Depression can cause memory issues but it is very difficult to differentiate between PCS caused memory issues and depression caused memory issues.

Anxiety can do the same.

But, once one become focused on a memory struggle, they can become magnified, not in reality, but in perception.

Many memory issues are due to lack of focus. Anxiety can cause lack of focus.

I would caution you against comparing your memory to your peers. You will never be able to make any sense of that. Just too many variables.
