Summary
Internet gaming disorder (IGD) shows significant sex differences in psychological traits and brain activity. Further research, including animal models, is needed to understand these neurological variations.
Area of Science:
- Neuroscience
- Psychiatry
- Psychology
Background:
- Internet gaming disorder (IGD) is recognized in DSM-5 and ICD-11.
- IGD prevalence and characteristics differ between males and females.
- Limited research has focused on sex-specific aspects of IGD.
Purpose of the Study:
- To review and elucidate sex differences in Internet gaming disorder.
- To analyze psychological features and brain area involvement in IGD based on sex.
Main Methods:
- Selective review of research publications over the past 20 years.
- Analysis of studies evaluating IGD separately for males and females.
- Examination of neuroimaging data, such as fMRI.
Main Results:
- IGD exhibits strong sex dimorphism in psychological features.
- Impulsivity, low self-control, anxiety, emotion dysregulation, and depression show sex differences in IGD.
- IGD is correlated with sex-dimorphic functional characteristics in brain areas.
Conclusions:
- IGD presents distinct psychological and neurological profiles in males and females.
- Sex differences in IGD require further investigation.
- Animal models may aid in understanding the neurological basis of IGD.

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
