Relations between blood supply of brain of students and condition of autonomic nervous system and risk factors

Abstract

The purpose of our research was to estimate the brain blood supply level by rheoencephalography method in junior students of the Medical academy and to determine the blood supply links with the autonomic regulation state, behavioural and alimentary factors. Rheo-encephalographic study, research of the autonomic nervous system state, heart rate regulation and questioning of 17–29 year-old students have been conducted. Basic hemodynamic indices were normal in all surveyed students. Increase in body weight index enhanced the probability of the brain blood supply deterioration. Adaptation mechanisms tension was accompanied by reduction of the rheographic index. Higher blood filling of the brain vessels corersponded to higher ratio “blood minute volume / due blood minute volume” defined taking into account the system arterial pressure. The quantity of links with indicators of the autonomic nervous system state was limited. Nonlinear dependence of the rheographic index on the Kerdo vegetative index was observed: the rheographic index value was the lowest in students with the autonomic balance by the Kerdo vegetative index; it was the highest in the group with the sympathetic prevalence. Risk factor of blood filling decrease was the reduction in the diet variety when foodstuffs of different groups were included into the diet less than twice a week, or they were excluded from the diet completely. Positive correlation of blood supply was observed more often with frequent consumption of fish, vegetables, and fresh fruits. Increase in the regular alcohol intake experience promoted decrease in brain blood supply and increase in asymmetries of blood supply indicators. The effect of alcohol was essential, despite young age of surveyed students and low level of alcohol consumption. Increase in the experience and intensity of smoking was accompanied by deterioration of brain blood supply indicators. Students with the best blood supply had the better academic progress. Observed multiple correlations of blood supply indicators with behavioural factors allowed to assert that reduction of risk factors (control of body weight, variety and full value of a diet, refusal of smoking, alcohol restriction even below doses which are considered safe) would allow to improve the brain blood supply.

Psycho-Emotional and Functional State in the Process of Intuitive Thinking

“…The activation of brain by the cognitive activity requires the adequate metabolic maintenance and, first of all, the intensified oxygen supply which is achieved by the blood supply intensification [18]. It was established that in a quiet state, the degree of oxygen saturation of arterial blood hemoglobin of the students with the low level of intuition development was 92.2% and it was positively increasing up to 94.5% while the students were doing the tasks connected with intuition ( fig.…”

Assessment of the Functional State of the Cardiovascular System of Students

“…The problem of preserving and strengthening the health of the population, especially young people, remains the most urgent for the state. Throughout his life, a modern person is constantly in various stressful circumstances that are associated with social, economic, and psychological changes (Korovina, Zaporozhets, Kozakevych, 2019). The most vulnerable are student youth, since the rhythm of their life is hypodynamic with simultaneous significant intellectual and emotional loads.…”
