Key Takeaway
Consider MST as an alternative to ECT when cognitive preservation is a priority despite potentially lower antidepressant efficacy.

This meta-analysis evaluated the comparative efficacy of magnetic seizure therapy (MST) and electroconvulsive therapy (ECT) in patients with major depressive disorder (MDD). The analysis included a total sample size of 429.

Regarding antidepressant efficacy, MST scores were 0.329 higher than ECT group scores (95% CI: 0.119-0.539, P = 0.0021), indicating inferior performance for MST in primary symptom reduction. However, MST demonstrated significant superiority over ECT across all secondary cognitive outcomes. Specifically, MST performed better in verbal fluency (SMD = 0.75, 95% CI: 0.19-1.31, P = 0.0088), immediate memory (SMD = 0.68, 95% CI: 0.35-1.01, P < 0.0001), delayed memory (SMD = 0.61, 95% CI: 0.28-0.94, P = 0.0003), and verbal learning (SMD = 0.57, 95% CI: 0.18-0.95, P = 0.0037).

The authors note that further research is needed to confirm these findings regarding cognitive preservation. Clinically, MST may be slightly less effective than ECT for treating depression but may offer advantages in terms of cognitive preservation. The results suggest a potential trade-off between rapid symptom reduction and the maintenance of cognitive functions.

How this fits prior evidence

This meta-analysis addresses a gap in comparing non-invasive versus invasive neuromodulation for MDD. While previous evidence highlighted that active VNS increases the likelihood of meaningful improvement in suicidal ideation (OR 1.43) and assertive case management reduces suicidal thoughts, this study specifically compares MST to ECT. It provides evidence that while MST may have lower antidepressant efficacy than ECT, it shows superior outcomes in memory and verbal fluency.

When people struggle with severe depression, doctors often choose between two main types of brain stimulation: electroconvulsive therapy (ECT) and magnetic seizure therapy (MST). While both are used to treat major depressive disorder, patients and doctors often worry about how these treatments might affect memory or the ability to speak clearly.

A review of data from 429 patients shows a trade-off between these two methods. The results show that MST was slightly less effective at reducing depression scores than ECT. However, patients who received MST performed significantly better in several areas involving brain function, including verbal fluency and both immediate and delayed memory.

These findings suggest that while ECT might be more powerful for lifting the weight of depression, MST may offer a distinct advantage in preserving cognitive skills like learning and speech. Because these results come from an early analysis, researchers note that more studies are needed to confirm exactly how much of a difference these outcomes make in daily life.

What this means for you:
MST may be slightly less effective for depression than ECT but shows better results for memory and speech.

Common questions

How does magnetic seizure therapy compare to electroconvulsive therapy for depression?

In a study of 429 patients, magnetic seizure therapy (MST) was found to be slightly less effective than electroconvulsive therapy (ECT) at reducing depression scores. While ECT showed higher efficacy in treating the core symptoms of major depressive disorder, MST performed significantly better in areas involving memory and verbal fluency.

Does magnetic seizure therapy help with memory loss?

The data shows that patients receiving magnetic seizure therapy (MST) performed significantly better than those receiving electroconvulsive therapy (ECT) in several cognitive areas. This includes immediate memory, delayed memory, and verbal learning. These results suggest MST may have advantages for preserving certain brain functions.

Is it safe to use magnetic seizure therapy for depression?

The study did not report specific safety data or side effects for either treatment. Because more research is needed to confirm these findings, you should speak with your doctor to discuss which treatment is safest and most appropriate for your specific needs.

BackgroundMagnetic seizure therapy (MST), as a novel physical therapy technique, has demonstrated significant efficacy in the treatment of depression. Previous systematic reviews and meta-analyses have preliminarily confirmed its clinical value. This study conducts a meta-analysis based on updated randomized controlled trials to evaluate the differences in efficacy between MST and electroconvulsive therapy (ECT) in patients with major depressive disorder (MDD), as well as their effects on cognitive function.MethodsWe conducted a systematic search of PubMed, Embase, the Cochrane Library, Web of Science, Ovid, ProQuest, and CNKI databases for randomized controlled trials published up to March 1, 2026. The selection of studies strictly followed the Cochrane Risk of Bias in Randomized Trials tool, and the meta-analysis was conducted in accordance with the Cochrane Systematic Reviewer’s Manual. Data from 429 patients across 6 studies were included in the quantitative synthesis.ResultsThe results showed that post-treatment depression scale scores in the MST group were 0.329 higher than those in the ECT group (95% CI: 0.119-0.539, I² = 9.4%, P = 0.0021), suggesting that the antidepressant efficacy of MST was inferior to that of ECT. In the neurocognitive subgroup analysis, MST performed significantly better than ECT in verbal fluency (SMD = 0.75, 95% CI: 0.19-1.31, P = 0.0088), immediate memory (SMD = 0.68, 95% CI: 0.35-1.01, P < 0.0001), delayed memory (SMD = 0.61, 95% CI: 0.28-0.94, P = 0.0003), and verbal learning (SMD = 0.57, 95% CI: 0.18-0.95, P = 0.0037).ConclusionsOur evidence-based study conducted a meta-analysis of the antidepressant efficacy of MST and its effects on cognitive function. The evidence from this study suggests that MST may be slightly less effective than ECT in treating depression but may offer advantages in terms of cognitive preservation; further research is needed to confirm these findings.
