Drug-resistant epilepsy with uncontrolled severe seizures — despite state-of-the-art medical treatment — continues to be a major problem for up to 30% of patients with epilepsy.
Although drug resistance may fluctuate in the course of treatment, for most patients, drug resistance seems to be continuous.
Unfortunately, traditional antiepileptic drugs (AEDs) don’t seem to prevent or reverse drug resistance in most patients.
However, some new add-on AED therapies have shown as much as 50% in seizure reduction.
