Изучение функциональной коннективности головного мозга для разработки лечебно-профилактических стратегий у пациентов с асимптомным каротидным атеросклеротическим стенозом

Abstract

The aim of the study was to investigate the condition of the connectome in patients with asymptomatic carotid atherosclerotic stenosis of more than 60% when using hirudotherapy. Materials and research methods. The examination results of 15 patients aged 60 to 82 years with asymptomatic carotid atherosclerotic stenosis in the range of 60-75% were analyzed. The patients underwent a course of hirudotherapy of 10 sessions. All patients underwent structural and functional magnetic resonance imaging with statistical data analysis at rest, complaints and neurological status were evaluated before and after hirudotherapy course. Results of the study and their analysis. Within the course of hirudotherapy in patients with asymptomatic carotid atherosclerotic stenosis when analyzing the neurological status and complaints, a significant improvement of well-being was noted. Functional magnetic resonance imaging identified differences in functional connectivity between medial prefrontal cortex and other brain regions. There was activation in the main structures of the network of controlling and revealing significance. The connectivity between the leading areas of the brain increased, which is a sign of the improvement of the brain activity. Conclusion. The study of connectivity can serve for exploring the work of brain networks and for determining the effectiveness of therapy. A course of hirudotherapy significantly changed the functional connectivity of brain areas, the changes correlated with a decrease in the number of complaints. Such work is a pilot and will be continued in order to further develop treatment and prevention strategies with the inclusion of hirudotherapy in patients with high risk of vascular accidents in sanatorium-resort treatment.
