What is myasthenia gravis?
MG is a chronic neuromuscular, autoimmune disorder that causes varying degrees of weakness involving the voluntary muscles of the body.  Myasthenia gravis means “grave muscle weakness.” It can affect people of all races and both sexes from infant to senior citizen.  The prevalence rate of patients with MG is estimated to be 20 per 100,000.  MG may affect any voluntary muscle, but most commonly affects those that control eye movements, eyelids, chewing, swallowing, coughing, and facial expression.  Muscles that control breathing and movement of the arms and legs may also be affected. Treatments are available that improve the conditions, but they all have significant side effects.  MG is the best characterized and understood of the autoimmune diseases, however, at present, the cause of MG is unknown, and there is no cure.

This organization has completed the National Health Council’s Standards of Excellence Certification Program and meets the highest standards of accountability, ethical practice, organizational effectiveness, and good public stewardship.
