Current long COVID science


Thread breaking down this Washington Post article.

Earlier this year, the UK Biobank neuroimaging study showed that even mild covid can lead to an overall reduction in the size of the brain, with notable effects in the frontal cortex and limbic system. These findings help explain the profound anxiety, depression, memory loss and cognitive impairment experienced by so many long-covid patients.

In fact, their symptoms are similar to mild to moderate Alzheimer’s disease, or the type of brain injury seen in cancer patients after chemotherapy and in ICU survivors with post-intensive care syndrome.

The bad news is that this neurological injury is occurring most frequently in younger long-covid patients (20 to 50 years old) who were never hospitalized for covid. The good news is that, at least in some patients, it may not be permanent or progressive.
