The coronavirus has caused the death of more than 3.3 million people and has impacted the health of more than 161.2 million worldwide. Even though scientists have been fighting COVID-19 for more than a year, there is still much to discover.
Of all the sequelae that this disease produces, the most notorious is respiratory distress. But it is known that there are many others, among which are hair loss, chronic headache, heart disease, and many more.

Now, a new study has found that patients who underwent oxygen therapy and who had high temperatures show a reduced volume of gray matter in the frontal-temporal region of the brain.
This new research, carried out by scientists at Georgia State University and the Georgia Institute of Technology, in the US, revealed that this decrease in the volume of gray matter was associated with COVID and a higher level of disability, even after six months after being discharged.
Specialists used CT scans of 120 neurological patients, 58 of them positive for COVID-19, and 62 were the control group.
Likewise, the researchers found that the volume of gray matter in this region was significantly reduced more in patients who received oxygen therapy compared to patients who did not receive it. The same happened with the patients who had high fevers.
They concluded that COVID-19 can affect the frontal-temporal region through fever or lack of oxygen.

The researchers hope to replicate the study in a larger sample size that includes many types of brain scans and different populations of COVID-19 patients.
