Hey Lynda - my dad, with whatever his health issues actually are (just pick a few since we've had so many diagnoses!) has been on Aricept and Namenda for about 7 weeks now. His confusion, speech and memory are better more days. This weeks he's had 4 good days and 3 not so good days while I was there. This is a lot better than what we've had in previous months so I am glad they put him on this and cannot imagine why he wasn't started on it a while ago.
The downside is when he is having a good day and his thinking is clear, he is more depressed and frustrated because he knows how bad off he is, and asks me why he is like this.
