Overview

Juvenile myoclonic epilepsy is an epilepsy syndrome characterized by myoclonic jerks (quick jerks of the arms or legs), generalized tonic-clonic seizures (GTCSs), and sometimes, absence seizures. The seizures of juvenile myoclonic epilepsy often occur when people first awaken in the morning. Seizures can be triggered by lack of sleep, extreme fatigue, stress, or alcohol consumption. Onset typically occurs around adolesence in otherwise healthy children. The exact cause of juvenile myoclonic epilepsy remains unknown, but genetics likely plays a role.[1][2][3] Although patients usually require lifelong treatment with anticonvulsants, their overall prognosis is generally good.[1][2]
