137 de articoleThis meta-analysis synthesizes functional MRI findings to identify shared and distinct brain activation patterns associated with internet gaming disorder and gambling disorder. The study examines neurobiological mechanisms underlying these behavioral addictions through quantitative analysis of neuroimaging data across multiple studies.
A randomized controlled trial evaluated the Digital Netizen Alliance prevention program in 600 Chinese primary school students using network intervention analysis to identify specific symptom changes. The program was associated with reductions in gaming disorder symptoms including affirmation dependence, craving, impaired control, and social escapism.
This retrospective cohort study analyzed national health data from 2008-2022 in South Korea, finding that substance use disorder (SUD) patients had significantly higher mortality (16.8%) compared to non-SUD individuals (10.9%), with alcohol use disorder accounting for 89.7% of SUD-related deaths. Elevated mortality risk was particularly pronounced among lower-income individuals, those with disabilities, and those with psychiatric comorbidities, with increasing incidence rates observed in women and younger adults.
This qualitative study examines how women with gaming disorder experience stigma and navigate barriers to accessing mental health care. The research provides insights into the gender-specific challenges and social factors affecting treatment engagement for this recognized behavioral addiction.
This systematic review and meta-analysis evaluated the effectiveness of various therapeutic interventions for problematic use of digital technology, including psychological therapies, digital programs, exercise, and multicomponent approaches across 125 studies. Psychological treatments demonstrated strong effects for problematic internet use and smartphone addiction, with digital interventions also showing significant benefits.
This cohort study analyzed commercial insurance claims data from 2016-2020 to compare healthcare costs and resource utilization between individuals with alcohol use disorder (AUD) and matched controls. The research employed propensity score matching and generalized linear models to assess differences in inpatient/outpatient visits, emergency department use, and prescription patterns between groups.
This network analysis study of 169 university students examined how substance-related and behavioral addictions cluster together and relate to psychological factors like impulsivity, depression, anxiety, and stress. Using advanced statistical modeling, researchers identified central mechanisms and bridge symptoms connecting addictive behaviors to internalizing disorders.
This cross-sectional study surveyed 1,284 medical students across Egypt, Sudan, and Libya, finding prevalence rates of 28.82% for problematic internet use, 6.78% for gaming disorder symptoms, and 7.55% for problematic pornography consumption. Results revealed positive associations between behavioral addictions and anxiety/depression, with stress showing complex relationships to different addiction types, and sleep patterns correlating with gaming and pornography use.
This systematic review and meta-analysis evaluated off-label medications (bupropion, SSRIs, methylphenidate) and transcranial direct current stimulation (tDCS) as treatments for internet gaming disorder across 18 studies (687 participants). Findings showed pharmacotherapy, particularly bupropion, was more effective than tDCS, with effects remaining stable over follow-up periods.
This research paper reviews a decade of progress in gaming disorder assessment since its recognition in DSM-5 and ICD-11, arguing that the field should unify existing frameworks rather than create new instruments. The authors emphasize that robust theoretical foundations are essential to distinguish excessive gaming from clinical disorder, and propose combining psychometrically validated self-report measures with objective gaming data for improved assessment.
This systematic review synthesized 30 studies examining cognitive impairments in gambling disorder relative to other psychiatric conditions and comorbidities, rather than only comparing to healthy controls. Results show greatest cognitive impairment in cocaine-dependent individuals and gamblers with comorbid ADHD, followed by those with eating disorders, OCD, and substance dependence, with gamblers lacking comorbidities showing intermediate impairment levels.
This paper proposes a unified spectrum framework for understanding addiction by integrating substance use disorders, behavioral addictions, and food addiction as related conditions sharing common neurobiological mechanisms. The model identifies three key components: negative reinforcement driving compulsive seeking, cue-induced responses mediated by associative learning, and food addiction as an intermediate phenotype bridging substance and behavioral addictions.
This study used network analysis to explore how food addiction co-occurs with behavioral addictions (gaming disorder, compulsive buying-shopping, compulsive sexual behavior) in 209 treatment-seeking patients. Results identified self-directedness and psychopathological distress as key central nodes differentiating patients with versus without food addiction comorbidity.
This study compared metabolomic profiles in serum samples from young adults with alcohol use disorder, internet gaming disorder, and healthy controls using mass spectrometry. Results identified 26 significantly altered metabolites with shared dysregulation in tyrosine metabolism and distinct pathway activation patterns between the two addictive disorders.
This systematic review examined four clinical trials (176 patients with alcohol use disorder) investigating psychoactive tryptamines like dipropyltryptamine and diethyltryptamine as addiction treatments. Results showed abstinence rates ranging from 10-38% at follow-up, with no significant differences compared to control groups and poorly reported adverse effects, indicating limited evidence for efficacy of these compounds in addiction treatment.
This review examines how environmental cues associated with rewards influence behavior across multiple addictive disorders including alcohol use, binge eating, gambling, and internet gaming, focusing on learning mechanisms like Pavlovian conditioning and Pavlovian-to-Instrumental Transfer. The evidence suggests partially overlapping but distinct processes (incentive salience, attention capture, instrumental control modulation) differentially expressed across individuals and disorders rather than a single cue-reactivity mechanism.
This editorial examines the commonalities and distinctions between substance use disorders and behavioral addictions, such as gambling and internet addiction. The analysis contributes to understanding addiction as a spectrum of conditions with shared neurobiological and psychological features despite different triggering agents.
This perspective article examines whether craving—an intense, persistent involuntary desire for a substance or behavior—can serve as a unified diagnostic criterion across both substance and behavioral addictions. The author reviews evidence suggesting craving may represent a common mechanism underlying different addiction types, despite its established role in substance addiction being less formalized in behavioral addiction diagnosis.
