Internet Gaming Disorder

Research and knowledge regarding the neurobiology of behavioral addictions and Internet Gaming Disorder (IGD) remain limited compared to substance and alcohol use disorders. However, IGD is increasingly causing significant functional impairment, particularly in the child and adolescent population. The primary objective of this study is to measure the serum levels of Brain-Derived Neurotrophic Factor (BDNF) and Glial-Derived Neurotrophic Factor (GDNF)-both known for their roles in neurogenesis and neuroprotective effects-in a patient group aged 10-14 and a healthy control group. Additionally, this study aims to investigate the relationship between these neurotrophic factor levels and disease severity, as well as various behavioral and emotional parameters measured through psychometric assessments, to identify differences between the patient and healthy populations. Researchers will compare IGD patient group with healthy control group, both aged 10-14. Participants and their parents will be asked to fill self-report measures and serum samples of participants will be collected for BDNF and GDNF level measurements. The main questions of the study are: * Is there a difference in serum BDNF and GDNF levels between IGD patient group and healthy controls? * Is there a relation between serum BDNF and GDNF levels and IGD severity? * Is there a difference in impulsivity, reward/punishment sensitivity between IGD patient group and healthy controls * Is there a relation between serum BDNF and GDNF levels and impulsivity, reward/punishment sensitivity scores in IGD patient group?

For most people, gaming is perceived as a positive activity. In some cases, however, gaming may turn into an addiction with consequences for the individual health, quality of life and everyday life. Today, there is a lack of evidence-based interventions to treat this condition, called Gaming Disorder (GD). This study will evaluate a new manual for treatment of GD, divided into a number of modules and based on cognitive behavioural therapy (CBT). The study is designed as a randomized controlled trial (RCT) and will be conducted at a clinic specialized in the treatment of gambling and gaming addiction. Participants included in the study will be randomized to one of to groups. The intervention group will receive twelve weeks of individual CBT-treatment while participants allocated to the control group will be put on a twelve-week wait-list. The hypothesis is that the manual based CBT treatment will result in a greater reduction in symptoms of criteria for GD.

Internet Gaming Disorder (IGD) involves impaired cognitive control linked to reduced social reward and dACC-DLPFC brain circuit dysfunction. Enhancing social reward may restore this circuit and improve symptoms. This study uses psychological interventions and neuroimaging to explore and treat IGD.

The goal of the study is to investigate the efficacy of a secondary low-intensity stage of change (SoC) and motivational interviewing (MI)-based Chatbot-assisted intervention in reducing digital addictions in adolescents with Internet gaming disorder (IGD) and/or social media addiction (SMA) by conducting a RCT. Hypothesis: The intervention group will show a greater reduction in rates of IGD and/or SMA at post-treatment and 3-month follow-up than the control group. Design and subjects: A two-armed RCT between the intervention group and psycho-educational control group for adolescents aged 10-19 with excessive screen time. Screening, baseline, post-programme, and 3-month follow-up evaluations will be conducted. Participants will: Be randomly assigned to online brief intervention or psycho-educational control Complete questionnaires evaluating 1 ) Primary outcomes (IGD, SMA), 2) Secondary outcomes (sedentary lifestyle, mental distress, quality of life, eHealth literacy) and 3) Mediators/mechanisms (autonomy, competence)

The aim of this project is to compare the effects of the newly discovered parietal cortex (Pz electrode point) with the dorsolateral prefrontal cortex (F3 electrode point), which has been commonly used in previous studies, and to further develop a closed-loop intervention method of real-time tDCS under on-line electroencephalography (EEG-tDCS), so as to realise an individualised diagnosis and treatment for online game addicts. This study is divided into two parts, the first part to explore the effectiveness of the new target, using a randomised group design, using tDCS intervention, the subject population is online game addicts, the sample size is about 120. Participants underwent baseline information collection on the first day of the experiment including: basic demographic information, assessment of internet addiction severity and craving; EEG collection in resting state as well as task state (Game Cue Response Task, Signal Stop Task, Iowa Gambling Task). The tDCS intervention under the game cue response task was conducted on the second and third days of the experiment, divided into four groups (the first and second groups were the true-false stimulation groups with the anode at the trapezius muscle at the base of the right neck and the cathode at the subject\'s central parietal cortex; and the third and fourth groups had the anode at the subject\'s left dorsolateral prefrontal cortex, and the cathode at the trapezius muscle at the base of the right neck), with 20 min of intervention each time and the Game craving level was assessed before and after the intervention. Resting-state and task-state (Game Cue Response Task, Signal Stop Task, Iowa Gambling Task) EEG acquisitions were performed at the end of the intervention.The second part of the EEG-tDCS closed-loop intervention was conducted, using a randomised group design with a sample size of about 60 subjects who are addicted to online games. On the first day of the experiment, baseline information was collected, and a personalised EEG classifier model was built for each subject based on the EEG signals of the game cue response task; on the second and third days of the experiment, EEG-tDCS closed-loop intervention was conducted, divided into true intervention and sham intervention groups, with the true intervention group identifying whether subjects were in an addictive state in real time under the game cue response task, and addictive states were identified by giving real-time short-time short-time short-time short-time short-time short-time short-time intervention at target locations. The real-time short-term tDCS intervention was given at the target location for a total duration of 20 minutes, and the level of game craving was assessed after the intervention; at the end of the intervention, the EEG was collected in the resting state and the task state (game cue response task, signal stopping task, and Iowa gambling task). The two-part experiment followed up subjects with weekly post-intervention versus one-month post-intervention gaming severity assessments, with resting-state and task-state (gaming cue-response task, signal-stopping task, Iowa gambling task) electroencephalogram acquisitions.

This study aims to investigate the intervention effects of navigated repetitive transcranial magnetic stimulation (rTMS) on craving regulation in individuals with internet gaming disorder (IGD). The primary objectives include: (1) examining the impact of navigated rTMS over the dorsolateral prefrontal cortex (DLPFC) on the gaming cravings, and craving regulation capacity; and (2) exploring the potential neural mechanisms by which rTMS over the DLPFC improves craving intensity, and craving regulation ability.

The goal of this clinical trial is to learn how effective a combined therapy of computer-based game and also high-intensity interval training (HIIT) physical exercise to improve the clinical symptoms, executive function and neuroplasticity in teenagers with Internet Gaming Disorder (IGD). Executive function refers to the brain's ability to manage tasks such as planning, problem-solving, and decision-making. BDNF is a protein crucial for brain health and development. Neuroplasticity is the brain's ability to change and adapt throughout life. High-intensity interval training involves short bursts of intense exercise followed by periods of rest or recovery. The main questions it aims to answer are: * How effective are computer-based game and HIIT exercises in reducing addiction symptoms of IGD? * Will computer-based game and HIIT exercise help teens who are addicted to video games to improve their executive function (become more able to plan ahead and meet goals, display self-control and also follow multiple-step directions)? * Do computer-based game and HIIT exercise help brains of teens with IGD to be more able to change and adapt? Researchers will compare the improvement before and after the therapies. Participants will: * Undergo both therapies (computer-based game and HIIT) every week for 7 weeks. Computer-based game will be done 3 times/week and HIIT 2 times/week * fill out forms, interviewed and also have their blood sample taken for a total of three times (before the start of the therapy, during the 4th week of therapy and after the final therapy session on the 7th week)
