Neural Correlates of Smartphone Dependence in Adolescents

Increases in depressive and suicide-related symptoms among United States adolescents have been recently linked to increased use of smartphones. Understanding of the brain mechanisms that underlie the potential smartphone dependence may help develop interventions to address this important problem. In this exploratory study, we investigated the neural mechanisms underlying potential smartphone dependence in a sample of 19 adolescent volunteers who completed self-assessments of their smartphone dependence, depressive symptoms, and sleep problems. All 19 adolescents underwent diffusion MRI that allowed for assessment of white matter structural connectivity within the framework of connectomics. Based on previous literature on the neurobiology of addiction, we hypothesized a disruption of network centrality of three nodes in the mesolimbic network: Nucleus Accumbens, anterior cingulate cortex, and amygdala. Our results showed positive correlations between the node centrality of the right amygdala and self-reported smartphone dependence, between smartphone dependence and sleep problems, and between sleep problems and depressive symptoms. A higher phone dependence was observed in females compared to males. Supported by these results, we propose a model of how smartphone dependence can be linked to aberrations in brain networks, sex, sleep disturbances, and depression in adolescents.

Conclusion: Mitigation of these effects by identifying subjects at risk and promoting dopaminergic homeostasis to help regulate stress-relative hypodopaminergia, attenuate fears, and prevent subsequent unwanted drug and non-drug RDS type addictive behaviors seems prudent.

I picked upTIME Mental Health: A New Understanding a year ago in the grocery store and slowly worked my way through it. I assumed I would race through the magazine and produce a shining review for my readers to enjoy. Then ADHD happened, which is like saying,“And then I breathed”. When I say“slowly”, I refer to the speed at which glaciers raced across the North American continent. Ultimately, I finished, which is the lesson I take away from my tortoise and hare situation. I wasn’t in competition with anybody, except, perhaps, Father Time, but I must admit that I had an assist from COVID–...

Coping with grief after loss can be one of life’s greatest challenges. We all experience loss — whether it’s a death of someone we love, the end of a relationship, decline in health, or a job transition. Loss disrupts the continuity we feel in our lives. And that may throw our emotional balance into turmoil. Sadness, disbelief, anger, and fear can all be part of how we grieve. Or we may even feel detached and numb. We often describe the grieving process as linear, where we move through these emotions in an orderly, sequential fashion that ends in acceptance. But the truth is healing after loss can seem li...

The global novel coronavirus pandemic afflicting everyone is showing mixed signs of activity. In some countries it appears to be easing, while in others it appears to be experiencing a resurgence. It’s not at all clear when the pandemic will end, but it’s unlikely to do so before 2021. What has become increasingly clear is that the toll of the pandemic will impact more than the people who come down with COVID-19. The mental health impact of living with a pandemic is being mostly ignored — for now. But as the deaths continue to rise, we need to pay close attention to the cost of the pandemic’s reperc...

Authors: Mengin A, Allé MC, Rolling J, Ligier F, Schroder C, Lalanne L, Berna F, Jardri R, Vaiva G, Geoffroy PA, Brunault P, Thibaut F, Chevance A, Giersch A Abstract The psychological effects of isolation have already been described in the literature (polar expeditions, submarines, prison). Nevertheless, the scale of confinement implemented during the COVID-19 pandemic is unprecedented. In addition to reviewing the published studies, we need to anticipate the psychological problems that could arise during or at a distance from confinement. We have gone beyond the COVID-19 literature in order to examine the ...

This article aims to propose guidance to ensure mental health care during the SARS-CoV epidemic in France. METHODS: The authors performed a narrative review identifying relevant results in the scientific and medical literature and in local initiatives in France. RESULTS: We identified four types of major vulnerabilities among patients with mental disorders during this pandemic: (1) medical comorbidities that are more frequently found among patients with mental disorders (cardiovascular and pulmonary pathologies, diabetes, obesity, etc.) which are risk factors for severe covid-19 infection; (2) age (the elderly form...
