Study Arms (1)

Topiramate

EXPERIMENTAL

For children: Children will start on topiramate with a dosage of 0.5mg/kg in the evening, followed by 0.5mg/kg/day weekly increments until an initial target dose of 3mg/kg/day is reached. The total daily topiramate dose for children may, not exceed 9mg/kg/day. For adult patients: Adult patients start on topiramate with a dosage of 25mg/day in the evening, followed by weekly increments of 25 mg/day until an initial target dose of 100mg/day is reached. The dose of topiramate may be increased to the optimal dose with weekly increments of 0.5mg/kg/day and of 25 mg/day for children and adults, respectively at the discretion of the investigator.

Drug: Topiramate

Interventions

The patients will receive topiramate tablet twice daily orally up to 16 weeks.
