Relevance. The level of suicides, according to several authors, is one of the most significant indicators of mental health in society, including in the armies of the world.Intention. To analyze suicides and their existing prevention system in the Russian Federation population and Armed Forces in 2007–2018.Methodology. Mental disorders and behavioral disorders (F00–F99 by Chapter V, the International Classification of Diseases of the 10th revision) were analyzed according to 3/MED Form in the military units, where ≥ 80 % of the military personnel served. The longterm trends of the main statistical indicators of suicides and mental disorders among military personnel compared to the Russian population have been established.Results and Discussion. In 2007–2018, the level of suicides in the Russian Armed Forces was (12.00 ± 1.35) per 100 thousand military personnel and was 1.7 times lower than in the population of Russia (20.12 ± 1.56) per 100 thousand (p < 0.001). The level of suicides seems to decrease among the military personnel of the Russian Armed Forces. When analyzing the longterm incidence of mental disorders and the level of suicides in the personnel of the Armed Forces of Russia, no significant correlation was found. At the same time, in a cohort of officers and ensigns, a statistically significant correlation was established between the level of suicides and the general incidence of the Chapter V diseases (r = 0.87; p < 0.01), including stressrelated neurotic and somatoform disorders (F40–F48; r = 0.72; p < 0.01), mental and behavioral disorders associated with the use of psychoactive substances (F10–F19; r = 0.89; p < 0.001). In the military conscripts, there was a correlation between the level of suicides and general morbidity related to Chapter V diseases (r = 0.72; p < 0.05), including personality and behavior disorders in adulthood (F60–F69; r = 0.81; p < 0.01) and organic, including symptomatic, mental disorders (F00– F09; r = 0.76; p < 0.05). It was revealed that among the officers and military personnel under the contract, family and domestic causes of suicide prevailed in contrast to the draft servicemen. Meanwhile somatic and mental diseases as a predominant cause of suicide accounted for a relatively small proportion.Conclusion. Psychoprophylactic measures should be aimed at early detection of servicemen prone to suicidal behavior, effective assistance in resolving militaryprofessional difficulties and domestic problems, as well as at improving their adaptation to military service. Special attention should be paid to the early detection of people with addictive disorders, especially alcohol abusers.

Introduction. Alcoholism and opioid addiction are the leading problems of modern narcology and together with adaptation disorders create a significant contribution to dismission from the ranks of the Armed Forces. Identifying the latent forms of mental disorders is of particular importance for making expert decisions at invoking. Special MRI techniques allow to evaluate the functional and microstructural connectivity of distant parts of the brain.Materials and methods. With the application of functional MRI and tractography, 405 patients were examined from the potential conscription pool: 76 patients with alcohol dependence syndrome, 170 with opioid dependence syndrome, and 9 with adaptation disorders. In patients suffering from adaptation disorders, opioid dependence and alcoholism, an analysis of the neural network of the passive mode of the brain was performed.Results. There was established, comparing to the control group, all the patients suffering from addiction demonstrated a weakening of the functional connections of all brain structures. Compared with the control group, the patients with drug addiction and alcoholism had microstructural deformation between the cortical and subcortical structures, especially between the amygdala and the hippocampus. The weakening of functional and microstructural links in the network of the passive mode of the brain in groups of drug addicts indicates that they have violated the processes of control, thinking and the correct decision making. In case of adaptation disorders, integral bilateral differences in terms of global and local node efficiency between groups of patients with adaptation disorder and healthy individuals showed a higher significance of the network of passive mode of the brain in the system of mutual functional connectivity of the posterior cingulate cortex and preclinical. The data obtained create the basis for the creation of biomarkers for patients suffering from mental disorders, which can be used to examine, guide and evaluate the treatment of this pathology.
