I'm not a healthcare worker but I definately suffered from cognitive deficits fro Lyme. I got sick almost 20 years ago and was diagnosed after being sick for almost a year.
I could no longer be an engineer, my 3-D spatial orientation was gone, I couldn't read blueprints. I couldn't function at all for about 4 years. I still have deficits; short term memory problems, problems speaking. Despite years of meds including IV, plus herbs and anthing else I could find, I am not back to the way I was. I believe I have permanent brain damage from the Lyme. I lost years of college, I have whole blocks of skills that are lost. Some days, I can help my kid with his pre-calculus, other days, I'm lucky if I can do pre-algebra. Since I had a total math brain, this is a huge loss for me.
I was eventually able to find a new "career". After 8 years with the same organization, I now make less than 20% of what I made 20 years ago as an engineer and I work harder.
