There has been some discussion on this forum about similarities between the symptoms of B12 deficiency and the symptoms of Long Covid.

One of my main symptoms is brain fog, so I was interested in a brief article loosely connecting the respective symptoms, and possibly treatment, of ADHD and Long Covid.
