Myasthenia Gravis and Who It Affects
A Summary of Myasthenia Gravis and Who It Affects
Myasthenia gravis affects men and women of all ethnic groups, and although it usually affects women under 40 and men over 60, it can occur at any age.
In neonatal myasthenia, the fetus may acquire immune proteins (antibodies) from a mother who has myasthenia gravis. In most cases of neonatal myasthenia gravis, the condition is temporary, and the child's symptoms usually disappear within two to three months after birth. Although myasthenia gravis is not directly inherited (nor is it contagious), the disease may occur in more than one member of the same family. In rare cases, children may show signs of congenital myasthenia or congenital myasthenic syndrome, which are not autoimmune disorders.
