The emergency physician should be aware of the following issues:
- The differential diagnosis of any patient presenting to the ED with respiratory failure of unknown cause should include neuromuscular respiratory failure
- Complaints of shortness of breath or dysphagia, especially new onset, should be taken very seriously in MG patients
- The clinical features of impending crisis can be subtle, especially in the MG patient with vague symptoms
- The course of MG is difficult to predict
