My Grandma has recently started on some anti-psychotic drugs and tranquilizers, and they seem to work quite well most of the time. She is going for a CT scan (I think) tomorrow, and they have been told she cannot take her medication for 48 hours afterwards. My Grandad's life is going to be a nightmare for those two days. I don't understand why she can't take her medication, also why is she having a scan when she has AD, it's pretty advanced and it's going to cause all this aggro. What exactly do they want to achieve? I can't ask my Grandad too many questions as she is always there and will get very angry if she thinks he is talking about her.
