A Study Reveals How Internet Addiction in Adolescents Can Impact Brain Function
Individuals who struggle with internet addiction may face a range of issues, including physical pain, mental health challenges, and disrupted sleep.
Researchers have discovered that internet addiction (IA) among adolescents can impact the neural networks in the brain, leading to changes in behavior and development.
According to UCL researchers, adolescents with IA may exhibit alterations in behavior related to physical coordination, cognitive abilities, and mental well-being.
The study defines IA as the inability to resist the urge to use the internet, negatively impacting an individual’s psychological health, as well as their social, academic, and professional life.
The study highlighted potential consequences such as severe physical discomfort, carpal tunnel syndrome, dry eyes, irregular eating habits, and sleep disturbances.
Functional magnetic resonance imaging (fMRI) scans of participants with IA showed decreased functional connectivity in the brain when engaged in active thinking tasks. While at rest, a mix of increased and decreased brain activity was observed.
Researchers emphasized the importance of recognizing early signs of IA in adolescents to manage screen time and impulsive behaviors, reducing the risks associated with addiction.
Handling Internet Addiction
Lead author Max Chang stated that adolescence is a critical period of development where individuals may be susceptible to internet addiction-related urges, impacting their behavior and development.
Mr. Chang highlighted potential negative outcomes such as difficulties in maintaining relationships, engaging in social activities, dishonesty about online behaviors, and disruptions in eating and sleep patterns.
Senior author Irene Lee acknowledged the benefits of the internet but warned about its potential negative effects on daily life.
Ms. Lee advised young people to set reasonable limits on internet use, be aware of the psychological and social implications of excessive online time, and enforce sensible usage patterns.
Widespread Issue
UK Addiction Treatment Centres (UKAT) identified that young individuals are at higher risk of experiencing IA, with a significant percentage incorporating internet use into daily activities.
According to UKAT, compulsive internet use can alter brain function, heightening the gratification associated with online activities due to the release of dopamine triggered by notifications.
Ofcom reported that the majority of people in the UK had access to home internet in 2022, with popular platforms for teenagers including YouTube, Instagram, TikTok, and Snapchat.
Further research on the effects of IA on functional connectivity changes in adolescents is necessary for a deeper understanding of the issue, with UCL authors urging future studies to include larger sample sizes and diverse populations.
