Abstract
The review presents an analysis of literature sources devoted to the study of changes in the nervous system in patients with vibration disease. Vibration-mediated cellular hypoxia, which occurs as a result of spastic changes in blood vessels, phase fluctuations in intravascular pressure, impaired blood and lymph outflow, causes suppression of energy metabolism, contributes to disorders at the level of receptor (glutamate, GABA-ergic, dopamine and cholinergic) and synaptic structures, conductors of pain and temperature sensitivity (demyelinization), analyzing neurons in the parietal region of the brain, regulatory proteins of the nervous tissue (NF-200, GFAP S-100). A low-amplitude, irregular, disorganized and sometimes deformed EEG spectrum with a predominance of the alpha wave and a shift of the alpha rhythm to the left reflects changes in the spontaneous electrical activity of brain structures in patients. With an increase in the experience dose of vibration-noise exposure, the dominant alpha activity changes to slow-wave or polyrhythmic. Mild and moderate diffuse changes in the brain become focal in nature, cortical-subcortical relationships are disrupted at the diencephalic level, creating a pathophysiological basis for sensorineural (sensory-neural) hearing loss, especially in patients with a genetic predisposition mediated by genes encoding proteins of the heat shock system. The psycho-emotional status of patients is characterized by a hypochondriacal focus on the state of health, mental disadaptation, psycho-emotional disorders in the form of anxiety, depressive mood. The analysis of literature sources on the mechanisms of the formation of neurological disorders in patients with vibration disease revealed the lack of data on the state of the multicomponent ghrelin system interacting with GHSR-1A and GHSR-1B receptors, which determines a new vector in further experimental and clinical studies.
