Summary: This study investigated the impact of impulsive choice, as measured by delay discounting tasks, on treatment outcomes in patients with gambling disorders (GD). The results showed that impulsive choice was associated with GD severity and personality traits, and it also predicted a higher risk of relapses and dropout in different groups of GD patients. The findings highlight the importance of considering impulsive choice in the treatment of GD to improve treatment outcomes.

Summary: Through studies using the Iowa Gambling Task, it is found that patients with Parkinson's disease tend to prefer risky choices, possibly due to difficulties in anticipating negative consequences or insensitivity to punishment. Additionally, dopamine medications may have an impact on patients' decision-making under uncertain conditions.

Summary: This study examines the role of personality, cognitive, and biological components in risky decision-making using the Iowa Gambling Task paradigm. The results suggest that sensation seeking and lack of premeditation significantly predict lower payoff, moderated by gender and age. These findings highlight the importance of replicating this research in different age groups and clinical populations.

Summary: The study found that applying low doses of tDCS to the DLPFC of patients with GD can improve impulsivity, decision-making, and cognitive functioning, potentially effectively improving gambling behavior. It is recommended to further investigate the effects of this protocol in large groups of patients and carefully evaluate the patient's emotional state.

Summary: Oxytocin has been extensively studied for its effects on socio-cognitive and behavioral functions, but limited evidence exists regarding its effects on non-social cognition and decision-making. This study found that intranasal administration of 24 IU oxytocin had detrimental effects on decision-making under low outcome predictability/high ambiguity, leading to riskier performance. In contrast, oxytocin resulted in slightly less risky decisions under high outcome probability/low ambiguity. These findings suggest that oxytocin may influence decision-making in healthy males, depending on contextual information.

Summary: The study demonstrates that chronic exposure to glucocorticoids induces suboptimal decision making in uncertain environments, impairs spatial working memory, and affects motor learning processes. Neurobiological analysis shows that glucocorticoid receptor expression is downregulated in the medial prefrontal cortex of individuals exposed to cortisol, which negatively correlates with their decision making performance.

Summary: The dual theory states that decision-making relies on two systems, the affective system and the executive function (EF), developed during adolescence. This study examined the relationship between decision-making and EF processes in early adolescents and young adults. The results showed that adolescents had lower scores on risky decision-making than young adults, and individuals who made more perseverative errors in measuring EF were more likely to make risky decisions in the later stages of decision-making.

Summary: Impulsivity is a multifaceted construct related to various everyday behaviors and is associated with psychopathological disorders and behavioral problems. One way to measure impulsivity is with the UPPS-P Impulsive Behavior Scale, which investigates five distinct facets. This study explored the relationship between a state measure of negative urgency (post-loss speeding in a gambling task) and a trait measure of negative urgency using the UPPS-P questionnaire. The results showed no correlation between post-loss speeding and trait impulsivity or negative urgency, suggesting that these measures do not capture the same underlying constructs.

Summary: Tourette syndrome (TS) and its comorbidities are associated with risky behavior, but it is unclear if this translates to a general attitude towards risk. This study found that impaired evaluation of risk and ambiguity in TS was not related to TS itself, but rather to the presence of comorbidities.

Summary: This study found that early childhood sleep disturbances are associated with worsening executive functioning trajectories in school-aged children with ASD. Sleep onset is a robust early correlate of behavior regulation in children with ASD, whereas sleep duration is a later childhood correlate. Poor sleep in children with autism may exacerbate difficulties in executive functioning over time.

Summary: Impairments in decision-making under uncertainty are observed in individuals with temporal lobe epilepsy and rats with amygdala damage, impacting their ability to avoid risky options. Stimulation of the basolateral amygdala in rats led to an increase in risk-averse choices and impulsivity among certain individuals. These findings suggest that amygdala activity can influence decision-making processes and promote impulsive behavior.

Summary: Patient-centered health care emphasizes shared decision-making and patient involvement, incorporating both clinical evidence and patient preferences and values. In heart valve disease, shared decision-making can improve post-intervention quality of life, and post-intervention counseling and follow-up are important. Patient information and involvement in decision-making and recording of patient-reported outcome measures should be prioritized in valve interventions.

Summary: Gambling Disorder (GD) is influenced by both genetic and environmental factors. This study investigated the underlying mechanisms of GD severity by examining the interactions between genetic, psychological, socio-demographic, and clinical factors. Pathway analysis revealed that specific genetic variants, in interaction with other biopsychological features, predicted greater severity of GD. These findings highlight the complex interplay between biopsychosocial variables in the development and severity of GD, and provide support for the involvement of genetic variants from the neurotrophic factor family.

Summary: Neuroendocrine alterations in hunger and satiety signaling may contribute to the development and maintenance of compulsive overeating in individuals with binge eating disorder (BED). Studies have shown dysfunctions in hormones involved in both homeostatic and hedonic pathways, with a hyperactivated mechanism promoting hunger and potentially abnormal satiety threshold. However, it remains unclear whether these alterations are specific to BED pathology or are related to an obesogenic pattern due to the inclusion of patients with both BED and obesity. Identifying endophenotypes in BED may lead to new therapeutic targets for aberrant eating behavior.

Summary: Individual differences in obesity are not only explained by metabolic and medical complications, but also by alterations in eating behaviour and psychological processes. The heterogeneity of psychological evidence associated with obesity has made it challenging to determine whether psycho-behavioural phenotypes can enhance treatment outcomes. This narrative review summarizes studies on psycho-behavioural phenotypes associated with obesity, identifying three psychological constructs: reward dependence, cognitive control, and mood and emotion. These findings highlight the complexity of psycho-behavioural features in obesity and emphasize the need to consider them in order to improve treatment outcomes.

Summary: The potential link between bariatric surgery and gambling disorder (GD) has not been studied before, but observations suggest that patients undergoing bariatric surgery may develop GD. Obese, older adults, and women may be more susceptible to developing GD due to higher rates of somatic comorbidities. Further research is needed to understand the factors influencing the development of GD in patients undergoing bariatric surgery and to explore preventive measures.

Summary: This study aims to validate the Spanish version of mYFAS 2.0, analyze the relationships between food addiction and other eating behaviors, sociodemographic variables, and BMI, and test the eating-related variables that account for the variance in food addiction. The results show that mYFAS 2.0 has good validity and reliability in the Spanish population. Food addiction is significantly and positively related to eating styles, binge eating, and bulimia, indicating that these variables can be used to identify individuals at high risk of food addiction.

Summary: Sports betting is increasingly popular, particularly among males with high impulsivity who also tend to have a higher likelihood of developing co-occurring pathologies, such as substance use disorders. However, most studies on sports betting are cross-sectional and have limitations in terms of sample size and representativeness. Future research should focus on prevention strategies to address sport-betting-related gambling disorder and other addictive behaviors in vulnerable individuals.

Summary: This narrative review explored studies that used independent component analysis (ICA) to investigate different brain networks associated with internet gaming disorder (IGD). Most studies identified alterations in the default-mode network, executive-control network, and salience network in individuals with IGD, which may contribute to the development and maintenance of this disorder. However, further research is needed to better understand the specific role of each network in the symptomatology and treatment of IGD.

Summary: This study found differences between patients with gambling disorder (GD) with and without self-reported ADHD symptoms in terms of psychopathology, personality, and treatment outcomes. Patients with self-reported ADHD symptoms were more severe in their GD and experienced more severe relapses following treatment. Therefore, more vigilant follow-up and interventions are needed for patients with this comorbidity.
