I suppose it is not well reported.
I think certain meds can have a big effect on cog fog, as well as other dx's like fibromyalgia (fibro fog).
I was on no pain meds - only Ibuprofen types for pain as needed - my only rx was lipitor ( possibly a co factor).
I only mentioned it to my doctor as a "this is also happening" thing.
Mine was a work comp claim so sure didn't want them thing I was going crazy or something.
I didn't really want to tell her how much it was concerning me - that I was really beginning to feel like I had begun to feel like I had severe ADD & even early onset Alzheimer's for awhile early on.

I felt really out of it for awhile...
Totally lost the ability to multi task, even crowds or multiple conversations distracted me, could say the words I was thinking of or couldn't think of the word I wanted to say..
it was crazy weird...
