Neurotrophic Factors, Impulsivity, and Reward Sensitivity in Children With 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?
