The degree of muscle weakness varies tremendously and can range from a localized form limited to eye muscles to a generalized form in which many muscles are affected. The thymus gland, which is part of the immune system, can be abnormal in MG patients or tumors can be developed on the gland. Diagnosis Diagnosing myasthenia gravis can be difficult because muscle weakness is common in many other disorders. In addition to a medical history and physical and neurological examinations, the doctor may ask for other testing. Certain anticholinesterase agents improve neuromuscular transmission.
Immunosuppressive drugs help suppress the production of abnormal antibodies.
Removal of the thymus gland can improve symptoms and, in come cases, cure patients. Other procedures can be helpful during periods of weakness. They include removing abnormal antibodies from the blood and providing the body with normal antibodies from donated blood. A crisis or medical emergency in which the respiratory muscles are effected can be triggered by infection, fever, stress or adverse reaction to medication. This requires immediate attention and the patient may need a respirator.
