Weekly Mind Reader: Game Over?

This week’s edition of Weekly Mind Reader starts with a review of the latest internet gaming disorder research, a case report of tapentadol-induced hallucinations, and how a TV show can help identify face blindness.

Understanding Internet Gaming Disorder and Its Impact on Mental Health

With the internet’s global reach, digital gaming has invaded nearly every part of human interaction, making its mark on psychological and social development.

Early research already established a link between play and psychological well-being. It’s also highlighted how play evolves into rituals and games, turning the most mundane of interactions into compelling adventures. Or something like that.

Although video games date back to the 1950s, they didn’t earn popularity until the emergence of arcades in the 1970s. The PC revolution and broadband internet spurred exponential growth in digital gaming in the ensuing decades. It’s now embedded itself firmly into popular culture. Gamification, which influences behavior through game-like elements, is now prevalent in areas such as corporate productivity, fitness, and education.

Constant technological innovations drive the gaming industry’s growth. But ethical concerns continue to crop up regarding the long-term impact of extending consumerism into the human psyche. Modern games incorporate social interaction through profiles and avatars, transforming solitary experiences into interactive ones. Massively multiplayer online role-playing games (MMORPGs) have pushed economic boundaries, influencing daily life and raising questions about their purpose and design.

Excessive gaming characterizes the phenomenon of Internet Gaming Disorder (IGD), leading to significant impairment or distress. Despite guidelines limiting screen time, the distinction between IGD, social media overuse, and other digital health issues remains blurry. IGD often co-occurs with mental health conditions and substance use disorders, complicating the development of effective treatments.

Epidemiological studies show that IGD affects a notable percentage of adolescents, particularly young men. Scientists attribute this prevalence to societal and physiological factors, with games often designed to be engaging enough to maintain interest without inciting distress. The inclusion of social elements in games like MMORPGs exacerbates IGD, especially among those searching for a social connection.

Neurobiological research indicates that IGD shares similarities with other addictions, such as changes in dopamine transporter density. It also shows reduced gray matter in brain regions tied to impulsivity and cognitive control. These findings underscore the need for validated screening tools and comprehensive mental health assessments to identify and manage IGD more effectively.

Future research should explore the optimal use of gaming in therapeutic contexts, such as for ADHD, and investigate other addiction attributes, such as withdrawal and tolerance. Understanding its effects on different age groups and developing effective interventions remain crucial as gaming expands its reach.
