ABSTRACT

Objective: to show the results of the use of video electroencephalogram in the evaluation of undetermined neurological paroxysmal events and/or difficult epilepsy in pediatric patients.
Methods: one hundred and 21 children (aged 5.90 ± 4.34 years), divided into 4 groups according to the objective of the video-EEG based study, were researched on. This study was aimed at 1) determining the nature of the paroxysmal event -either epileptic or not-; 2) confirming the epileptic syndrome; 3) quantifying the epileptic attacks; and 4) studying candidates for epilepsy surgery.
Results: the diagnostic efficacy was 86.77 % and caused changes in diagnosis and/or in the initial treatment in 32.38 % of cases. Changes in diagnosis of group I occurred in 16 out of 43 patients (2 epilepsies, 7 movement disorders, 4 sleeping disorders and 3 psychogenic crises). Forty seven epileptic syndromes were classified in the second group (11 focal epilepsy, 31 generalized epilepsy and 5 undetermined). The number of recorded crises was 7.31 ± 4.21 in the third group and the video-EEG recording time was 3.6±1.10 hourº s. Two patients in the fifth group were studied and confirmed as candidates for functional hemispherectomy.
Conclusions: video-electroencephalogram monitoring ratified that it is a very useful tool in the diagnosis of neurological paroxysmal events in children, which influences in setting a proper therapeutic behaviour and in assisting in the reduction of certain restrictions for the application of the International League against Epilepsy criteria.
