Hi there
I agree with Lisa that that's a pretty odd statement for the rheumy to make
Brain fog is a very typical lupus problem. There are varying degrees and for many people they'll see a huge improvement when their disease activity is correctly managed. For other people their CNS or Neuro Psychiatric involvement may be more marked and more serious.
I think I'd strangle my rheumy if she dared say that (maybe that's why she hasn't tried :lol

. That said, although she does take my cognitive problems on board, I have a hard time getting her to do anything about them. That might, of course, be because there's little else she can do med wise with me for the moment other than put me on much stronger medication that isn't really justified for other reasons (always weighing up the pros and cons of too little/too much).
My neuro listens more on that score but again can do little right now as infuriatingly (but also I suppose happily) little shows up on MRIs etc. and therefore, once again, heavier treatment is not justified.
My brain fog problems did improve quite a bit when my disease activity became more controlled but I have still been left with pretty severe problems which mean work has become impossible. I'm a translator and, although I can still speak English quite easily I tend to forget words a lot and need to correct writing/typing much more than before.
My second language is French and that is the big problem. I've been speaking it every day for the last 19 years and suddenly it's deteriorated severely. I make a hash of things when speaking and can no longer make the relation between French and English. When I'm tired (which let's face it is pretty often) I can't remember more than three words in a sentence and if I read the sentence purely from a comprehension point of view can't make head or tail of it
Added to that are the things Lisa mentions, short term memory loss (even medium term really), not being able to assimilate what people say - I hear it but can't understand a word, forgetting things and people I've known all my adult life...
I'm sorry I can't help more but maybe you'll find it is some consolation to know you are not alone.
You might find these links interesting on the subject of lupus memory and other cognitive problems.

P.S. I have moved your thread to symptoms. I think the forum is better suited to your question.
