OBJECTIVE: To analyze neurological, psychological and psychiatric aspects of COVID-19, as well as to study the current state of the problem. MATERIAL AND METHODS: The study included 103 patients with COVID-19. The main research method was clinical/psychopathological. To study the impact of activities related to the care of patients with COVID-19 in a hospital setting, the medical and psychological state of 197 hospital workers involved in the treatment of patients with COVID-19 was assessed. The level of anxiety distress was assessed with the Psychological Stress Scale (PSM-25), distress indicators corresponded to values of more than 100 points. The severity of anxiety and depressive symptoms was assessed using the Hospital Anxiety and Depression Scale (HADS). RESULTS: When considering psychopathological disorders in the context of COVID-19, it is necessary to distinguish between two main groups of disorders: mental disorders during the pandemic, and mental disorders directly caused by the causative agent SARS-CoV-2. The analysis of psychological and psychiatric aspects in various periods of the initial stage of COVID-19 showed that each of them was characterized by specific features depending on the nature of the influence of different pathogenic factors. In the structure of nosogenic mental disorders in patients with COVID-19 (103 patients), the following clinical forms were identified: acute reaction to stress (9.7%), anxiety-phobic disorders (41.7%), depressive symptoms (28.1%), hyponosognosic nosogenic reactions (20.5%). At the same time, the majority of the patients had manifestations of somatogenic asthenia (93.2%). A comparative analysis of neurological and psychological/psychiatric aspects of COVID-19 showed that the main mechanisms of the impact of highly contagious coronaviruses, including the SARS-CoV-2, on the central nervous system are: cerebral thrombosis and cerebral thromboembolism, damage to the neurovascular unit, neurodegeneration, including that induced by cytokines, and immune-mediated demyelinating nerve damage. CONCLUSION: Neurological and psychological/psychiatric aspects of COVID-19 should be taken into account both at the stage of disease treatment and in the post-infection period due to the pronounced neurotropism of SARS-CoV-2 and its effect on the neurovascular unit. Along with helping patients, an important aspect is the preservation of the mental health of medical personnel working in hospitals for infectious diseases, due to special working conditions and a high level of professional stress.

OBJECTIVE: To study neurological and mental disorders associated with the inapparent and mild course of COVID-19. MATERIAL AND METHODS: The study included 50 patients (mean age 35.2±11.4 years) admitted to a psychiatric hospital due to depressive spectrum disorders. Patients were divided into two groups: patients (n=16) who had IgG antibodies to SARS-CoV-2 (main group) and patients (n=34) without a history of COVID-19 (comparison group). RESULTS AND CONCLUSION: Patients of the main group showed a difference in the structure of asthenic disorders compared with the comparison group. Also, there was a significant predominance of the severity of asthenic symptoms and anxiety in the structure of psychopathological disorders in depressive spectrum disorders. The viral intoxication contributes to the formation of a kind of asthenic «soil¼ (with characteristic manifestations). In the future, in the case of the development of any stress-associated disorder, more pronounced psychopathological disorders are noted compared with patients of the comparison group. The authors describe a variant of the course of COVID-19, in which the development of ischemic stroke was the first clinical manifestation of the disease. These disorders are based on the pronounced neurotropic effect of SARS-CoV-2 and its effect on the neurovascular unit.
