FUNCTIONAL ACTIVITY OF THE BRAIN IN ELDERLY WOMEN OF THE ARCTIC ZONE OF RUSSIAN FEDERATION WITH DIFFERENT VEGETATIVE TONE

Abstract

The aim of the study was to identify the characteristic features of brain activity according to the distribution of the DC-potential level in elderly women with different levels of vegetative tone living in the Russian Arctic. Materials and methods. In a cross-sectional simultaneous study, differences in the indicators of DC-potential level were considered in three groups of elderly women with different levels of vegetative tone: vagotonics, normotonics, sympathotonics. A total of 121 elderly women permanently residing in the territory of the Russian Arctic were studied. Registration of the DC-potential level of the brain was carried out using a 12-channel hardware-software diagnostic complex "Neuro-KM". The assessment of the autonomic regulation of the heart rate was carried out using the hardware complex "VNS-spectrum". The results of the study. Significant differences were found in the neuroenergy exchange of the brain in normotonic and sympathotonic women in the frontal and temporal regions. Significant differences between sympathotonics and vagotonics were revealed in the frontal areas in the right and left leads. Factor analysis was used to obtain data on the localization of predominant brain activity in elderly women with various types of vegetative tone. Conclusions. The study of the functional activity of the brain in elderly women with different vegetative tone demonstrated the presence of specific changes in the distribution of values of the constant potential level, which may indicate some change in the mechanisms characterizing the state of cerebral energy exchange.
