[The status of adaptive-compensatory mechanisms after the brain concussion in children].
80 children of preschool age were observed after concussion of the brain. In follow-up from 6 months 3 years clinical-anamnestic and neuropsychologic methods were used. The functions of autonomic nervous system were evaluated according to the results of estimation of initial autonomic tonus, autonomic reactivity, autonomic maintenance of the activity and the data of cardiointervalography. The state of nonspecific systems of the brain was studied with day time polygraphic research with a visual EEG evaluation, construction of histogramms by Fora method, estimation of speed and order of the fading of the components of a rough response. Psychovegetative stress was the ground for neurologic disorders in posttraumatic period. The disorders of adaptive regulation were manifested in exhausting of ergotropic systems with compensatory overstrain of trophotropic mechanisms, resulted in predominance of inhibiting influences with an inadequate response of synchronization on EEG during functional loads. Severity of clinical manifestations and disorders of adaptive regulation were more pronounced in children 1-3 year-old and with hypoxic-traumatic damages of the brain in anamnesis. Disintegration of cerebral activity correlated with the remote period. In the first 6-12 months after the concussion of the brain changes of vegetative reactivity prevailed, after 18 months the alterations in vegetative maintenance progressed.
