Specialists of the Russian Federal Biomedical Agency (FMBA) talk about the possibility of mental disorders after COVID-19.
Large-scale studies on the basis of the Federal State Budgetary Institution of the Federal Center for Brain and Neurotechnologies of the FMBA of Russia, anxiety disorders and cognitive impairments are especially often observed in elderly people, suffering from chronic heart failure and atherosclerosis of the brachiocephalic arteries, as well as in people with a low level of education.
The appearance of cognitive problems is influenced by respiratory failure, the introduction into an artificial coma during mechanical ventilation and hypoxia caused by insufficient oxygen in the blood. The more common causes are concomitant diseases, social isolation, stress, and damage to nerve cells by a virus.
Studies have shown that 50% of patients demonstrate moderate cognitive impairment: “Anxiety-depressive disorders were detected in 21.6% of cases, asthenic disorders – in 83.3% of patients.” Those who have undergone the coronavirus complain of slow speech and memory impairment.
Earlier, the American Association for the Advancement of Science EurekAlert warned that COVID-19 could lead to the appearance of Guillain-Barré syndrome, the main manifestations of which are impaired coordination of movement, numbness of the feet and hands, and muscle weakness.
