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.
