Myasthenia Gravis (MG) is a rare neuromuscular disorder, which weakens
muscles by decreasing number of acetylcholine receptors at the neuromuscular
junction. Symptoms include weakness in the arm and leg
muscles, double vision, and difficulties with speech and chewing. Some
MG patients also experience facial drooping of upper eyelid or muscle
weakness of the face. This can lead to difficulty speaking, difficulty swallowing,
fatigue, or shortness of breath. The disease typically becomes
prominent during adulthood; but symptoms can be observed at any age.
The disease can be detected by physical examination, lab testing, and diagnostic
imaging tests.
