Problem gamblers share deficits in impulsive decision-making with alcohol-dependent individuals.
Open accessAbstract
AIMS: Problem gambling has been proposed to represent a 'behavioural addiction' that may provide key insights into vulnerability mechanisms underlying addiction in brains that are not affected by the damaging effects of drugs. Our aim was to investigate the neurocognitive profile of problem gambling in comparison with alcohol dependence. We reasoned that shared deficits across the two conditions may reflect underlying vulnerability mechanisms, whereas impairments specific to alcohol dependence may reflect cumulative effects of alcohol consumption. DESIGN: Cross-sectional study. SETTING: Out-patient addiction treatment centres and university behavioural testing facilities. PARTICIPANTS: A naturalistic sample of 21 male problem and pathological gamblers, 21 male alcohol-dependent out-patients and 21 healthy male control participants. MEASUREMENTS: Neurocognitive battery assessing decision-making, impulsivity and working memory. FINDINGS: The problem gamblers and alcohol-dependent groups displayed impairments in risky decision-making and cognitive impulsivity relative to controls. Working memory deficits and slowed deliberation times were specific to the alcohol-dependent group. CONCLUSIONS: Gambling and alcohol-dependent groups shared deficits in tasks linked to ventral prefrontal cortical dysfunction. Tasks loading on dorsolateral prefrontal cortex were selectively impaired in the alcohol-dependent group, presumably as a consequence of long-term alcohol use.

Impulsivity is an important characteristic common to behavioral and substance addictions.
“Since impulsivity is an important characteristic common to behavioral and substance addictions (Lawrence et al., 2009; Alvarez-Moya et al., 2011; Kaiser et al., 2012; Jiménez-Murcia et al., 2013; Ochoa et al., 2013; Torres et al., 2013; Di Nicola et al., 2015), heightened levels could also be associated with FA.”

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.
