Like RW when I was diagnosed it was O.N. and cognitive stuff. I found it got worse during the heat. Don't you live in a hot climate, Kitty? Yes, it is so frustrating to have the word recall problem!! And every once in awhile I say something backward or use a word that makes no sense at all in the sentence and everyone around you kind of laughs! I did find that when I went on Tysabri most of this went away.
