Topiramate in frontal lobe epilepsy.

Background - Frontal lobe epilepsy (FLE) is a type of epilepsy that is difficult to treat and there are few studies about the use of topiramate (TPM). Aim of the study - To evaluate the efficacy and tolerability of TPM monotherapy in FLE. Methods - The study group consisted of 55 (33 male; 22 female) patients. TPM was administered as a first drug (n = 16) or converted after previous treatment (n = 39). All patients were followed every 3 months for at least 1 year. The patients were subdivided into two groups: 'newly diagnosed' patients and 'difficult-to-treat' patients. Results - Overall, all patients completed the 1-year study. At the end of follow-up, 10 patients showed disappearance of seizures and 33 patients showed improvement in seizure frequency. In particular, among the newly diagnosed patients 6/16 patients showed complete cessation of seizures and 5/16 patients showed very good response; in the other group, 4/39 patients showed complete cessation and 4/39 patients showed a very good response. No patients of both groups had worsening of seizures. No treatment-limiting adverse events associated with TPM were reported. Conclusions - TPM is effective in newly diagnosed patients with FLE; TPM can be considered for the treatment of FLE.
