This study investigates brain activity in male pathological gamblers (card gamblers) while gambling using a unique computerized card gambling paradigm that emulates actual gambling. The current study endeavored to concurrently explore group differences on factors such as mood states, cognitions, gambling behaviours, personality traits, and neural activity between a subset of pathological gamblers and control participants. A group of 14 predominately card playing male gamblers who met the DSM-IV-TR criteria for Pathological Gambling disorder and 15 infrequent or non-gambling control participants were screened and recruited. Personality characteristics were measured using the Arnett Inventory of Sensation Seeking (AISS), Tridimensional Personality Questionnaire (TPQ) and Conners. Adult Attention Deficit Hyperactivity Disorder Rating Scale-Long version (CAARS-L), while self-report mood and cognition questions were completed before, during, and after the gambling task. Pathological gamblers had significant increases in positive mood, urges to gamble, more irrational beliefs around luck and control, were more novelty-seeking and impulsive and were less likely to bet rationally using the information around risk presented at the time. The neurological findings revealed a complex interplay of activity in response to different aspects of the gambling task. Groups did not differ in regions of the striatum; however, overall group differences emerged in the medial and dorsolateral prefrontal cortex, subthalamic nucleus, insula, cerebellum, lentiform nucleus, and the posterior parietal cortex. Differences occurred in regions of the brain involved in conscious awareness of urges, decision-making in uncertain or risky situations, learning, as well as minimizing losses and ensuring future avoidance of penalties. The group differences that emerged across these factors suggest an intricate interplay of each of these variables in their contribution to the maintenance of gambling problems.
