Quick Summary
This study tested whether a specific type of acupuncture called 'mind-regulation electroacupuncture' could help people with ME/CFS who also have anxiety and depression. Researchers used brain imaging to see how the treatment changed activity patterns in the brains of 30 patients compared to 30 healthy people. After 2 weeks of treatment, patients reported less fatigue, anxiety, depression, and sleep problems, and their brain scans showed changes in areas related to emotions and fatigue.
Why It Matters
Understanding how acupuncture may modulate brain network dysfunction in ME/CFS with psychiatric comorbidity could expand treatment options for patients who have limited effective therapies. This study provides neuroimaging evidence that acupuncture affects specific brain regions implicated in fatigue, emotion regulation, and sleep—domains severely disrupted in ME/CFS.
Observed Findings
Patients showed significant reductions in fatigue (all MFI-20 domains except motivation), anxiety, depression, and sleep disturbance scores after electroacupuncture treatment.
Post-treatment ReHo increased in the right precuneus and decreased in the left inferior temporal gyrus and left angular gyrus.
Functional connectivity between the right thalamus and left posterior central gyrus was decreased pre-treatment and partially restored post-treatment.
Brain regions correlated with symptom severity, with temporal, fusiform, and precuneus regions showing associations with fatigue and mood scales.
Inferred Conclusions
Mind-regulation electroacupuncture may alleviate ME/CFS symptoms by modulating abnormal brain regions and restoring emotion-related functional networks.
The thalamus and temporal regions appear to be key neural targets for acupuncture-induced symptom improvement in ME/CFS with comorbid anxiety and depression.
Electroacupuncture may normalize pathologically reduced regional brain activity in patients with ME/CFS.
Remaining Questions
What is the relative contribution of placebo effects versus specific acupuncture mechanisms, given the absence of a sham control group?
Do brain network changes persist beyond the 2-week treatment period, and is repeated treatment necessary to maintain symptom improvement?
What This Study Does Not Prove
This study does not prove that electroacupuncture is an effective ME/CFS treatment because it lacks a sham acupuncture control group, making it impossible to distinguish placebo effects from true physiological effects. The 2-week intervention period is too short to assess durability of benefits or compare efficacy to established treatments. Correlation between brain imaging changes and symptom improvement does not establish causation.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →

How do the effects of mind-regulation electroacupuncture compare to other established or experimental ME/CFS treatments (e.g., cognitive behavioral therapy, graded exercise therapy, or pharmacological interventions)?
Which acupoint combinations are most critical for neuroimaging-detected brain changes, and can this be optimized for individual patients?
