The relevance of the research subject is to explore the neurotic disorders that arise in people affected by the Russian-Ukrainian war and who witness violence and war crimes. The purpose of the research is to reflect the specific features of the mental reaction of children and adults to military actions as an example of global social stress. Bibliographic, bibliosemantic, and statistical research methods were used in the research. Since the beginning of the full-scale invasion, the number of patients with prolonged depression and schizophrenia has increased, and neurotic disorders has become more severe and acute. Particular attention should be devoted to assistance to military personnel who have been in the combat zone for a long time and former military prisoners of war. Attention should be devoted to the psyche, emotionality, and behavior of people with labile and unformed nervous systems—children, adolescents, pregnant women, and people of retirement age.
