Explaining rTMS vs implants vs ECT for TRD (CASC)

Station instructions (candidate)

You have 7 minutes. Explain why, after several adequate antidepressant failures, rTMS/iTBS is a reasonable next outpatient option: how sessions work (daily weeks; optional shorter iTBS), common side effects (scalp discomfort, headache; rare seizure), need for safety screening, and realistic response rates — not a guaranteed cure. Briefly place VNS (implant, delayed benefit, mixed acute RCT vs longer-term data) and DBS (specialist research; major controlled trials for key targets did not meet primary endpoints) so 'more invasive' is not sold as 'more proven'. Compare with ECT without stigma theatre: ECT remains important for more severe or urgent presentations and for some who do not respond to rTMS. Check understanding; invite questions; offer written information and crisis contacts.[1][2][3][4][5][6]

Marking domains

Empathy and agenda; accurate plain-language TRD rationale; clear rTMS process and AE; no cure promises; honest implant evidence hierarchy; balanced ECT comparison; collaborative plan and safety netting.[1][2][5][6]

Model communication map

1. Open: thank them; check what they already know about magnets/implants/ECT; name shared goals (mood, function, safety).[6]
2. Why now: several proper medicine trials have not controlled depression; outpatient brain stimulation with a magnetic coil (rTMS) has randomised evidence for people in this situation.[1][6]
3. How rTMS works: awake outpatient sessions, usually most weekdays for about 4–6 weeks; we measure a motor threshold to set a safe personal intensity; some clinics use a shorter burst pattern (iTBS) that trials found not worse than standard sessions.[1][2]
4. What he may feel: scalp tapping/discomfort or headache are common and usually settle; seizures are uncommon but we screen risk and stop if one occurs.[1]
5. Implants: a vagus nerve stimulator is surgery with benefits that may build over months; the short sham-controlled study was disappointing on its main measure, while longer observational comparisons look more hopeful — not a quick fix.[3][4] Deep brain electrodes are highly specialised; important controlled trials for major depression targets did not prove clear benefit on primary outcomes — we would only discuss that later at a specialist centre if needed.[5]
6. ECT: not outdated stigma care; for more severe illness (psychosis, catatonia, or when speed is critical) it can still be the most reliable option; modern techniques reduce — not eliminate — cognitive side effects. Choosing rTMS now does not ban future ECT if needed.[6]
7. Close: questions, written info, session logistics, crisis contacts, partner support role, follow-up review of scores.[6]

Common fails

• Guaranteeing permanent cure from rTMS or implants.[1][6]
• Saying DBS is routine and proven after failed tablets.[5]
• Claiming VNS acute sham trial was a clear primary success.[3]
• Dismissing ECT as obsolete or cruel without nuance.[6]
• Skipping safety screen explanation (metal, seizures).[1]
