Abstract

Ictal automatisms of fear or sadness, of which the patient is unaware and which are not preceded by a corresponding emotion, have not been well characterized. Of 557 patients admitted for video/EEG monitoring, 2 (0.36%) were identified who had automatisms of fear and sadness. One patient was found to have a sudden ictal expression of sadness of which he was not aware. The second patient showed a sudden fearful expression, followed by oral automatisms, staring, and amnesia for the event. Both patients had left mesial temporal lobe epilepsy. The patient with ictal fear underwent further invasive monitoring and became seizure free after a limited mesial temporal resection. The mesial temporal structures not only mediate emotional experiences, but can also activate stereotyped expressions of fear or sadness without the patient's awareness, arguing for an efferent pathway for expressing negative affects within the mesial temporal lobe.
