Study reveals significant brain abnormalities after covid-19

In a new study to be presented at the Scientific Congress of the Radiological Society of North America, researchers found significant brain abnormalities up to six months after COVID-19 infection.

The scientific community has sought to understand the long-term effects of covid-19, especially with regard to neurological health. Symptoms include difficulty thinking or concentrating, headache, sleep problems, dizziness, tingling sensation, change in smell or taste, and depression or anxiety.

For the study, the researchers used a method called magnetic susceptibility-weighted imaging. Typically, this technique helps to understand how much certain materials (such as blood, iron and calcium) will become magnetized in an applied magnetic field, and is often used to monitor a range of neurological conditions, including brain tumors, for example.

Through this technique, the researchers analyzed the data of 46 patients recovered from covid-19 and 30 who were not previously infected.

Results showed that patients who recovered from COVID-19 had significantly higher susceptibility values ​​in the frontal lobe and brainstem compared to healthy controls. The clusters obtained in the frontal lobe mostly show white matter differences.

As experts suggest, these regions of the brain are linked to fatigue, insomnia, anxiety, depression, headaches and cognitive problems.

The researchers also found a significant difference in the right ventral diencephalon region of the brainstem, a region associated with many crucial bodily functions, including coordinating with the endocrine system to release hormones, relay sensory and motor signals to the cerebral cortex.

Now, the idea is to understand whether these brain abnormalities after covid-19 persist in the long term, and for how long they should last in these patients.
