The World Health Organization (WHO) has added gaming disorder to ICD-11 as a clinical condition associated with distress or interference with personal functioning. This inclusion leads to clinical and public health benefits, such as harmonising terminology, offering clinical landmarks and improving monitoring capabilities and data comparability. Training health professionals to identify and manage gaming disorder is a key challenge for countries. In the present paper we compiled opinions from different countries around the globe on their state of preparedness and needs to tackle this issue. The global views on the topic feed arguments for developing an evidence-based and cross-cultural training tool for gaming disorder management by health professionals.

Biobehavioral features associated with binge-eating disorder (BED) have been investigated; however, few systematic reviews to date have described neuroimaging findings from studies of BED. Emerging functional and structural studies support BED as having unique and overlapping neural features as compared with other disorders. Neuroimaging studies provide evidence linking heightened responses to palatable food cues with prefrontal areas, particularly the orbitofrontal cortex (OFC), with specific relationships to hunger and reward-sensitivity measures. While few studies to date have investigated non-food-cue responses; these suggest a generalized hypofunctioning in frontostriatal areas during reward and inhibitory control processes. Early studies applying neuroimaging to treatment efforts suggest that targeting neural function underlying motivational processes may prove important in the treatment of BED.

Introduction: The characteristics of Asian American and white problem gamblers using a gambling helpline were examined to identify race-related differences.

Methods: Logistic regression analyses were conducted on data obtained from callers to a gambling helpline serving southern New England in 2000–2003, inclusive.

Results: Of the 144 phone calls used in the analyses, 72 were from Asian American callers and 72 were from white callers who were matched on gender, education, income, marital/cohabitation status, and age. Race-related differences were observed in forms of gambling problems, psychiatric problems secondary to gambling, substance use problems, and family history. Asian American gamblers were more likely to report suicide attempts related to gambling and problems with non-strategic gambling. White gamblers were more likely to report both casino and non-casino gambling problems and personal and familial alcohol use problems. High proportions of both groups reported problems with strategic gambling, gambling-related anxiety, family and financial problems secondary to gambling, financial debt, daily tobacco use, and a family history of problem gambling.

Conclusion: Race-related differences should be considered in optimizing prevention and treatment strategies related to problem gambling.

Impulse-control disorders have received relatively little attention from the mental health community. An increasing awareness of the prevalence and impact of these disorders is emerging. Among impulse control disorders, problematic Internet use has been considered and examined. Prevalence estimate studies indicate that problematic Internet use is experienced across geographic locations by many individuals of diverse backgrounds. This review examines problematic Internet use from epidemiological and clinical perspectives. Clinicians should be familiar with the extent of problematic Internet use and the data regarding the efficacies and tolerabilities of available treatments.

Introduction: The objective of the study was to examine gender differences in the relationship between weight group (under-weight to severely obese), and Axis I and Axis II psychopathology.

Methods: Data from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) were analyzed. Logistic regression models examined the past-year likelihood for meeting diagnostic criteria for psychiatric disorders. Interactions between weight group and gender were utilized to determine whether associations were significantly different in men and women after adjusting for demographic characteristics.

Results: First, consistent with previous NESARC analyses, the prevalence estimates of psychiatric disorders were higher among people of higher body mass index groups, regardless of gender. However, these patterns differed across genders. Both severely obese women and men, in comparison to normal weight respondents, were much more likely to meet criteria for affective and anxiety disorders, but these associations were significantly (1.5–2 times) stronger among women. For Axis II disorders, while there were very few associations between personality disorders and weight in men, among women increases in weight group were associated with increases in the likelihood of meeting criteria for a personality disorder.

Conclusion: Weight and psychopathology appear more strongly associated in women than in men. While these data do not allow for identification of underlying mechanisms, they highlight the importance of assessing for psychopathology in overweight and obese patients, and suggest that weight management may be an important consideration in the treatment of psychiatric disorders.

Behavioral addictions, such as pathological gambling, kleptomania, pyromania, compulsive buying, and compulsive sexual behavior, represent significant public health concerns and are associated with high rates of psychiatric comorbidity and mortality. Although research into the biology of these behaviors is still in the early stages, recent advances in the understanding of motivation, reward, and addiction have provided insight into the possible pathophysiology of these disorders. Biochemical, functional neuroimaging, genetic studies, and treatment research have suggested a strong neurobiological link between behavioral addictions and substance use disorders. Given the substantial co-occurrence of these groups of disorders, improved understanding of their relationship has important implications not only for further understanding the neurobiology of both categories of disorders but also for improving prevention and treatment strategies.

Objective: Understanding variations in disease presentation in men and women is clinically important as differences may reflect biological and sociocultural factors and have implications for prevention and treatment strategies. Few empirical investigations have been performed in kleptomania, particularly with respect to gender-related influences.

Methods: From 2001–2007, 95 adult subjects (n = 27 [28.4%] males) with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-defined kleptomania were assessed on sociodemographics and clinical characteristics, including symptom severity, comorbidity, and functional impairment, to identify gender-related differences.

Results: Men and women showed substantial symptom severity and functional impairment. Compared with affected men, women with kleptomania were more likely to be married (47.1% vs 25.9%; P = .039), have a later age at shoplifting onset (20.9 vs 14 years of age; P = .001), steal household items (P <.001), hoard stolen items (P =.020), and have an eating disorder (P = .017) and less likely to steal electronic goods (P < .001) and have another impulse-control disorder (P = .018).

Conclusion: Kleptomania is similarly associated with significant impairment in women and men. Gender-related differences in clinical features and co-occurring disorders suggest that prevention and treatment strategies incorporate gender considerations.

While the etiologies of pervasive developmental disorders (PDDs) appear complicated, multifactorial, and relatively poorly understood research over the last 30 to 40 years has implicated certain neurochemicals in the pathophysiology of these diseases. From these studies, a great deal of evidence has emerged supporting a role for serotonergic dysfunction in individuals with autism and related disorders. Recent clinical trials of drugs influencing serotonergic systems have demonstrated promising effects in children, adolescents, and adults with PDDs.

Impulsivity and compulsivity represent useful conceptualizations that involve dissociable cognitive functions, which are mediated by neuroanatomically and neurochemically distinct components of cortico-subcortical circuitry. The constructs were historically viewed as diametrically opposed, with impulsivity being associated with risk-seeking and compulsivity with harm-avoidance. However, they are increasingly recognized to be linked by shared neuropsychological mechanisms involving dysfunctional inhibition of thoughts and behaviors. In this article, we selectively review new developments in the investigation of the neurocognition of impulsivity and compulsivity in humans, in order to advance our understanding of the pathophysiology of impulsive, compulsive, and addictive disorders and indicate new directions for research.

Redish et al. present a compelling, interdisciplinary, unified framework of addiction. The effort to integrate pathological gambling is especially important, but only the vulnerability of misclassifying situations is described in detail as being linked directly to this disorder. This commentary focuses on further developing the comprehensiveness of this framework for pathological gambling using over-fast discounting as an illustrative example.
