Medical News Today Following infection with SARS-CoV-2, the virus that causes COVID-19, some people experience long-term symptoms, including breathlessness and brain fog.
Scientists have attempted to pin down the precise changes in the brain that might be behind these issues, but results have so far been inconclusive.
A new study using the latest scanning technology focuses the search on the brainstem, a brain region responsible for controlling breathing, among other vital functions.
The researchers identify distinct changes in this brain region in people who were hospitalized with COVID-19. They also showed that the damage is more pronounced in those who experienced more severe disease.
