Drug Resistant Epilepsy: Current Challenges and the Path Forward

Epilepsy is a tendency of brain to have recurrent unprovoked seizures. Traditionally, the diagnosis of epilepsy has been made after having two unprovoked seizures greater than 24 hours apart. According to recent revised definition by International League Against Epilepsy (ILAE), epilepsy definition includes one unprovoked (or reflex) seizure and a probability of further seizures similar to general recurrence risk (at least 60%).
