[Features of the status of the nervous system of children with different levels of biological development].

The results of neurological examinations of 818 children of the late pre-school age distinguished for different levels of the biological development (determined on the basis of morphological criteria) are presented. Most children examined were healthy. A connection between the characteristics of the neuropsychic state and the level of the biological development was disclosed. These characteristics were the best in children whose biological age corresponded to the officially-registered one. A risk of certain neurological pathologies in children with different levels of the biological development was determined. All this shows that a greater attention should be paid to the protection of the nervous system in children with a delayed or an accelerated biological development.
