Asthenic and cognitive disorders after the COVID-19 infection
Asthenic disorders are one of the most critical and challenging issues in various medical disciplines. Postinfectious asthenia is relatively common. Its major presentations are a significant long-lasting physical and intellectual fatigue. The COVID-19 infection results in numerous emotional, cognitive, and vegetative disorders, drastically reducing the quality of life and preventing rehabilitation and returning to baseline everyday activity. The rationale for introducing the term "post-COVID syndrome" is accounted for by the high prevalence of asthenic, cognitive, and vegetative disorders after the COVID-19 infection and their higher rate compared to other infections and a significant reduction in the quality of life. This paper discusses clinical presentations of the post-COVID syndrome and analyzes the findings on the pathogenesis of this condition. The authors declare that all patients after the COVID-19 infection should undergo the assessment of cognitive functions and asthenic syndrome followed by adequate treatment prescription. The paper describes treatment modalities for the post-COVID syndrome, e.g., the perspective use of Prospecta®, which demonstrated the efficacy for acute and chronic disorders of brain circulation.
