| Myoclonic seizures are the defining feature and are required for the diagnosis of JME and very rarely can be the only type of seizure present. Typically absence seizures are the first to occur in JME. They usually occur 3 to 5 years before the onset of myoclonic or GTC seizures and can happen as early as 5 to 6 years old. Myoclonic seizures present with short, bilateral jerking motions of the arms and legs that do not cause consciousness to be lost and often occurs 30 minutes to an hour after waking up in the morning. JME is typically triggered by sleep loss, alcohol consumption, | Myoclonic seizures are the defining feature and are required for the diagnosis of JME and very rarely can be the only type of seizure present.
