About 20 per cent of all affected patients have only ocular myasthenia; the others have some form of generalized weakness. ... Children born of mothers with the disease exhibit a transient weakness that is evident at birth ..., with feeding difficulties manifested by poor sucking and swallowing abilities. ... This condition is called neonatal myasthenia, and is related to circulating antibodies acquired from the mother while the fetus was in utero. Congenital myasthenia is also present at birth, but it may not be evident until after the first year of life. The child produces antibodies against acetylcholine receptor sites and experiences symptoms similar to those presented by myasthenia gravis patients of all ages.
