Myasthenia Gravis


Myasthenia gravis is a rare autoimmune disorder affecting the neuromuscular junction. It is caused by antibodies that disrupt the signaling between nerves and muscles resulting in weakness and fatigue. Myasthenia gravis commonly affects the eye muscles resulting in ptosis (drooping eyelids) and diplopia (double vision). It can also affect the muscles controlling swallowing, breathing and limb movements.  


Myasthenia gravis can be diagnosed using a combination of neurological examination, electrodiagnostic tests (nerve conduction studies or electromyography) and blood tests for pathogenic antibodies. Most patients diagnosed with myasthenia gravis will require treatment to control their symptoms. Treatment may involve medication that suppresses the immune system. Some patients may go into disease remission, while others may require long-term treatment.
