FUNCTIONAL ASSESSMENT OF MRT AND EEG RESULTS OF THE BRAIN OF YOUNG PILOTS IN THE INTERESTS OF MEDICAL-FLIGHT EXAMINATION

Abstract

Background. Nowadays, objective assessment of fitness for flight work is an important component in the prevention of early morbidity and prolongation of professional longevity in pilots. Magnetic resonance imaging of the brain as a method of neuroimaging is mandatory. Studying and analyzing the obtained MRI data of the brain of young pilots in comparison with electroencephalography data provides a functional approach to determining fitness for flight work and prognosis of professional longevity. Aim. To study the frequency and structure of various forms of brain structure changes using MRI of young pilots to ensure their examination within the framework of medical and flight expertise in comparison with electroencephalography data. Materials and Methods. A total of 320 pilots diagnosed as healthy were included in the study. The median age characteristics were 19.0 [17.0; 25.0] years. The study design was an empirical, single-moment study. All pilots without identified contraindications (n=320) underwent a contrast-free magnetic resonance study of the brain. An electroencephalograph-analyzer was used to record EEG. The data were recorded under standard conditions in a silent darkened room. Results. When evaluating the results, it was found that in 307 (88.2 %) cases the EEG data were within the age normal range. In group 1 patients (without any MRI features in the liquor system) 40 (11.5 %) people were found to have changes in the form of decreased total cortical electrogenesis in the form of the presence of alpha rhythm in occipitotemporal and temporal leads, as well as beta rhythm predominantly in the right cerebral hemisphere. In a single case (0.3 %) of a young pilot T. from group 2 (with the presence of dilatations of liquor spaces in various brain localizations) EEG changes showed no clear amplitude accent. At this patient's MRI dilated liquor spaces up to 10 mm in the posterior cerebellar region were visualized. Conclusions. Based on this study, the advantage of MRI in assessing intracranial changes in determining the degree of young pilots' fitness for military service has been proved. the data obtained indicate that the incidence of intracranial changes differs significantly from the figures presented in the available literature. Electroencephalography in comparison with brain neuroimaging is a functional method in determining the state of health of young pilots, but a significant number of structural features of intracranial formations determined by tomography are variants of normal anatomy and have no abnormalities on electroencephalography.
