Effect of Computer-Based Game and HIIT Towards Symptoms, Executive Function and Neuroplasticity in Teens with IGD

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)
