A recent study published in Social Psychiatry and Psychiatric Epidemiology explores the connection between excessive screen time and the onset of manic symptoms in adolescents. The research, which follows a rise in mental health issues among U.S. youth, investigates whether screen use could contribute to the development of manic episodes, a core feature of bipolar-spectrum disorder (BSD).
Does Screen Time Cause Manic Episodes?
In the United States, adolescents spend an average of over eight hours each day using screens—nearly double the amount of time before the COVID-19 pandemic. This increase in screen time coincides with a rise in adolescent mental health problems, with about 29% of U.S. youth currently experiencing mental health issues.
While the rise in screen time is linked to various mental health concerns, the relationship between screen time and manic symptoms remains uncertain. Manic symptoms—such as high energy, irritability, impulsivity, and racing thoughts—are characteristic of BSD, a disorder that often manifests in adolescence and can lead to worse prognoses and increased symptom severity if not properly addressed.
The Link Between Problematic Screen Use (PSU) and Mental Health
Problematic screen use (PSU), particularly the type that mirrors addiction—characterized by conflict, relapse, and withdrawal—appears to share some similarities with the hyperresponsiveness seen in individuals with BSD. Just as BSD is associated with heightened reward sensitivity and motivation, PSU also correlates with abnormal reward-seeking behavior. Furthermore, excessive screen use can disrupt sleep patterns, which may contribute to the onset of BSD symptoms. Conversely, manic symptoms might also lead to increased screen use, creating a cyclical pattern.
Previous studies have highlighted a connection between addictive phone use and bipolar disorder in adults. However, more research is needed to understand how this relationship might play out in adolescents, especially in terms of screen use contributing to manic episodes or vice versa.
Study Overview and Methodology
The study used data from the Adolescent Brain Cognitive Development (ABCD) Study, which included 9,243 participants between the ages of 10 and 11. The study assessed six types of screen use: television, video games, texting, watching videos, video chatting, and social media. Participants provided self-reported data about their screen usage during the first year of the study.
Key Findings
The study found a significant correlation between increased screen time and an elevated risk of manic symptoms one year later. This association was observed across all screen activities, with texting, social media, and video games being the most strongly correlated with manic symptoms, even after adjusting for potential confounding factors.
In fact, problematic social media use accounted for 48% of the increased risk of manic symptoms, while video game use contributed to 58% of the risk. Additionally, sleep duration in the second year of the study accounted for 9% of the risk.
Potential Mechanisms Behind the Link
The study suggests that the instant gratification and reward-based nature of screen engagement—particularly with social media and video games—could be driving this link. Both types of screen use trigger dopamine release in the brain, a neurotransmitter closely associated with pleasure and reward. Elevated dopamine levels are also a hallmark of manic episodes, suggesting a potential shared mechanism between screen use and the development of manic symptoms.
Furthermore, poor sleep habits, which are often linked to excessive screen time, can exacerbate manic symptoms by overstimulating reward circuits in the brain, intensifying the effects of mania.
Implications for Adolescent Mental Health
The study’s findings suggest that reducing screen time, particularly social media use and video gaming, could serve as a preventive measure against manic symptoms and the onset of BSD in adolescents. Early identification of manic symptoms could also help identify individuals who would benefit from early interventions or secondary prevention strategies.
The research highlights the importance of promoting healthier screen habits among young adolescents. Previous studies have shown that digital literacy programs, which educate children on the potential risks of excessive screen time, can lead to healthier behavioral changes, such as reduced screen use and improved mental well-being.
Conclusion
As screen time continues to rise among adolescents, the potential link between excessive use and mental health concerns, including manic symptoms and the development of BSD, requires closer attention. This study underscores the need for targeted interventions to prevent unhealthy screen habits, promote mental resilience, and encourage better sleep practices in young people.
