The effectiveness of non-invasive vagus nerve stimulation in migraine management: a meta-analysis of randomized controlled trials.

Non-invasive vagus nerve stimulation (nVNS) is a new treatment for migraines. This research reviewed several studies to see how effective nVNS is. Researchers looked at its effects on headache days and pain intensity. They gathered data from various medical databases to find relevant studies. The analysis included randomized controlled trials, which are considered high-quality research. Results showed that nVNS can reduce the number of headache days. It also helps lower the need for acute medication. Patients reported improvements in headache pain intensity as well. The overall findings suggest that nVNS is a promising option for migraine management. This treatment could benefit those who do not respond well to medications. More research is needed to confirm these results and understand how nVNS works. Overall, nVNS may offer a new path for migraine sufferers seeking relief. Clinical relevance: This research suggests that non-invasive vagus nerve stimulation could be an effective treatment option for patients with migraines, potentially reducing headache frequency and reliance on medications.
