Seem to be happening more and more but my dad's memory is slowly fading away with the MS.
This week for example I told him after I took him for a scan Monday that we would get the results Thursday and I'd pick him up at 12 noon. He called me Tuesday night asking if he should order a steak and cheese or am I still coming over. Then Wednesday he couldn't remember why and who we were seeing Thursday. It breaks my heart to see a once sharp man slowly descend into a shell of himself. I worry about him daily.
