People with
myasthenia gravis often experience very rapid muscle fatigue and weakness, and this is related
only to muscles that are voluntary. When this occurs, there is something going on with the
communication between the nerves and the muscles.
There is no cure for
myasthenia gravis but there are treatments available, such as certain medications, therapy, or
surgery. Some of the common muscles that are affected by myasthenia gravis are the eye muscles,
face and throat muscles, and arm and leg muscles. Symptoms include drooping eyelids, blurred
vision, difficulty speaking or swallowing, and weak arms or legs.
Tests used
to confirm myasthenia gravis are edrophonium tests, blood tests, repetitive nerve stimulation,
EMG, and imaging scans.
