Neurotrophic factors, impulsivity, and reward in children with internet gaming disorder
Official title: Investigation of the Relationship Between Serum BDNF and GDNF Levels and Impulsivity, Reward/Punishment Sensitivity in Children Diagnosed With Internet Gaming Disorder
Run by Istanbul Saglik Bilimleri University · NCT07590180 · Data updated 2026-11-12
This study tests whether kids aged 10–14 with internet gaming disorder have different levels of brain-derived and glial-derived neurotrophic factors compared with healthy peers.

Is this trial a fit for you?
✓Likely a good fit
Children aged 10–14 diagnosed with IGD by DSM-5 criteria and meeting study eligibility, alongside age- and sex-mimicked healthy controls without neuropsychiatric disorders.
✕Probably not a fit
Some participants may not show differences in neurotrophic factors or may not benefit directly from the findings.

What this trial studies
This cross-sectional case-control study compares serum BDNF and GDNF levels between children with Internet Gaming Disorder and age- and gender-matched healthy controls. It also examines how these neurotrophic factors relate to IGD severity and various behavioral and emotional measures using standardized psychometric tools. Participants and their parents will undergo clinical interviews and provide informed consent, with data collected from May to December 2026 at a psychiatric outpatient setting in Istanbul. The analysis will explore associations between biomarkers and behavioral assessments to understand potential neurobiological underpinnings of IGD in youth.
Why it matters
Potential benefit: If successful, the study could help clarify biological markers linked to IGD and guide future biomarker-informed approaches for assessment or intervention in youth.
How similar studies have gone: Other research has begun to link neurotrophic factors to behavioral conditions, but application to pediatric IGD is novel and exploratory.
