Abstract

Surface electroencephalogram (EEG) recording remains the gold standard for noninvasive assessment of electrical brain activity. It is the most efficient way to diagnose and classify epilepsy syndromes as well as define the localization of the epileptogenic zone. The EEG is useful for management decisions and for establishing prognosis in some types of epilepsy. Electroencephalography is an evolving field in which new methods are being introduced. The Canadian Society of Clinical Neurophysiologists convened an expert panel to develop new national minimal guidelines. A comprehensive evidence review was conducted. This document is organized into 10 sections, including indications, recommendations for trained personnel, EEG yield, paediatric and neonatal EEGs, laboratory minimal standards, requisitions, reports, storage, safety measures, and quality assurance.

Mise à jour des normes minimales relatives à l’encéphalographie au Canada. L’utilisation d’un électroencéphalogramme (EEG) reste la méthode de référence pour évaluer de façon non invasive l’activité électrique cérébrale. Il s’agit du moyen le plus efficace pour diagnostiquer et catégoriser les syndromes épileptiques mais aussi pour définir l’emplacement des foyers épileptogènes. L’EEG est ainsi utile lorsqu’il s’agit de décider d’un traitement à donner et d’établir un pronostic dans le cas de certains types d’épilepsie. L’électroencéphalographie est aussi un domaine en évolution dans lequel de nouvelles méthodes sont introduites. La Société canadienne de neurophysiologie clinique a du coup constitué un comité d’experts afin d’élaborer, à l’échelle nationale, de nouvelles normes minimales. Pour ce faire, un examen exhaustif fondé sur des données probantes a été mené. Le document qui en a résulté est divisé en 10 sections : directives et recommandations destinées à du personnel qualifié, efficacité des EEG, EEG pédiatriques et néonatales, normes minimales en laboratoire, demandes d’EEG, production de rapports, conservation, mesures de sécurité et assurance de la qualité.
