Abstract
|
|
|
Background: Confusional arousal is common and usually considered benign. However, nocturnal epilepsy should be ruled out because there are many overlaps between parasomnia and nocturnal epilepsy.
Methods: We searched the patients who underwent video-EEG monitoring for diagnosis of confusional arousal. Initial and final diagnostic impressions and clinical courses were reviewed.
Results: Among the four cases of confusional arousal, two cases turned out to be parasomnia, and the other two to be epilepsy. The diagnosis was open to debate in all cases, before or even after video-EEG monitoring.
Conclusion: Differentiation between parasomnia and nocturnal epilepsy is diagnostic challenge. Both clinical features and ictal monitoring with EEG covering the whole scalp are necessary for diagnosis.
