Coexistence of MG and epilepsy seems not simply due to chance association. MG was not infrequently considered as a complication of long-term anticonvulsant therapy. In National Taiwan University Hospital, we found 4 out of 251 MG patients who suffered from epilepsy. MG manifestations of these patients did not differ from those in MG patients without epilepsy. There were increased levels of anti-body to acetylcholine receptors and association with thymus hyperplasia or thyroid disease. In the literature, we found 25 reported cases with MG and epilepsy. No specific type of epilepsy was linked to coexistence of MG and epilepsy. Possible causes for MG in association with epilepsy are multiple, including drug-induced depression at the neuromuscular junction, anticonvulsant-related immunological changes, and unknown common mechanism to both diseases.[SDGs]SDG3anticonvulsive agent; cholinergic receptor antibody; phenobarbital; phenytoin; primidone; adult; article; depression; disease association; epilepsy; female; human; incidence; major clinical study; male; myasthenia gravis; neuromuscular junction disorder; seizure; thymus hyperplasia; thyroid diseasejournal article2-s2.0-0348142195
