Zusammenfassung
Die Elektroenzephalographie (EEG) ist trotz der Weiterentwicklung moderner bildgebender Verfahren auch heute noch in vielen Fällen eine unentbehrliche Untersuchungsmethode der neurologisch-psychiatrischen Diagnostik. Dabei spielt das EEG insbesondere bei der Diagnostik und Klassifikation von Epilepsien, der prächirurgischen Epilepsiediagnostik sowie in der Differentialdiagnose unklarer Bewusst seinsstörungen eine herausragende Rolle.
Neben den technischen und physiologischen Grundlagen des EEG wird in der folgenden Übersicht auf die Befundung der normalen und pathologischen EEG-Aktivität eingegangen. Aufgrund der hohen klinischen Relevanz werden insbesondere die spezifischen EEG-Muster im Rahmen des Status epilepticus und der Encephalopathien berücksichtigt.
Summary
In spite of the dominance of modern neuroimaging, the electroencephalography (EEG) is still an essential diagnostic test in many neurological patients. EEG plays an outstanding role particularly in diagnostic and classification of epilepsy syndromes, in presurgical evaluation of focal epilepsies and in differential diagnosis of obtunded patients.
Beside the technical and physiological basis of EEG, this review includes the interpretation of normal and pathological EEG activity. Because of the high clinical relevance, EEG patterns of status epilepticus and encephalopathies were particularly considered.
