Diffuse spike-wave status of 9-year duration without behavioral change or intellectual decline.

摘要: Summary Continuous, generalized 2.5 to 3.5-Hz spikewave (SW) discharges were evident in an EEG performed 13 h after a first seizure associated with viral illness, 8-year-old girl. On eye opening, the abnormality was suppressed and replaced by delta activity brief spike-wave paroxysms. No alteration consciousness seizures or behavioral abnormalities accompanied findings. Based on EEG, she diagnosed as having “diffuse electrical status,” rare phenomenon that occurs during wakefulness without changes. Although child completely normal clinically, findings persisted 9-year-follow-up period. Ethosuximide (ESM) 1 gr daily resulted temporary disappearance of bioelectrical status. During last 2 years medication finding tended be restricted posterior regions.
