    Juvenile myoclonic epilepsy (JME) is the epilepsy characterized by bilateral upper extremity myoclonic seizures. Myoclonic seizures sometimes involve lower extremities and cause falls, but the status epilepticus in JME is rare. We report a case of JME that experienced myoclonus status epilepticus which was difficult to be differentiated from psychogenic non-epileptic seizure (PNES). Which the patient was 15 years old, he had a tremor after dropping a loaf of bread on his right hand, and since then, he experienced five fits for three years. At first those fits thought to be PNES. However, at the age of 18 years old, the patient had been suffering from the above seizures. However, at the age of 18 years old, he was taken to the emergency room because of the ordinary fit, he was finally diagnosed myoclonic status epilepticus (MSE) after careful observation and recording of EEG during a fit. The importance of recording of EEG during a seizure is recognized.
