Comparative Efficacy and Acceptability of Noninvasive Brain Stimulation for Migraine: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.
Brain Behav | 2026
Systematic review / meta-analysisSummary
This network meta-analysis aimed to compare noninvasive brain stimulation techniques for migraine. Researchers searched various databases until October 13, 2025, for randomized controlled trials. The primary outcomes were changes in monthly migraine days and dropout rates. They used a random-effects model for analysis. Data from 28 trials involving 1920 participants were integrated. Among the techniques, visual cortex transcranial direct current stimulation ranked highest for reducing migraine days. This method showed a mean difference of -1.75 in monthly migraine days. For acceptability, transcutaneous occipital nerve stimulation significantly reduced dropout rates compared to sham. The risk ratio for tONS was 0.36. Despite these findings, the evidence quality is mainly moderate-to-low. There was substantial heterogeneity and a sparse network of data. These results require confirmation in larger, standardized trials for better reliability and understanding of effectiveness. Clinical relevance: This research highlights effective noninvasive brain stimulation techniques for improving migraine treatment outcomes.
Key Learning Points
- Visual cortex transcranial direct current stimulation is the most effective noninvasive technique for reducing monthly migraine days, with an average reduction of 1.75 days.
- Transcutaneous occipital nerve stimulation has a lower dropout rate compared to sham treatments, indicating better acceptability for patients.
- The overall quality of evidence supporting these noninvasive techniques is mainly moderate to low, which affects the reliability of the findings.
- There is significant variability in the results across different studies, highlighting the need for caution in interpreting the data.
- Future research should involve larger and more standardized trials to confirm these findings and improve our understanding of noninvasive brain stimulation for migraines.
