Myasthenia gravis (MG) is a relatively rare autoimmune disorder in which antibodies form against nicotinic acetylcholine (ACh) postsynaptic receptors at the neuromuscular junction of the skeletal muscles. It is a type II hypersensitivity immune response that results in a characteristic pattern of progressively reduced muscle strength with repeated use and recovery of muscle strength after a period of rest.

The most important aspect of MG in emergency situations is acute worsening of weakness that leads to neuromuscular respiratory failure. The diagnosis of myasthenic versus cholinergic crisis and its management are also significant challenges in emergent settings.

Are you familiar with key aspects of the etiology, epidemiology, presentation, workup, and treatment for this condition? Test your knowledge with this quick quiz.
