Crying seizures.

We report seven patients with crying during video-EEG-documented simple or complex partial seizures. During simple partial seizures, crying occurred with or without appropriate affect. Crying occurred postictally in two patients and was associated with persistent spiking in one of them. Six patients had ictal activity in the nondominant hemisphere, maximal in the anteromesial temporal region in five and in the mesial frontal region in another. These cases support theories proposing a lateralization of emotion, with right hemisphere dominance for negative affective states.
