Myasthenia gravis is when there is weakness and rapid fatigue in any of the muscles that you can normally control. This condition is caused by a breakdown in the normal communication that occurs between your nerves and muscles.

Symptoms of myasthenia gravis include:

  • Changes in speech, such as your voice sounding very soft or nasal
  • Difficulty swallowing
  • Double vision (diplopia)
  • Drooping of one or both eyelids (ptosis)
  • Frequent choking while eating or drinking
  • Loss of facial expressions
  • Muscle weakness that worsens over time (but usually improves with rest)


Comprehensive Exam - Your doctor will conduct a thorough physical examination– as well as gather a complete health history – to help determine if you have myasthenia gravis. Your doctor will check your reflexes, muscle strength and tone, senses of touch and sights, and your coordination and balance.

Electromyography (EMG) - This test measures the electrical activity between your brain and muscle. Your doctor inserts a tiny wire electrode through your skin and into a muscle to test for electrical impulses.

Imaging - Your doctor may order a computerized tomography (CT) scan or magnetic resonance imaging (MRI) scan to see if you have a tumor or other abnormality that could be causing similar symptoms.


Cholinesterase Inhibitors - These medications can help improve communication between your nerves and muscles, which may help decrease the symptoms of this condition.

Other Medications - Your doctor may prescribe other types of medicine – including corticosteroids or immunosuppressants – to reduce the effects of this condition. While there is no known cure, the symptoms can usually be managed.
