Summary
Real-time fMRI neurofeedback (rt-fMRI NF) shows promise for treating internet gaming disorder (IGD). Participants learned to reduce brain activity linked to gaming addiction after just two sessions.
Area of Science:
- Neuroscience
- Psychiatry
- Addiction Research
Background:
- Internet gaming disorder (IGD) is a growing public health concern.
- Current interventions for IGD have limitations.
- Neurofeedback offers a potential novel therapeutic avenue.
Purpose of the Study:
- To investigate the efficacy of real-time functional magnetic resonance imaging neurofeedback (rt-fMRI NF) for individuals at risk of IGD.
- To determine if rt-fMRI NF can train participants to downregulate neural activity associated with gaming addiction.
Main Methods:
- A preregistered, randomized, single-blind trial was conducted.
- Participants with elevated IGD risk underwent two sessions of rt-fMRI NF.
- Training focused on downregulating brain activity in response to gaming cues.
Main Results:
- Participants successfully downregulated brain responses to gaming cues after rt-fMRI NF.
- This downregulation suggests a potential mechanism for therapeutic intervention in IGD.
Conclusions:
- rt-fMRI NF demonstrates preliminary therapeutic potential for internet gaming disorder.
- Further research is warranted to confirm these findings and explore long-term effects.
