Best treatments for myasthenia gravis

Understanding myasthenia gravis

Myasthenia gravis (MG) is not a disease of the muscle itself but of the handoff between nerve and muscle. MedlinePlus (NLM) describes it as "a chronic (long-lasting) disease that causes weakness in your voluntary muscles," caused by "an error in how nerve signals are sent to muscles" — signals that "get blocked at the nerve-muscle junction." StatPearls (NCBI Bookshelf) calls MG "the most common disorder affecting the neuromuscular junction (NMJ) of the skeletal muscles." The pattern, not the weakness, is the clue. Per MedlinePlus, "This weakness gets worse with activity, and better with rest" — a drooping eyelid, double vision or trouble swallowing that is worst late in the day. StatPearls reports that around 85% of patients have extraocular muscle weakness at initial presentation, and that this progresses to generalized MG in 50% of patients within two years. What people get wrong: a negative antibody test does not rule MG out. StatPearls states anti-AChR antibodies are "present in four-fifths of patients with generalized MG and only in half of the patients with pure ocular MG," with the rest — "about 5% to 10%" — instead showing anti-MuSK antibodies. That is why electrophysiology is used: StatPearls calls single-fiber EMG "the most sensitive among the diagnostic tests for MG." The bedside ice-pack test is narrower than its reputation — StatPearls positions it as what you do "when edrophonium testing is contraindicated," notes it is read as improvement in ptosis, and warns it "cannot be used for the evaluation of extraocular muscles." StatPearls also says chest CT or MRI "should be performed in patients diagnosed with MG to assess for thymoma," because approximately 10% of patients with MG have one. Sudden breathing or swallowing failure (myasthenic crisis) is, in the words of StatPearls, "a medical emergency." This is general information, not medical advice.
