Internet Addiction Alters Brain Chemistry In Young People, Study Finds

An anonymous reader quotes a report from The Guardian: Young people with internet addiction experience changes in their brain chemistry which could lead to more addictive behaviors, research suggests. The study, published in PLOS Mental Health, reviewed previous research using functional magnetic resonance imaging (fMRI) to examine how regions of the brain interact in people with internet addiction. They found that the effects were evident throughout multiple neural networks in the brains of young people, and that there was increased activity in parts of the brain when participants were resting. At the same time, there was an overall decrease in the functional connectivity in parts of the brain involved in active thinking, which is the executive control network of the brain responsible for memory and decision-making. The research found that these changes resulted in addictive behaviors and tendencies in adolescents, as well as behavioral changes linked to mental health, development, intellectual ability and physical coordination. "Adolescence is a crucial developmental stage during which people go through significant changes in their biology, cognition and personalities," said Max Chang, the study's lead author and an MSc student at the UCL Great Ormond Street Institute of Child Health (GOS ICH). "As a result, the brain is particularly vulnerable to internet addiction-related urges during this time, such as compulsive internet usage, cravings towards usage of the mouse or keyboard and consuming media. The findings from our study show that this can lead to potentially negative behavioral and developmental changes that could impact the lives of adolescents. For example, they may struggle to maintain relationships and social activities, lie about online activity and experience irregular eating and disrupted sleep." Chang said he hopes the findings allow early signs of internet addiction to be treated effectively. "Clinicians could potentially prescribe treatment to aim at certain brain regions or suggest psychotherapy or family therapy targeting key symptoms of internet addiction," said Chang. "Importantly, parental education on internet addiction is another possible avenue of prevention from a public health standpoint. Parents who are aware of the early signs and onset of internet addiction will more effectively handle screen time, impulsivity, and minimize the risk factors surrounding internet addiction."
