To investigate the opinions of physicians about brain surgery for drug-resistant epilepsy worldwide.Practicing neurologists, psychiatrists, and neurosurgeons from around the world were invited to participate in an online survey. The survey anonymously collected data about demographics, years in clinical practice, discipline, nation, work setting, and answers to the questions about beliefs and attitudes about brain surgery for drug-resistant epilepsy.In total, 1410 physicians from 20 countries and different world regions participated. The propensity to discuss brain surgery with patients, who have drug-resistant seizures, was higher among men (versus women) [Odds Ratio (OR) 1.67, 95% CI 1.20-2.31; p = 0.002]. In comparison to neurologists, psychiatrists were less likely (OR 0.28, 95% CI 0.17-0.47; p 0.001) and neurosurgeons were more likely (OR 2.00, 95% CI 1.08-3.72; p = 0.028) to discuss about it. Survey participants working in Africa, Asia, the Middle East, and the Former Union of Soviet Socialist Republics showed a lower propensity to discuss epilepsy surgery with patients.This study showed that on an international level, there is still a knowledge gap concerning epilepsy surgery and much needs to be done to identify and overcome barriers to epilepsy surgery for patients with drug-resistant seizures worldwide.

Purpose We investigated the various possible reasons for uncontrolled seizures in patients 18 years of age and older to determine the impact of pseudointractability. We also tried to investigate the various forms of pseudointractability. Methods In this cross-sectional study, all patients 18 years of age and older with their first seizure occurring at least six months prior to the referral date, taking at least one antiepileptic drug (AED) and having at least one seizure in the past three months were studied. The presumed reason for uncontrolled seizures was arbitrarily considered to be one of these five categories: Poor compliance; Wrong medication (misclassification); Wrong dose of the correct medication; Diagnosis other than epilepsy; and finally, Medically-refractory epilepsy. Statistical analyses were performed using Chi-square and Fisher's Exact tests, and a P value less than 0.05 was considered significant. Results 350 patients were referred to us due to uncontrolled seizures. One hundred ninety-one (55%) were male and 159 (45%) were female. Twelve percent of the patients had diagnoses other than epilepsy, 40% had indeed medically-refractory epilepsy; 29% were taking the wrong AEDs (misclassified epilepsy); 18% were taking suboptimal doses of AEDs; and 1% had poor drug compliance. The most common reason for uncontrolled seizures among patients with idiopathic generalized epilepsy was taking the wrong AED. However, among patients with focal epilepsy, true medically-refractory epilepsy was the most common reason. Conclusion Uncontrolled seizures are a commonly encountered problem, especially at epilepsy clinics and one should consider all possible reasons for these uncontrolled seizures. The mainstay for making a correct diagnosis is a detailed clinical history.
