Key Takeaways

1. Myasthenia gravis occurs when the immune system attacks acetylcholine receptors at the neuromuscular junction, disrupting the signal between nerves and muscles

2. Fatigable weakness is the hallmark symptom — patients may feel fine in the morning and experience drooping eyelids, double vision, or slurred speech by afternoon

3. MG is not primarily genetic; it can develop at any age and affects both men and women across a wide age range

4. Early symptoms are frequently mistaken for aging, deconditioning, or even intoxication, delaying diagnosis by a year or more

5. Treatment has evolved dramatically — from steroids alone to tailored therapies including FcRn inhibitors, complement inhibitors, B cell therapy, and thymectomy

6. Hospitalization rates for myasthenic crisis have dropped significantly with modern treatment options
