Electroencephalography after confusional arousal termination

EEG 30-second epoch, longitudinal bipolar montage, after confusional arousal termination. Within a few minutes, the patient returned to baseline, his responses became appropriate, and he remembered the code phrase given to him during the middle of the episode but was amnestic to conversations early in the spell. EEG demonstrates intermixed alpha and beta frequencies, his usual waking baseline.
