Videoelectroencephalography in children with paroxysmal events

The paper presents the crucial role of video EEG, modern diagnostic method, which allowed synchronized recording of clinical status and EEG pattern of the patient. This method gives the possibility to compare these two parameters in term of paroxysmal events. Video EEG allows to diagnosed clinical events associated with bioelectrical discharges (epilepsy), recording of bioelectrical events without clinical seizures, diagnosing clinical attacks without bioelectrical discharges (pseudoseizures) and nonepileptic events (without epileptic character in video and EEG). This method is very useful especially in children and adolescents because of huge polymorphism of clinical signs, more common ambiguous diagnosis in this age and due to heterogeneity of bioelectrical brain function in children. Video EEG monitoring gives the possibility for clinical and electro-physiological interpretation of paroxysmal events and plays a crucial rule in localizing of epileptogenic focus, classification of the seizure, epilepsy type or syndrome. The role of suggestion and placebo is important in diagnosing psychogenic pseudoseizures. The duration of video EEG recording is differentiated and much more shorter in diagnosing the type of the event. Prolonged monitoring is needed in children with drag resistant epilepsy and in pre-operation evaluation.
