- The problem of “maturity/immaturity” in EEG age features’ estimation in children with consequences of perinatal CNS disorders was considered. The author analyzed his own data and suggested that the criteria of age formation of biorhythm structure should be based not upon alpha-rhythm frequency features only but upon its definite spatial organization (presence of rhythm parietooccipital focus) also. Statistical analysis of power spectrum of EEG basic rhythms demonstrated its description criteria validity in clinical practice (visual patterns). It was also shown in the longitudinal survey that EEG type was formed in early childhood and along with some changes of separate parameters (such as frequency, rhythm amplitude) it reserved its basic features upon the criterion of rhythm spatial organization in high degree of probability. The presence of “immature” biorhythm age structure was the risk marker for education/socialization problems at various stages of child development. The isolation of this EEG type at early ontogenesis stages allowed to take up-to-date measures in order to minimize such risks and to optimize the process of age standard load mastering by such children. The absence of activity pathological forms was not the sole marker for “normal” EEG correspondence.
