Fixation-off sensitivity in a girl with symptomatic occipital epilepsy admitted in non-convulsive status epilepticus
Brief report/Clinical case, 91 - 94Tag this article
Fixation-off sensitivity occurs mainly in children with idiopathic occipital epilepsies, with only few cases reported in symptomatic epilepsies. We describe an 8-year-old girl with a history of symptomatic epilepsy admitted in non-convulsive status epilepticus. The video-EEG revealed the presence of high-amplitude occipital paroxysmal activity, which occurred continuously as long as the eyes were closed and with other conditions of fixation-off, and were inhibited when eyes were opened. Initially this phenomenon was unrecognized and misdiagnosed as simple partial status epilepticus, being treated energetically, and achieving control of discharges. We discussed the unique phenomenon of fixation-off sensitivity, which can electrically mimic an epileptic status.
