Lacosamide treatment of juvenile myoclonic epilepsy

Seizure - European Journal of Epilepsy, 02/01/2012

The data from the three patients’ suggest that lacosamide may be effective in the treatment of juvenile myoclonic epilepsy, larger studies are needed to explore efficacy and role of lacosamide in the treatment of this disorder.

  • Juvenile myoclonic epilepsy is the most common form of idiopathic generalized epilepsy with onset at puberty or late teenage years.
  • About 80–90% of patients with juvenile myoclonic epilepsy respond to appropriate antiepileptic treatment and achieve seizure freedom, and about 15% of patients become intractable.
  • Valproic acid, levetiracetam, lamotrigine, topiramate and zonisamide are used as first line or adjunctive therapy of this disorder.
  • Lacosamide is approved for adjunctive treatment of partial onset epilepsies.
  • The role of lacosamide in treatment of idiopathic generalized epilepsy including juvenile myoclonic epilepsy is unknown.
  • The authors present three patients with classic clinical and electrographic features of juvenile myoclonic epilepsy that were maintained on lacosamide (one on monotherapy and two as adjuvant therapy).
  • There were no special pharmacodynamic actions causing exacerbation or worsening of myoclonic jerks or generalized seizures in these three patients.
