The objective of this systematic review is to evaluate the consistency between definitions of DRE in the literature and the official definition in the International League Against Epilepsy (ILAE) guidelines, and to estimate the incidence, prevalence, and risk factors for DRE. 2020 Aug 3;3(3):245-255. doi: 10.1002/ame2.12131.

Environmental factors, such as trauma and prior drug exposure, and genetic factors that predetermine the rate of absorption, metabolism, and uptake of a drug by target tissue may also uniquely impact an individual and influence their response to AED therapy. NLM Significance: 2008 Jan 1;70(1):54-65. doi: 10.1212/01.wnl.0000286959.22040.6e. Asadi-Pooya AA, Stewart GR, Abrams DJ, Sharan A. The pooled prevalence proportion of DRE among epilepsy patients was 0.30 (95% confidence interval [CI] 0.19-0.42), and the pooled incidence proportion was 0.15 (95% CI 0.11-0.19). HHS An estimation of global volume of surgically treatable epilepsy based on a systematic review and meta-analysis of epilepsy. Plasticity of antiepileptic drug targets. The incidence of refractory epilepsy remains high despite the influx of many new antiepileptic drugs (AEDs) over the past 10 years. One chart review study by Smith and colleagues in England found that 13% of patients referred for refractory epilepsy did not have epilepsy. Treatment resistance is, therefore, a multifaceted phenomenon. Epub 2020 Oct 3.

Pharmacogeneticists are currently attempting to understand the genetic basis of refractory epilepsy so that they can identify subgroups of patients who share a common genetic background and then target drug therapies to meet their specific needs. Lack of consistency in definitions limits the ability to obtain robust estimates on the burden of DRE. If your doctor thinks you have refractoryepilepsy, he or she may suggest that you visit a medical center thatspecializes in epilepsy. 1 Stevelink et al found an unexpectedly high prevalence of refractoriness in JME (35%) based on all seizure types (i.e., absence, myoclonic, and generalized tonic-clonic seizures).  |  USA.gov.

The definition of DRE varied widely across studies, with only 12% meeting the requirements of the ILAE definition. The pooled prevalence proportion of DRE among epilepsy patients was 0.30 (95% confidence interval [CI] 0.19-0.42), and the pooled incidence proportion was 0.15 (95% CI 0.11-0.19). Refractory epilepsy displays three similar categories. In 2015, 1.2% of the US population had active epilepsy (95% CI* = 1.1-1.4). Pharmacokinetic, pharmacodynamic, and neurochemical investigations of lamotrigine-pentylenetetrazole kindled mice to ascertain it as a reliable model for clinical drug-resistant epilepsy.
