Seizure-freedom reported in 68% of juvenile myoclonic epilepsy patients

Summary:
A 25-year follow-up study reveals that 68% of patients with juvenile myoclonic epilepsy (JME) became seizure-free, with nearly 30% no longer needing antiepileptic drug (AED) treatment.

A 25-year follow-up study reveals that 68% of patients with juvenile myoclonic epilepsy (JME) became seizure-free, with nearly 30% no longer needing antiepileptic drug (AED) treatment. Findings published June 6 in Epilepsia, a journal of the International League Against Epilepsy (ILAE), report that the occurrence of generalized tonic-clonic seizures preceded by bilateral myoclonic seizures, and AED polytherapy significantly predicted poor long-term seizure outcome.

Patients with JME experience "jerking" of the arms, shoulders, and sometimes the legs. Previous evidence suggests that JME is a common type of epilepsy (in up to 11% of people with epilepsy), occurring more frequently in females than in males, and with onset typically in adolescence.. There is still much debate among experts over the long-term outcome of JME, and about which factors predict seizure outcome.

To further investigate JME outcomes and predictive factors, Dr. Felix Schneider and colleagues from the Epilepsy Center at the University of Greifswald in Germany studied data from 12 male and 19 female patients with JME. All participants had a minimum of 25 years follow-up which included review of medical records, and telephone or in-person interviews.

Sixty-eight percent of the 31 JME patients became free of seizures, and 28% discontinued AED treatment due to seizure-freedom. Significant predictors of poor long-term seizure outcome included: occurrence of generalized tonic-clonic seizures (GTCS -- formerly known as grand mal seizures) that affect the entire brain and which are preceded by bilateral myoclonic seizures (abnormal movements on both sides of the body and a regimen of AED polytherapy.

Researchers also determined that remission of GTCS using AED therapy significantly increased the possibility of complete seizure-freedom. However, once AED therapy is discontinued, the occurrence of photoparoxysmal responses (brain discharges in response to brief flashes of light) significantly predicted an increased risk of seizure recurrence.

"Our findings confirm the feasibility of personalized treatment of the individual JME patient," concludes Dr. Schneider. "Life-long AED therapy is not necessarily required in many patients to maintain seizure freedom. Understanding the predictors for successful long-term seizure outcome will aid clinicians in their treatment options for those with JME."
