My mom tried Aricept. It gave her diarrhea. She didn’t like that it kinda upset her stomach. She switched to Memantine. AKA Namenda. She has handled it fine. It’s hard to say it helped. She still has ended up losing her ability to talk and understand language and she is losing other memories as well. My dad was on Exalon patches. You had to be careful about touching them. You had to place them on different places on his body each time: left front, right front, right back, left back. I remember the adhesive left rings like he had fought an octopus. He was also on Aricept. Again, it’s hard to say if it helped. None of the meds make them better. They stave off sup for a while. That’s why it’s hard to tell the efficacy, as far as I know.
