The purpose of the present work is to study the changes in vestibular pathological reactions in persons who were involved in liquidation of Chornobyl nuclear power plant accident and suffer from discirculatory encephalopathy in dynamics after the disaster. Vestibular dysfunction occurs before the development of dyscirculatory encephalopathy. We have determined the specific features of disorders of vestibular-vegetative reactions. They are manifested by cardiovascular disorders and syncopal states. We didn’t find any pathologies of the digestive organs in patients. The effectiveness of hirudotherapy consists in the regulation of the physiological processes of excitation and inhibition, in contrast to drug therapy, because some drugs have a stimulating effect and others a sedative one. In addition, hirudotherapy in combination with rehabilitation measures in patients with dyscirculatory encephalopathy and vestibular dysfunction is effective for maintaining vitality and prolonging life. The renaissance of hirudotherapy and the further study of its possibilities at the modern level is promising for further development of medicine in present and in future.
