Neuroenergy exchange of the brain acts as a significant indicator affecting the preservation of neuropsychic activity in elderly age The aim of the study was to identify the features of the DC-potential level in various periods of old age in women living in the Arctic zone of the Russian Federation. The study involved 192 Northerners who were divided into age groups: 1 — 60-64 YO; 2 — 65-69 YO; 3 — 70-74 YO. The evaluation of cerebral energy exchange indicators was carried out by the hardware and software diagnostic complex "Neuroenergometer-KM" "Statokin". Registration of the DC-potential level was carried out monopolarly from 12 leads esTableished in accordance with the international scheme 10-20.
In the studied groups of elderly women, there is a change in the median values of the DC-potential level, demonstrating pronounced fluctuations in the distribution of brain energy consumption in the aging process. Brain metabolism decreases with age, but in old age there may be a multidirectional change between glucose metabolism and acid-base balance, indicating oxidative stress.
Then, at the age of 65-69, there is a gradual development of mental and physiological compensatory mechanisms, which leads to a relative normalization of neuroenergy exchange of the brain. The next increase in the DC-potential level of the brain begins to be traced at the age of 70-74 years. Probably, it is at this age that the decline of physiological compensatory processes begins to occur.
The obtained results made it possible to identify the peculiarities of the distribution of the DC-potential level in women of different age groups and to esTableish normative values. The developed standards will improve the quality of diagnostics of the functional state of the brain in women living in the Arctic Zone of the Russian Federation, and will also allow timely monitoring brain functional changes in aging.
