I also would like to know of carer's thoughts on Memantine and how it has affected their pwd. My dad's been taking it for the past three weeks now having been on Donapezil for years.
His dementia has declined to at least past middle stage and can't do much for himself. Initially he was going to be put on Donapezil and Memantine with the idea of weaning him of Donapezil at some later stage, but the Memory Clinic changed their mind and took him off it completely as his blood pressure was low.
The effect I see is that Memantine appears to make him more alert than before, which might sound good, but it's obvious that he needs sleep that he is now missing, so I'm surprised to read a couple posts say that it's made or can make their pwd drowsy!
I'm hoping that it's just down to the transition from one tablet and his body getting used to another, and thankfully someone from the Clinic will be visiting next week so we can raise these points with them, but I'd love to hear more viewpoints from other carers.
