  • Title: Ictal smile.
    Author: Molinuevo JL, Arroyo S.
    Journal: Epilepsia; 1998 Dec; 39(12):1357-60. PubMed ID: 9860074.
    Abstract:
    PURPOSE: Smiling is sometimes manifested during partial seizures. Its value for localizing the epileptogenic focus is not known. We analyzed smiling as an ictal manifestation possibly useful for seizure localization. METHODS: We reviewed patients referred to the video-EEG monitoring unit who presented a smile as part of their critical symptoms. Ictal smile was defined as an accordant expression accompanied by other characteristic epileptic symptoms and ictal EEG activity. RESULTS: Five of 86 patients experienced partial seizures with an ictal smile. We observed smiling during parietal (two patients) and temporal lobe (three patients) seizures. The right hemisphere appeared to be involved with greater frequency. CONCLUSIONS: Ictal smile is an uncommon manifestation of partial seizures involving temporal or parietal lobes, localized mainly on the right hemisphere.
