Clinical and electro physiological examination of patients with chronic cerebral ischemia (CHEM) due to arterial hypertension was carried out. The main neuropsychiatric syndromes were identified: asthenic, neurotic and cephalgic. The functional state of the brain was evaluated by electroencephalography (EEG). EEG changes, especially during functional tests,indicated the inclusion of adaptive mechanisms that support the functional capabilities of the brain in conditions of formation of chronic cerebral ischemia and the need for treatment and preventive measures.Key words:chronic cerebralischemia, arterial hypertension,electroencephalography

The aim: To monitor the brain functional state of generally healthy Ukrainian schoolchildren according to computer electroencephalography (EEG). Materials and methods: EEG examination of 125 practically healthy (according to medical records) schoolchildren of both sexes, which were divided into 3 age groups: 1) 8–12 years old (n = 49); 2) 13–16 years old (n = 42); 3) 17–18 years old (n = 34). EEG was recorded at rest with eyes closed and during functional tests (eye opening, hyperventilation). Visual and spectral analyzes of the EEG were carried out, types of EEG were determined according to A.E. Zhirmunskaya. (1991) in the adaptation of N.L. Gorbachevskaya et al. (1999). Results: The peak frequency of alpha activity is in the range of 9 to 11.5 Hz, with a tendency to increase as you grow older. A disorganized type of EEG with a predominance of alpha activity dominates with an organized type of EEG. For most schoolchildren, normal EEG reactivity predominates in response to functional tests. The detection rate of short fragments of pathological activity in the background did not exceed 8%, but increased to 20% with hyperventilation. Conclusions: Only a third of modern Ukrainian schoolchildren classified as “healthy” have a physiological type of EEG, which indicates the optimal functional state of the brain. The remaining part of generally healthy schoolchildren have EEG changes, which reflect initial functional disorders mainly at the level of nonspecific structures and the brain stem.

The purpose of the study. To study clinical and neuroimaging features of chronic cerebral ischemia (CCI) in polycythemia vera (PV).Materials and methods. 66 patients with PV were examined – the main group (43 men, 23 women; mean age 62.0 ± 3.4 years), of which 64 (97.0%) patients were diagnosed with CCI. The comparison group consisted of 85 patients with CCI (34 men, 51 women; mean age 67.7 ± 4.6 years), who developed against the background of cerebral vascular atherosclerosis and arterial hypertension. To identify cognitive disorders, we used Mini Mental State Examination (MMSE). Insomnia was studied in accordance with the criteria of the International Classification of Sleep ICDS‑22005. The quality of sleep was determined using a questionnaire from the Federal Somnological Center. Neuroimaging (MRI of the brain) was performed on Siemens Symphony 1.5 T and GE Signa 1.5 T tomographs.Results. Subjective symptoms CCI are characterized by a greater representation of asthenic and insomniac disorders. Transient ischemic attacks in patients with PV are significantly more common than in the comparison group, their frequency depends on the duration of PV. The revealed changes in MRI of the brain in the majority of PV patients with CCI are characteristic of multiinfarction vascular encephalopathy; in the comparison group, changes that characteristic for subcortical arteriosclerotic encephalopathy were more often recorded.

In the article the features of bioelectric activity and magnetic resonance imaging of the brain in patients with chronic cerebral ischemia (CCI) are exposed on the background of stable angina of the voltage ІІ and ІІІ ФК. 90 subjects (61 men and 29 women) (mean age 60.6 ± 7.8 years) were examined in the main group and 30 persons (10 men and 20 women) (mean age 55.2.6 ± 5.5 years) control group aged 45 to 74 years. The analysis of data of the conducted complex neuroimaging examination of patients with ССI on the background of stable angina was collected and provided. Based on the data obtained using neuroimaging techniques, it has been established that in patients with CCI, against the background of stable angina, the course of the disease is associated with the risk of development of the acute cerebrovascular accident.

Arterial hypertension (AH)is currently considered the most significant risk factor for the development of not only acute cerebrovascular accidents and chronic cerebral ischemia, but also disorders of memory and other cognitive (cognitive) functions. Numerous studies have proven the connection between persistent increase in blood pressure (BP) and the risk of the onset and progression of cognitive impairment. The positive dynamics on the part of clinical and hemodynamicparameters is explained by the fact that gliatilin improves thetransmission of nerve impulses in cholinergic neurons; positively affects the plasticity of neuronal membranes and receptor function. Gliatilin improves cerebral blood flow, enhances metabolic processes in the brain, activates the structures of the reticular formation of the brain and restores consciousness in traumatic brain lesions.

The purpose of this research was to study the features of the comorbid course of ischemic diseases of the visual organ and chronic cerebral ischemia in atherosclerosis. The material for this study was the results of complex examinations of 37 patients (74 eyes) with ischemic diseases of the visual organ in combination with chronic cerebral ischemia and atherosclerotic vascular lesions. In addition to complex ophthalmologic examination, ultra¬sound examination with color Doppler mapping of ex-tracranial and intracranial segments of the great vessels of the brain, Color-Doppler sonography and magnetic resonance imaging of the brain with tractography were used to study the peculiarities of the course of ischemic diseases of the visual organ in chronic cerebral ischemia. The quantitative characteristics of blood flow in the ves¬sels of the eye and brain were the maximum systolic, final diastolic speeds, resistance index, carotid – ophthalmic ratio.

Background. Treatment of chronic cerebral ischemia should be aimed both to the main etiological factor and to the pathogenetic mechanisms of cerebral ischemia and hypoxia. The action of ozone therapy is characterized with a multilateral positive effect on the main aspects of chronic cerebral ischemia pathogenesis, such as chronic cerebral hypoxia, impaired microcirculation, rheological disorders, and activation of lipid peroxidation. The use of iodine-bromine baths in chronic cerebral ischemia has been proved to be accompanied by an improvement in cerebral circulation, normalization of the brain bioelectric processes, an initially impaired condition of the autonomic nervous system, and an increase in the level of adaptive capabilities of the body. Aim: to develop effective pathogenetically substantiated methods for the combined use of iodine-bromine baths and ozone therapy in patients with chronic cerebral ischemia to increase the effectiveness of health resort treatment. Methods. In accordance with the tasks set in the work, 90 patients with chronic cerebral ischemia of the degree 1, who were randomized into three treatment groups, were examined and treated. Patients of the control group (n = 30) received iodine-bromine baths, patients of the comparison group (n = 30) received ozone therapy, patients of the main group (n = 30) received iodine-bromine baths and ozone therapy. Examination of patients included Doppler ultrasound, electroencephalography, rheoencephalography, сardiointervalography, lipid metabolism studies, fibrinogen content studies. Results. As a result of treatment, the improvement of clinical symptoms and the normalization of biochemical and neurophysiological parameters were noted in patients of all treatment groups. Overall efficiency (improvement and significant improvement) was 53.3% in the control group, in the comparison group it was 63.3%, and 73.3% in the main group. Conclusion. The authors proved the practicability of rehabilitative treatment of early forms of vascular diseases of the brain at the stage of sanatorium and resort rehabilitation, which is due to significant compensatory reserves and high plasticity of the structural and functional formations of the brain with preserved ability to develop nonspecific elements of the nervous tissue and restore reversibly damaged structures.

Breathing plays a leading role in ensuring human life processes. Breathing exercises promote the formation of a certain breathing rhythm in accordance with the muscle movements produced. Each sport requires the formation of its optimal functional state. In bullet shooting, an athlete does not experience intense physical exertion, but must show high coordination, attention and psychological stability. The paper presents an assessment of the effectiveness of the use of breathing exercises as a means of recovery for athletes involved in bullet shooting.  The functional capabilities of the shooters' respiratory system have been studied. The assessment of the tolerance of hypoxic load An improvement in the functional capabilities of the respiratory system of shooters, an increase in tolerance to hypoxic loads were revealed. In both groups, there is a positive effect of the course of breathing exercises on the functional state of the respiratory system. The shooters showed a higher increase in the indicators of functional tests than those who do not go in for sports. The inclusion of respiratory gymnastics in the process of sports training as a means of recovery is effective. The course use of breathing exercises made it possible to improve the functional capabilities of the shooters' respiratory system, to increase their tolerance to hypoxic loads.
