Myasthenia gravis (MG) is a highly treatable disease with many effective treatments and a natural history that continues to improve with better diagnostic tests and effective medications. Diagnosing and treating patients with MG can be very rewarding for any neurologist because most patients can live normal lives with appropriate treatment.

Myasthenia gravis is an autoimmune neuromuscular disease that causes fluctuating weakness of the eyes, medulla, and limbs and can, in 15% of cases, cause myasthenic crisis, a neurological emergency characterized by respiratory failure. Although uncommon, myasthenia gravis requires prompt diagnosis and treatment because the potential for improvement and remission is high. In particular, the diagnosis and treatment of myasthenia gravis in pregnant women and children require special considerations.
