Prognosis

Authoring team

The prognosis in myasthenia gravis is very variable. The use of immunosuppressive drugs has steadily improved outcome in recent years.

Remission or substantial improvement can be expected in 80% of patients. For those with associated thymoma, the 5 year survival is approximately 30 %.

Patients with older age of onset and comorbidities, including other associated autoimmune diseases, typically have a poorer prognosis.
