Background: In recent years, dramatic political changes and the ensuing war in Ukraine have led to a
signifcant increase in the number of stress-related disorders, in particular among military personnel.
The study was designed to evaluate the prevalence and distribution of mental health disorders among
the Ukrainian military referred to inpatient assessment and treatment at a large military psychiatric
hospital located in Kyiv, Ukraine.
Methods: The study was a retrospective analysis of 9109 inpatient admissions to the psychiatric clinic
of national military medical clinical centre in Kyiv, Ukraine, between January 2014 and December
2018. Most of the patients were contracted military service ofcers, 2014-2018.
Results: The population sufered from a wide range of mental illnesses. Neurotic, stress-related, and
somatoform disorders were predominant among the ofcers, while psychotic disorders, personality
disorders, and mental retardation were prevalent among the conscripts. In 2016-2018, the nosological
structure of mental disorders remained stable with the highest prevalence of stress-related and
somatoform disorders, except a decrease in substance use disorders and an increase in psychotic
disorders. Among the outpatients discharged (n=128) in 2017-2018, the majority had sleep disturbances
and fashbacks (73%); anxiety and irritability (84%); and sufered from fatigue and low mood (80.9%).
The level of satisfaction with the social benefts and support from the authorities of the veterans was
extremely low (7.4%).
Conclusion: The study revealed the impact of war trauma on the mental health of the service
members, necessitating the development of specifc preventive measures and digital mental health
tools to support military personnel resource shortages and stigma. 

ABSTRACT The aim: To study the structure of cognitive impairment in patients who were hospitalized with moderate to severe COVID-19 pneumonia. Investigate the correlation with demographic, biochemical parameters, as well as the emotional state of the patient. Materials and methods: Cognitive functions were assessed using the MOCA test.PHQ-9 depression and GAD-7 anxiety questionnaires were used to study psychopathological symptoms. Demographic, clinical and laboratory data were extracted from medical records Results: Cognitive performance is impaired in 94% of patients with COVID-19. This allows to suggest that COVID-19 has a serious impact on cognition, especially in elder people. Among different domains only visuospatial and executive functioning, abstract thinking, attention and delayed recall were severely impaired, while other domains stayed relatively intact. Patients after COVID-19 also tend to have a mild depressive and anxiety state. Anxiety levels were higher than depressive levels, but not connected to cognitive functioning. Also, there was seen a positive correlation between anxiety and pO2 and negative between anxiety and comorbid cardiac pathology. However, this requires further studies to reveal. Another interesting finding was non-linear relationship between cognitive performance and depression, that allows to suggest rapidly evolving depressive mood in persons with severe cognitive impairment after COVID-19. Cognitive and emotional state of patients after COVID-19 was also highly connected with working status. Conclusion: Significant cognitive impairment was presented in almost all patients with COVID-19. There was a selective impairment in domains of visuospatial/ executive functioning, abstract thinking, attention and delayed recall.
