Several months after infection with the SARS-CoV-2 coronavirus, even relatively young patients often show impaired cognitive processes. Let us remind you that thanks to them we gain knowledge and skills, thanks to which we can cope in everyday life. The study showed that people treated in hospitals are in the most trouble. What exactly is happening to these people?

  1. It is known that COVID-19 is a threat not only to the respiratory system, but also to the nervous system. The result is, among others brain fog
  2. It turns out that complications of COVID-19 can negatively affect the intellect, also in relatively young people
  3. Studies have shown that patients hospitalized and treated in the emergency department had greater difficulties than those treated outpatiently
  4. The greatest disturbance was noticed in the speed of information processing, but there are more problems

How COVID-19 Affects the Brain. Test

Scientists from the Icahn School of Medicine recall in the pages of the JAMA Network Open that people who have had COVID-19 often complain of cognitive disorders, including the so-called brain fog.

  1. “Brain fog” attacks not only after COVID-19. When can it occur? Seven situations

To further investigate the effects of the disease on intellectual status, the authors of the new publication tested 740 volunteers aged 38 to 59 who had developed COVID-7,6 an average of 19 months earlier. None of the participants suffered from dementia.

The research included, inter alia, concentration, working memory (the maintenance of information needed to complete the current task), executive functions and various aspects of speech.

Influence of COVID-19 on the intellect. What are the biggest problems?

Tests have shown quite common damage in people after COVID-19. The greatest losses were noticed in the speed of information processing – 18 percent., executive functions – 16%, influencing the speech of the so-called phonemic / letter fluency – 15 percent (it is about entering words beginning with a specific letter or sound), verbal fluency – 20%, memorization – 24%. and recalling information – 23 percent

  1. Neurologist: COVID-19 is highly traumatic, patients are like soldiers returning from missions

Patients hospitalized and treated in the emergency department had worse results than outpatients.

– In this study, we detected a relatively high incidence of cognitive decline a few months after contracting COVID-19. In people admitted to the hospital, the most noticeable were deficiencies in executive functions, information processing speed, verbal fluency, remembering and recalling information – the scientists write in their work.

Cognitive impairment doesn’t just happen after COVID-19

These results are in line with previous reports of cognitive impairment after COVID-19 as well as other viral diseases (such as influenza), the researchers said.

In their opinion, the detected problems may be important for the functioning of patients, e.g. in the professional field and for their state of mind.

Researchers note that the elderly are usually the most vulnerable to cognitive impairment caused by diseases, but in the presented study, the problems also affected relatively young people.
