I'm on Entocort which is also a steroid, and when I read your post I realised that I have the same problem!!! Sometimes when I'm talking I stop because I can't remember a specific word I want to use, or I think that I have to do something and seconds later I wonder, "what was it that I wanted to do?". I also mix up my daughters names, I call for Alexandra and I mean Marina, then I call for Marina and I mean Alexandra, my girls find it so funny, but I don't!!!
I didn't have this kind of problem before, and I'm only 34, so I hope as soon as I taper Entocort, my memory skills will improve!!!
