Drug resistant epilepsy (DRE) is defined as the persistence of seizures despite at least two syndrome-adapted antiseizure drugs. Patients with DRE may benefit from non-pharmacological therapies in addition to optimizing drug management. Surgery may provide long-term seizure freedom for patients with drug resistant focal epilepsy. Comprehensive care adaptations are crucial for improving quality of life in DRE patients.
Drug resistant epilepsy (DRE) is defined as the persistence of seizures despite at least two syndrome-adapted antiseizure drugs (ASD) used at efficacious daily dose. Despite the increasing number of available ASD, about a third of patients with epilepsy still suffer from drug resistance. Several factors are associated with the risk of evolution to DRE in patients with newly diagnosed epilepsy, including epilepsy onset in the infancy, intellectual disability, symptomatic epilepsy and abnormal neurological exam. Pharmacological management often consists in ASD polytherapy. However, because quality of life is driven by several factors in patients with DRE, including the tolerability of the treatment, ASD management should try to optimize efficacy while anticipating the risks of drug-related adverse events. All patients with DRE should be evaluated at least once in a tertiary epilepsy center, especially to discuss eligibility for non-pharmacological therapies. This is of paramount importance in patients with drug resistant focal epilepsy in whom epilepsy surgery can result in long-term seizure freedom. Vagus nerve stimula-tion, deep brain stimulation or cortical stimulation can also improve seizure control. Lastly, considering the effect of DRE on psychologic status and social integration, comprehensive care adaptations are always needed in order to improve patients' quality of life. Drug resistant epilepsy (DRE) is defined by the International League Against Epilepsy (ILAE) as the persistence of seizures despite at least two syndromeadapted antiseizure drugs (ASD) used at efficacious daily dose.1 According to this definition, the single variable that should be considered is whether or not the patient is seizure-free. In contrast, neither the type of seizures, the seizure frequency
