A variety of terms, such as “antiepileptic,” “anticonvulsant,” and “antiseizure” have been historically applied to medications for the treatment of seizure disorders. Terminology is important because using terms that do not accurately reflect the action of specific treatments may result in a misunderstanding of their effects and inappropriate use. The present International League Against Epilepsy...
Objective
This study was undertaken to develop a multimodal machine learning (ML) approach for predicting incident depression in adults with epilepsy.
Methods
We randomly selected 200 patients from the Calgary Comprehensive Epilepsy Program registry and linked their registry‐based clinical data to their first‐available clinical electroencephalogram (EEG) and magnetic resonance imaging (MRI) study...
Epilepsy surgery is the treatment of choice for patients with drug‐resistant seizures. A timely evaluation for surgical candidacy can be life‐saving for patients who are identified as appropriate surgical candidates, and may also enhance the care of nonsurgical candidates through improvement in diagnosis, optimization of therapy, and treatment of comorbidities. Yet, referral for surgical evaluations...
Ongoing challenges in diagnosing focal cortical dysplasia (FCD) mandate continuous research and consensus agreement to improve disease definition and classification. An International League Against Epilepsy (ILAE) Task Force (TF) reviewed the FCD classification of 2011 to identify existing gaps and provide a timely update. The following methodology was applied to achieve this goal: a survey of published...
Clinical practice guidelines (CPGs) are statements that provide evidence‐based recommendations aimed at optimizing patient care. However, many other documents are often published as “guidelines” when they are not; these documents, although also important in clinical practice, are usually not systematically produced following rigorous processes linking the evidence to the recommendations. Specifically,...
The 2017 International League Against Epilepsy classification has defined a three‐tier system with epilepsy syndrome identification at the third level. Although a syndrome cannot be determined in all children with epilepsy, identification of a specific syndrome provides guidance on management and prognosis. In this paper, we describe the childhood onset epilepsy syndromes, most of which have both...
The goal of this paper is to provide updated diagnostic criteria for the epilepsy syndromes that have a variable age of onset, based on expert consensus of the International League Against Epilepsy Nosology and Definitions Taskforce (2017–2021). We use language consistent with current accepted epilepsy and seizure classifications and incorporate knowledge from advances in genetics, electroencephalography,...
Epilepsy syndromes have been recognized for >50 years, as distinct electroclinical phenotypes with therapeutic and prognostic implications. Nonetheless, no formally accepted International League Against Epilepsy (ILAE) classification of epilepsy syndromes has existed. The ILAE Task Force on Nosology and Definitions was established to reach consensus regarding which entities fulfilled criteria for...
In 2017, the International League Against Epilepsy (ILAE) Classification of Epilepsies described the “genetic generalized epilepsies” (GGEs), which contained the “idiopathic generalized epilepsies” (IGEs). The goal of this paper is to delineate the four syndromes comprising the IGEs, namely childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and epilepsy with generalized...
The International League Against Epilepsy (ILAE) Task Force on Nosology and Definitions proposes a classification and definition of epilepsy syndromes in the neonate and infant with seizure onset up to 2 years of age. The incidence of epilepsy is high in this age group and epilepsy is frequently associated with significant comorbidities and mortality. The licensing of syndrome specific antiseizure...
Objective
We aimed to assess the reliability and validity of single‐item global ratings (GR) of satisfaction with epilepsy surgery.
Methods
We recruited 240 patients from four centers in Canada and Sweden who underwent epilepsy surgery ≥1 year earlier. Participants completed a validated questionnaire on satisfaction with epilepsy surgery (the ESSQ‐19), plus a single‐item GR of satisfaction with...
Objective
To review the evidence of felt and enacted stigma and attitudes toward persons living with epilepsy, and their determining factors.
Methods
Thirteen databases were searched (1985–2019). Abstracts were reviewed in duplicate and data were independently extracted using a standardized form. Studies were characterized using descriptive analysis by whether they addressed “felt” or “enacted”...
Objective
This is a systematic review aimed at summarizing the evidence related to instruments that have been developed to measure stigma or attitudes toward epilepsy and on stigma‐reducing interventions.
Methods
This review followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) standards. A broad literature search (1985–2019) was performed in 13 databases. Articles...
Objective
The relationship between antiseizure medications (ASMs), which improve health outcomes by controlling seizures, and health‐related quality of life (HRQOL) is poorly understood and may involve intermediate variables. We evaluated the potential mediators of the association between ASMs and HRQOL.
Methods
Data are from an outpatient registry of adult patients with epilepsy seen at the Foothills...
Objective
The aim was to compare the outcomes of subdural electrode (SDE) implantations versus stereotactic electroencephalography (SEEG), the 2 predominant methods of intracranial electroencephalography (iEEG) performed in difficult‐to‐localize drug‐resistant focal epilepsy.
Methods
The Surgical Therapies Commission of the International League Against Epilepsy created an international registry...
The coronavirus disease 2019 (COVID‐19) pandemic has affected the care of all patients around the world. The International League Against Epilepsy (ILAE) COVID‐19 and Telemedicine Task Forces examined, through surveys to people with epilepsy (PWE), caregivers, and health care professionals, how the pandemic has affected the well‐being, care, and services for PWE. The ILAE included a link on their...
Objectives
Patient‐reported outcome measures (PROMs) are used widely to elicit patient's self‐appraisal of their health status and quality of life. One fundamental assumption when measuring PROMs is that all individuals interpret questions about their health status in a consistent manner. However, subgroups of patients with a similar health condition may respond differently to PROM questions (ie,...
Objective
The 19‐item Epilepsy Surgery Satisfaction Questionnaire (ESSQ‐19) is a validated and reliable post hoc means of assessing patient satisfaction with epilepsy surgery. Prediction models building on these data can be used to counsel patients.
Methods
The ESSQ‐19 was derived and validated on 229 patients recruited from Canada and Sweden. We isolated 201 (88%) patients with complete clinical...
Objective
This study was undertaken to identify clusters of adult onset epilepsy with distinct comorbidities and risks of early and late death.
Methods
This was a retrospective open cohort study that included all adults meeting a case definition for epilepsy after the Acceptable Mortality Recording date in the Health Improvement Network database for the years 2000–2012 inclusive. Unsupervised agglomerative...
