ECT, Neuromodulation and Physical Treatments
Indications, practical delivery, benefits, risks and outcomes of ECT, plus the role and boundaries of DBS, rTMS and psychosurgery.
How to prepare for MRCPsych Paper B
Integrate clinical formulation, safety and current UK practice with disciplined appraisal of design, bias, estimates and applicability.
Core concepts
Concept 1
ECT decisions balance indication, urgency, likely benefit, alternatives, anaesthetic and cognitive risk, consent or capacity, and an individual continuation plan.
Exam cue: For ECT, work through indication, consent or legal authority, pre-treatment assessment, treatment parameters, monitoring and review.
Concept 2
rTMS, deep brain stimulation and psychosurgery differ in invasiveness, evidence, governance and usual clinical role; they are not interchangeable labels for one treatment class.
Exam cue: For neuromodulation, distinguish established use from specialist or research use and match the technique to its risk and governance burden.
Risk pitfalls and guardrails
Reducing an ECT decision to diagnosis alone without severity, urgency, previous response and patient preference.
Guardrail: Do not diagnose from one feature; establish context, course, impairment, exclusions and the classification system in use.
Quoting one cognitive-risk estimate without accounting for technique, course, individual vulnerability and measurement time.
Guardrail: Do not convert a group association or score into certain individual prediction or a stand-alone disposition decision.
Memory anchors
What must precede an ECT course?
A documented indication, alternatives discussion, consent or lawful authority, physical and anaesthetic assessment, and baseline monitoring.
Why review ECT during a course?
To weigh emerging benefit against adverse effects and decide whether parameters, frequency or continuation should change.
What is continuation treatment intended to reduce?
Relapse after a successful acute treatment course.
How does rTMS differ broadly from ECT?
rTMS is non-convulsive and usually does not require general anaesthesia, with different indications and evidence.
Why is governance central to invasive neuromodulation?
Irreversibility or surgical risk, limited indications and uncertain benefit require specialist selection, consent and long-term oversight.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
