Brief Summary

Notwithstanding the cumulative evidence on the safety and efficacy of transcranial magnetic stimulation in depression care, the non-response rate to transcranial magnetic stimulation (TMS) amongst treatment-resistant depression has remained substantial despite the health care cost and time incurred. There remains a compelling clinical need to find valid biomarkers to inform personalized treatment. Using supervised machine learning on 4 combined features of neuroimaging markers, our group recently reported excellent prediction for clinical response in 70 patients receiving TMS to left dorsolateral prefrontal cortex for medication-resistant major depression in 2015-18 (Phase 1 study).The clinical utility of these potential neuroimaging biomarkers is still uncertain without further validation of the trained model in an independent clinical cohort.
