OBJECTIVE: The aim of this study was to evaluate the efficacy and tolerability of topiramate (TPM) in juvenile myoclonic epilepsy (JME). METHOD: We assessed seizure control and adverse effects of TPM in 22 patients (18 females) aged 13 to 53 years. Target TPM dosage was up to 200 mg/day. The patients were subdivided into 3 groups: those treated with seizure control plus side effects (n=4); treated with non-controlled seizures (n=15) and with JME newly diagnosed (n=3). RESULTS: Sixteen patients completed the first year of the follow-up. Generalized tonic-clonic seizures were completely controlled in 10 (62.5%); more than 50% of reduction in 4 (25.0%) and less than 50% in 2 (12.5%). Myoclonia were controlled in 11 (68.8%) and persisted in 5 (31.2%) patients. Absence seizures were present in 5 (22.7%) of whom 2 (9.0%) showed more than 50% of seizure reduction while 3 (13.6%) presented worsening. Discontinuations were due to inadequate seizure control and adverse events (N=4), low compliance and loss of follow-up (N=2) and subject choice (N=1). CONCLUSION: TPM showed to be an effective and well-tolerated drug in the treatment of JME. Although frequently observed, TPM side effects were tolerable and the drug could be maintained in the majority of patients.
