Zusammenfassung
Wichtigste Untersuchung bei der Diagnostik epileptischer Anfallsleiden ist das EEG. Es gibt Auskunft zu verschiedenen Fragen:
-
Handelt es sich um ein epileptisches Anfallsleiden?
-
Um welche Art eines epileptischen Anfallsleiden handelt es sich?
-
Wo im Hirn findet diese epileptische Aktivität statt?
-
Wie gut ist die Therapie?
Bei allen diesen Fragen profitiert das EEG von der Möglichkeit, Hinweise auf die Funktion des Gehirns zu geben. Für die Lokalisation struktureller Veränderungen gibt es heute wesentlich bessere Methoden wie das Computertomogramm (CT) oder die Kernspintomographie (MRT). CT und MRT sind zum Nachweis residualer und akuter Hirnstrukturveränderungen ebenso wie die Nativaufnahme des Schädels zum Nachweis dysplastischer Zeichen, die Liquoruntersuchung bei Verdacht auf entzündliche Genese der Anfälle und die Angiographie bei Verdacht auf Gefäßmalformationen sowie zur Charakterisierung tumoröser Veränderungen unverzichtbare Bestandteile der Diagnostik epileptischer Anfallsleiden.
