Neurological complications of COVID-19 are not associated with brain damage

The work of scientists from Sweden showed that even after the severe form of COVID-19, signs of brain damage are returned to the norm in the long run. It is really good news for those who complain about neurological complications even a year after the disease.

Scientists still cannot explain the causes of long-lasting symptoms of COVID-19 after recovery and especially neurological complications, which are observed about each third of the third over-time after recovery. Most often, they are manifested by increased fatigue, «fog» in the head and violation of cognitive functions.

The team from the Gothenburg University decided to explore how the indicators of blood biomarkers are changed, which are associated with damage to the central nervous system,

The study was attended by 100 people with a light, medium and severe form of COVID-19. Samples of their blood were analyzed during illness, as well as three and six months after recovery.

Observations have shown that in the acute phase of the disease on oxygen therapy or with artificial ventilation of the lungs in patients, the NFL and GFAP proteins indicating the damage to neurons and astrocytes were increased.

Most often, there were fast fatigue, memory disorders, lack of concentration. It is noteworthy that the severity of the disease did not define differences in the frequency of symptoms, the authors noted.

«Further research should confirm the presence of preserving neurological symptoms and determine their true cause,» the author of Nelly Canberg said. While we see the absence of continuous damage to the brain tissues and good chances of recovery, she added.
