Exam-exhaustive fellowship reference on rTMS/iTBS, implanted vagus nerve stimulation, and deep brain stimulation for treatment-resistant depression — protocols, safety, landmark trials (O'Reardon, George, THREE-D, SAINT/SNT, Rush VNS, Mayberg/Holtzheimer/Dougherty DBS), evidence ladder versus ECT, and regional access.

Red flags
- Psychotic depression, catatonia, food–fluid refusal, or high-intent suicidality needing rapid reliable response — prefer ECT pathways over elective outpatient rTMS
- Ferromagnetic intracranial metal, cochlear implant incompatibility, or uncontrolled epilepsy — stop and complete device-specific rTMS safety screen before stimulation
- Peri-rTMS clinical seizure — abort session, ABC support, do not 'push through' remaining trains that day
- Selling DBS as routine proven therapy for depression after failed tablets — pivotal SCC and VC/VS sham RCTs failed primary endpoints
- Acute VNS sham RCT negative primary outcome — do not oversell implant as guaranteed rapid antidepressant
- Capacity lost for implant decisions — use jurisdiction-specific substitute decision / mental health law; never invent section numbers
Meet the patient — "doctor, what about that magnet treatment?"
A 42-year-old nurse has run through sertraline, venlafaxine and mirtazapine — adequate dose, adequate duration, genuine adherence, confirmed with her GP and her pharmacist. She is not psychotic, not catatonic, still eating and drinking, no recent attempt, and she goes to work in tears. She hands you a printout on rTMS with one paragraph circled in yellow.[9][12]
Her partner wants ECT "to just fix it"; she wants "the magnet, not the electricity"; the registrar mentions a chest implant "that sends signals up a nerve." Sorting those three asks — without embarrassment, and without promising what the trials do not deliver — is exactly what this topic is for.[9][12]
