Magnetoencephalography Evaluation of Febrile Seizures in Young Children

The aim of this study is to assess any cerebral dysfunction in young children, who experienced febrile seizures, by, population means of magnetoencephalography. Our study included 15 children (9 boys, 6 girls) within the age range of 2 to 7 years. The magnetoencephalography data were recorded with a 122-channel biomagnetometer. Equivalent current dipoles were calculated for epileptic spikes on magnetoencephalography recordings according to the single dipole model. Of 15 children, 8 showed equivalent current dipoles that located at the left-temporal, right-temporal, occipital, and frontal lobe, as active regions responsible for febrile seizures. We assumed that the interictal epileptiform discharges are a consequence of febrile seizures. Of course, further study in a larger number of patients is needed to evaluate the exact role of the equivalent current dipoles, in young children, who experienced febrile seizures.
