12 minutes agoCOVID infection can cause brain changes, suggests a study
Periskopi(4 years ago)
(4 years ago)Scientists found significant differences in the MRI scans (magnetic resonance images) before and after the COVID-19 infection. Even after a slight infection, the overall size of the brain had diminished slightly, with less gray matter in areas related to smell and memory.

Even after a slight infection, the overall size of the brain had diminished slightly, with less gray matter in areas related to smell and memory.
Researchers do not know if the changes are permanent, but they emphasized that the brain can heal.
The UK Biobank project has been following the health of 500 thousand people for about 15 years and has a database of scans recorded before pandemic, so it provided a unique opportunity to study the long-term health effects of the virus.
The overall size of the brain in infected participants had contracted between 0.2 and 2 percent, Klonkosova conveys. tv
There were losses in the gray substance in sniffing areas, linked to smell and memory-related regions. Those who had recently recovered from COVID had little more difficult to perform complex mental tasks.
But researchers do not know whether the changes are returnable or are really important to health and well - being.
We need to remember that the brain is really plastic with this implies that it can heal itself so there is a very good chance that, over time, the harmful effects of infection can be alleviated”, said lead author Gwenaelle Douaud, from the Wellcome Centre for Neuroimazhe Integrative, at Oxford University.
