Myasthenia Gravis

Myasthenia Gravis literally means "grave muscular weakness." In its typical form, MG is a chronic autoimmune neuromuscular disorder in which there is a fluctuating weakness of a person's voluntary muscle groups.

There are a number of symptoms for Myasthenia Gravis, including: a drooping eyelid, slurred speech, blurred/double vision, chronic muscle fatigue, difficulty breathing, chewing and swallowing, and weak feeling in arms/legs.

While there is no current cure for Myasthenia Gravis, effective treatments do exist. Among these are medication, thymectomy and plasmapheresis. A thymectomy is the surgical removal of the thymus gland that is found in 10-15% of MG patients. Plasmapheresis (plasma exchange) is another treatment method available - it removes the abnormal antibodies from the plasma of the blood.
