Reconsideration of the definition of drug resistant epilepsy / 中华神经科杂志

International League Against Epilepsy published a unified standard for drug resistant epilepsy by numbers of unsuccessful anti-epileptic drugs, criteria for seizure control and follow-up time in 2009. However, there are still some problems and even some controversies in the clinical application of this standard. To provide references for future clinical application and scientific research, we reconsider the definition of drug resistant epilepsy from its historical definitions, core elements and existing problems, and propose that some drug resistant epilepsy patients are probably more appropriately defined as chronic epilepsy.
