction between behavioural addictions and drug addictions. Nevertheless, our data indicate heterogeneity in dopamine receptor availability in disordered gambling, such that individuals with high mood-related impulsivity may show differential benefits from dopamine-based medications.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Decreases in D2 receptor binding are not seen in pathological gamblers compared with controls, despite a significant impulsive component.

    “However, it should be noted that decreases in D2 receptor binding are not seen in pathological gamblers compared to control subjects, which also has a significant impulsive component (Boileau et al., 2013; Clark et al., 2012; Joutsa et al., 2012; Linnet et al., 2011).”
  • In two studies of pathological gamblers, low D2 binding correlated with greater impulsivity within the group.

    “Nonetheless, two of these studies (Boileau et al., 2013; Clark et al., 2012) did show that low D2 binding correlated with greater impulsivity within the group of gamblers.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
