Abstract

Magnetic seizure therapy (MST) is a novel neurotherapeutic intervention in development for the treatment of major affective disorders. Like other neurotherapeutic strategies such as electroconvulsive therapy (ECT) or transcranial magnetic stimulation (TMS), a primary interest will be to monitor the associated neurocognitive effects. Thus, the purpose of this systematic review was to synthesize the available data on the neurocognitive effects of MST. The authors performed two independent literature searches with the following terms terms: MST, magnetic, magnetic seizure therapy, depression, neurocognition, cognitive, preclinical. We included in this review a total of eleven articles that mentioned MST and neurocognition in the abstract. The articles were divided into three methodological domains that included virtual computer simulations, preclinical studies, and clinical investigations. Collectively, the available evidence suggests MST has little to no adverse cognitive effects. Specifically, virtual computer simulations found the magnetic field was localized to grey matter, and preclinical studies found no neurocortical or neurocognitive sequelae. Clinical investigations found MST to be associated with rapid reorientation and intact anterograde and retrograde memory. Future investigations using translational methods are warranted to confirm these findings and to further determine the effects of MST on neurocognitive functions.

  • In unipolar depression, research to date shows MST is cognitively safe and has a better cognitive safety profile than all standard ECT delivery methods.

    “In unipolar depression, research to date has demonstrated that MST is cognitively safe, and relative to all standard methods of ECT delivery has a superior cognitive safety profile.17,20”

    From Magnetic seizure therapy is efficacious and well tolerated for treatment-resistant bipolar depression: An open-label clinical trial (2020) · cites this paper as [20]

    The Summary of findings and discussion (page unavailable) concludes that the available studies found MST cognitively safe. Clinical study findings (page unavailable) report better overall neurocognitive performance and faster reorientation after MST than after ECT. The review does not establish a superior cognitive safety profile relative to every standard ECT delivery method; it also calls for further research to confirm and characterize MST’s cognitive effects. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • MST shows robust antidepressant effects with shorter reorientation times (≈4-9 min) and fewer cognitive adverse effects than ECT.

    “Across studies, MST shows robust antidepressant effects with shorter reorientation times (≈4–9 min) and fewer cognitive adverse effects [132,133,134,135,136,137,138].”

    From The Heart’s Electromagnetic Field in Emotions, Empathy and Human Connection: Biosensor-Derived Insights into Heart–Brain Axis Mechanisms and a Basis for Novel BioMagnetoTherapies (2026) · cites this paper as [133]

    The Clinical study findings (page not provided) report MST reorientation averages of 5 and 7 minutes, shorter than ECT, and generally better cognitive-test performance after MST. They also report remission in one patient, but do not establish robust antidepressant effects across studies or the stated 4–9-minute range. The Summary of findings and discussion (page not provided) cautions that methodological variability prevents firm neurocognitive conclusions. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Magnetic seizure therapy has been associated with shorter reorientation times and fewer cognitive adverse effects, suggesting it may be cognitively safer and better tolerated than electroconvulsive therapy.

    “As well, MST has been associated with shorter reorientation times and fewer cognitive adverse effects, 20 suggesting that MST may be cognitively safer and better tolerated than ECT.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
