Helen A2 - Arzimanoglou, Alexis PY - 2017 T2 - Pediatric Epilepsy AB - An essential step in EEG interpretation is the identification of features that are statistically deviant compared to normative data, a process that defines abnormalities and establishes their significance in appropriate clinical context. EEG patterns evolve with maturation; neonates reveal distinct features that regress within 4–6 weeks after birth to be replaced by patterns characteristic of infancy and early childhood. The patterns also vary with the child's state at time of recording, the level of alertness during wakefulness, and cycling through stages of sleep. Recognizing the considerable variability of normative EEG features is thus a prerequisite to interpretation.
