Mindfulness Meditation Rewires Brain Circuits, Eases Gaming Disorder and Depression

A randomized clinical trial published in Translational Psychiatry found that mindfulness meditation reduced gaming addiction severity, cravings, and depressive symptoms in adults with internet gaming disorder, while producing measurable shifts in brain circuitry that did not appear in a comparison group assigned to progressive muscle relaxation.

The trial ran from October 1 to November 30, 2023, at Hangzhou Normal University in Hangzhou, China, led by researcher Xuefeng Xu and pre-registered under trial ID ChiCTR2300075869 on September 18, 2023. Participants were adults aged 18 and older who met at least six of the nine DSM-5-TR proposed criteria for internet gaming disorder and who also had comorbid depression. Both the addiction and depression were tracked as target outcomes, since the two conditions frequently occur together.

The trial's published abstract referenced 64 participants in the randomized comparison. A detailed summary of the study reports that 70 patients were initially randomized, with 61 completing the one-month protocol: 34 in the mindfulness meditation group and 27 in the progressive muscle relaxation group. Both groups attended eight training sessions delivered twice weekly, with resting-state fMRI scans taken before and after.

The neuroimaging results give the trial particular weight. Mindfulness meditation was associated with decreased brain activation in the bilateral lentiform nuclei, insula, and medial frontal gyrus, regions the study authors connect to craving responses in gaming disorder. Neural metrics including regional homogeneity and degree centrality tracked these shifts, with coordinated reductions linking changes in mindfulness to decreases in cue-induced craving. The MM group also showed enhanced functional connectivity within the executive control network and along frontostriatal pathways, with additional changes in connectivity between the default mode network and executive-control-related regions.

Progressive muscle relaxation is an active control, not a passive waitlist, which strengthens the case for specificity. PMR participants were engaging in a structured practice at the same frequency, yet IGD severity and craving only decreased in the mindfulness group. That separation points toward the mindfulness component itself driving the changes, not simply the effects of structured activity or clinical attention.

The DSM-5-TR identified internet gaming disorder as a condition warranting more research, and validated treatments remain scarce. The trial concludes that MM was more effective than PMR in decreasing addiction severity and gaming cravings, and findings provide preliminary support for MM as a treatment for IGD while pointing toward frontopallidal pathways as a possible mechanism. Professor Sergey Minaev, an external commentator on the findings, highlighted the non-pharmacological approach's promise for integrated mental health treatment, noting its relevance for addressing both addiction and depression without pharmacological intervention.

The full session-by-session protocols for both mindfulness meditation and progressive muscle relaxation training are documented in the study's eAppendix, offering a reproducible framework for clinicians interested in applying the intervention. With a one-month window and a single-center design, longer follow-up across larger and more diverse samples will determine how durably these brain and behavioral changes hold.
