Alte Methoden: Der heutige Stellenwert der Elektroenzephalografie (EEG)

Zusammenfassung

Nach Jahrzehnten Erfahrung des klinischen Einsatzes sind die diagnostischen Möglichkeiten und Grenzen des EEGs inzwischen gut einschätzbar. Der klinische Einsatz erfolgt vor allem bei Epilepsien, Encephalopathien und Parasomnien. Die Übergänge zwischen physiologischen Varianten-Mustern und pathologischen EEG Mustern sind altersabhängig und teilweise unscharf. Umso wichtiger ist eine klar strukturierte und systematische EEG-Auswertung, um Über- und Fehlinterpretationen zu vermeiden. Diese Übersicht beleuchtet den heutigen Einsatz der EEG.

Abstract

Decades of clinical experience enable assessment of the diagnostic yield of EEG and its limitations. EEG is a useful tool in the diagnostic evaluations of epilepsy, encephalopathy and parasomnias. Differentiation between physiological variants and abnormal EEG patterns depends on age, and the borders between the 2 are sometimes blurred. A clear and systematic approach to EEG reading is all the more important to avoid over-reading and misinterpretation. This review addresses the current use of EEG.
