Neonatal Myasthenia Gravis (NMG) is a temporary condition that affects newborns. This condition arises due to the transfer of maternal antibodies against the acetylcholine receptor from a mother with myasthenia gravis (MG) to her infant. These antibodies cross the placenta and can cause muscle weakness in the neonate. NMG typically resolves within a few weeks to months as the maternal antibodies are cleared from the infant's system.
