Has anyone elses IQ dropped since becoming sick?. I have noticed a pattern - when I am sicker my IQ is really bad and I can not for the life of me understand information that I previously would have not had a problem understanding. When I get a nasty illness on top of the ME, such as epstein barr virus or influenza, it gets even worse. When I had epstein barr virus back in 1999 and 2001, I completely lost the ability to work out how to connect up my tv and video, which I could previously do with my eyes closed!. 3 years ago when my health was in a much better place, I could understand complex scientific info, now I have trouble understanding even the most basic info. I feel really dumb!. Anyone notice a pattern like this?. I remember watching the "cdc coverup of cfs" youtube video and a guy on there from the incline village outbreak, said his IQ dropped by 20 points - I can believe that!!.
