Episode notes
Appear Competent And Present Clearly
- Appear competent by knowing your kit and practising examinations frequently.
- Start presentations with a one- or two-sentence punchy summary to reassure examiners.
Localise First, Then Use A Simple Sieve
- Isolate the lesion location first (CNS vs PNS vs neuromuscular junction vs muscle).
- Use a simple surgical sieve to prioritise common etiologies once location is identified.
Explain The Pathophysiology Concisely
- Myasthenia gravis is usually antibody-mediated against post-synaptic nicotinic ACh receptors.
- Explain that antibodies cause complement deposition, receptor internalisation and eventual synaptic failure.
