ABSTRACT
The electroencephalography (EEG) of the neonatal period differs significantly from the EEG of the older child and adult. The electrical activity also varies depending on the conceptual age reflecting the maturation of the brain. This variability presents various evaluation challenges for neurologists. In this article, pathological findings (ground rhythm abnormalities and paroxysmal abnormalities) of EEG in newborn period are described.
Keywords: Electroencephalography; prognostic classification; newborn
