Myasthenia gravis (MG) is an acquired autoimmune disorder caused by an antibody-mediated blockade of neuromuscular transmission, which results in skeletal muscle weakness and rapid muscle fatigue. This relatively rare autoimmune attack occurs when autoantibodies form against the nicotinic acetylcholine postsynaptic receptors at the neuromuscular junction of skeletal muscles. Although in most cases the chief target of the autoimmune attack is the skeletal muscle nicotinic acetylcholine receptor, other antigenic targets that are components of the neuromuscular junction have also been implicated, and numerous novel treatments are available today for patients. MG is among the most treatable neurologic disorders, and success in treatment depends greatly on severity and rapidity of disease progression at the time that treatment is initiated.
