Summary: Dopamine, a well-known neurotransmitter, plays a crucial role in Parkinson's disease and various mental and physical activities. Inflammation is recognized as a risk factor for neuronal malfunctioning and cell death in neurodegenerative diseases. Bilirubin, an endogenous defense, has been found to possess anti-inflammatory activity and prevent dopamine neuron demise. This review aims to understand the links between dopamine, inflammation (specifically TNFa), and bilirubin as an anti-inflammatory and explore strategies to preserve dopamine homeostasis.

Summary: Depression and impulsivity are associated with greater cognitive complaints in individuals with bipolar disorders. The prescription of antipsychotics may weaken the relationship between cognitive complaints and objective cognitive performance. Future studies should consider the potential role of dopamine in modulating metacognitive performance and the systematic control of antipsychotic medication in individuals with severe mental disorders.

Summary: Curiosity is considered important for learning, innovation, and entrepreneurship. This paper explores the link between curiosity and cognitive abilities, particularly in the context of recruitment processes. The study finds that curious individuals tend to have higher levels of science and reading ability in school, but their math ability may be negatively affected. These findings offer cost-effective strategies for employers to identify and recruit curious employees without expensive profiling techniques.

Summary: Gambling disorder is a major public health issue, and it shares similarities with substance use disorders in terms of the role of brain monoamines in addiction susceptibility and outcome. The study used [I-123]FP-CIT SPECT imaging to assess the roles of striatal dopamine transporter binding and extrastriatal serotonin transporter binding in gambling disorder, and found that patients with gambling disorder had higher impulsivity scores and higher binding in the ventromedial prefrontal cortex, likely reflecting serotonin transporter activity.

Summary: Human adolescence is associated with risky and impulsive behavior due to changes in decision-making and emotional regulation. Similar changes are observed in chimpanzees, but it is uncertain if the same cognitive mechanisms are involved. This study compared risky choice, intertemporal choice, and emotional responses in chimpanzees of different ages and found that adolescent chimpanzees were more risk-seeking. However, unlike humans, chimpanzees did not show developmental changes in intertemporal choice. Patterns of cortisol, testosterone, and individual differences in choices and emotions further suggested a dissociation between risk and choice impulsivity. These findings indicate that some, but not all, core features of human adolescent decision-making are shared with chimpanzees.

Summary: The emergence, development, and maintenance of gaming disorder (GD) are influenced by gaming-related, individual, and environmental factors. The co-occurrence of these factors leads to GD, while none of them alone can cause the disorder. This paper aims to discuss these three factors in detail based on recent research findings. Gaming-related factors include online vs. offline videogames, game genres, structural characteristics, game design elements, and monetization techniques. Individual factors include demographic risk factors, personality traits, motivation, comorbid psychopathology, genetic predisposition, and neurobiological processes. Environmental factors include family, early life experiences, peers, school, and the cultural context of esports.

Summary: Gambling Disorder (GD) is a behavioural addiction that leads to high level of clinical distress. The duration of illness varies among patients seeking treatment for GD, and previous studies have shown mixed results regarding the relevance of illness duration in treatment outcomes. This study aimed to evaluate the effect of illness duration in the treatment outcome of different profiles of GD patients. The results showed that strategic gambling and women diagnosed with GD had a higher probability of poor treatment outcomes from the early stages of the disorder. These findings emphasize the importance of intervention for these specific profiles of GD patients to improve treatment outcomes.

Summary: This study examined the relationship between community participation and depression and found that it is influenced by identity disclosure, victimization, and structural stigma. The results showed that community participation indirectly affects depression levels through identity disclosure and victimization. Structural stigma moderates this relationship, particularly for sexual minority men in high-stigma countries. No moderation effect was found for gender minorities.

Summary: This scoping review explored the state of the art on recovery from gaming disorder (GD) and found limited understanding and literature on recovery from GD. Studies primarily described changes in GD in terms of symptom reduction or improvement, with little mention or use of the concept of recovery. The findings suggest a need to promote and integrate the notion of recovery in the field of GD.

Summary: The aim of this study was to explore the psychosocial predictors associated with different co-occurrence patterns of three behavioral addictions among adolescents. A total of 2390 Iranian adolescents participated in an online survey, and four latent classes were identified: non-problematic behavior, problematic gambling, problematic social media use with gaming disorder, and disordered gambling with problematic social media use. Different psychological risk factors were found in the co-occurrence of these addictive behaviors, highlighting the need for specialized prevention and treatment programs.

Summary: The aim of this study was to explore the mental representations of different substance use and potentially addictive behaviors, in order to better understand behavioral addictions. The authors found four distinct mental representations, three predominantly negative (Guilt/Shame/Relief, Addiction/Health, and Procrastination/Boredom) and one predominantly positive (Stress/Relaxation). The distribution of these representations varied across substance use and problem behaviors, indicating meaningful differences in cognitive evaluation processes. The study concludes that real addictions can exist even without psychoactive drugs, suggesting that tolerance for problem behaviors might be better indicated by the perceived amount of time wasted rather than the actual time spent.

Summary: The study examines the roles of perfectionism and reactions to failure in gaming disorder. Parental perfectionism may predispose players to gaming disorder through internalized perfectionism and maladaptive reactions to failure. Hungarian gamers completed a survey measuring perfectionism, reactions to failure in gaming, and gaming disorder. The study found that parental criticism was associated with over-engagement with failure via self-critical perfectionism, and higher parental expectations were associated with disengagement from failure through narcissistic perfectionism. The model explained a substantial proportion of gaming disorder variance, indicating the importance of parental criticism and self-critical perfectionism in ruminative responses to failure in gaming.
