Self-induced seizures presumably by peri-orbital somatosensory self-stimulation: A report of two cases

摘要

Self-induced seizures by somatosensory stimulation are rare. We describe two epileptic patients with self-induced seizures presumably by peri-orbital somatosensory stimulation. Two infants with severely delayed psychomotor development and poor visual acuity after acute subdural hemorrhage in early infancy had been diagnosed as having West syndrome. They evolutionally became to show serial self-induced seizures preceded by rubbing eye with finger in one case and touching right eyebrow with the back of left hand in the other case. Video-electroencephalography (EEG) monitoring was useful to confirm self-induced seizure by peri-orbital self-stimulation. In patients with serial seizures preceded by peculiar behaviors, we need to consider the possibility of self-induced seizures, even if they have a history of West syndrome and severe psychomotor retardation.
