Peculiarities of damage of CNS functional state and cerebral hemodynamic at the children with consequences perinatal encephalopathy

Abstract

Influence of natal cerebrospinal traumas on ischemia of a developing brain, especially under action press is known. The special importance is given to infringements circulation vertebrobasilar region (VBR). Changes of CNS functional state (on data EEG) at disturbance cerebral hemodynamic (on data rheoencephalography) in VBR and carotid artery region was investigated. We investigated 92 children in the age from 5 to 9 years (mean 7,0±2,1) with the complaints to head pain, parasomnia, tiredness and difficulty in training.

Influence of natal cerebrospinal traumas on ischemia of a developing brain, especially under action press is known. The special importance is given to infringements circulation vertebrobasilar region (VBR). Changes of CNS functional state (on data EEG) at disturbance cerebral hemodynamic (on data rheoencephalography) in VBR and carotid artery region was investigated. We investigated 92 children in the age from 5 to 9 years (mean 7,0±2,1) with the complaints to head pain, parasomnia, tiredness and difficulty in training. The 2 groups the surveyed children among with moderately expressed (I) and sharply expressed (II) by changes of bioelectrical activity, mainly in parietal-ocipital (P-0) and posterior temporal (T5, T6) areas of a head brain are allocated. In the first group (10 person) in the specified areas dominated hypersynchronous alpharhythm (frequency 8-10 Hz, amplitude up to 100 mkV). For the present group the moderate decrease of amplitude intracerebral pulse waves (AIPW) in VBR on rotation of a head on 30-40%, from reference values with 0,1 on 0,17. Om was characteristic at safe reactivity of microvessels of a channel on delay of breath at 90 % of the children. The second group (15 person) differed by instability of a functional state with alternation alpha-rhythm and theta-waves (4-6 Hz, 80-120 mkV). Such instability is found out at sharply expressed (up to 45-70%) decrease AIPW in VBR on rotation of a head. In 67% of cases was marked as non-reaction of microvessels of a channel on delay of breath. This groups were united by relative safety AIPW in VBR in limits of norms for ages and increased tonus of vessels in carotid arteries region and VBR. Thus at 30 % of the children both groups were decreased AIPW up to 0,1-0,12 Оm (N=0,15-0,17 Оm). Received data allowed to connect a degree of changes of a cerebral cortex functional state and cortical-subcortical relations with depth of infringements cerebral hemodynamic for the account compression influences in system spinal and basic arteries at the children with consequences perinatal encephalopathy.
