What is Juvenile Myoclonic Epilepsy (Janz Syndrome)?
Juvenile myoclonic epilepsy (Janz syndrome) is an epilepsy syndrome marked by the presence of absence, myoclonic, and generalized tonic-clonic (GTC) seizures. All patients with JME have myoclonic seizures, 85%-90% of patients have generalized tonic-clonic seizures, and about 20-40% of patients have absence seizures. These often happen when people first wake up in the morning. The exact cause is unknown, but a family history of epilepsy or gene mutations may sometimes be connected to the condition.
Treatment of Juvenile Myoclonic Epilepsy (Janz Syndrome)
Juvenile myoclonic epilepsy (Janz syndrome) is typically well managed with medications for seizures. Most patients don't outgrow their seizures and will need to take medication for the rest of their lives. Getting enough sleep, avoiding alcohol, fatigue and anxiety can help lower the chances of seizures.
