Autoimmune myasthenia gravis (MG) occurs in children, as well as in adults. Childhood myasthenia gravis is characterized by its distinct clinical features. Epidemiological studies have shown the high frequency of onset before the age of 5 years in Japan. Similar results have been reported from China. Clinical types are divided into pure ocular, latent generalized and generalized. In general, childhood myasthenia gravis is milder, mainly with ocular symptoms. Anti‐acetylcholine receptor antibody is often negative (seronegative). The responsiveness to treatment is generally good, and almost 90% of patients can achieve complete remission. Early diagnosis and adequate treatments are important.
