AbstractThe prevalence of true drug-resistant epilepsy (DRE) in the general population is about 20%. The International League Against Epilepsy (ILAE) working group defined DRE as the failure of seizure control by adequate trials of two well-tolerated and appropriately selected drugs, either in monotherapy or in combination. DREs can be divided into two broad categories: pseudo drug-resistant (DR) and true DR. Pseudo DRE correspond to those that are incorrectly treated due to patient error, healthcare deficiencies, or physician error or omission. Errors on the part of the patient are irregular compliance with the intake of antiseizure medications (ASMs) such as inadequate time distribution of the ASMs and an unhealthy lifestyle. Healthcare deficiencies are related, for example, to the poor quality of some drugs in patients who stop receiving original drugs and switch to generic drugs. Regarding omissions or errors by physicians, it is important to note that a significant group of patients referred to the clinic as having DRE may have non-epileptic paroxysmal disorders, including functional seizures, errors in the recognition of the type of seizures and epileptic syndromes as well as etiology, and inadequate management of the ASMs and other treatments We consider it essential to systematically study patients with DRE in a multidisciplinary team and we believe that a considerable number of patients will benefit from an early correct diagnosis and adequate comprehensive treatment.
