[Children's sleep disturbances in videoelectroencephalography and polysomnography--preliminary data].

Introduction: Correlation between sleep and epilepsy is one of the most basic issues of pediatric neurology. VideoEEG nad polysomnography play an important role in diagnostic process of seizures occuring during sleep, epileptic seizures as well as parasomnic episodes.

Aim: In this paper videoEEG and polysomnography assessment in diagnosis paroxysmal sleep events in children was done.

Material And Methods: 25 sleep registrations were performed, videoEEG was performed in 23 children with the age limit of 5 years, and two 8-years-old children underwent total polysomnographic examinations.

Results: Examination during sleep time enabled to establish diagnosis of epilepsy in 18/25 children, in 2 children suspicion of epilepsy was made and in 5 epilepsy was excluded. Positive video results were found in 18/25 children and in 7 no clinical symptoms were recorded. Paroxysmal EEG activity was registered in 16 children, in 5 it was abnormal and in 4 it was within normal limits. Frontal epileptic seizures were observed in two children with simultaneous pathological changes in EEG, and in 1 of them in polysomnographic recording.

Conclusions: VideoEEG and polysomnographic examinations in children during sleep are helpful in defining seizure types and parasomnias.
