The conjugation of psychological indicators and the level of constant potential of the brain for participants in modern armed conflict (pilot study)

Rationale. The specificity of injuries in combatants determines the feasibility of studying the relationship between the state of cerebral energy metabolism (CEM) and changes in the mental sphere to establish the role of adaptive reactions of the nervous system in the development of psychogenic lesions of various levels.

The arm. Compare changes in psychological indicators and the level of constant brain potential in combatants.

Materials and methods. Fifty four combatants were examined. Used methods of neuroenergy mapping, psychological diagnosis.

Results. Compared with the comparison group, combatants had the increased average DC-potential level (Хav.) (69.7 % and 17.6 %, p = 0.031, respectively). An increase in the local DC-potential level in the central and right frontal, the right temporal, central, and left parietal parts of the brain (12.3 (8.1–20.3); 10.1 (7.8–34.4); 8.6 (4.2–17.4); 5.8 (1.1–15.2); 5.4 (3.0–15.3), and 0.8 (-3.1–4.3); -5.8 (-12.1–5.1); -2.2 (-4.9–4.3); 1.7–(-0.7–5.4); 0.1 (-4.9–2.8) mV, р = 0.005, 0.007, 0.011, 0.003, 0.004, respectively) was registered. More than 58.8 % of the combatants had an adaptation violation in the form of a rigid reaction to stress. When modeling physical and emotional stress, correlation ties between the DC-potential level were established in the post-hypertension period and indicators of the test of visual perception (rs = 0.52, p = 0.018), the symptom of acute stress disorder (ASD) “Event of the injury” (rs = 0.52 p = 0.009; rs = 0.54 p = 0.011; rs = 0,53 p = 0.017, respectively).

Limitations. The study is limited by the sample of patients and the lack of clinical characteristics of examined combatants, taking into account psychoneurological conditions.

Conclusion. Violation of physiological adaptation to combat stress is manifested by a rigid reaction of the DC-potential level (Хav.). During functional trials, the conjunction of the reactivity of the cerebral energy exchange with the severity of the symptom of the “Event of the injury”, an indicator of visual perception, reflecting the vulnerability of the right hemisphere, which leads in the development of adaptation and stress.
