Background. Juvenile myoclonic epilepsy (JME) is a classic epileptic syndrome that lacks consensus on the possibility of suspending treatment with antiepileptic drugs (AD).
Method. Retrospective observational study of a series of patients diagnosed with JME with 20 years or more of evolution, focusing on those with withdrawal from AD.
Results. The study involved twenty patients (average age 44.1 years, 55% men) with JME of 30 years average evolution and average age at its outset of 14.2 years. The most frequent type of motor crisis was the combination of myoclonic and tonic-clonic seizures (70%); 60% of the patients have been free of seizures for more than five years. Four patients (20%) were withdrawn from AD, two of them with an average age of 23 years and an average time free of seizures of 7.5 years, who relapsed, and the other two with an average age of 39 years and following 23.5 years free of seizures, who currently have been without seizures for two and nine years.
Conclusions. The possibility of withdrawing AD in patients with JME who have been free of seizures over an extended time seems feasible. We suggest taking into account age at withdrawal and prior existence of a prolonged period of time free of seizures.
