An international team of researchers has shown for the first time that the brain injury caused by COVID-19 can cause dementia.
Researchers from the United Kingdom, Australia and Germany published their findings today in the journal Scientific Reports.
The study found that the severity of dementia is linked to the degree of COVID infection in the brain.
The study also found that brain injury is linked with changes in the immune system and changes in brain structure.
The researchers looked at data from more than 100,000 people who were diagnosed with COVID, and compared it to data from the general population.
They found that people with severe COVID infections had significantly more cognitive impairment and brain atrophy than people who did not have COVID.
The findings suggest that COVID is associated with changes to brain structure, which may be associated with cognitive decline, which is linked, in part, to changes in immune system function, the researchers said.
