Myasthenia gravis (MG) has been classified into six subgroups : ocular MG (OMG), early–onset MG (EOMG), late–onset MG (LOMG), thymoma–associated MG (TAMG), muscle–specific receptor tyrosine kinase antibody–positive MG (MuSK–MG), and seronegative MG (SNMG). The treatment strategies differ among these subgroups. Based on the Japanese Clinical Guidelines for MG published in 2014, treatment strategies for each subgroup are described and illustrated in the figure. This paper should be a help for physicians taking care of MG patients.
