Hi, ku. I haven't seen brain fog described like that on the forum, nor has that been my personal experience, though I'm lucky to have had only minimal problems with this thus far.
Most people report a general slowness and difficulty thinking through concepts that formerly were relatively easy, as though their brains were navigating mud. Mixing up words and forgetting names of things are common issues. The steps of accomplishing something are forgotten or done in the wrong order. I can remember not being able to get my act together to pay bills, for instance. By that I mean simple things like finding pen and checkbook, etc., then dealing with the stack of papers.
Has your son been evaluated for seizures? I did read your post where you said he has a lot of neurological issues and may have MS, but he could be having seizures as well. I'm certainly no expert on anything, but I have read descriptions of types of seizures that sound very much like what you've described.
I do hope you get to the bottom of things soon.

The Dr. increased his neurotin yesterday. He told me he was not having a seizure if I pinched him (no I didn't lol!) and he felt it. I see it much worse during the episodes he has. I do see what you are saying often. Sometimes it is much worse than others. Somedays he is just beside himself and gets so frusterated when he reads something or tries to write something and it just doesn't happen or it's really slow. He started sleeping again after school for several hours so my guess is we are getting ready to do another episode soon. Whatever this is goes in cycles from pretty good to ok and then not so good. It has improved with the Neurotin. Maybe a higher dose will help more. I just don't know but we have had a pretty good last couple of weeks. I am thankful for that. Thanks so much!
