Interventions
Eligibility Criteria
You may qualify if:
- History of simple or complex partial epilepsy that has been documented or witnessed
- an electroencephalogram (EEG) during the preceding 5 years that has a pattern consistent with the diagnosis of partial epilepsy
- during an 8-week baseline phase, patient must have at least 8 partial seizures while maintaining therapeutic levels of antiepileptic drugs (AEDs) and have no more than one seizure-free interval of up to 3 weeks
- and no seizure-free interval longer than 3 weeks
- good physical health.
You may not qualify if:
- Patients having solely generalized seizures or lacking documentation of partial epilepsy
- patients with generalized tonic-clonic seizures or other generalized epilepsies in the absence of an EEG consistent with partial epilepsy
- generalized seizures, which are defined by the EEG wave pattern
- seizures that lack an abnormal pulsation pattern on EEG
- females who are pregnant, nursing, or those not using adequate birth control if capable of having children
