BACKGROUND: Myoclonic-Astatic Epilepsy (MAE) usually starts before five years of age and is associated with very frequent seizures and is highly resistant to treatment.
AIM: To investigate the outcome of adjunctive topiramate (TPM) therapy in children with a diagnosis of MAE syndrome.
SUBJECTS AND METHODS: In an outpatient setting, case notes of 27 children who received TPM were retrieved and analysed.
RESULTS: Records of 6 children with MAE, who were experiencing 2-8 atonic seizures daily before starting TPM were studied. Improvement was noted after addition of TPM (mean dose at steady-state 7.4+/-2.5mg/kg/day) to the regimen of 1-3 anti-epileptic drugs they were receiving concurrently. All but one child improved following the titration period: one had 50-80% improvement in the frequency of atonic seizures and three had over 80% improvement. However, one child who showed over 80% improvement and was free of atonic seizures, later developed increased frequency of other seizure types. In one child there was no significant improvement. Improvement has been sustained for over 6 months in three patients and over 4 months in one; three have continued TPM. TPM was stopped in three patients (reduction in seizure control/no improvement).
CONCLUSIONS: This study supports the efficacy of TPM in controlling atonic seizures in MAE and indicates that it should be considered as an add-on drug in the management of this 'difficult-to-treat' epileptic syndrome.
