Objective. COVID-19 is increasingly recognized as a systemic disease, and we are seeing more and more disorders of the nervous system, one of which is cognitive impairment, which has a significant negative impact on mental health, social maladaptation, quality of life [1]. Mental health disorders are closely related to COVID-19 at the biological, psychological, and social levels, and they are receiving more and more attention now [2]. Mental disorders may be the manifestations or complications of acute COVID-19, such as acute psychotic disorders, cognitive impairment, anxiety disorders, sleep disorders, depression, and suicide attempts [2]. The study of cognitive impairment in patients with COVID-19 is the basis of neuropsychological rehabilitation for those who need it. It is important to urgently minimize the potential negative impact on cognitive and psychosocial functions and quality of life of patients with COVID-19 [3]. Methods. Cognitive function was examined using the MOCA test in 60 patients with COVID-19 viral pneumonia as part of psychiatric screening on admission to the hospital. The study group of patients was represented by 34 (57%) men and 26 (43%) women. The age of patients ranged from 35 to 81 years (mean age was 62.4 years). 55 patients (92%) from the study group denied the presence of any organic or other mental disorders. 2 patients (3%) reported a previously diagnosed depressive disorder, 1 patient (2%) reported a bipolar disorder, and 2 patients (3%) reported an anxiety disorder. Results. 95% of inpatients with COVID-19 pneumonia had cognitive impairment of varying severity. Severe cognitive impairment was in 30% cases, in 47% - moderate -, in 18% - isolated, mild cognitive impairment, in 5% - no impairment. Data analysis shows both the presence of general cognitive dysfunction in patients with viral pneumonia COVID -19, and a more noticeable violation of its separate components: visual-spatial, executive functions, thinking, attention, slow reproduction (long-term memory) (p <0.01).The most noticeable were violations during the performance of tasks on visual-spatial, executive functions (2.25), thinking (1.1), slow reproduction (long memory) (1, 7), attention (4.8,) (p <0.01). It should be noted that almost all patients had no violation of recognition (3), orientation (5.8), and sequential subtraction (2.4) (p <0.01). Conclusions. A study of patients hospitalized with COVID-19 pneumonia revealed cognitive impairment of varying severity. In addition, the largest violations of individual components were identified, such as visual-spatial, executive functions, thinking, attention, slow reproduction (long-term memory). Recognition, orientation, and sequential subtraction are almost intact. The dynamics of disorders of individual components of cognitive functions, such as recognition, orientation, sequential subtraction, differs significantly from dementia. In the acute period of COVID-19 disease, studies of cognitive function have been performed, which may indicate that cognitive impairment may have reversible consequences. Identified cognitive impairments were taken into account when drawing up individual plans for neuropsychological rehabilitation. No conflict of interest
