EVALUATION OF HEAD BRAIN BIOELECTRIC ACTIVITY ON THE BACKGROUND OF UTERINE BLEEDING IN PUBERTY AGE

Study objective: To evaluate the functional state of the central nervous system in adolescent girls on the background of dysfunctional uterine bleeding by the electroencephalography method. Materials and methods of study. We examined 30 adolescent girls. The mean age was 14.7 ± 2.0 years old. We gave the qualitative and quantitative characteristics of the alpha rhythm: regularity, zonal distribution, modulation, index, amplitude, frequency. To assess the degree and nature of the reactivity of cortical and subcortical brain structures, we performed some functional tests with the opening and closing of the eyes, rhythmic photostimulation and dosed hyperventilation. Results. It is statistically significant that the violation of almost all criteria of alpha rhythm has been confirmed. Most of the patterns indicated the presence of diffuse cerebral nonspecific changes in the regulatory plan. The changes revealed mainly concerned the middle brain structures and were of a mild to moderate functional nature. Summary. The bioelectric brain activity in patients with functional disorders of menstrual cycle was within the age limit. The deviations were of a functional nature. Key words: adolescent girls, dysfunctional uterine bleeding, puberty period, electroencephalography, alpha rhythm.
