Abstract

The use of amplitude-integrated electroencephalography (aEEG) to assess brain function and detect seizures has been increasing worldwide. Results from previous studies have demonstrated that seizure patterns can be recognized as transient rises on aEEG traces. We report here a case of an infant with neonatal seizures that showed paradoxical transient drops on aEEG traces. The ictal EEG showed initial low-amplitude fast rhythmic activity followed by epileptic recruiting rhythms and high-voltage slow waves. Therefore, downward patterns on aEEG traces should be recognized as suspected seizure patterns.
