Answer

Diffuse EEG abnormalities can also be seen as irregularities in maturational indices and organizational states. In addition to the patterns of profound disruption to the ability to organize cyclic states (which are typical of the most severe abnormalities), several patterns of EEG dysmaturity can be recognized and identified. In newborns who are small for their gestational age, transient or persistent dysmaturity patterns can be distinguished by their duration. Quantification may include assessment of interhemispheric synchrony in tracé alternant, typical of QS, or the counting of premature features such as delta brushes.
